Defining prediction variables related to metamemory for the adults in aging process has worthwhile meaning from the perspective that the produced results can be helpful to reducing the difficulty of memorizing efforts and it can also enhance quality of life of aged. This study attempted to analysis relationship between perceived health status, depression, memory self-efficacy and meta memory for the subjects of middle age and old age adults. This study was designed by adopting descriptive correlational analysis method for the 468 middle and old age adults who are living in Seoul. Samples were selected by convenience sampling. Data collection was done over 1 month period in june 1998. The instruments used in this study were health status measuring scale including depression measuring scale, memory self efficacy measuring scale and metamemory measuring scale which were verified for reliability. Data collected were analized by using SPSS for frequency, Peason correlation, t-test and ANOVA according to the variables character and the study purposes. Results of the study were as follows. 1. Relationship between perceived health status, depression, memory self-efficacy and metamemory. Relational analyses between perceived health status, depression, memory self-efficacy and metamemory supported the hypotheses of 1st, 2nd and 3rd(p < .01). These results suggested that the aged perceived great health status then their memory self-efficacy, and metamemory showed the high scores. In the case of depression when its level became decreased metamemory was inclined to increased. Thus, it is identified that strong relationship exists between these variables. 2. Perceived health status, depression, memory self-efficacy by subject's general characteristics. Scores of perceived health status were high in the group of man compared to the group of women, and also highly educated group showed great perceived health status. Group of persons having occupation showed high score of perceived health status and low depression score. The score of memory self-efficacy and metamemory showed higher in the middle aged than the old aged. The high scores of memory self-efficacy and metamemory were found in the group of highly educated people and who have continuing education. The high scores of memory self-efficacy were found in the group of persons having their job and high metamemory scores found in the group of persons having religion. In summary, the greater perceived health status and memory self-efficacy, the more metamemory scores were likely increased and the more depression level was decreased, the more metamemory was likely increased. Also it was found that general characteristics like educational level, continuing education and religion influenced the metamemory of the aged. Therefore, prevention the aged from getting depression and activation of health promotion are needed to delay time of memory loss.

The purpose of this study was to provide information on the development of an oral-health promotion program geared toward office workers. The subjects in this study were 240 employees at the headquarters of S construction company. After a survey was conducted in July and August 2008, the answer sheets from 208 respondents were gathered, and 191 answer sheets were analyzed except 17 unanalyzable ones. The findings of the study were as follows: 1. In regard to subjective oral health status, the largest number of the participants that accounted for 37.2% found their mouth to be neither healthy nor unhealthy. The greatest number of them that represented 58.1% had never visited a dentist's office to receive preventive treatment. 2. Regarding relationship between toothbrushing education experience and toothbrushing frequency, the most common toothbrushing frequency was three times a day( 46.5%) among the company employees who had ever received that education. In the event of the office workers without that experience, the most prevalent frequency was three times(63.6%). The toothbrushing frequency was statistically significantly different according to the toothbrushing education experience(p<0.05). As to the relationship of toothbrushing education experience to tooth- brushing method, the largest number(48.2%) of those who had ever received that education brushed their upper and lower teeth along with the gums by rotating the toothbrush downward from the top and upward from the bottom respectively. In the event of the office workers without that experience, 49.4 percent brushed their teeth and gums by rotating the toothbrush up and down. Thus, whether they had ever received education about toothbrushing made a statistically significant difference to their toothbrushing method(p<0.05). 3. As a result of evaluating their oral health belief by utilizing a five-point scale, they got a mean of 2.95. In each area of oral health belief, they got the best marks in benefit(3.66), salience(3.42), barrier(2.84), susceptility(2.58) and seriousness(2.23). Given the above-mentioned finding of the study, two sorts of oral health beliefs, which are benefit and salience, should be stressed in the development of oral health education programs that cater to company employees. And sustained research efforts should be channeled into finding out the relationship between oral health and actual oral health care.

Increasingly the information technology (IT) outsourcing phenomenon has been a subject of much academic research. Scholars have argued that knowledge complementarities playa crucial role in forming successful IT outsourcing relationships. However, notwithstanding the fast growth of IT outsourcing, prior studies on IT outsourcing have not included knowledge complementarities in their research design as a determining factor for IT outsourcing effectiveness. Further, the understanding of knowledge complementarities itself remains ambiguous. In this study, the concept of knowledge complementarities is explored in the IT outsourcing context at the firm level. Specifically, it addresses the following questions: what is knowledge complementarities? How does it affect IT outsourcing effectiveness? Is the relationship between knowledge complementarities and IT outsourcing effectiveness influenced by organizational trust between the client and the vendor? Grounded in the relevant theories to knowledge management and IT outsourcing, we develop a research model in which both the main effects of knowledge complementarities and organizational trust and the moderating effect of organizational trust on the relationships between knowledge complementarities and IT outsourcing effectiveness are tested. Within this research model, we develop a second order construct of knowledge complementarities, consisting of complementary business knowledge and complementary IT knowledge as the first order constructs. We have used data from a field study of 103 firms in Korea to test the proposed model. Controlling the effects of conflict resolution efforts, our empirical analysis found significant main effects of knowledge complementarities and organizational trust on IT outsourcing effectiveness. The results suggest that knowledge complementarities between the client and vendor positively contribute to IT outsourcing effectiveness. Specifically, the client needs to have enough IT knowledge to assess the quality of IT outsourcing services provided by the vendor. Meanwhile, the vendor should understand the client's business well enough to provide IT services, Contrary to our expectations, the moderating effect of trust on the relationship between knowledge complementarities and IT outsourcing effectiveness was not supported in this study. The results also show that organizational trust between client and vendor significantly influences IT outsourcing effectiveness. As for contributions of this study, we have not only clarified the concept of knowledge complementarities, but also developed an instrument to measure the concept and empirically validated it. Further, we have tested the idea that knowledge complementarities and trust directly influence IT outsourcing effectiveness and trust moderates the relationship between knowledge complementarities and IT outsourcing effectiveness. Out results prescribe the knowledge complementarities of client and vendor as a useful path to IT outsourcing effectiveness. These findings have important theoretical and practical implications, which are discussed in the paper.

The purpose of this study was to investigate the relationship between the dietary attitude and health on the stress status of office - workers in Seoul. This research was conducted on 389 office workers (224 males and 165 female). In relation to stress, it was found that the degree of stress as an office workers was ′slight′ and much for 45.2% and 40.6%, respectively, of the study population. Consequently, most office workers were found to be under stress. The amount of food intake under stress was found to be ′reduced′, unchanged and increased in 38.3, 37.0 and 24.7%, respectively, of those surveyed. The preferred foods when under stress were found to be alcoholic and non-alcoholic beverages, in 57.6% of cases, which was the highest proportion regardless of age, sex, marital status, occupation and educational level. The desired taste when under stress was found to be ′hot′ and sweet in 34.7 and 26.0%, respectively. As to the feeling after food intake, 51.7% responded that food intake was not useful for the relief of stress, which was the highest proportion and many salaried females worried about weight gain. With regard to the relationship between stress, health and nutrition, 69.9% of office workers responded that they thought the relationship of these factors was very high. As for the greatest cause triggering stress, 50.3% responded "due to workplace and job". The best method for relieving stress was to do exercise, with a 30.1 % response, The average score for the degree of stress and tension was 7.2, with 64.0% of office workers having an average level between 6- and 9. The degree of stress was higher for females than males, for unmarried salaried and hot-tempered persons. Those not doing exercise were subject to the highest levels of stress, and those a having sufficient sleep were found to be subject to less stress. Those interested in their health were found to have a good condition and lower levels of stress. In correlation with eating habits, stress, the degree of tension and personality, the F-value was found to be 43.505 (p<0.01), with an explanatory power of 0.294 (29.4%), indicating significant differences. This means that office workers with higher degrees of stress and tension tended to have poorer eating habits. Since bad eating habits have an adverse effect on both the state of physical health and individuals emotional development, for the purpose of correctly managing stress, office workers should make efforts to practice good eating habits.

Purpose - This paper attempted to investigate the relationships among the perception of job insecurity and organizational effectiveness, and it examines these relationships while considering the moderating effect of trust in the manager and self-efficacy. Job insecurity is an independent variable, organizational effectiveness aspects (job satisfaction, organizational commitment, and turnover intention) are dependent variables, and trust and self-efficacy are moderators. Research design, data, and methodology - Regression analysis was used to verify the effects. The measurement items were already deemed as reliable and valid in the previous study, but for this purpose, some modifications were made. To examine the model, this study relied on the samples chosen from Korean employees in the six franchise business firms. The survey was conducted on 288 workers. Each question is based on a 5-point Likert type scale. The data were analyzed using SPSS 18.0. Results - The results of the study are summarized as follows. First, job insecurity has an influence on organizational effectiveness aspects (negatively on job satisfaction, negatively on organizational commitment, and positively on turnover intention). Second, analyzing the moderating effect of trust, trust in manager is mediated between job insecurity and organizational effectiveness aspects (on organizational commitment and on turnover intention). However, employees' trust in manager had no significant moderating effect on the job insecurity-job satisfaction relationship. Third, self-efficacy is mediated between job insecurity and organizational effectiveness aspects (on job satisfaction, on organizational commitment, and on turnover intention). Conclusions - First, it is necessary to be aware of the seriousness of employees' job insecurity in franchise firms, which have played a pivotal role in national economic growth, and to create a detailed plan for reducing insecurity and actively implementing it. To this end, the franchise companies should implement efficiency efforts such as obtaining an appropriate capacity of equipped personnel and a training program. Second, there are moderating effects of self-efficacy and trust in the relationship between job insecurity and organizational effectiveness. Depending on business conditions, stability and instability can only be experienced in the organizations of franchise companies. This can give rise to instability in employment. Therefore, it is necessary to develop and utilize a system that can be minimized with a change in the new awareness of employment instability. After all, a good leader (manager) must accumulate personal trust and build up a core competence that is necessary to become competent in the field himself. Even if you lack the material resources to improve performance, if the leader with the core competencies (e.g., technical/management /organization/marketing/design) can gain the trust of the supervisor, you can get a good organizational performance. Therefore, you should foster a healthy organizational culture through education such as leadership training and employee training to be built on trust between the leaders and the employees. In addition, you need to focus on HRD&M training in order to increase the self-efficacy of the supervisor.

글로벌화와 고용시장 변화에 따른 경력 환경의 불확실성은 노동시장을 경쟁적으로 변화시키며 근로자의 고용불안을 더욱 확대시키고 있다. 이러한 환경에서 제기되는 개인 주도의 새로운 경력 패러다임은 경력 주체가 주관적으로 느끼는 내재적 관점의 경력성공을 중요한 경력 성과임을 강조하고, 이를 위한 개인의 경력 계획의 중요성이 더욱 부각되었다. 그리고 경력성공을 위해서는 개인의 경력계획뿐만 아니라 경력계획을 통해 개인이 인지하는 조직 및 직무적합성 또한 중요하다. 이러한 배경에서 이 연구는 개인의 경력계획이 주관적 경력성공에 미치는 영향과 그 관계에서 개인-조직적합성 및 개인-직무적합성이 매개효과를 가지는지 검증하고자 하였다. 직장인 220명에 대한 설문 조사 결과, 경력계획은 주관적 경력성공에 긍정적인 영향을 나타냈으며, 개인-조직적합성과 개인-직무적합성 모두 매개효과를 가지는 것으로 나타났다. 이러한 연구결과는 경쟁적인 고용사회에서 경력만족 및 고용가능성과 같은 주관적 경력성공을 높이기 위해서는 개인의 주도적인 경력계획이 필요함을 시사한다. 또한 경력계획을 통해 현재의 조직과 직무에 좀 더 만족하며 주관적 경력성공을 충족시킬 수 있음을 알 수 있다. 조직차원에서도 조직구성원들의 주관적 경력성공을 위해서는 개인차원의 역할뿐만 아니라 구성원들이 조직 및 직무적합성을 더욱 높게 인식할 수 있도록 개인의 경력계획을 반영한 경력개발프로그램과 직무순환제도가 개발될 수 있도록 전략을 강구해야 할 것이다.
