Head-lice infestation, pediculosis capitis, remains a public-health burden in many countries. The widely used first-line pediculicides and alternative treatments are often too costly for use in poor socio-economic settings. Ivermectin has been considered an alternate treatment for field practice. This study was composed of 2 parts, a cross-sectional survey and an intervention study. The main objectives were to determine the prevalence and potential factors associated with head-lice infestation, and to evaluate the effectiveness and safety of oral ivermectin administration. A community-based cross-sectional survey was conducted among 890 villagers in rural areas along Thai-Myanmar border. Females with infestations were eligible for the intervention study, and 181 participated in the intervention study. A post-treatment survey was conducted to assess acceptance of ivermectin as a treatment choice. Data analysis used descriptive statistics and a generalized-estimation-equation model adjusted for cluster effect. The study revealed the prevalence of head-lice infestation was 50% among females and only 3% among males. Age stratification showed a high prevalence among females aged <20 years, and among 50% of female school-children. The prevalence was persistent among those with a history of infestation. The major risk factors were residing in a setting with other infected cases, and sharing a hair comb. The study also confirmed that ivermectin was safe and effective for field-based practice. It was considered a preferable treatment option. In conclusion, behavior-change communication should be implemented to reduce the observed high prevalence of head-lice infestation. Ivermectin may be an alternative choice for head-lice treatment, especially in remote areas.

In this study investigation, 550 high school students attending school in Gyeonggi Area were surveyed for their knowledge of well-being perception. The major findings of the study were as follows: The boys found themselves in a better health compared to the girls. Students recognized the well-being food as all kinds of foods, which can improve their health although they had a significantly different opinion on the other things (p<0.001). The students acquired information on well-being through TV shows and the Internet. The students thought that physical and environmental well- being are the most important. In terms of physical well-being, they emphasized regular workout, balanced diet and enough sleep, while reduction of food waste and the use of disposables along with restriction of behavior not to generate environmental hormone were the important aspect for environmental well-being. In terms of eating-out habits, the girls choose healthy menus more often than the boys, and their menu choice was the most influenced by the information provided by TV and newspaper. Generally, the boys expressed more satisfaction with healthy menus than the girls, but the former didn't have a strong intention to reorder the same menu. Although the boys and girls did not have a same reason to select specific menu, both group choose menu to promote their health. The balance of taste and nutrition was identified as the top priority for their choice of well-being menus.

Background Cutaneous squamous cell carcinoma (SCC), which occurs in keratinocytes of the epidermis and is the second most common skin cancer, has a more invasive growth pattern and higher potential to metastasize than basal cell carcinoma. Total excision of the primary tumor is the treatment of choice. For clear excision of the tumor, invasion depth is one of the most important factors. This study was conducted to clarify the relationship between the size and the invasion depth of cutaneous SCC. Methods Twenty-six cases were collected for this prospective study. Frozen biopsies were examined after complete resection of the tumor, followed by histological confirmation by pathological examination. The major and minor axis lengths of the tumor, the invasion depth, and the level of invasion were measured. Recurrence or metastasis was recorded through regular follow-up. Results The Pearson correlation coefficient was used for statistical analysis. Significant results were observed for the relationship between the major and minor axis lengths and the invasion depth of the tumor (0.747, 0.773). No cases of recurrence or metastasis were observed. Conclusions In head and neck cutaneous SCC, the invasion depth of the tumor is closely related to the major and minor axis lengths of the tumor. Therefore, the invasion depth of the tumor can be estimated by measuring the size of the tumor, and a standard vertical safety margin for head and neck cutaneous SCC can be established, which could be helpful in the development of a preoperative reconstruction plan.

Purpose: To evaluate the effectiveness of percutaneous transluminal angioplasty (PTA) below the knee as a treatment in diabetic foot gangrene. Materials and Methods: Between May 2003 and May 2006, angiography was performed in 35 diabetic foot gangrene classified as either Wagner grade IV or V. Infrapopliteal PTA was performed in 10 patients among them. Clinical success was defined as prevention of major amputation. Results: Among 25 patients who did not receive infrapopliteal PTA, the major amputation rate is 22% (in one arterial occlusion cases), 50% (in two arterial occlusion cases), 63% (in three arterial occlusion cases), respectively. Infrapopliteal PTA was successfully performed in 8 among 10 patients. Two patients were failed and undergone below-knee amputation. Toe amputation were performed in 2 patients with one arterial occlusion. Out of 6 patients with three arterial occlusions, toe amputations were performed in 4 patients and the other 2 patients were healed through debridement. Conclusion: As a first choice revascularization procedure for limb salvage in diabetic foot gangrene, infrapopliteal PTA can be one of treatment options.

The purpose of this study was to Identify the self-actualization level of Junior College Nursing Students and to analyze the variables that may be related to self-actualization. A convenient sample of 346 students were selected from three colleges located in Seoul and Kyungki-Province. The data were collected using a direct survey method from September17to October 2, 1992. The instrument used for this study was the self-actualization test modified by Kim & Lee(1983). The collected data were analyzed using percentages, means, 1-test, X$^2$-test, ANOVA and Pearson’s correlation coefficient, with the SPSSPC$^{+}$ Package. The results of this study are as follows : 1) The self-actualization level of subjects was moderate. The subjects showed higher scores in the areas of Self actualizing Values and Nature of Man than the standardized normal groups. The subjects showed lower scores in the areas of Inner Directed Existentiality, Self acceptance and Capacity for Intimate Contact. 2) The subjects attending day junior colleges showed higher scores in the areas of Time competent, Existentiality and Self Acceptance than those attending college in the evening. The subjects attending evening junior colleges showed higher scores in the areas of Spontaneity than those attending college by day. 3) The junior students showed higher scores in the areas of Feel-ing Reactivity than freshman. The students with no religion showed higher scores in the areas of existentiality than those who had a religion. The group who had the experience of failure on the college entrance examination showed lower scores in the areas of Nature of Man than those without this experience. Those who chose their major voluntary showed scores higher in the areas of I nor Directed, Self Actualizing Values, Spontaneity and Self regard than the unsatisfied group. The group satisfied with college life showed higher scores in the areas of Time Competent, Inner Directed, Self Actualizing Values and Self Regard than the unsatisfied group. In conclusion self actualization level depends on motivation of choice, satisfaction with nursing as a major and satisfaction with college life. Therefore, and effective guidance program is required to improve motivation and satisfaction with nursing as a major and with college life.

Competition between air transportation and railways has grown fiercer in major countries around the world with the rise of high-speed railways. In South Korea, air passenger travel has been rapidly decreasing since the initial launch of the Seoul-Pusan KTX line in 2004 and second opening that followed in 2010. Further expansion of the high-speed railway is expected. At present, research efforts to verify the validity of constructing an underwater express railway tunnel between Ho-nam and Jeju Island are taking place. Considering the possible high speed railway connection between Seoul and Jeju Island, this thesis has analyzed the choice behavior of existing passengers of the major and low-cost carriers. For this, Stated Preference (SP) research has been performed for three variables, including fare, travel time and the number of runs, to estimate the substitution rate of each of the three variables. Binomial Logit Model has been estimated with the obtained data. The estimation of the model has found that airline passengers of major and low-cost carriers are willing to pay approximately 7,200 KRW and 5,000 KRW, respectively, to reduce travel time by one hour. If the number of runs in one day increases, it has been estimated that the passengers are willing to pay additional fares of about 390 KRW and 30 KRW, respectively. On the other hand, the substitution rate between the number of runs and the travel time was found to be somewhat insignificant. If the construction of the Seoul-Jeju line progresses in the future, this study could be used as preliminary data for determining fares, travel time and the number of runs.

지난 2011년 일본 후쿠시마 원전 사고 이후 대내외적으로 방사능 피폭 가능성에 대한 우려가 확산되어 왔고, 국내 원전의 잦은 사고로 인해 원전 종사자들의 사고에 대한 불안감도 증폭되고 있다. 기존에는 원자력 발전소나 방폐장 주변 지역 주민들의 보상 문제가 주요 쟁점이었으나 본 연구에서는 원자력 기술 개발 관련 종사자를 대상으로 방사능 피폭 가능성에 대한 임금 프리미엄을 추정하는 데에 초점을 맞추었다. 방사능 피폭에 따른 산업재해 발생 시 근로자에게 입증 책임이 있어 적정한 보상을 받기 어렵다는 점에서 방사능 피폭에 대한 보상 문제를 민간부문에 맡길 경우 사회적으로 바람직한 결과가 도출되기 어렵다. 본 연구는 선택실험법에 의해 원자력 기술개발 종사자를 대상으로 방사능 위험에 대한 보상 수준, 방사능 노출도, 고용보장성, 회사 입지, 근무 강도가 다르게 주어질 경우 어떤 직장을 선호하는지를 설문하였다. 설문 결과 방사능 위험도가 고용 보장성이나 근무 강도, 회사 입지에 비해 더 중요한 요인임을 알 수 있었고, 추정 모형에 따라 방사능 피폭 가능성 감소에 대한 연간 지불용의액은 773~777만 원에 이르는 것으로 나타났다. 따라서 향후 정부는 원자력 기술개발 종사자가 방사능 피폭과 관련한 산업재해가 발생하는 경우 적절한 보상이 이루어질 수 있도록 법제도적 기반을 조성할 필요가 있다.
