The purpose of this study is to investigate the Chemistry preservice teachers abilities of developing inquiry questions through applications of inquiry questions development guide, improvement of preservice teachers inquiry question development abilities and analyze types in inquiry questions. Based on literature review related to scientific inquiry questions, the inquiry questions development guide used in this study are developed according to chemistry fields. 27 preservice teachers majored in chemistry participated in this study. In this study, proper inquiry questions suggested by them are comparatively analyzed in terms of level and accuracy . As a result, we can prove that the level and accuracy of inquiry questions after applying the questionnaires are improved more meaningfully than before. Developed questionnaires was effective on developing proper inquiry questions. For developing the inquiry question, the most frequently emerged types of questions by the preservice teachers were unexpected result(34%) , adjustment(20%), how to experiment(14%) , why-how(12%) , relationship between variables’ type (11%) in order. As a result of research for the preservice teachers who participated in the developing inquiry questions, preservice teachers also recognized that the questionnaire has positive effect to develop the inquiry questions. Since the inquiry questions developed by researcher could offer the guide that how the inquiry questions should be suggested to science teachers who teach scientific inquiry, I make a proposition that the inquiry questions should be involved in the professional development program and teacher preparation program.

Objectives : The purpose of this study was to develop the Korean Strength Scale and to examine its validity and reliability. Methods : The Korean Strength Scale is a self-report questionnaire that measures 25 valued strengths and is comprised of 124 items ; each item had a 0-5 rating on a 6-point scale. In order to test validity and reliability, data were collected from 355 adults. The measures included the Korean Strength Scale, HEXACO Personality Inventory (HEXACO-PI), Satisfaction with life scale (SWLS), Positive Affect and Negative Affect Schedule (PANAS), and Orientations to Happiness Questionnaire (OHQ). Results : The resulting exploratory factor analysis of the Korean Strength Scale suggested 4 factor structures. The Korean Strength Scale was shown to have acceptable psychometric properties, including acceptable internal-consistency reliabilities, factorial validity, and high convergent correlations. Conclusion : Although there is room on improvement for some facet scales, the Korean Strength Scale appears to be a useful tool for assessing an individual's signature strengths.

Objective : Being overweight or obesity impairs quality of life and often causes treatment noncompliance in patients with bipolar disorder. This preliminary study evaluated the prevalence of overweight and obesity in inpatients with bipolar mania. Methods : Inpatients with bipolar mania, who were treated with adequate medications at least 4 weeks were included in a retrospective study. The body weight of each patient was measured and the body mass index (BMI) was calculated. Results : Of the 80 patients, 16.4% (N=13) were overweight, and 35.0% (N=28) were obese at discharge. Female patients had higher prevalence rates of overweight and obesity. Being overweight or obesity was associated with the number of previous episodes of depression and combination treatment with atypical antipsychotics and mood stabilizers. Conclusions : Being overweight or obesity is highly prevalent in patients with bipolar mania. Clinicians should pay more attention to weight gain and obesity when prescribing combination therapies. More research is required to identify the impact of specific risk factors for overweight and obesity in patients with bipolar mania.

Eczematid-like purpura of Doucas and Kapetanakis is a type of pigmented purpuric dermatoses. It is clinically characterizedby pruritic seasonal eruptions occurring in the spring and summer, and histopathologically characterized byspongiosis and parakeratosis in the epidermis and by the lymphocyte-mediated leakage of erythrocytes from capillariesin the papillary dermis. We report a case of eczematid-like purpura of Doucas and Kapetanakis that showedclinical improvement with narrowband UVB (NB-UVB). The patient was a 66-year-old man with pruritic,well-demarcated scaly purpuric patches on his feet that appeared 2 months prior. A histopathological study showedmild superficial perivascular lymphocytic infiltration, focal spongiosis with exocytosis, and erythrocyte leakage. Weinitiated treatment with an oral antihistamine, ascorbic acid, and a topical steroid, but the lesion was aggravated. Wetherefore treated the patient with NB-UVB for 6 months, and the lesions regressed progressively with residual postinflammatoryhyperpigmentation.

Kaposi sarcoma (KS) is a multifocal proliferative vascular tumor often caused by human herpes virus 8. Among the four subtypes of KS, classic KS (CKS) is usually chronic, persisting over many years, but is not life threatening. Because the natural history of KS varies, many kinds of therapeutic option for CKS are available and their assessment may be difficult. We experienced three cases of CKS showing HHV-8 positive in biopsy, no history of immunosuppression and HIV infection, normal chest X-ray, no metastasis, and successfully treated with intralesional injection of Pegylated Interferon-α2a (Peg-IFN-α2a). After an intralesional Peg-IFN-α2a injection of 180 mcg/0.5 ml was administered once a week for 4 months, the size and induration of the lesions reduced greatly and the colors faded away. Histopathological examination of the resolved lesions did not show any evidence of KS with negative HHV-8 results. To the best of our knowledge, this is the first report in the literature for the treatment of CKS with intralesional Peg-IFN-α2a injection. (Korean J Dermatol 2014;52(9):646∼650)

Purpose: This study investigated whether parenting stress, work-family conflict, resilience affect retention intent in Korean nurses returning to work after parental leave. Methods: The participants in this study were 111 nurses recruited from 10 hospitals in Korea, who were working after formal parental leave from their hospitals. Collected data were analyzed using descriptive statistics, the t-test, analysis of variance, the Mann-Whitney U-test, Pearson correlation coefficients, and hierarchical regression. Results: Retention intention (33.80±7.78), parenting stress (101.70±17.57), and resilience (85.02±12.75) were at greater than moderate levels and a midpoint level of work-family conflict (29.63±7.00) was noted in this sample of mostly women nurses in their 30s. The factors affecting retention intent were parental leave duration, the number of times that participants had taken parental leave, health condition, work-family conflict, and resilience. The total explanatory power of these variables was 36.7%. Retention intent had a negative correlation with parenting stress and work-family conflict. Conversely, retention intent was positively correlated with resilience. Conclusion: This study supports the need for flexible adjustment of returning nurses’ working hours and family-friendly policies to promote balance between work and family. It is also necessary to develop and apply measures that boost resilience and support health improvement for nurses returning to work.As nurses are often assigned to new areas of work upon return, training programs to aid their adjustment may also be helpful.

Background: Pilomatricoma is a benign, appendageal tumor differentiating towards the normal hair follicles and is characterized by basaloid, transitional, and shadow cells. It is most frequently seen in children; however, a bimodal onset distribution is observed in the first and sixth decades. Objective: The purpose of this study was to analyze the clinical and histopathological features of pilomatricomas in patients over 50 years of age, and to compare these features with those occurring in patients under 20 years of age. Methods: We retrospectively reviewed the medical records and histopathological findings of 73 patients under 20 years and above 50 years of age. The morphological stages of the tumors were analyzed through histopathological findings. Results: The age of patients in the over 50-year age group ranged from 50 to 82 years, with a mean age of 60 years. The male-to-female ratio was 1.1:1. The duration of lesions was from 1 month to several years, with half of the patients having the tumors for over 12 months. The predilection sites were the head (51%), followed by the upper extremities (21%), neck (15%), trunk (6%), and lower extremities (6%). In 73% of the patients over 50 years of age, pilomatricoma was less likely the suspected diagnosis compared with that in the under 20-year age group. Epidermal cysts were most likely suspected in patients over 50 years of age. Histopathologically, half of the tumors were located in the subcutis, which was not significantly different when compared with pilomatricomas in the under 20-year age group. The most common evolutional stage of tumors was early regressive (52%), followed by late regressive (27%), fully developed (15%), and early stage (6%). Capsulation (9%), inflammatory cell infiltration (60%), multinucleated giant cells (36%), calcification (33%), and ossification (12%) were observed. With the exception of capsulation, there were no significant differences in these histopathological features in pilomatricomas in patients over 50 years of age compared with those in patients under 20 years of age. Conclusion: Pilomatrichomas in patients over 50 years of age show no pain, are located in the head and neck, are present for a long duration, and have various clinical presentations when compared with those in patients under 20 years of age. However, they are not rare tumors in adults. Accordingly, pilomatricomas should be included in the clinical differential diagnosis of a solitary, deep skin tumors presenting in adults, especially when they occur on the head.

현재 PTSD와 관련한 여러 병태생리 기전들이 밝혀지고 있으며 이에 초점을 둔 다양한 약물치료가 행해지고 있다. 본 연구에서는 일 대학병원에서 PTSD로 진단된 환자들의 의무기록을 검토하여 약물치료의 경향에 대해 알아보았다.1998년 1월부터 2007년 12월까지 DSM-IV에 의해 PTSD로 진단된 입원 환자 75명이 대상군이 되었으며, 이들의 인구학적 요인들, 입원기간, 외상의 종류, 외상 후 경과시간 및 정신과적 공존병리 및 처방 받은 약물을 조사하였다. 조사 결과, 75명 중 남자는 33명, 여자는 42명이었다. 정신과적 공존병리는 총 50명(66.7%)에서 존재하였으며, 우울장애, 인지장애, 정신장애 및 불안장애 순이었다.73명(97%)의 대상군은 항우울제를 처방 받았으며, 그 중 paroxetine이 54.7%로 가장 많았고 두 가지 이상의 항우울제를 처방 받은 경우도 24%였다. 또 거의 대부분의 환자에서 비정형 항정신병약물(33.3%), 기분안정제(17.3%),항불안제(94.7%)가 항우울제와 병용 처방된 것으로 조사되었다. 여러 제한점에도 불구하고 본 연구에서 얻어진 약물 처방 경향은 향후 국내 실정에 맞는 치료 지침을 수립하는 데에 하나의 근거 자료가 될 수 있을 것이다. Objective : Due to a better understanding of the pathophysiology of posttraumatic stress disorder (PTSD) and the relative limitations in the treatment of patients with PTSD, a variety of medications and treatment algorithms for PTSD have been investigated. This study was conducted to investigate the trends in the pharmacotherapy used in the treatment of inpatients with PTSD at a single university hospital in Korea. Methods : Data from 75 patients diagnosed with PTSD according to the DSM-IV criteria from January 1998 to December 2007 were collected. Demographic data and clinical data, including medications prescribed, were investigated. Results : Thirty-three of the 75 subjects included in this study were male, and 42 were female. Considering psychiatric comorbidity, depressive disorder, cognitive disorder, psychotic disorder and anxiety disorder were reported in order. Approximately 97% of the subjects were treated with antidepressants, including paroxetine in 54.7%, and 24% of the subjects were treated with two different kinds of antidepressants. In addition, atypical antipsychotics were prescribed in 33.3% of patients, mood stabilizers in 17.3%, and anxiolytics in 94.7% of the subjects. Conclusion : In our study, various kinds of antidepressants were prescribed for most patients with PTSD. Antipsychotics and mood stabilizers were added to the treatment regimens of some subjects, and anxiolytics were added to the treatment regimens of most subjects. Despite its many limitations, this study shows the prescription pattern and trends in PTSD treatment in Korea. We hope that these preliminary data would be helpful for the development and integration of a practical guideline for the treatment of PTSD in Korea.

무기체계의 신뢰성이 더욱 강조되고 있는 가운데 무기체계 개발 단계에서는 신뢰도 목표값을 달성하여야 하며, 따라서 신뢰도를 성장 관리하기 위해 체계 수준에서 설정되는 신뢰도 목표값을 하위 수준으로 배정하는 신뢰도 할당은 중요하다. 본 연구는 함정 무기체계의 신뢰도 할당에 관한 연구로서 국방기술품질원에서 수행하고 있는 무기체계의 야전운용제원 RAM(Reliability, Availability, Maintainability) 분석 결과를 활용한 신뢰도 할당 방안을 제시하고 이를 실제 함정 무기체계에 적용하였다. 함정 무기체계의 신뢰도 목표값을 함정 무기체계의 고유한 작업분할구조인 SWBS(Ship Work Breakdown Structure) 그룹에 할당하고 이어서 장비 수준까지 할당하는 절차를 제시하였으며, 유사장비의 고장률 비율에 따라 신뢰도를 할당하는 ARINC 방법을 적용하는 과정에서 야전운용제원 RAM 분석 결과를 활용하여 가중치를 계산하였다. 제시한 신뢰도 할당 방안을 개발이 완료된 함정 무기체계에 적용하였으며, 할당한 신뢰도 값과 신뢰성 시험평가의 기준이 되는 신뢰도 예측값과의 일치성이 개발 시 할당한 신뢰도 값보다 약 22% 향상되었음을 확인하였다. This study developed a reliability allocation method for warship weapon systems using the field data RAM analysis results conducted by the Defense Agency for Technology and Quality and applied it to an actual warship weapon system. As a procedure for allocating the target reliability, it was allocated first to the SWBS group, a unique work division structure of the warship weapon system, and then to the equipment. When applying the ARINC method, which allocates reliability according to the failure ratio of similar equipment, weights were calculated using the field data RAM analysis results. The proposed reliability allocation method was applied to the developed warship weapon system. The consistency between the allocated and predicted reliability, which is the basis for the reliability test and evaluation, was improved by approximately 22%.
