The purpose of this study is to present an actual example for procedures for developing a PBL package based on philosophical backgrounds derived from Problem-based learning. To perform a systemic study on the operations of an intergrated curricula under multidisciplines, a research team made up of several professors with different academic backgrounds was formed. Among the four situations for the patients with perception-adjustment disorder, especially a procedure for the development of PBL package which can be used in the emergency room situation has been proposed. The little(2000)'s PBL package model has been applied for this study. Tha package includes course objectives, learning objectives, concept map, situation scenario, tutor guide, and evaluation method. It is believed that learning objectives achievement procedures designed as a part of a problem-based learning package development procedures for the nursing of patients with perception-adjustment can be achieved at the same level as the learning objectives for the science of nursing founded by the Korean Nurses Association.

As software development and maintenance cost increase quickly, information systems managers are more concerned about how to effectively manage software cost. To estimate the software development cost, most public institutes of Korea use the software cost estimation standard established by the government. Unfortunately, the accuracy of the estimation derived from the standard has not been satisfactory in spite of repetitive modifications made to improve it. One of the major reasons for the inaccuracy is that the standard has too small a number of cost adjustment factors to reflect the various characteristics of a software development project. To remedy this problem, we propose new cost adjustment factors which can be incorporated into the standard and are important to enhance the estimation accuracy, based on the analysis of several well-known software estimation models. Furthermore, by applying the proposed model to real world software projects, we show that the proposed model can produce more accurate estimates than the current standard.

본 논문에서는 IEEE 802.16 OFDMA 시스템에서 QoS를 제공해 주기 위해서 표준에서 정의해 놓은 서비스 클래스 별 대역폭 할당 기법 중에서 UGS 클래스의 대역폭 할당 기법에서의 문제점을 지적하고 이를 해결하기 위한 알고리즘을 제시한다. 802.16 시스템에서는 다섯 가지 트래픽 클래스를 정의하고 이 중에서 UGS 클래스의 서비스 우선 순위를 가장 높게 처리하고 있다. 하지만, 기존의 UGS 클래스를 위한 대역폭 할당 방식에서는 다수개의 UGS 클래스가 존재할 때의 대역폭 할당 주기가 겹치는 문제에 대한 고려를 하고 있지 않다. 이로 인해서 오히려 UGS 클래스의 QoS 서비스를 제공해 줄 수 없는 상황이 발생하게 된다. 본 논문에서는 이런 문제점의 발생을 성능측정을 통해서 보여 주고 이를 해결하기 위한 알고리즘을 제시한다. 또한, 성능 비교를 통해서 제안하는 알고리즘 적용 시에 성능 향상이 있음을 보여 주고자 한다. 본 알고리즘의 적용을 통해서 실제 시스템 적용 시에 발생할 수 있는 문제점을 해결함으로써 보다 안정적인 QoS 서비스를 제공할 수 있는 802.16 시스템이 되리라 기대한다.

본 연구는 청소년의 학업소진과 학교생활적응 및 스트레스 대처 관계를 살펴보고 학업소진과 학교생활적응의 관계에서 스트레스 대처 방식이 매개효과로 작용하는지를 검증하고자 실시하였다. 경기도 소재 17개 중학교에 재학 중인 1232명의 학생들을 대상으로 설문조사를 실시하였으며, 수집된 자료는 SPSS 21.0 프로그램을 이용하여 분석하였다. 조사대상 중학생들은 학업소진의 하위요인 중 공부에 대한 반감과 냉담 등의 심리적 소진증상을 많이 경험하고 있었다. 학업소진은 학교생활적응 및 스트레스 대처 중 적극적 대처인 문제지향과 사회적지지 추구와는 부적상관관계를, 학교생활적응과 스트레스대처는 정적상관관계를 보였다. 학교생활적응에 대한 학업소진과 스트레스대처 방식의 상대적 영향력을 살펴본 결과, 스트레스 대처 중 문제지향과 사회적지지 추구 대처가 학교생활적응에 직접적으로 긍정적인 영향을 미치는 주요 요인이라는 것을 알 수 있었으며 특히, 스트레스 대처 중 문제지향 및 사회적지지 추구 대처는 학업소진과 학교생활적응간의 관계에서 부분적 매개 감소효과가 있음을 확인하였다. 따라서 학업소진을 경감시켜 만족한 학교생활을 영위하기 위해서는 학업스트레스 등에 적극적 대처 행동을 실천 할 수 있도록 능동적 대처능력 향상 프로그램 개발 및 도입 등의 체계적인 교육 및 지원방안이 모색되어야 할 것이다.

The main purpose of this study was to identify the relationship of self efficacy and social support to the psychosocial adjustment in people with epilepsy. Data were collected from October 1 to October 15, 1999 from 101 people with epilepsy who were being treated regularly at one of the university hospitals located in Seoul. The research instruments were a questionnaire to gather demographic and disease-specific data, the Epilepsy Psycho- Social Effects Scale developed by Chaplin et al(1990), the Epilepsy Self Efficacy Scale developed by DiIorio et al(1992a) and translated by Park(1999), the Norbeck Social Support Questionnaire developed by Norbeck et al(1981) and translated by Oh(1985). Data were analyzed using the SPSS program. The results are as follow : 1. Of the 14 psychosocial adjustment areas, 75 of 101 subjects experienced problems in ten or more areas and 28 in all 14 areas. The severity of the psychosocial adjustment problem was moderate or more in six areas. 2. The score for self efficacy was an average of 1103.86 out of a possible 1800, for social support 117.57 for total functional out of a possible 720, and 48.21 for total network out of a possible 264. There were an average of five people on the network. The main network people were parents, brothers and sisters, spouse, friends. 3. Of the 14 psychosocial adjustment areas, six areas correlated with self efficacy and 'problems with taking medication' area had a negative correlation with social support. In conclusion, people with epilepsy have various problems in psychosocial adjustment. Nursing interventions using self efficacy should be developed to improve psychosocial adjustment in people with epilepsy. Also, instruments and interventions for regimen-specific supports which are suitable for epilepsy should be developed.

By means of flexible forming processes in sheet metal manufacturing it is possible to produce parts of complex geometry within short manufacturing time. These procedures are suitable especially for prototyping or adjustment of deformation. Here formative procedures like laser forming are increasingly important, because they make the large-scale-like production of the prototypes with the required materials possible. High accuracy and reproducibility of the products is the precondition of the production. Due to the lack of a forming tool, complex geometries can hardly be manufactured within tolerances. To overcome this problem an automatic closed loop control system for the adjustment of deformations has been developed. An important element of the closed loop control system is the definition of a suitable irradiation strategy for laser forming. For the determination of the irradiation strategy a lot of influences must be taken into consideration from the field of material, geometry and laser. In this paper the improved closed loop control system and the development of an irradiation strategy for 4 mm deep buckles in an ALMgSi1 sheet will be represented. This system can be used e.g. in the automated adjustment of hail damage in car bodies or deformation by heat treatment.

This paper investigates optimum air-gap flux distribution with third harmonic rotor flux orientation adjustment for five-phase induction motor. The technique of objective is to generate a nearly rectangular air-gap flux, and it improves iron utilization under variation loading conditions. The proportional relations between third harmonic and fundamental plane currents is usually adopted in the conventional method. However, misalignment between fundamental and third harmonic component occurs with variation loading. The iron of stator teeth is saturated due to this misalignment. This problem is solved by third harmonic rotor flux orientation adjustment simultaneously, and direction and amplitude are changed with mechanical load variation. The proposed method ensures that the air-gap flux density is near rectangular for a maximum value from no load to rated load. It is confirmed that the proposed method guarantees complete both planes decoupling with third harmonic flux orientation adjustment. The effectiveness of the proposed technique is validated experimentally.
