데이터베이스에서 트랜잭션의 처리량을 향상시키기 위해서 기존의 문법 위주의 직렬성 이론으로는 단위시간당 처리량을 높이기는 힘든 형편이다. 이를 위하여 이타적 잠금 기법(altruistic locking: AL)은 트랜잭션이 객체를 사용한 다음 더 이상 그 객체를 요구하지 않을 때 다른 트랜잭션들이 그 객체를 로크할 수 있도록 미리 객체에 대한 로크를 해제함으로써 트랜잭션들의 대기시간을 줄이고 처리량을 향상시키기 위한 취지에서 제안된 것이다. 확장형 이타적 잠금(extended altruistic locking: XAL)기법은 AL 을 자취의 확장한 것으로 AL 이 근본적으로 안고 있는 반드시 기부된 객체만을 처리해야 한다는 제약을 완화한 기법이다. 본 논문에서는 분산 데이터베이스 환경하에서 장기 트랜잭션으로 인한 단기 트랜잭션의 대기현상을 최소화하도록 함으로써 동시성 제어의 정도를 높일 수 있는 새로운 확장형 이타적 잠금 기법인 양방향 기부기법(two-way donation locking: 2DL)을 제안하고 기존의 제어기법과 비교하였다. 모의실험에 의한 성능평가 결과 2DL 은 작업 처리율과 트랜잭션의 평균 대기시간 면에서 우수한 결과를 나타내었다.

This study investigated the relationship of brand equity of restaurant LOHAS image with altruistic value, LOHAS involvement and additional willingness to pay (WTP). The data collected for this study was taken from a sample of 544 persons during the period of August 1, 2013 to August 31, 2013. The study findings are as follows. First, brand equity and brand association of restaurant LOHAS image had a positive effect on altruistic value, but had no positive effect on brand loyalty and perceived product quality. Second, brand awareness, brand loyalty and brand association of restaurant LOHAS image had a positive effect on LOHAS involvement, but had no significant positive effect on perceived quality. Third, altruistic value was found to have a positive effect on LOHAS involvement. Fourth, altruistic value had a positive effect on additional WTP. Fifth, LOHAS involvement was found to have a significant positive influence on additional WTP. The findings of this study indicate that communication strategies are warranted to emerge environmental friendliness and health targeting population groups that pursue the LOHAS value of restaurants or have a high propensity toward altruism.

The purpose of this study was to examine knowledge, attitude, and altruism on blood donation and influential factors in regard to its experience. Data were collected through questionnaires with a convenience sample of 311 healthcare providers. Subjects with blood donation experience accounted for 63.3%. In both nurses and laboratory technologist, the rate of blood donation in male group has higher than that of female group. There were differences in the knowledge of blood donation dependent upon the type of occupation of healthcare providers and the higher age and the longer period of career experience proved to be the significant factor for the level of altruism. The study suggests that more practical, concrete strategies should be identified to participate in blood donation. The further relevant variables need to be investigated since the most determinant motivator for blood donation among healthcare providers was the responsibility to help others.

In this paper, we present an advanced transaction scheduling protocol to improve the degree of concurrency and satisfy the security requirements for multilevel secure database. We adapted two-phase locking protocol, namely traditional syntax-oriented serializability notions, to multilevel secure database. Altruistic locking, as an advanced protocol, has attempted to reduce delay effect associated with lock release moment by use of the idea of donation. An improved form of altruism has also been deployed for extended altruistic locking OffiLl. This is in a way that scope of data to be early released is enlarged to include even data initially not intended to be donated. We also adapted XAL to multilevel secure database and we first of all investigated limitations inherent in both altruistic schemes from the perspective of alleviating starvation occasions for transactions in particular of short-lived nature for multilevel secure database. Our protocol is based on extended altruistic locking for multilevel secure database (XAL/MLS), but a new method, namely two-way donation locking for multilevel secure database (2DL!/-MLS), is additionally used in order to satisfy security requirements and concurrency. The efficiency of the proposed protocol was verified by experimental results.

Objectives: The purpose of this study was to assess organizational citizenship behaviors (OCBs) and organizational personality types (OPT) perceived by public health center workers and to analyze differences in perceptions according to organizational characteristics. Methods: The subjects of this study were workers at 12 of the 22 public health centers in Chonnam Province, South Korea. To measure organizational characteristics, we employed the OPT Index and OCBs Index. Data were collected for one month, from 15 September to 14 October 2009. Data for 422 workers were used in the final analysis. Descriptive statistics and t?tests were performed as appropriate, utilizing SPSS/WIN 14. Results: Among 16 types of OPT, ESTJ, ISTJ and ESTP were the most prevalent for the 12 public health centers. The average weight of OCBs was 4.77, and courtesy and civic virtue held the first and the second ranks among OCBs, respectively. Statistically significant differences between types of OPT were detected, in that T type was gender (p=.007) while J type was age (p=.010), education (p=.043) and career (p=.000). Statistically significant differences between OCBs were found in age, education and career. Conclusion: Public health centers should have programs to innovate OPT and to improve OCB. The development of such programs should consider characteristics of public health center workers such as age, gender, education and career.

We propose an advanced transaction scheduling protocol for concurrency control of multilevel secure databases in wireless mobile network environment. Wireless communication is characterized by frequent spurious disconnections. So short-lived transaction must quickly access database without any delay by long-lived one. We adapted two-phase locking protocol, namely traditional syntax-oriented serializability notions, to multilevel secure databases in wireless mobile network environment. Altruistic locking, as an advanced protocol, has attempted to reduce delay effect associated with lock release moment by use of the idea of donation. An improved form of a1truism has also been deployed for extended a1truistic locking. This is in a way that scope of data to he early released is enlarged to include even data initially not intended to be donated. Our protocol is based on extended altruistic locking, but a new method, namely bi-directional donation locking for multilevel secure databases (MLBiDL), is additionally used in order to satisfy security requirements and concurrency. We showed the Simulation experiments that MLBiDL outperforms the other locking protocols in terms of the degree of throughput and average waiting time.

Based on that the purpose of professionalization in librarianship is to achieve social recognition of its specialty, we discuss about theoretical background for the professionalization in librarianship in Korea. Some characteristics from the previous discussions are identified, such as functionalism, altruism in service, and individualism. Also, we identify organization-centered characteristic as an inherent one in librarianship. Based on the characteristics identified, we discuss about some supportive concepts, such as advanced or complex knowledge, service, organization-centered characteristic, and market, and their interrelationships. We hope such concepts would encourage further discussions on this topic for the professionalization.

While the endeavor to introduce the service activity in the college education is enlarged, the object of this study is to introduce the concept of service learning in social work education. The 'Service-Learning' is focusing on the practical education, the liaison and participation in community and the promotion of civil awareness which are very important in social work education that focuses on the interest and participation in the human and social problem as practical study. This study contemplates the educational effect of the course of social work combined with service learning. This study verifies the change of the self-efficacy, the altruism, social responsibility as personal growth of students by carrying out the course of social welfare and service activities side by side. To investigate the learning effect qualitative analysis in journal of service activity was done. Through the service learning, students showed the promotion in self-efficacy, social responsibility. And as a result of qualitative analysis, it was found that students could participate in the intervention of family problems, could have lots of understanding of theory, could increase the interest of family welfare, could experience a change of perception about the client. Based on the above mentioned results, this study address that Service-Learning is useful teaching methodology in social work education to accomplish the personal growth of students and promote the learning effects.
