Objective : A variety of approaches are needed to solve high suicide rates in Korean society. Although suicide prevention education has been provided for the public and suicide risk groups in Korea, a systematic discussion of simple, effective suicide prevention guidelines for the general public has yet to be made. Self-help guidelines for suicide prevention, which can help prevent suicide in at risk individuals, will be developed through expert questionnaires. Methods : In order to develop the draft guidelines, suicide prevention self-help phrases were gathered and compiled from homepages and publicity materials of domestic and international suicide prevention and related organizations. A panel of 16 suicide prevention experts conducted primary and secondary surveys using the Delphi method, which derives results from consensus among expert groups. The validity and appropriateness of the guidelines was analyzed using content validity ratios (CVR). Results : Of 33 candidate phrases selected for the suicide prevention guidelines, 9 showed high CVR after the secondary Delphi round. The highest level of support with total agreement was given to 'Do not be alone, stay with someone'. However, more than half of the panelists evaluated 14/27 of the primary Delphi round and 12/26 of the secondary Delphi round phrases as invalid. The researchers completed 10 self-help guidelines for suicide prevention, after eliminating 1 redundant phrase and including 2 additional phrases that showed relatively high CVR. Conclusion : We have developed 10 self-help guidelines for suicide prevention through the consensus of experts. Further studies on the effects of the guidleines relative to suicide rates are needed after widespread dissemination.

Oxaliplatin is a tolerable and effective drug of choice in the treatment of advanced or metastatic gastric cancer. However, it has many dose-limiting neurotoxicities. This study was performed to assess the incidence and types of oxaliplatin-related neurotoxicities. Sixty-four patients receiving oxaliplatin-involved regimen as salvage therapy on metastatic gastric cancer or as the first-line therapy on advanced gastric cancer were evaluated during the period between September 1, 2006 and February 29, 2008. The patients were treated with oxaliplatin 100 $mg/m^2$ and leucovorin 100 $mg/m^2$ simultaneously as 2-hour-lasting infusion on Day-1 followed by 5-FU 1200 $mg/m^2$ as a 22-hour-lasting continuous infusion both on Day-1 and Day-2 by every other week. We developed questionnaires to evaluate patient-recognized neurotoxic symptoms rather than the observer-described events. Surveys were completed at bedside or via telephone interview. Acute and chronic neurotoxicities were graded according to the National Cancer Institute Common Toxicity Criteria (NCI-CTC, version 3) as well as the Oxaliplatin-specific Neurotoxicity Scale. The Grade-3 neuropathy was reported in 19% of the patients (n=12) and grade-1/2 neuropathy occurred in 70% (n=45). The most common symptom was cold-related dysesthesia (83%) regarded as nociperception by the patients. Some patients (19%) experienced functional impairment affecting activities of daily living such as writing, buttoning, and walking. Even though 74% of the patients (42/57) were prescribed with gabapentin to reduce these peripheral symptoms, it did not appear to derive any benefit from this medication. It is suggested that notify the patients about their oxaliplatin-associated, debilitating symptoms, and educate them any self-care strategy at the initiating phase of the chemotherapy. Moreover, it needs to design the intervention studies regarding the prevention and management of the peripheral neuropathy.

Objectives: Unmet needs for dental treatment are one of the potential contributing factors to poor oral health because oral health problems worsen if left untreated. This study aimed to demonstrate the prevalence of and the causes for unmet dental needs, and to evaluate the association between unmet needs for dental treatment and oral health status. Methods: Data on 3,883 subjects aged ${\geq}18years$ from the Korean National Oral Health Survey 2006 were analyzed. Information regarding unmet needs for dental treatment was obtained using standardized questionnaires. Eight trained dentists examined decayed, missing, or filled teeth (DMFT). Multiple regression models were built to assess the association between unmet needs for dental treatment and the DMFT scores. Results: The prevalence of perceived unmet needs for dental treatment was 34.7% among the adult Korean population. Economic constraints were the main cause (38.6%) for unmet dental needs. The average DMFT scores were higher in the subjects with unmet needs for dental treatment than in those without. In individuals with unmet needs for dental treatment within the past 1 year, the number of decayed teeth after adjusting for confounders was likely to be greater by 0.58 and that of missing teeth by 0.27 compared to that in their counterparts with no unmet dental needs in the past 1 year. Conclusions: Perceived unmet needs for dental treatment were significantly associated with poor oral health status among the adult Korean population. Further studies are needed to clarify the direct and indirect effects of unmet needs for dental treatment on an individual's oral health status by investigating critical variables of the causal pathways among perceived dental needs, dental care utilization, and oral health status.

This paper investigates the effects of entrepreneurs' cognitive biases on business opportunity evaluation, given their strong entrepreneurial spirit, which is characterized by innovation, proactivity, and risk-taking. When making decisions related to business activities, entrepreneurs typically make rational judgments based on their knowledge, experience, and the advice of external experts. However, in situations of extreme stress or when quick decisions are required, they often rely on heuristics based on their cognitive biases. In particular, we often see cases where entrepreneurs fail because they make decisions based on heuristics in the process of evaluating and selecting new business opportunities that are planned to guarantee the growth and sustainability of their companies. This study was conducted in response to the need for research to clarify the effects of entrepreneurs' cognitive biases on new business opportunity evaluation, given that the cognitive biases of entrepreneurs, which are formed by repeated successful experiences, can sometimes lead to business failure. Although there have been many studies on the effects of cognitive biases on entrepreneurship and opportunity evaluation among university students and general people who aspire to start a business, there have been few studies that have clarified the relationship between cognitive biases and social networks among entrepreneurs. In contrast to previous studies, this study conducted empirical surveys of entrepreneurs only, and also conducted research on the relationship with social networks. For the study, a survey was conducted using a parallel survey method using online mobile surveys and self-report questionnaires from 150 entrepreneurs of small and medium-sized enterprises. The results of the study showed that 'overconfidence' and 'illusion of control', among the independent variables of entrepreneurs' cognitive biases, had a statistically significant positive(+) effect on business opportunity evaluation. In addition, it was confirmed that the moderating variable, social network, moderates the effect of overconfidence on business opportunity evaluation. This study showed that entrepreneurs' cognitive biases play a role in the process of evaluating and selecting new business opportunities, and that social networks play a role in moderating the structural relationship between entrepreneurs' cognitive biases and business opportunity evaluation. This study is expected to be of great help not only to entrepreneurs, but also to entrepreneur education and policy making, by showing how entrepreneurs can use cognitive biases in a positive way and the influence of social networks.

Objectives: This study aimed to explore dimensions in addition to the 5 dimensions of the 5-level EQ-5D version (EQ-5D-5L) that could satisfactorily explain variation in health-related quality of life (HRQoL) in the general population of South Korea. Methods: Domains related to HRQoL were searched through a review of existing HRQoL instruments. Among the 28 potential dimensions, the 5 dimensions of the EQ-5D-5L and 7 additional dimensions (vision, hearing, communication, cognitive function, social relationships, vitality, and sleep) were included. A representative sample of 600 subjects was selected for the survey, which was administered through face-to-face interviews. Subjects were asked to report problems in 12 health dimensions at 5 levels, as well as their self-rated health status using the EuroQol visual analogue scale (EQ-VAS) and a 5-point Likert scale. Among subjects who reported no problems for any of the parameters in the EQ-5D-5L, we analyzed the frequencies of problems in the additional dimensions. A linear regression model with the EQ-VAS as the dependent variable was performed to identify additional significant dimensions. Results: Among respondents who reported full health on the EQ-5D-5L (n=365), 32% reported a problem for at least 1 additional dimension, and 14% reported worse than moderate self-rated health. Regression analysis revealed a $R^2$ of 0.228 for the original EQ-5D-5L dimensions, 0.200 for the new dimensions, and 0.263 for the 12 dimensions together. Among the added dimensions, vitality and sleep were significantly associated with EQ-VAS scores. Conclusions: This study identified significant dimensions for assessing self-rated health among members of the general public, in addition to the 5 dimensions of the EQ-5D-5L. These dimensions could be considered for inclusion in a new preference-based instrument or for developing a country-specific HRQoL instrument.

Objective: The purpose of this study is to investigate existing evaluation methods and the limitations thereof Korean children's occupational therapists to understand sensory processing performance in schools. This study provides basic data for the development of sensory processing evaluation tools for schools. Methods: The questionnaire was administered to 20 occupational therapists with more than 3 years of experience in occupational therapy interventions for school-aged children. The survey obtained information through online surveys and telephone interviews. The questionnaires were divided into general characteristics and evaluation methods and limitations of existing sensory processing in school, necessity of a sensory processing evaluation tool for school, and opinions. The questionnaire consisted of 12 closed questions and 4 open questions. Results: In total, 90% of the researchers said that school-aged children in schools are aware of 'some information' through their parents or children. Furthermore, 50% said they often complained about difficulties related to sensory processing in school, and 50% that they were more than 'usual'. Finally, 80% of the repondents indicated that the development of sensory processing evaluation tools for schools was "significantly needed". Conclusion: Occupational therapists in charge of domestic children reported for the need to develop evaluation tools to understand sensory processing abilities in schools. Evaluation tools will play an important role in the evaluation and intervention of occupational therapy for school-aged children.
