본 논문에서는 소프트웨어의 고장수리 과정 중 완전 수리와 불완전 수리를 모두 고려하는 혼합수리 모형을 제안하려고 한다. 이를 위해 소프트웨어가 가지고 있는 전체 결함의 유형을 고치기 쉬운 결함 유형과 고치기 어려운 결함 유형으로 나누고, 고치기 쉬운 결함의 경우에서는 수리 과정 중 결함을 완전하게 고친다고 가정한다. 또한 고치기 어려운 결함 유형은 완전 또는 불완전 수리가 가능하도록 가정하며, 이러한 가정과 마코프 과정(Markov process)하에서 소프트웨어 성능 평가를 위한 측도 중에 하나인 소프트웨어 가용성(software availability)을 제시하고자 한다. In this paper, we derive an software mixed debugging model based on a Markov process, assuming that the length of time to perform the debugging is random and its distribution may depend on the fault type causing the failure. We assume that the debugging process starts as soon as a software failure occurs, and either a perfect debugging or an imperfect debugging is performed upon each fault type. One type is caused by a fault that is easily corrected and in this case, the perfect debugging process is performed. An Imperfect debugging process is performed to fix the failure caused by a fault that is difficult to correct. Distribution of the first passage time and working probability of the software system are obtained; in addition, an availability function of a software system which is the probability that the software is in working at a given time, is derived. Numerical examples are provided for illustrative purposes.

Objective: To survey the utilization status of public health and medical rehabilitation services by the persons with disabilities in community. Method: The subjects were 118 patients who were admitted to National Rehabilitation Center from January 1998 to December 2001 and agreed with home-visit. The subjects were assessed of disability level with functional scales, utilization rate of public health and medical rehabilitation services, utilization facilities, and service contents. Results: The subjects included 78 pesons with stroke, 20 persons with spinal cord injury, 9 pesons with traumatic brain injury, and 11 persons with other diseases. Only 28.0% of the low-functional group used public health and medical rehabilitation services, showing a low utilization rate than the high-functional group (43.2%). 17 out of 24 persons who used rehabilitation clinics were in the low-functional group and 9 out of 13 persons who used welfare agency were in the high-functional group (p=0.012). In two groups, most frequent utilization out of the service contents was the exercise therapy. Conclusion: The utilization rate of public health and medical rehabilitation services in communities was 32.8%. It is necessary to supply the persons with disabilities in community with the rehabilitation service for the continuum of rehabilitation.

To understand the scales of the spatial distribution and temporal duration of the subsurface chlorophyll-a maximum (SCM) observed in the Ulleung Basin of the East Sea, we analyzed physical and chemical data collected during the East Asian Seas Time-series-I (EAST-I) program. The SCM layer occurred at several observation lines from the Korea Strait to 37.9oN in the Ulleung Basin during August of 2008 and 2011. At each observation line, the SCM layer extended from the coast to about 200 km off the coast. The SCM layer was observed between 30 and 40 m depth in the Ulleung Basin as well as in the northwestern Japan Basin along 132.3oE from 38oN to 42.3oN during July 2009, and was observed around 50 m depth in the northeastern Japan Basin (135-140oE and 40-45oN) during July 2010. From these observed features, we hypothesize that the SCM layer observed in the Ulleung Basin may exist in most of the East Sea and may last for at least half-year (from the early May to late October). The nutrient supply mechanism for prolonged the SCM layer in the East Sea was not known, but it may be closely related to the horizontal advection of the nutrient rich and low oxygen waters observed in the Korea Strait between a 50 m depth to near the bottom. The prolonged development of the SCM layer in the Ulleung Basin may result in high primary production and would also be responsible for the high organic carbon content observed in the surface sediment of the region.

Objective: Comprehensive poststroke rehabilitation includes continuum of care after discharge from hospital. Day hospital is a milieu-oriented outpatient rehabilitation program that offers continuous rehabilitation service to promote psychosocial adaptation and quality of life. This study is to evaluate long-term effects of day hospital program in stroke patients. Method: Forty-eight stroke patients who received day hospital program for 2 or more months after inpatient rehabilitation program and 42 control stroke patients, who received only inpatient rehabilitation program, responded telephone interview for the study. Outcome measurement included the Korean Activities of Daily Living (K-ADL), the Korean Instrumental Activities of Daily Living (K-IADL) and the Medical Outcome Study 8-item Short Form Survey (SF-8). Results: There was no difference in many item scores of K-ADL between day hospital group and control group, but the item scores of dressing, washing face and hands were significantly higher in control group. Among the item scores of K-IADL, except managing money, most item scores of K-IADL were no significant difference between day hospital group and control group. All item scores of SF-8 were significantly higher in day hospital group than control group. Conclusion: Day hospital is an effective rehabilitation program to enhance health-related quality of life for stroke patients.
