본 논문에서는 모바일 노드들의 움직임이 심한 MANET 환경에서의 데이터의 전송을 안정적이고 신뢰성있게 하기 위한 방법을 제시하고자 한다. 우회경로가 적은 경우보다 우회경로가 많이 확보되었을 때 상호간의 통신이 더욱 안정적이나, 기존 연구에서는 이러한 고려가 충분히 되어있지 않고, 경로 설정 당시 알고리즘에 의해 최적화된 경로라고 판단된 경로만 기억해 놓기때문에 경로 손실이 되었을 때에 우회경로가 존재 함에도 불구하고 패킷 전송을 실패하게 된다. 본 논문에서는 확률에 기반한 안정도를 측정하고 MANET 환경에서 패킷전달 가능성이 높은 다중경로 라우팅 프로토콜 아이디어를 제시한다.

This study was performed to test the socioemotional selectivity theory (SST) with Korean adults. According to SST, perceiving their life as limited, people are motivated to enhance their mood by regulating their mood in such a way to maximize the positive emotions and weaken the negative ones. Being founded on the dialectical constructs which assume the positive and negative sides of emotional experience coexist, Korean adults were supposed to be less motivated to maximize positive emotions and weaken negative emotions. Thus the elderly koreans might regulate emotions not in the direction of maximizing the positive emotions and weakening the negative ones, but in the direction of not being highly aroused. 166 youth, middle-aged, and elderly were asked to rate the frequencies of 31 positive and negative emotions they had experienced during the last month. In addition, they were asked to judge whether they weaken / adapt / maximize their emotions after experiencing positive and negative events. The elderly experienced less positive emotions as well as negative emotions than youth. Youth experienced emotions of high arousal more often than those of low arousal, but the elderly experienced emotions of high arousal less often. The responses of weakening their negative emotions and their positive emotions were largest in the elderly group. On the other hand, the response of maximizing their positive emotions were largest in the youth group. These results show that the elderly maintains emotional stability by weakening both positive and negative emotions of high arousal.

The purpose of this study was to find out the relations between elementary children's game addition, aggression, and personality, by making a survey with 360 children of 5th and 6th grade in the Metropolitan are. The results were made as follows: First, as it examined the real condition of computer addition, it presented a low level of addiction. There was a meaningful difference according to their gender, however no meaningful differences were found between the grades. It found that the more they had game experience, game frequency, game concentration, the more they were addicted. Second, there were significant differences when investigated the relations of game addiction and aggression, students who were in severe addicted group showed more aggressive attitudes. Aggression in general, seemed less related to the gender, but related to the level of addiction, showing higher level of physical, linguistic, negative, indirect aggression in the more addicted group. Third, when it compared the difference between the general personality by the level of game addiction, there was a meaningful difference statistically in the addicted level of p<0.01. In detail, more addicted children showed low level of sociality, achievement, mobility, stability, and they showed lower figures in comparison with normal user group. It is interpreted that they dislike to get along with friends, and unstable emotionally.

The aim of this study is to develop and construct the elements of a new evaluation tool to assess the effectiveness of a horticultural therapy. Delphi method was applied to classify the realms of evaluation and specify their components and constituting items. Delphi process was performed through three rounds and 24 professionals attended all the rounds as panel members. Some of the items were revised or removed according to the results of such tests as content validity ratio, agreement rate, convergency and stability of each item. On the contrary, a few new items were added by accepting the opinions of the professional panels. Previous to the Delphi, the realms of evaluation were classified into physical, cognitional, psycho-emotional and social ones on the basis of literature review, professionals' consultation and in-depth interview with practitioners. At the first round, 112 items constituting four realms were reviewed. The numbers of items to be reviewed were reduced to 107 at the second round and to 102 at the third round. As a result, 98 items in 4 realms were decided as proper evaluation points of horticultural therapy. The compositions of the four respective realms are as follows: 5 components and 27 items in physical realm; 4 components and 25 items in cognitional realm; 2 components and 24 items in psycho-emotional realm; and 4 components and 22 items in social realm. These realms, components and specific items derived from this study constitute indices to evaluate the effectiveness of horticultural therapy. In addition, they might be utilized as good guidelines for planning horticultural therapy programs.

The study is to examine the psychophysiological responses evoked by negative emotions(fear and disgust) in children. 47 children(11-13 years old, 23 boys) participated in the study. While the children were experiencing fear or disgust emotion induced by audio-visual film clips, ECG, EDA, PPG and SKT are measured. Emotion assessment scale was used to confirm that emotions elicited by the film clips were significantly noticeable, which was measured self-report. The results turned out to be 100% and 89.4% of appropriate for fear and disgust emotions, respectively. Emotional intensity the children had experienced was rated as 4.05, 4.07 on 1-5 scale based on effectiveness of measurement of fear and disgust emotion. ANS reponses by fear and disgust were significantly between the resting state and emotional state induced. The result obtained from the fear emotion showed significant increases in SCL, NSCR, HR, RSA, RESP and HF. There was a significant difference in SCL and NSCR between the two emotions.

정상 성인의 경우, 감성 개념의 내적 차원 구조는 쾌/불쾌 차원과 각성 차원이라는 2차원 구조에 원형의 체계적인 분포를 보이는 것으로 알려져 왔다. 본 연구에서는 이와 같은 2차원 구조가 얼마나 보편적이고 일관된 양상으로 나타나고 있는지를 살펴보고자 하였다 이를 위해 연구1에서는 아동 및 청소년에게 15개의 정서 관련 어휘로 이루어진 10i개의 단어 쌍에 대한 7점 척도의 유사성 평정을 시행하였으며, 연구 2에서는 정신분열증 환자에게 통일한 절차를 시행하였다 다차원 분석 결과, 1차원(초등5년:74%, 중등2 년:72%, 정신분열증 환자: 60%)과 2차원(초등5년: 18%, 중등2년16%, 정신분열증 환자: 11%)이 도출되었다 정상 성인의 경우와 마찬가지로 1차원은 쾌/불쾌 차원, 2차원은 각성 차원으로 해석될 수 있었다. 따라서, 감성 개념의 구조에 있어서 쾌/불쾌 및 각성은 인지적 성숙의 단계나 인지, 정서적 손상에 관계 없이 매우 일관되게 나타나는 비교적 안정적인 차원 구조인 것으로 생각된다. 다만, 발달 단계나 병리적 속성에 따라 각 차원의 비중치는 다소 차이를 보이는데, 아동 및 청소년의 경우, 주로 쾌/불쾌 차원을 통해 감성을 개념화 하는 특징을 보이며, 정신분열증 환자 집단의 경우, 1,2차원 모두 상대적으로 설명량이 낮은 것으로 나타나는데, 의 경우, 비중치가 더욱 낮은 것으로 나타났다. 이러한 결과를 통해 내적 차원 구조의 타당성 및 제한점에 관해 논의하였다.
