Perceptions of organizational politics(POPs) have stress-based effect as job demand and lead to employee's negative attitudes and behaviors. According to job demand resource model, burnout develops when high job demand deplete employee's resources, which lead employees to low levels of motivation and high levels of cynicism and frustration. Currently, in studying the relationship between POPs and burnout there is a lack of researches on certain settings and conditions. The present study examined a model in which relationship between POPs and burnout was mediated by psychological need satisfaction. And also, this study tested moderating role of psychological capital between POPs and need satisfaction. A total of 220 employees in telco and electronic manufacturing company in South Korea participated in this study. The result of this study showed that need satisfaction works as mediating variable between POPs and burnout and psychological capital had moderating effect between POPs and need satisfaction. This study proposes a new framework of POPs by examining linking mechanism of need satisfaction and psychological capital. The results of this study provide practical insight to HR practitioners and business leaders.

It is a very important task for managers to motivate employees who work at service encounters where interaction with customers is important. The purpose of this study is to propose the trust of supervisor and supervisor's expressions as factors that can enhance or strengthen employees' prosocial behavior. Hierarchical regression analysis was used for this purpose. The results and implications are as follows. First, trust toward supervisors appeared to be a factor to improve employees'engagement. Second, job engagement has a positive effect on prosocial behavior of employees, that is, customer oriented behavior and organizational citizenship behavior. Finally, this work confirmed the moderating effect of the supervisor's gratitude expressions in the relationship between trust toward supervisor and job engagement. Research on gratitude in the marketing field is still in its infancy, and previous researches are focused on business and consumer relations. Expressing gratitude can be a natural tendency. This study suggests that gratitude expression should be introduced as part of organizational culture.

In this paper, I raise an issue regarding the relationships between the Election problem and the Consensus problem in asynchronous systems with unreliable failure detectors. First, I describe our system model, and then define Leader Election. After then, I show that the Election problem is harder to resolve than the Consensus problem. Each correct process eventually gets into the state in which it considers only one process to be a leader. Therefore a Perfect Failure Detector is the weakest failure detector which is sufficient to solve the Election. In order to show that the Election problem is harder to resolve than the Consensus problem, I utilize the Reduction protocol in this paper.

When library performance is regarded as service quality, competency in human resources should be considered as an influential factor. This study aims to identify relationships between job satisfaction of librarians and the service quality that users recognize in public libraries. Librarians and users in 10 public libraries in Seoul, Incheon, Gyeonggi province were sampled to measure job satisfaction and service quality with $LibQUAL+^{TM}$ model. As a result, the higher the satisfaction of the duty itself and organizational factor show a high service quality. Consequently, to improve library customer satisfaction, the librarian's job satisfaction should be considered. Additionally, some practical implications are discussed.

To Study the relationships between rapeseed yield and meteorogical elements, the investigation into the important agronomic characters of Yudal cultivar and climate factors such as precipitation, and temperature from 1975 to 1984 was made. Yearly variation of C. V.(%) were highly significant for yield and the important agronomic character. Correlation coefficients between precipitation of May and Yield or agronomic character were significantly positive. Regression equations between the precipitation of Mayor minimum temperature of February and yield were Y=210.914+1.719X and Y=245.560-1.720X, respectively. Low temperature of February affected rapeseed yield reduction significantly.

그래프 학습 기술은 실세계의 네트워크를 그래프로 모델링하여 분석함으로써, 네트워크에 내재된 유용한 정보를 도출하는 핵심적인 역할을 한다. 그러나 기존의 그래프 학습 기술에는 두 가지 한계점이 존재한다: (1) 그룹 정보 표현의 한계 및 (2) 동적 관계 학습의 한계. 각 한계를 극복하기 위해 하이퍼그래프 학습 기술과 동적 그래프 학습 기술이 활발하게 연구되었지만, 두 가지 한계를 동시에 극복하기 위한 연구들은 아직까지 충분히 수행되지 못했다. 이러한 동기로부터, 본 논문은 실세계 네트워크를 동적인 하이퍼그래프로 모델링하여, 동적 그래프 학습 기술, 정적 하이퍼그래프 학습 기술, 그리고 동적 하이퍼그래프 학습 기술들의 성능에 대해 비교 분석하고자 한다. 실험 결과, 시간에 따라 변화하는 실세계의 복잡한 관계를 정확하게 포착하는 데는 동적 하이퍼그래프 학습 기술이 가장 효과적이라는 것을 확인하였다.

SNS enables people to easily connect and communicate with each other. People share information, including personal information, through SNS. Users are concerned about their privacies, but they unconsciously or consciously disclose their personal information on SNS to interact with others. The privacy of a self-disclosed person can be intruded by others. A person can write, fabricate, or distribute a story using the disclosed information of another even without obtaining consent from the information owner. Many studies focused on privacy intrusion, especially from the perspective of a victim. However, only a few studies examined privacy intrusion from the perspective of an intruder on SNS. This study focuses on the intention of privacy intrusion from the perspective of an intruder on SNS and the factors that affect intention. Privacy intrusion intentions are categorized into two types. The first type is intrusion of privacy by writing one's personal information without obtaining consent from the information owner;, whereas the other type pertains to intrusion of privacy by distributing one's personal information without obtaining consent from the information owner. A research model is developed based on motivation theory to identify how these factors affect these two types of privacy intrusion intentions on SNS. From the perspective of motivation theory, we draw one extrinsic motivational factor (response cost) and four intrinsic motivational factors, namely, perceived enjoyment, experience of being intruded on privacy, experience of invading someone's privacy, and punishment behavior. After analyzing 202survey data, we conclude that different factors affect these two types of privacy intrusion intention. However, no relationship was found between the two types of privacy intrusion intentions. One of the most interesting findings is that the experience of privacy intrusion is the most significant factor related to the two types of privacy intrusion intentions. The findings contribute to the literature on privacy by suggesting two types of privacy intrusion intentions on SNS and identifying their antecedents from the perspective of an intruder. Practitioners can also use the findings to develop SNS applications that can improve protection of user privacies and legitimize proper regulations relevant to online privacy.

Gwanak-yeongsanhoesang, called as Samhyeon-yeongsanhoesang or Pyojeongmanbangjigok, is played by the musical instrumental organization, Samhyeonyukgak or by a large scale wind ensemble added Sogeum and Ajaeng. This study aims to analyze the structure and form of Piri melody which plays major melody of Sangnyeongsan in Gwanak-yeongsanhoesang, and to examine the relationship between Piri melody and Daegeum yeoneum grasping the structure and function of yeoneum. In Sangnyeongsan of Gwanak-yeongsanhoesang, the criterion for grouping the phrases of Piri melody is yeoneum. Especially, Daegeum yeoneum carries out the function of finishing the phrase of Piri playing the major melody by ornamenting or extending it, and presenting the motives or motive elements of the next phrase while Piri rests. The types of a, b, g, and i in the various shapes of the minimum melodic fragment of Piri are important motive elements that constitute a phrase of Piri melody. Especially, main motive a-type (仲→無) contrasts with b type (林→潢) which forms a strong tension by transposing 2 degrees upward. In addition, a-type gradually descends towards the end of music by changing to g-type (仲→林) or to i-type (太→林) which is 3 degrees below, which is related to the gradual descent cadence of Korean traditional music. A phrase of Piri melody of Sangnyeongsan in Gwanak-yeongsanhoesang consists of a combination of the types a, b, g, i, and cadence (x-type), and each phrase is structured in the repeating tension-relaxation. Looking at the structure of Piri phrases by similar types, each phrase has a logical variation structure through the methods such as omission and addition of notes, and crossing of melodies. The shape of the minimum melodic fragment of Daegeum yeoneum can be divided into a back-yeoneum of a~b types and a front-yeoneum of x1~x3. The x-types ornament Jungnyeo (仲), the cadence tone of Piri melody or are simply used as the extending back-yeoneum, and types a and b have the function of a front-yeoneum that prepares the beginning of the next phrase of Piri melody. The combination types of the minimum melodic fragment of Daegeum yeoneum appear mostly as the shape of back-yeoneum + front-yeoneum. In addition, the front-yeoneum of the type a and b appears independently without back-yeoneum, and the x3 type has a shape of the back-yeoneum without the front-yeoneum. Looking at the structure of Daegeum yeoneum by similar types, it can be seen that Daegeum yeoneum is also composed of a variation structure of omission and addition of notes like Piri melody.
