The purpose of this study was to examine the influence of the self-control of dental hygiene students on their stress and stress-coping style. The subjects in this study were dental hygiene students who were selected by convenience sampling from three different colleges. After data were gathered, the answer sheets from 561 respondents were analyzed. The findings of the study were as follows: 1. Concerning the level of self-control, the dental hygiene students got a mean of 3.22. As to self-control by grade, the juniors got the highest scores of 3.27 (p<0.05), and those who were under heavier stress were poorer at self-control (p<0.05). 2. In regard to stress-coping style, they got a mean of 3.28 and 3.34 in active coping and passive coping respectively. Passive coping was more prevailing, and the students whose economic status was higher made more use of active coping styles (p<0.001). There were statistically significant differences in active coping styles according to stress level (p<0.01) and the effect of stress on health (p<0.05). 3. Better self-control led to more frequent use of active coping styles. The above-mentioned findings imply that self-control is one of factors to affect stress coping. Therefore the development of counseling programs is required to step up the improvement of self-control.

Objectives: Cognitive-behavioral scientists have long been interested in how a pain patient's cognition such as locus of control relates to coping and adjustment. The present study examined the relationship of locus of control orientation to pain coping strategies, psychological distress and perceived pain intensity of patients with pain. Methods : Subjects were 96 patients with pain who visited pain clinic. All patients were administered the Multidimensional Health Locus of Control Scales, the Minnesota Multiphasic Personality Inventory, the Coping Strategies Questionnaire, and rating for perceived pain intensity, distress, and duration. Results : Correlational analysis revealed that patients who viewed outcomes as controlled by internality tended to have better ability to control and decrease pain. Also they tended to be less depressed and anxious. Regression analysis indicated that patients having a internal locus of control were more likely to use coping self-statement and reinterpreting pain sensation. Powerful others and chance locus of control orientation were predicted reliance on catastrophizing. Conclusion : The clinical implication of the present study is that cognitive factors of patients with pain such as locus of control influence emotional distress and coping. this study show that these factors should be applied to cognitive behavioral therapeutic intervention.

하며 최적의 합리적인 경영을 할 수 있도록 생산환경을 뒷받침할 수 있어야 한다. 이를 위해서는 생산시스템 전반에 걸친 정보 및 통신 기술의 중요성이 다른 어느것 보다도 더욱 더 강조되며, 그리고 중요한 역할을 담당해 나가고 있다. 본 연구에서는 이러한 최근의 환경을 나타낼 수 있는 제조환경에서 중추적인 역할을 담당하는 생산통제시스템에 사용되고있는 정보기술에 관하여 기존의 생산통제방식(납기일결정방식, 생산입력통제방식, 우선순위결정방식)에서 사용되고있는 정보의 내용을 분석하여 생산환경의 어느 부분의 어떤 정보가 생산통제시스템에서 중요한 역할을 담당할 수 있는지를 연구하고, 생산시스템 각 부분에서 반드시 고려되어야 하는 정보의 내용을 제시하고자 한다.

The access control techniques, which can control unauthorized members to access to multicast service, have not been studied very often while there are a lot of on-going study on secure multicast architecture, multicast key distribution and sender authentication scheme have been studied. Multi level access control scheme in multicast can be used in a remote secure conference or to provide graduated multimedia services to each customers. In fact, multicast network has its own virtual networks according to different security levels. However, Early schemes are not effective when it protects unauthorized access in multi-access network environment. Furthermore this scheme does not provide us with hierarchical access control mechanism. This paper, therefore, proposes hierarchical access control scheme to provide the effectiveness in network layer by security level comparison. And we also suggests hierarchical key distribution scheme for multi level access control in application layer and effective hierarchical key renewal scheme in dynamic multicast environment which is easy to join and leaving the multicast group.

본 연구는 온라인 대학 강의에서 수강생들의 강의관련 질문과 답변 내용을 주간 단위로 모아서 수강생들에게 추가로 공지하는 상호작용이 학업성과와 강의만족도에 어떠한 영향을 주는가를 파악하는데 목적을 두었다. 이를 위해 실험법 중 통제집단사후측정 비교설계 방식에 따라 진행하였다. 각 집단은 한 분반이 200명 단위로 분반되는 대형수강과목을 1개 선정하여 600명을 3개 분반에 무선할당 하여 각각 실험집단1, 실험집단2, 통제집단으로 하였다. 실험집단1에게는 이메일로 내용을 전달하고, 실험집단2에게는 과목공지게시판을 통해서 내용을 전달하며, 통제집단에게는 아무런 처치를 하지 않았다. 종속변수는 해당 과목에 대한 수강생들의 학업성적과 강의만족도이었다. 그 결과, 통제집단보다 실험집단1과 실험집단2에서 학업성적이 유의미하게 높게 나타났다. 그리고 실험집단 중에서는 1집단이 2집단보다 유의미하게 학업성적은 높았는데, 강의만족도는 유의미한 차이가 없었다. 이것은 강의관련 질문에 대해 교수자가 수강생들에게 적극적인 상호작용을 많이 하는 것이 긍정적인 효과를 낳을 수 있는데, 상호작용의 방식은 과목공지게시판보다는 학생에게 보다 편리한 이메일 전달방식이 더 효과적임을 실증적으로 보여주는 것이다.

멀티캐스트 기술은 다자간 비디오회의, 대화형 원격 강의, 소프트웨어 배포, 인터넷 게임 등 특정 사용자 그룹에게만 전송하는 효율적인 통신기술이다. 그러나, 멀티캐스트의 개방적 특성상, 언제 어디서나 임의의 그룹멤버가 메시지를 보낼 수 있다. 따라서 부적절한 데이터의 수신으로부터 그룹 멤버들을 보호하고 다양한 DOS 공격으로부터 멀티캐스트 트리를 보호하기 위해 송신자 접근통제를 수행하는 것이 중요하나 소스기반과 단일지점 또는 랑데부 지점에서 인가되거나 인증되는 연구가 진행되어 왔다. 본 논문에서는 접근권한에 따라 전송 메시지가 라우터의 임의의 지점에서 사진에 통제될 수 있는 양방향 멀티캐스트 트리에 대한 다단계 송신자 접근통제 메커니즘을 제시한다 다음으로 제시한 방식과 기존 전송 방식간의 메시지 전송 효율성 측면을 실험을 통하여 분석한다. 제안 방식이 라우터상에서 접근권한의 비교를 통하여 메시지를 사전에 걸러냄으로써 상대적으로 작은 메시지 전달 오버헤드를 갖는 것을 확인하였다.

The purpose of this study was to determine the status using the smartphone targeting millitary lesson students, and self-control and coping investigate the influence on smartphone addiction level. The results were also analyzed were to affect this age of smartphones college hours per day using a smartphone to an hour or more self-important 95.3% in individual daily levels of smartphone addiction to sex differences. Smartphone addiction levels showed a higher female than male students, the higher the self-control and self-control over the smartphone results of analyzing the relationship between addiction smartphone addiction has been analyzed to be lowered. In addition, even between coping and smartphone addiction emerged as significant results. In conclusion, the self-control necessary for use in smartphones and use time period, and this was demonstrated that coping problem-oriented coping strategies are required. Were discussing the implications of the study on the basis of these findings, we discuss the future research challenges and limitations.

Under the physical records management system, both the records and users could be controlled and secured by closing the door of Archives or using permitted records which is used only approved users. According to the electronic records management system and the concept of service on the basis of users, we have to give up the classical manner. As an alternative, we have to consider the electronic access control system. To accomplish this purpose, functional requirements of ERMS that is issued by UK, EU, U.S and Australia must be compared and analyzed. On the basis of U.K ERMS which is more detailed, 'common access control functional requirements' are arranged. As the access control functional requirements is applied in the records classification scheme, we could find out how the access control is executed in ERMS.

The purpose of the present study was to test the relationship between perceived parenting styles and emotional problems among adolescents, and to obtain basic informations in terms of preventing and reducing the emotional problems. Based on literature review, a structural equation model to explain the causal relationships between democratic parenting and emotional problems, and between controlling parenting and emotional problems respectively. This study analyzed the 6^th and 7^th data from Korean Children and Youth Panel Survey. The major results of the study are as follows. First, democratic parenting had a negative relationship with emotional problems. Second, controlling parenting had a positive relationship with emotional problems. Third, according to the gender and level of subjective health, there were significant differences in perceived parenting styles and emotional problems. Finally, in terms of improving parenting skills and reducing emotional problems, implications of the research findings and suggestions were discussed.
