Introduction
Hwa-Byung is a cultural-related mental syndrome that reflects the cultural characteristics of Korean in DSM-IV. This syndrome is caused by anger or resentment towards unreasonable social violence and trauma.
ObjectivesThe purpose of this study is to revise and validate the ’Hwa-Byung scale’, which can be used to diagnose Hwa-Byung and evaluate the severity of its symptoms.
MethodsTo begin with, the factors of the Hwa-Byung scale were set based on the previous studies. Additionally, the respective subfactors were generated by the semi-structured interviews with these patients. Based on these factors and previous studies, a 142-item pool was developed and verified by six Oriental Neuropsychiatrists. A pilot study was conducted on 50 patients with Hwa-Byung and the main study for the validation was conducted on 200 Hwa-Byung patients. Item analysis, internal consistency, and exploratory/confirmatory factor analysis were performed. Lastly, this study analyzed the ROC curve to present the diagnostic cut-off score of the scale.
ResultsAs a result of analyzing the content validity of the item pool, we constructed a preliminary scale. We excluded the inadequate questions from the pilot study results. In the main study, The Hwa-Byung scale showed high internal consistency and its items were suitable for the factor structure. Finally, we suggest an optimal cut-off score of the symptoms sub-scale for screening Hwa-Byung.
ConclusionsOverall, the results of this study indicated the reliability and validity of the Hwa-Byung Scale. Based on these results, we discussed several values and limitations of this study and provided suggestions for further research.

Introduction
Bipolar Disorder (BD) is a disorder in which cognitive function is relatively preserved but social functioning is markedly impaired. Interestingly, studies on BD show that the patients have a strong desire for social rewards. Hypersensitivity to social rewards in BD has not yet been sufficiently examined through experimental methods, although recent studies have pointed out that their reward hypersensitivity is the cause of symptoms and dysfunction.
ObjectivesThe purpose of this study was to investigate whether patients with BD are hypersensitive to social rewards using the social value capture task.
MethodsGroups of 25 BD and healthy control (HC) each completed the social value attention capture task. This task consists of a practice phase in which associative learning of social rewards with specific stimuli occurs, and a test phase in which the stimuli associated with rewards appear as distractors during the participants performing a selective attention task. We also recorded event-related potential (ERP) in the practice phase in order to investigate BDs’ cortical activity for social reward.
Resultsshowed significantly decreased accuracy rate and increased reaction time in the high social reward-associated distractor trials of the test phase in the BD compared to the HC. As a result of analysis in ERP components, P3 amplitude for social reward was significantly greater in the BD than the HC.
ConclusionsBD patients exhibit behavioral and physiological hypersensitivity to social rewards that might contribute to social dysfunction.

Introduction
Hwa-Byung is a mental syndrome classified as a “cultural-related syndrome” which reflects the cultural characteristics of Korea in DSM-IV. Hwa-Byung is caused by anger, which is characterized by feelings of anger or resent about unreasonable social violence and trauma. Kwon et al (2008) had developed self-report measure to assess severity of Hwa-Byung but it has several limitations to use in current clinical settings. Therefore, we investigated opinions of experts who have professionality in giving treatment of Hwa-Byung patients in the clinical settings.
ObjectivesThe present study aimed to reach consent of oriental neuropsychiatrists’ opinions about the direction of revision of the Hwa-Byung scale.
MethodsThe Delphi method is a survey method that induces people to freely present their opinions without face-to-face processes and reaches consent through continuous feedback of survey results while ensuring anonymity. The Consensus Panel consists of 16 experts who are Oriental neuropsychiatrists and have experience in diagnosing patients with Hwa-Byung. A total of four surveys were conducted as consensus was reached on the fourth round. Each questionnaire was distributed by mail to a panel of experts and was asked to submit a response after receiving the questionnaire.
ResultsThe results of the study are as follows. First, common factors for Hwa-Byung include anger, resent/blame, modify memory bias and attention bias for anger events. Second, characteristics of young Hwa-Byung patients include stress caused by social factors and excessive immersion in certain things such as drinking or smoking.
ConclusionsTherefore, when revising the Hwa-Byung scale, it would be necessary to include these factors.

Background:
There is an association between anterior cerebral artery vessel asymmetry and anterior communicating artery aneurysm, presumably based on flow dynamics. The purpose of this study is to investigate the potential relationship between aortic arch branching patterns and incidence of intracranial aneurysm.
Methods:This study included patients scanned over 1 year at our tertiary care center who underwent high-resolution imaging (computed tomography angiography or digital subtracted angiogram) of the head and neck arteries, aortic arch, and superior mediastinum. Exclusion criteria included patients with suboptimal images. Patient age, gender, aortic arch branching pattern, and the presence, location, and number of aneurysms were documented.
Results:Among the 1082 patients analyzed, 250 (23%) patients had a variant aortic arch branching pattern, 22 (8.8%) of whom had aneurysms. There were 104 patients with 126 aneurysms, with majority of patients with normal aortic arch branching pattern (n = 82, 79%). The most common variant was a common origin of the left common carotid artery and brachiocephalic trunk with or without direct origin of the left vertebral artery. Twenty-two patients with aneurysms had an aberrant aortic arch (21%), compared to 232 patients without an aneurysm (24%). Fischer exact test showed no statistically significant difference between the incidence of aneurysm with different aortic arch variant groups (two-tailed p-value = 0.715).
Conclusion:To our knowledge, this is the first study to examine the association between aortic arch branching patterns and incidence of intracranial aneurysm. No significant association was found between aortic arch branching pattern and the incidence of intracranial aneurysm.

Tardive dystonia is an extrapyramidal adverse effect that can arise after prolonged use of dopamine receptor antagonists and is characterized by sustained involuntary muscle contractions frequently causing twisting and repetitive movements or abnormal postures. This occurs most commonly in the head and neck region and can begin as a focal dystonia, which then progresses to a segmental form. The prevalence of tardive dystonia in neuroleptic treated individuals ranges from 0.4% to 4%. Up to half of the patients who develop tardive dystonia tend to do so in the first 5 years of neuroleptic exposure, with onset earlier in males than females. Tardive dystonia tends to be persistent with a low remission rate of 10 percent in 6.6 years. Previous cases of tardive dystonia were mainly reported in patients with schizophrenia spectrum disorders. We report a case of tardive dystonia in a neuroleptic treated bipolar disorder and was treated with clozapine.
Tardive dystonia has been associated with both typical and atypical neuroleptic exposure, such as clozapine, olanzapine, risperidone and ziprasidone. Several authors have suggested the use of clozapine in the treatment of tardive dystonia. The ability of clozapine to treat tardive dystonia may be related to D1 receptor antagonism. There have also been case reports of tardive dystonia treated by olanzapine and quetiapine. Botulinum toxin and dopamine-depleting drugs may also be effective. More recent reports suggested the use of deep brain stimulation of regions such as globus pallidus and subthalamic nucleus in the treatment of tardive dystonia.

Background:
Donepezil is a reversible, centrally-acting acetylcholinesterase inhibitor used in the treatment of mild to moderate symptoms of dementia associated with Alzheimer's disease. in recent years, there has been emerging evidence of its use in other conditions, such as Lewy Body dementia and autism. However, there have been few reports of the use of Donepezil to treat depression in the absence of cognitive impairment.
Methods:This is a case report of a 62-year old female with a long-standing history of major depressive disorder with no history of cognitive impairment, who failed to respond to antidepressants with augmentation therapy including antipsychotics, lithium and methylphenidate; but eventually improved on Donepezil.
Results:A then-56-year old Chinese lady diagnosed with major depressive disorder, was treated with several antidepressants with poor response. Despite augmentation with dual antidepressants, antipsychotics, methylphenidate and lithium, her symptoms of avolition, depressed mood and irritability persisted. After 4 years of antidepressant treatment, she was started on donepezil 5 mg. Within a month of augmentation, significant improvement in symptoms were reported, notably in mood and volition, and the patient was able to engage in an active and meaningful lifestyle of semblance to her pre-morbid mental state.
Conclusion:This case highlights the possibility of Donepezil being used as an adjunctive therapy in major depressive disorder, even in the absence of cognitive impairment. Future studies to investigate the use of Donepezil may therefore be worthwhile to explore its use in this population of patients.

Objective
To search the international literature (any language) for publications reporting outcomes of tracheostomy performed to treat obstructive sleep apnoea in children.
MethodData sources included: Google Scholar, Cumulative Index to Nursing and Allied Health Literature, Embase, Scopus, and PubMed/Medline. Four authors searched systematically through to 20 January 2018.
ResultsA total of 597 studies were screened; 64 were downloaded and 11 met criteria. A total of 196 patients underwent tracheostomy (mean age, 4.2 years; range, newborn to 18 years); 40 had detailed qualitative data and 6 had detailed quantitative data. Apnoea/hypopnoea index showed a 97 per cent reduction (n = 2) and apnoea index showed a 98 per cent reduction (n = 3). Lowest oxygen saturation showed a 34 oxygen saturation point improvement (n = 3). Several patients demonstrated significant improvement in breathing. All identified patients were syndromic, had significant co-morbidities or had severe obstructive sleep apnoea.
ConclusionBased on reports of children who have undergone a tracheostomy, for whom there are pre- and post-operative data, tracheostomy appears to be a successful treatment for obstructive sleep apnoea. However, additional research is recommended given the small number of patients in the literature.

Population decline among Asian horseshoe crabs in Asia is increasingly reported, but knowledge of their population and ecological status in China is limited. We conducted community interviews in 30 fishing villages around Beibu Gulf in Guangxi, China, to collect distribution information about the potential spawning/nursery grounds of Tachypleus tridentatus and Carcinoscorpius rotundicauda, and any imminent threats to their populations. Based on the results from 400 respondents we identified 45 potential spawning/nursery grounds distributed widely along the shores of Beibu Gulf. We visited 10 of these sites and verified the presence of juvenile horseshoe crabs by field surveys. Nearly all respondents reported an overall depletion in horseshoe crab populations from these 45 sites, which they attributed mainly to unsustainable fishing practices. Respondents who reported having seen horseshoe crab mating pairs on shores were mostly older people, which may suggest a considerable reduction in horseshoe crabs coming to the shores to spawn in recent years. The mean daily harvest of adult T. tridentatus offshore, as indicated by fishers, has declined from c. 50–1,000 in the 1990s to 0–30 individuals during 2011–2016. Our Wisdom of Crowds approach, supported by confirmatory field surveys, is a cost-effective method for assessing the population status of horseshoe crabs, and the level of threat they face. Similar approaches with other species are likely to be particularly valuable in the Asia–Pacific region, where well-structured population monitoring is largely unaffordable.

Japan has been free from rabies since 1958. A strict import regimen has been adopted since 2004 consisting of identification of an animal with microchip, two-time rabies vaccination, neutralizing antibody titration test and a waiting period of 180 days. The present study aims to quantitatively assess the risk of rabies introduction into Japan through the international importation of dogs and cats and hence provide evidence-based recommendations to strengthen the current rabies prevention system. A stochastic scenario tree model was developed and simulations were run using @RISK. The probability of infection in a single dog or cat imported into Japan is estimated to be 2·16 × 10−9 [90% prediction interval (PI) 6·65 × 10−11–6·48 × 10−9]. The number of years until the introduction of a rabies case is estimated to be 49 444 (90% PI 19 170–94 641) years. The current import regimen is effective in maintaining the very low risk of rabies introduction into Japan and responding to future changes including increases in import level and rabies prevalence in the world. However, non-compliance or smuggling activities could substantially increase the risk of rabies introduction. Therefore, policy amendment which could promote compliance is highly recommended. Scenario analysis demonstrated that the waiting period could be reduced to 90 days and the requirement for vaccination could be reduced to a single vaccination, but serological testing should not be stopped.

The articles in this forum present many innovative ideas on the role of culture in creativity. In this commentary, we first discuss the contributions of these articles in relation to two recurrent themes: (i) where creativity resides and (ii) what conceptual refinements are needed to push the field forward. Next, we oudine a process model of creativity and explain the role of culture at each stage of knowledge creation. We argue that successful innovation involves one or more iterations of the following three stages: (i) authoring new ideas; (ii) selecting, editing, and marketing new ideas; and (iii) acceptance of the new ideas in the market. The desired outcomes are different at the different stages, and culture influences all stages of the process. Specifically, existing knowledge provides a reference point for evaluating the originality of ideas; assumed cultural consensus provides the normative basis for idea selection, editing, and marketing; and actual cultural norms determine how likely an idea will be accepted in a culture. Furthermore, different social and psychological processes are at work at different stages of the creativity process, and culture can affect the outcomes of the creativity process through its effects on these social and psychological processes.

In June 2011, a cluster of suspected cases of Guillain–Barré syndrome (GBS), which can follow Campylobacter jejuni infection, was identified in San Luis Río Colorado (SLRC), Sonora, Mexico and Yuma County, Arizona, USA. An outbreak investigation identified 26 patients (18 from Sonora, eight from Arizona) with onset of GBS 4 May–21 July 2011, exceeding the expected number of cases (n = 1–2). Twenty-one (81%) patients reported antecedent diarrhoea, and 61% of 18 patients tested were seropositive for C. jejuni IgM antibodies. In a case-control study matched on age group, sex, ethnicity, and neighbourhood of residence, all Arizona GBS patients travelled to SLRC during the exposure period vs. 45% of matched controls (matched odds ratio 8·1, 95% confidence interval 1·5–∞). Exposure information and an environmental assessment suggested that GBS cases resulted from a large outbreak of C. jejuni infection from inadequately disinfected tap water in SLRC. Binational collaboration was essential in investigating this cross-border GBS outbreak, the first in mainland North America since 1976.

The HBsAg status and demographic data of 2480 pregnant women who attended antenatal clinics at Maternal and Child Health Centres in Hong Kong were collected by means of a self-administered questionnaire over a 1-week period in July 1996, to explore the underlying reason of a higher than expected HBsAg prevalence. Local women constituted 49·2% of the sample, mainland Chinese 39·7% and others 11·1%. The overall HBsAg prevalence was 10·0%. When related to place of birth, those born in Hong Kong had a prevalence of 8·4% whereas the prevalence of those born in mainland China was 13·1% (P<0·001). The overall HBsAg carriage rate is high because of a higher rate in immigrants in the community. It is apparent that the HBsAg prevalence of local people in Hong Kong has been decreasing in the past decade. Overall, the current HBsAg carriage rate in the local adult population is estimated to have declined to about 8%.

Malignant mesenchymoma is a very rare head and neck tumour. To date only 15 cases have been reported in world literature and all in children under 16 years of age. We present here a case of a 40-year-old man with malignant mesenchymoma of the retropharyngeal space. The clinical picture is that of progressive dysphagia, voice change, snoring and dyspnoea. CT scan showed a soft tissue space-occupying lesion of the retropharyngeal space which enhanced very well with intravenous contrast. The tumour was excised in toto and the patient given post-operative radiotherapy. Histopathology showed two unrelated differentiated tissue types (bone and fat) in addition to the fibrosarcomatous element thus satisfying Stout's criteria (Stout, 1948) for a diagnosis of malignant mesenchymoma.

In a recent study, Levy and Markowitz [15] demonstrate that, at least for some utility functions, expected utility can be approximated by a judiciously chosen function defined over mean and variance. In addition to resurrecting mean-variance analysis from the limbo into which it was placed by the criticisms of Borch [10] and others, the analysis by Levy and Markowitz yields a more direct approach to portfolio analysis than that provided by the current empirical literature. The current portfolio literature is concerned with notions of efficient sets and systematic risk rather than with utility functions and mean-variance. While much has been gained from a utility-free methodology, it is ultimately predicated upon a separation theorem and, hence, an environment with zero transactions costs. But security markets are not costless and the separation theorem may not hold. In that event, a utility-dependent approach to portfolio analysis could potentially lead to more powerful results especially if such an approach could be empirically implemented.

In recent years a major controversy has formed in the finance literature regarding the empirical evidence of the informational content of dividends. Despite considerable support for the position of dividend nontriviality by various studies, the work by Watts [13] represents a formidable challenge. Because of the close proximity of the firm's earnings and dividend announcement dates, the major issue of the dispute has centered on the identification and control of contemporaneous earnings information. In an attempt to settle this controversy, the present study evaluates and extends Watts' methodology.
