This study attempts to examine the performances of Myun Health Workers-the frontline workers in the Korean rural health care delivery system. The time-activity approach was mainly utilized as a measuring tool. This study was undertaken in September 1976 with 35 Myun Health Workers at the Kang Wha County. The pretested time-activity approach sheets were filled out daily for one month by those Myun Health Workers themselves. Statistical means and variances of analysis were utilized for statistical method in comparing some activities and functions converged into time distribution Findings: 1. The workers's average working hours derived in this study is 8 hours and 48 minutes per day, which takes half an hour longer than normal schedule. 2. They spend 56% working hour for direct services, in other words, the main function, 22% for supportive function, and 22% for other activities, the unrelated health services. 3. Considering the total working hours of main function, out-center activity is far more than in-center services with the ratio of 70% to 30% respectively, which proves, therefore, that the main activity of the workers is home visiting. 4. It takes 20 minutes purely for home visiting and takes 14 minutes for transportation. 5. This research also indicates that such factors as characteristics of the health workers and myun influence in shaping the structures of the worker's function and activity: a. The workers whose working site is located in myun office spend 15% among total working hours in carring out official myun activities, which is incidentally unrelated to health services, while the health subcenter have no rooms for administrative jobs for myun office. b. The workers whose office is in health subcenter contribute much time in doing main function and those working in special project distribute more time in performing supportive function. c. The types of workers are another dominant factor to influence the components of worker's functions and activities. MCH workers and MPW I spend much time for manipulating main function. d. MPW II, whose function is reorganized by special project in 2 myuns shows different pattern of time distribution compared to the TB worker orFP worker in the ordinary area. MPW II distributes their time evenly in performing MCH program, T.B. Program, F.P. program and education activity, while the unipurpose workers engage in carring out only their dominant role. e. Another variables which involve the variation of the worker's activity can be illustrated with the variables like target population, size of myun and convenience for transportation, among which the latter two are remarkable factors in determining the time for out-center service.

Whilst Ecological momentary assessment (EMA) can provide important insights over time and across contexts among rotation workers whose work periods alternate with leave at home, it can also be challenging to implement in the resources and construction sectors. This review aimed to provide a summary of the methodological characteristics of EMA studies assessing health outcomes and related behaviors in rotation workers. Systematic searches in PubMed, Medline, EMBASE, CINAHL, PsycINFO, and Scopus were done to include 23 studies using EMA methods in assessing health-related outcomes and behaviors. EMA designs included daily diary: assessments once per day typically fixed at the end of day (47.8%), within day fixed interval time-based design: assessments on multiple times per day at certain times of day (17.4%) and combination of both designs (34.8%). Studies employed paper and pencil diaries (73.9%) and one or more electronic methods (60.9%): wrist-worn actigraphy device (52.2%) and online-based diaries (26.1%) for data collection. Most of the studies (91.3%) did not report prompting -EMAs by schedule alerts or compliance. Daily diary and within day fixed interval dairies designs are common, with the increasing use of electronic EMA delivery techniques. It is unclear how well participants adhere to assessment schedules, as these are inadequately reported. Researchers should report compliance-related information.

In Korea, female workforce has reached more than 40% of total working population, but the effects of work on spontaneous abortion are yet to be examined. This study as conducted to investigate the occupational effects on spontaneous abortion. Medical insurance claim data were used to examine the effects of the employment status and industry of employment on spontaneous abortion. The study population was composed of females, aged $15{\sim}44$, who were the beneficiary of medical insurance in the month of June, 1993. The working females covered by medical insurance for industrial workers, had the highest age-adjusted Spontaneous Abortion rate (SAB rate=claim frequency of spontaneous abortion/claim frequency of complication of pregnancy, childbirth and the puerperium), 6.65% whereas female dependants of medical insurance for industrial workers had the lowest age-adjusted SAB rate, 4.54%. Among industrial workers, the workers in manufacturing industry had the highest age-adjusted Spontaneous Abortion ratio(SAB ratio=claim frequency of spontaneous abortion/claim frequency of completly normal delivery), 43.2/100 whereas those in financing and service industry had age-adjusted SAB ratio, 16.2/100 and 20.5/100, respectively. The results of the study suggest the adverse effect of manufacturing Industry on reproduction. Work environments such as chemical exposures, overwork, awkard posture, and job stress should be further studied for their effects on reproductive functions of female.

Objectives: This study aims to analyze manganese (Mn) concentrations in maternal and cord bloods at delivery and to estimate the Mn exposure risk for fetuses whose mothers were occupationally exposed to Mn. Materials and Methods: Forty-six pairs of maternal and cord blood samples were collected at delivery from mothers who were occupationally unexposed to Mn. Mn concentrations of blood were analyzed by graphite furnace atomic absorption spectrometer. Mn exposure levels for fetuses of female workers were estimated by simulating two working exposure scenarios. Results: The geometric mean concentration of Mn in maternal and cord blood were $27.0(1.34){\mu}g/L$, $46.6(1.25){\mu}g/L$, respectively. Transfer ratios of Mn from maternal to cord blood were $1.81{\pm}0.62$, which indicated that the Mn concentrations in cord blood were higher than those in maternal blood. Mn concentrations in cord blood for the worse or general scenarios were estimated to $22.3-1,881{\mu}g/L$ and $1.59-308{\mu}g/L$, respectively. The probabilities of exceeding $74{\mu}g/L$, which was adopted as a reference level reported in a previous study, were 95% and 44% for the two scenarios, respectively. Conclusions: Comparable levels of Mn exposure in maternal or cord blood to those in this study have shown various health effects in previous studies. This suggests that Mn exposure levels in mothers and fetuese in Korea need to be monitored and managed. In addition, female workers who are occupationally exposed to Mn should be protected from the exposure since their fetuses can be exposed to Mn at risky levels during their pregnancy.

다중 지역으로 구성된 이동 에이전트 컴퓨팅 환경에서 공간적 복제 기반 기법(SRBA: Spatial Replication-Based Approach)은 에이전트의 고장발생 시에도 그 에이전트의 수행이 대기 없이 계속적으로 진행될 수 있도록 하기 때문에, 대표적인 이동 에이전트 결함 포용 기법으로 사용될 수 있다. 그러나 이 기법을 실제의 이동 에이전트 기반 컴퓨팅 시스템에 적용하는데 있어서, 단계별로 복제된 이동 에이전트들에 대한 위치추적 및 관리비용을 최소화시키는 것이 필수적이다. 본 논문에서는 이러한 문제점을 해결하는 새로운 이동 에이전트 위치 관리 프로토콜인 SRLM(Location Management protocol for Spatial Replication)을 제안한다. 제안된 프로토콜은 단계군 내의 복제된 이동 에이전트들 중 대표 작업자만이 자신의 지역서버에게 위치등록하게 함으로써 기존 프로토콜에 비해 위치갱신 및 메시지 전달 비용을 매우 줄인다. 또한, 이 프로토콜은 한 단계 군에서의 대표 작업자 결함 발생시 새로운 대표 작업자의 선출로 인한 위치 관리 문제를 해결한다.
