This study was designed to identify the relationship of perceived self-efficacy and sick-role behavioral compliance in diabetic children. The forty-two diabetic children participating in this study were selected from outpatients. he period of data collection was August 8 to December 9, 1994. Collected data were analyzed by means of chi-square test, t-test, Pearson correlation using SPSS/P $C^+. The result are summarized as follows : 1. The mean score of perceived self-efficacy was 3. 21 that of sick-role behavioral compliance 3.17. 2. Perceived self-efficacy and sick-role behavioral compliance had a positive correlation which was statistically significant（r=0.77, p＜0.001）. 3. There were statistically significant difference in perceived self-efficacy according to age（p＜0. 01） and acknowledgment of prescribed calories in the diabetic diet（p＜0.001）. 4. There were statistically significant difference in sick-role behavioral compliance according to age （p＜0.01） and acknowledgment of prescribed calories in the diabetic diet （p＜0.001）. These results suggest that perceived self-efficacy is an important variable in the compliance of diabetic children. Nursing intervention needs to be directed at promoting perceived self-efficacy to maintain sickrole behavioral compliance for diabetic children. Therefore programs of nursing intervention should be revised in order to promote perceived self-efficacy in diabetic children.en.

This study is designed to find women's makeup color preferences according to their pursuing clothing image and clothing behavior. Subjects were 515 women. from 18 years to 40 years old, who are interested in color makeup and use various products. The SPSS statistical program was used for analyzing the demonstrative results of questionnaire survey. The results of this study are as follows : 1. According to color makeup preference by the pursuing image in clothing. those groups who want to have conservative and neat image and who prefer feminine and intellectual image showed the preference of brown lipsticks and eye-shadows, while groups who want to have vivid image preferred orange lipsticks and pink eye-shadows. 2. In the case of casuals, all groups preferred pink eye-shadows and lipsticks. While those groups who want to have intellectual image preferred brown lines after pint groups who want to have sexy and vivid image preferred orange and red lipsticks and blue and green eye- shadows. 3. In preference comparison of color makeup by clothing behavior, those groups who attach practicality, symbol for social status. and social acknowledgment preferred red and brown lipsticks, and brown eye-shadows. 4. In the case of wearing casuals, all groups liked pink eye-shadows and lipsticks the best. whereas the group who want to have social acknowledgment Preferred beige lipsticks and brown eye-shadows.

This paper investigates schemes to improve TCP performance in multipath forwarding networks. In multipath routing, packets to the same destination are sent to multiple next-hops in either packet-level or flow-level forwarding mode. Effective bandwidth is increased since we can utilize unused capacity of multiple paths to the destination. In packet-level multipath forwarding networks, TCP performance may not be enhanced due to frequent out-of-order segment arrivals at the receiver because of different delays among paths. To overcome this problem, we propose simple TCP modifications. At the sender, the fast retransmission threshold is adjusted taking the number of paths into consideration. At the receiver, the delayed acknowledgment scheme is modified such that an acknowledgment for an out-of-order segment arrival is delayed in the same way for the in-order one. The number of unnecessary retransmissions and congestion window reductions is diminished, which is verified by extensive simulations. In flow-level multipath forwarding networks, hashing is used at routers to select outgoing link of a packet. Here, we show by simulations that TCP performance is increased in proportion to the number of paths regardless of delay differences.

The purpose of this study was to examine the effect of three types of praise activities on school adjustment of sixth graders. We assume that there are three types of praises; Verbal reinforcement, Encouragement, and Social acknowledgment. The study is based on pretest-posttest experimental design. The subjects of this study were 55 six- grade students who enrolled to two classes of an elementary school located in Busan. One class (26 students) was an experimental group and the other class(29 students) was a control group. Three types of praise activities were applied to the experimental group for 11 weeks. The activities were composed of classroom activities for understanding of the concept of praise, online activities, praise card activities for practicing three types of praises. School Adjustment Scale developed by Lee Young-Sun(1997) was administrated to all the subjects as the pre and post-test. To verify the effects of the experiment, ANCOVA was conducted. The treatment group showed a statistically significant increase in school adjustment, but the control group that received a neutral intervention did not.

Judgment of cerebral and cardiovascular diseases arising out of duty follows the legal judgment method for the purpose of investigation of medical causes based on the Industrial Accident Compensation Insurance Act, with the characteristics of the occurrence as personal factors etc. act as risk factors while work-related ones as triggers, in the case of disease due to occupational cases, as whether it arose out of duty must be judged including even the individual's personal risk factors, there are limitations securing fairness even with existing laws, regulations and guidelines. This study was carried out to suggest basic data for the preparation of standardized guidances for diseases arising out of duty by reviewing the standards for the acknowledgment of cerebral and cardiovascular diseases due to occupational cases, and it has a significance in that it suggests target diseases that may be judged as cerebral and cardiovascular diseases, legal criteria for the acknowledgment and standards for the judgment of cerebral and cardiovascular diseases arising out of duty.

This article investigates the problem of opportunistic spectrum access in dynamic environment, in which the signal-to-noise ratio (SNR) is time-varying. Different from existing work on continuous feedback, we consider more practical scenarios in which the transmitter receives an Acknowledgment (ACK) if the received SNR is larger than the required threshold, and otherwise a Non-Acknowledgment (NACK). That is, the feedback is discrete. Several applications with different threshold values are also considered in this work. The channel selection problem is formulated as a non-cooperative game, and subsequently it is proved to be a potential game, which has at least one pure strategy Nash equilibrium. Following this, a multi-agent Q-learning algorithm is proposed to converge to Nash equilibria of the game. Furthermore, opportunistic spectrum access with multiple discrete feedbacks is also investigated. Finally, the simulation results verify that the proposed multi-agent Q-learning algorithm is applicable to both situations with binary feedback and multiple discrete feedbacks.

과거의 자동차 인테리어 디자인은 스타일링이나 인간공학적 측면을 주로 배려하여 디자인되어 왔다. 그러나 시간의 흐름에 따른 사용자의 가치 및 요구(needs)의 다양화, 흑은 관련 기술의 발전에 따라 "주행" 중 "제어"해야하는 많은 기능들이 추가됨에 따라 이러한 다양한 조작 대상들을 동시에 조작하거나 조작하기 위한 학습이 점점 더 어려워지고 있는 실태이다. (중략)
