본 실험에서는 CLA와 ω-3 PUFA의 단일 및 혼합급여가 어린 병아리의 지질대사에 미치는 영향을 조사하기 위한 목적으로 수행하였다. 옥수수와 대두박 위주의 기초사료에 CLA 및 ω-3 PUFA의 급여가 간 및 혈중 지질분획의 농도에 변화를 미치지 못했으며, 콜레스테롤 생합성 경로에도 영향이 없었음이 시사되었다. 그러나 HDL-C와 HDL-C/total-C의 비율을 증가시킴으로써 항동맥경화 효과가 있음이 확인되었다. This study was conducted to investigate the dietary effects of single or combination feeding of conjugated linoleic acid (CLA) and ω-3 fatty acids on lipid metabolism in young chicks. Chicks were fed one of five diets containing 4% tallow, 2% tallow-2% CLA, 4% linseed oil, 2% linseed oil-2% CLA or 4% CLA for 4wks. There were no significant differences in growth performances and the levels of GOT and GPT. The contents of various lipid fractions in liver and serum were not affected by the dietary treatm ent. The serum HDL-C and HDL-C/total-C w ere significantly low er in 4% tallow group than those of other groups. The expression of HMG-CoA reductase mRNA was not influenced bt dietary treatment.

With the expansion and reinforcement of the administrative function now underway, the quality and competence of government employees is becoming increasingly important. Faced by a rapidly modernizing society, local governments are realizing the urgent need to upgrade the quality and reliability of their administrative service. They know this can be achieved by enhancing the quality and competency of their employees By doing this they can meet the need of residents for a more diverse and higher quality administrative service. Against this backdrop, this study is designed to indentify the problems to the development of the local government employees' managerial competency with special emphasis on their in-service traning. To this end, the study has attempted to evaluate the managerial capacity of local government employees as well as to shed light on the current status of training institutes for local government employees and their attitude toward the in-service training offered by the institutes. The probvlems identified in this study and the recommended measures for their resolution are as follows : 1) The central government needs to pay greater attention to the training of local government employees and offer greater assistance for the more effective implementation of the programs. 2) The educational system should be revised. 3) The working conditions for instructors at those training institutes should be improved. 4) The syllabus of the training programs for middle-ranking officials should be improved. 5) Local government employees should have equal educational opportunity. 6) Local government employees should change their perception and attitude toward in-service training. In conclusion, continued training was found to be essential to the development of local government employees' managerial competency. To prevent the further deterioration of the quality of local government for administrative service, the anthorities concerned should take specific steps to resolve the aforsaid problems, focusing their efforts at first on those problems to which there are obvious, pratical solutions. Greater administrative support offered by the authorities concerned will be crucial to the success of the educational programs. These efforts alone will upgrade the contents and methodology of in-service training for local government employees and thus ensure the development of local administration and the nation as a whole.

본 논문은 영구자석 기기의 무부하 자계 예측을 위한 해석적 접근에 대해 다루었다. 먼저, 자기벡터자위를 기반으로 영구자석기기의 무부하 자계 예측을 위한 일반적인 지배방정식을 도출하였고, 직선형 영구자석 기기와 회전형 영구자석 기기의 기하학적인 구조를 적용하여, 직각좌표계와 원통 좌표계에서의 자기벡터자위의 일반 해를 도출하였다. 특히, 회전형 영구자석기기의 경우반경 방향 자속 영구자석기기와 축 방향 자속 영구자석기기를 구분하여 각각에 적합한 일반 해를 도출하였다. 도출된 자기벡터자위의 일반 해와 정의를 이용하여, 각 영구자석기기의 법선과 접선 성분의 자속밀도를 예측하였으며, 기하학적인 구조가 고려된경계조건들을 적용하여, 최종적인 자속밀도 식을 도출하였다. 해석적 방법으로 얻어진 결과는 유한요소해석결과와 비교하여, 그타당성을 입증하였다. 본 논문에서 제시된 해석적 방법은 전기자 코일에 의한 자계 예측에 동일하게 적용 가능하며, 이러한 자계들로부터 영구자석기기의 주요 성능 인자(토크, 기전력, 인덕턴스, 코깅토크 등)를 빠르고 비교적 정확하게 예측할 수 있어, 영구자석기기의 해석 및 설계 관련 연구에 응용이 가능할 것으로 사료된다.

Objective: This study aimed to assess whether the conventional treatments administered in the emergency department (ED) for hypertensive urgencies (observed or peroral [PO]-controlled) in severe high blood pressure (BP) patients with epistaxis increase the incidence of epistaxis recurrence and the mortality rate as compared to immediate BP control using intravenous (IV) antihypertensive medication Methods: A retrospective study over 7 years was conducted at the ED of a tertiary university hospital. Among adult patients with spontaneous epistaxis, subjects with severe high BP (systolic BP ≥180 mmHg or diastolic BP ≥120 mmHg) were included in the study. Participants were divided into three groups determined by the methods used to control BP: non-controlled, PO-controlled, and IV-controlled groups. The incidence of epistaxis recurrence and mortality rate within 6 months were compared. Results: Among the 380 patients enrolled, 238 were discharged from the ED without any pharmacological antihypertensive treatment (non-controlled group), 83 received PO antihypertensive medication (PO-controlled group), and 59 received IV antihypertensive medication (IV-controlled group). Of these, 29 (12.2%), nine (10.8%), and seven (11.9%) patients from the non-controlled, PO-controlled, and IV-controlled groups, respectively, experienced epistaxis recurrence within 24 hours, which was statistically not different among the three groups (P=0.948). The 6-month mortality rates were determined to be 0.8%, 2.4%, and 3.4% in the non-controlled, PO-controlled, and IV-controlled groups, respectively. The difference was also not significant among the groups (P=0.294). Conclusion: The conventional treatments of hypertensive urgencies (observed or PO-controlled) in patients with severe high BP with epistaxis in the ED did not increase the incidence of epistaxis recurrence and short-term mortality rate when compared to immediate BP control using IV antihypertensive medication.
