We report the electrocution of Korean native cattle by a fallen electric wire, which caused the death of thirteen animals. The owner of the cattle felt an electric shock on touching the steel pen and found a fallen 220-V wire on the roof of the barn; additionally, the roof was singed. Clinically, the animals developed spasm, difficulty breathing, and excessive salivation. Histopathologically, many visceral organs revealed severe congestion or hemorrhage, which is consistent with previous reports. This study revealed that the proper installation of electric wires on farms is essential to prevent economic loss by electrocution.

The extranodal nasal NK/T-cell lymphoma was formerly known as lethal midline granuloma due to its most common clinical pattern like a destructive midline facial tumor. It often spread to other extranodal sites, such as skin, soft tissue, testis, upper respiratory tract, and gastrointestinal tract etc. For this reason, the term of extranodal NK/T-cell lymphoma, nasal type is preferred. Its disease entity may have a prominent admixture of inflammatory cells and necrotic tissues, further causing difficulty in diagnosis. A 44-year-old man was visited to our clinic with complaints of dysphagia and odynophagia during six months. He underwent three times punch biopsies and then, two times incisional biopsies. Finally, He was diagnosed as extranodal NK/T-cell lymphoma, nasal type involving oropharynx and supraglottis. We report an extremely rare case of extranodal NK/T-cell lymphoma, nasal type occurred in oropharynx and supraglottis with a brief review of literature.

본 연구는 사회복지분야에서는 그다지 시도되지 않았던 원가분석 방법과 특성을 검토하고, 장애인복지관 20개소를 대상으로 실제 장애인복지관서비스의 원가분석 결과를 사례로 제시하여 사회복지서비스 원가분석에 대한 함의를 제공하는 것을 목적으로 한다. 본 연구는 2002년 12월 기준 전국 장애인복지관 95개소 중 20개소를 최종적으로 분석하였다. 분석목적을 위해 해당 복지관의 2002년 세입 세출결산서와 연간사업실적보고서를 사용하였으며, 분석대상 복지관 실무자를 대상으로 중요도, 난이도, 업무비중에 근거하여 서비스별 가중치 조사를 실시하여 반영하였다. 원가분석방법으로는 '활동기준원가분석'(activity-based costing)이 아닌 '전통적 원가분석방법'(traditional cost accounting)을 사용하였다. 분석결과 2002년 기준 장애인복지관의 세출평균은 12억 6천 여 만원이며 이 가운데 65.8%는 인건비로, 13.2%는 재활사업비로 집행된 것으로 파악되었다. 서비스원가사례로 재가복지생활지원서비스의 경우 60분 기준 26,922원으로 직업상담직능평가의 경우 120분 기준 143,355원으로 계산되었다. 이러한 원가에는 낮은 임금수준 및 부동산비용 등이 반영되지 않아 실제 시장가격은 훨씬 높을 것으로 추정된다. 분석 결과는 추후 서비스의 중단, 축소, 확대, 자원배분 등 프로그램과 관련한 의사결정에 더 유용하게 활용될 수 있을 것이다.

Purpose: This study aimed to determine the correlation between job performance difficulties and job satisfaction that novice health teachers experienced in a new school environment, and provide the basic data necessary for policy development. Methods: Data were collected from 196 novice health teachers without in-service training program for the qualification of 1st grade and with less than four years of work experience in Korea. The self-report questionnaire consisted of general characteristics, perception of difficulties in job performance, and job satisfaction. The data were analyzed using the x² test, t-test, ANOVA, and Pearson's correlation coefficient. Results: Novice health teachers had the most difficulty in health education during their job performance, whereas teachers without hospital clinical experience encountered difficulties in health management. Those with less than two years of teaching experience or no experience of being contract health teachers had higher job performance difficulties. The results revealed that the lack of experience in performance at a school site had a considerable influence on the difficulty in job performance. In terms of job satisfaction, novice health teachers had the highest satisfaction with status recognition and the lowest satisfaction with their tasks in charge. Additionally, as the difficulty in job performance increased, job satisfaction decreased. Conclusion: The study results indicated the need for training to provide novice health teachers with sufficient experience in job performance before being placed in a school. The provision of support to respond to difficulties in job performance will improve job satisfaction and contribute not only to the development of novice health teachers, but also to the improvement of the quality of school health.

Objectives : The objective of this report is to identify the utilization of hospital school service during hospitalization among patients in their childhood and adolescence with psychiatric disorders. Methods : We retrospectively reviewed the medical record of child and adolescent psychiatric who were hospitalized during March 2009 through October 2012. We compared the one-year successful schooling and outpatient follow up rate between users and nonusers of the inpatient hospital school service. The hospital schooling experiences of the users were investigated upon follow-up visits to the outpatient clinic. Results : Sixty-three students received hospital school service during hospitalization among total 122 child and adolescent inpatients. Hospital school participants showed a significantly higher school reentry rate (61.9%) than non-participants (40.7%). However, there was no difference on follow up rate between the two groups. More than 60% of the 22 interviewed participants expressed an above-average level of satisfaction about hospital school service. Conclusion : Many patients with mental illness experience difficulty in receiving school education during treatment. That induces deterioration in disease, academic failure, poor social skills, low self-esteem, economic difficulties, and future job opportunities. The results of this study emphasize the importance of hospital school service and offer useful guidance for hospital school operation.

The purpose of this study is to discover and develop any implications which may arise in relation to science teachers' professional growth and development by investigating the difficulties experienced by elementary school teachers in science classes. 196 elementary school teachers were requested to write an anecdotal report regarding their science lessons. 30 science teachers in middle school also answered the same questionnaire. By means of inductive categorical analyzing, the difficulties were grouped into several categories. The results were as follows: (1) The difficulties elementary teachers experience in their science lessons fall into three categories; 'professional science knowledge(9.8%)', 'science laboratory activities(78.3%)', 'teaching methodology(11.2%)'. (2) Science teachers in middle school experienced similar difficulties. However, distribution differed from that of elementary school teachers; 'professional science knowledge(39.0%)', 'science laboratory activities(35.6%)', 'teaching methodology(27.1%)'. (3) The causes of these difficulties were identified as follows; a lack of time to prepare for science classes, insufficient substantial pre-service teacher education, and a lack of adaptive support to elementary school teachers.

KSNPs(Korea Standard Nuclear Power Plant) have been applied the break exclusion criteria to the high energy lines passing through containment penetration area to ensure that piping failures would not cause the loss of containment isolation function, and to reduce the resulting dynamic effects. Systems with the criteria are the Main Steam system, Feed Water system, Steam Generator Blowdown system, and Chemical & Volume Control system. In accordance with FSAR(Final Safety Analysis Report), a 100% volumetric examination by augmented in-service inspection of all pipe welds appled the break exclusion criteria is required for the break exclusion application piping. However, it is difficult to fully satisfy the requirements of inspection because 12", 8" and 6" weldolet weldments of Main Steam pipe line have complex structural shapes. To resolve the difficulty on the application of conventional UT(Ultrasonic Testing) technique, realistic mock-ups and UT calibration blocks were made. Simulations of conventional UT were performed utilizing CIVA, a commercial NDE(Nondestructive Examination) simulation software. Phased array UT experiments were performed through mock-up including artificial notch type flaws. A phased array UT technique is finally developed to improve the reliability of ultrasonic test at main steam line pipe to 12", 8" and 6" branch connection weld.

Low birth rate problem in Korea has been mainly derived from the increasing number of female employment and the change of consciousness of female. According to the recent report, some other causes of low birth rate are from the difficulty of using childcare facilities with quality services and the relative lack of quantities of the facilities. The basic principle of childcare includes protection, education, nutrition, safety, service to parents, and correlation with community. Childcare has been deemed to be the social system even to guarantee the parents' right of work. Even though a lot of progress has been made in childcare facilities by changes for a long period of time, the research on the actual condition shows that there are relatively little changes of the space organization of the childcare facilities reflecting characteristics of community and developmental characteristics of infants and children. Now a days it has been appeared as a social problem that childcare has to be needed as a part of systematic education program for such an important infant era.
