Microblog services are such new communication channels with some considerable potential to improve information sharing. The idea of sharing short messages using multiple access points seems to be appealing to people worldwide. Through the lens of flow and social identity, we explored factors that influence information sharing behaviors in microblog services. With an empirical study, we examined enjoyment and concentration(flow) and self-presentation(social identity) in microblog services like twitter can contribute to the user behaviors. Our aim was to gain insight into ways of creating an environment that facilitating voluntary sharing of information. Our findings suggested that enjoyment, concentration, and selfpresentation were crucial determinants of information sharing behaviors in microblog services. This study has important implications for academic researchers and practitioners who seek to understand why microblog service users share their information with other members in microblog services.

The present study aimed to examine the relationships between work-related support factors and attitude towards teleworking and explore the moderating effect of self-identity on that relationship. The present study collected data from 343 IT professionals in South Korea through a survey method and used hierarchical multiple regression analyses. In the results, first, the more supervisory or work-related supports participants perceive in teleworking platforms, the more favorable their attitudes towards teleworking. Second, the positive relationship between supervisory support and attitude towards teleworking is stronger for participants high rather than low in interdependent self-view. However, interdependent self-view was found to have no significance on the relationship between work colleague support and attitude towards teleworking. This study is the first to examine the integral model of work-related support factors of attitude towards teleworking and explore the moderating effect of self-identity in the teleworking process.

현재까지 제안된 대부분의 신원기반 키 동의 프로토콜은 단일 PKG(Private Key Generator) 환경을 고려하고 있다. 2002년에 Chen과 Kudla는 처음으로 다중 PKG 환경을 고려한 신원기반 2자간 키 동의 프로토콜을 제안하였지만 이들은 PKG의 마스터키를 제외한 다른 시스템 파라미터는 공유한다고 가정하고 있다. 그러나 PKG의 마스터키 이외에 다른 파라미터마저도 공유하지 않는 것이 보다 현실적인 가정이다. 이 논문에서는 시스템 파라미터를 공유하지 않는 각 PKG들로부터 개인키를 발급 받은 두 사용자들 간의 2자간 키 동의 프로토콜과 이를 확장한 두 가지 버전의 3자간 키 동의 프로토콜을 제안한다. 제안된 2자간 키 동의 프로토콜은 다중 PKG 환경에서 최소의 pairing 연산량을 요구하며, 제안된 3자간 키 동의 프로토콜은 다중 PKG 환경에서 기존의 3자간 키 동의 프로토콜들에 비해 효율적이다. 또한 제안된 키 동의 프로토콜들은 키 동의 프로토콜의 보안 요구사항을 만족한다.

Methods: Data were collected by self-reported questionnaires from 308 female university students. Data analysis was done with SPSS 10.1 for descriptive statistics, ANOVA, and Duncan's multiple-range test. Results: The most prevalent type of premenstrual syndrome was androgenic(33.8%), followed by undifferentiated(25.0%). There was a significant difference in dysmenorrhea according to residence. In addition, there were significant differences in premenstrual syndrome according to age, and in stress according to age and economic status. Also, there was no significant difference according to dysmenorrhea and there were significant differences in premenstrual syndrome and dysmenorrhea according to gender role identity. Premenstrual syndrome and stress were the most prevalence in female type, but the lowest severe in masculine type.

College students were used to employ many obligate time including studying. Their peak time was 10 a.m., 6 p.m. or 10 p.m., and their slump time was from 7 a.m. to 9, or from noon to 2 p.m.. They enjoyed on weekend, and then tired on Monday. 2. College students were satisfied with the future time use than the present. In survey of self-identity inventory, they lacked confidence in their future, but they oriented their goal and were familiar with the social network. 3. The more college students satisfied time use, the more the level of self-identity was high. This, it was suggested the program of time management for college students.

Purpose: This study aimed to examine the factors associated with postpartum depression and its influence on maternal identity of postpartum women. Methods: Research design was a cross sectional descriptive study with a total of 89 women within the six month postpartum period. Associations of eating habits, overall sleep quality and other factors with postpartum depression utilizing the Korean Beck Depression Inventory (K-BDI) were done. The influence of postpartum depression on maternal identity was analyzed. Variables yielding significant associations (p<.05) were included in an adjusted logistic regression and a stepwise multiple regression. Results: Mean scores of postpartum depression was $9.42{\pm}6.08$ and 31.5% (n=28) for mild depression, 11.2% (n=10) was moderate and 4.5% (n=4) was severe depression on the K-BDI scale. Perceived health status and overall sleep quality were predictors of postpartum depression. Postpartum depression and the husband's love were predictors of maternal identity. Conclusion: Awareness of poor health perception and sleep quality will be helpful to detect for postpartum depression. Strategies to increase maternal identity during the postpartum period would be tailored by level of depression.

본 연구는 종합병원 병동간호사의 전문직정체성과 역할갈등, 직무스트레스, 직무만족를 조사하고, 전문직정체성과 역할갈등, 직무스트레스가 직무만족에 미치는 영향을 파악하기 위한 서술적 조사연구이다. 연구대상자는 K 지역에 소재한 종합병원 간호사 193명이다. 수집된 자료는 IBM SPSS Statistics 22.0 program을 이용하여 빈도와 백분율, 평균과 표준편차, independent t-test, one-way ANOVA, pearson's correlation coefficient, multiple stepwise regression을 이용하였고 사후검증은 scheffé test로 분석하였다. 연구결과 첫째, 일반적 특성 중 종합병원 병동 근무경력이 전문직정체성과 통계적으로 유의한 차이가 있었고 병동 근무경력이 낮을수록 전문직정체성이 높은 것으로 나타났다. 둘째, 전문직정체성은 직무만족 및 역할갈등과 정적상관관계, 직무스트레스는 부적상관관계로 나타나, 전문직정체성이 높을수록 직무만족과 역할갈등은 높았지만 직무스트레스는 낮았다. 역할갈등은 직무스트레스와 정적 상관관계를 보여 역할갈등이 높을수록 직무스트레스가 높았다. 셋째, 직무만족에 영향을 미치는 요인은 직무스트레스, 전문직정체성 순으로 나타났으며 그 영향력은 38%로 나타났다. 따라서 간호사들의 직무만족 향상을 위해 전문직정체성 확립을 위한 전문화된 교육프로그램 개발 및 적용이 필요하며, 간호수행 시 발생하는 직무스트레스 해소를 위한 인적·물적 지지체계가 구축되어야 한다.

단위행렬의 각 행을 공간부호로 사용하고 symmetric balance incomplete block design(BIBD) 부호를 스펙트럼부호로 사용한 2차원(2-D) 하이브리드 부호를 제안한다. 단위행렬의 각 행을 공간부호로 사용함으로써 수신기의 구조가 간단해지고 송수신단을 연결하는 방법도 간단해 짐을 알 수 있었다. 또한 비이상적 BIBD 부호를 스펙트럼부호로 사용하여 입력신호가 작을때도 효율적으로 동작할 수 있었다. 사용자 수에 따른 비트 오차율(BER) 분석을 통하여 제안하는 2-D 하이브리드 부호가 1차원(1-D) BIBD 부호에 비하여 최대사용자 수를 현저하게 증가시킬 수 있음을 알 수 있었다.
