After the introduction stage, Korean mobile game market is approaching to the growing stage leading mobile contents market. The environment for the mobile contents business is getting better by the expansion of the 3G mobile networks and the enhancement of the mobile devices. In this research, at a content level, not a service level, market success factors of mobile games and the differences by genres and their changes over time were investigated through the analysis of the real market data of mobile games launched by a Korean mobile carrier. The most important factors for market success, especially for the genres of RPG/Tycoon/Simulation and Shooting/Action/Arcade, were found to be the 'design' factor and its effect turned to be getting stronger as time goes by after the launch. Consumers' purchase rate was actually higher for the mobile games of popular genres or in relation with socially popular subject matters. Also 'design' and 'creativity' factors which are related to the quality of contents, have gotten more important over time. One of the most interesting results was that there existed a "blue ocean" genres like Sports/Racing/Leisure which had a steady demand but not many competing games. In the analysis of the 'convenience' factor, one interesting implication for mobile game producers was that there exists a trade off between the ease of initial adoption and the steady sales of a mobile game.

The purpose of this study was to redefine and validate the motivational self-concept for child-care teachers. Based on related researches, items were remodified to be good enough to use for studying child-care teachers' motivational self-concept. Redefined items were analysed by factor analysis and validated by use of child-care teachers' professional recognition and their ego-resiliency. Researchers have garnered data from 321 child care teachers as convenience samples who are engaged in child care centers in Seoul and Kyunggi province by using questionnaire research methods. We have eliminated questions that are .40 below communality, questions by conducting exploratory factor analysis. As a result, 6 factors and 23 items were selected; 6 factors have indicated that it explained 77.12% of total variate motivational self-concept rating scale and ${\alpha}$ of Cronbach that of total items indicated acceptable level. After examining relevancy of child-care teachers' professional recognition and ego-resiliency to verify compliant feasibility of the motivational self-concept rating scale, the relation between motivational self-concept and professional recognition was .604(p<0.001) indicating significant static correlation and the relation between motivational self-concept and ego-resiliency was 4.456(p<0.01) indicating significant static correlation. Through this result, it is verified that motivational self-concept rating scale has compliant feasibility in professional recognition and ego-resiliency.

Although 'the International Ship Registration Act' has been enacted in Korea as of 1997, its effect is still in question to make shipowners and operators flag in or reflag because of insufficient incentives for them. Therefore, 'the Special Law for Jeju Free International City' has been established and the system of 'Special Ship Registration Zone' has also been enforced. Despite this, few studies were carried out to measure the relative importance of factors for Jeju International Ship Register yet. Against this backdrop, the purposes of this study are firstly, to investigate a relative importance of Jeju International Ship Registration System using AHP(Analytic Hierarchy Process) and secondly, to compare the characteristics of Flags of Convenience(FOC) with International Ship Register(ISR) which was adopted by several Far East Asia Countries(e.g., China, Hong Kong, Chinese Taipei and Japan). Moreover, this study aims to compare FOC with ISR in terms of shipping policy, ship management, and expenses and tax policy. In this paper, the factors were constructed with four high levels consisting of twenty one low levels to evaluate Jeju International Ship Register by utilizing Expert's brainstorming and AHP. According to the results, it is critical to expand the exemption and tax-related expenses, and also manage foreign-related systems systemically. This study provides important implications to maintain the tonnage tax system for ships effectively as well as to intensify the competitiveness of Jeju International Ship Register System.

There have been relatively lots of studies on the relationships beteen port and city. And, most of the recent studies on the subject shows that the relationship between the two parties is weakening. The contributions of a port to the city economy such as convenience of logistics service utilization, cost reduction, creation of job opportunities and value added production etc. are diminishing, whereas negative effects of port such as environmental effects, limitation of waterfront activities etc. have been increasing. On the other hand, port logistics service demand from city economy is decreasing. As for Busan city, the trend of major economic indicators and growth factor analysis results show that there is hardly any relationships between the development of transportation industry(including port logistics) and the regional economy. Especially, it is identified that most regional industry sectors excluding transportation industry failed to secure competitive advantage. Accordingly, it can be concluded that Busan city economy fails to take advantage of advanced transportation industry sector, which supports overall economic activities. On the other hand, it can be a problem for enhancement of port-city relationships that related and supporting industries of transportation industry such as information and communication industry, financial and insurance industry, and processing and assembling manufacture industry fail to secure competitive advantage in Busan city.

The South Korean Ministry of Land, Infrastructure, and Transport designated seven automated driving test beds required to evaluate vehicle performance every year for the expansion of mobility services based on automated driving. As a fundamental study, we suggested a necessary example of evaluating the performance with a satisfaction survey for the services before the evaluation. First, we surveyed the perception of automated driving services of users and the public in Sejong-si, South Korea. The survey showed that the users had a higher level of awareness of automated driving technology and intention to use it than the public. Second, the satisfaction survey was conducted on demand-responsive public transportation and automated driving service users. Notably, using the Wilcoxon Rank Sum Test, among the non-parametric statistical analysis methods, we found that safety-related factors affected the overall satisfaction of users of automated driving services. On the other hand, in the case of the demand-responsive public transportation service users, factors related to service convenience affected overall satisfaction. Hence, the results of these surveys are expected to be used as basic data and guidelines to improve the quality of automated driving services and policy establishment.

Much of a person's energy is spent in the effort of becoming a productive member of to-day's complex society. This activity may cause tension, and chronic unrelieved tension is an influential factor in blood pressure elevation. The problem of this study was to identify manifest needs and self-actualization of patients with essential hypertension, and to analyse and compare their manifest needs and selt-actualization with the selected general characteristics of We, sex, religion, occupation and level of education with a control group of patients with normal blood pressure readings. The purpose was to contribute to the planning of nursing interventions toward reducing the impact of complex psycho-somatic factors on the anxiety of patients with essential hypertension. The instruments used included selected items from the Edwards (1959) Personal Preference Schedule (EPPS) as adapted by Hwang (1965) and from the Personal Orientation Inventory (POI) (Shostrom 1964, 1974) adapted by Kim and Lee (1977) to measure manifest needs and self-actualization. The convenience sample was chosen from 149 persons who presented themselves for general physical examinations at Ewha University Medical Centre and 41 patients diagnosed with essential hypertension at three general hospitals in Seoul during June 1 and August 31, 1977. Forty-nine persons from the Ewha group with blood-pressure readings exceeding 150/90 were added to the experimental group. Data were analysed by the S.P.S.S. computer programme using t-test and tests for statistical significance. Statistically significant findings were as follows: A. Blood Pressure and Manifest Needs. 1. with the exception of Autonomy, patients with hypertension had significantly high scores on all variables Abasement, Achievement, Affiliation, Aggression, Dominance, Emotionality, Exhibitionism and Sex. 2. When mean scores of normal persons were compared by age groups, normal persons had higher scores in the following order on Abasement (50's, 40's, 20's, 30's), Achievement (50's, 30's, 40's, 20's), Affiliation (50's, 40's, 30's, 20's), Dominance (50's, 40's, 40's, 20's) and Exhibitionism (30's, 50's, 40's, 20's). In each case, there was a significant difference between the first and last age group scores. 3. When the mean scores of normal persons were compared by sex, normal men had higher scores than women on Achievement, Affiliation, Aggression, Dominance, Exhibitionism and Sex. Male patients had higher scores than female patients on Achievement, Dominance, Exhibitionism and Sex, but female patients scored higher in Emotionality. 4. Normal persons had higher scores related to religion in the following order on Achievement (Buddhism, no religion, Christianity). Hyper tensive patients had higher scores on. Exhibitionism (no religion, Christianity, Buddhism). 5. Normal persons had higher scores related to occupation in the following order on Achievement and Exhibitionism (unemployed, office workers, teachless, businessmen), Emotionality (office workers, unemployed, businessmen, teacher) and Sex (office workers, unemployed, teachers, businessmen). Hypertensive patients had higher scores on Achievement and Aggression (teachers, businessmen, office worker, unemployed), Dominance and Exhibitionism (businessmen, teacher, of ace workers, unemployed) and Sex (teachers, office worker, businessmen, unemployed). 6. Normal persons had higher scores related to level of edification in the following order on Abasement, Emotionality and Autonomy (secondary school graduation, university). Hypertensive patients had higher scores on Abasement (no education, primary, university, secondary), Achievement (no education, secondary, university, primary) , Dominance (university, no education, secondary, primary), Exhibitionism (university, secondary, no education, primary), and Sex (university, secondary, primary, no education). B. Blood Pressure and Self_Actualization 1, Patients with hypertension had significantly lower scores on all variables. 2. Normal persons had higher scores related to age groups in the following order on Existentiality (20's, 30's, 40's, 50's). Hypertensive patients showed no significantly different scores. 3. Normal women had higher scores than men on Time Competence. Normal men had higher scores on Feeling Reactivity. Male patients had higher scores than women on Self-Actualizing Value and Self-Regard. 4. Normal persons ha 1 higher scores related to religion on spontaneity (Buddhism, no religion, Christianity). Hypertensive patients had higher scores on Time Competence and Nature of Man (Buddhism, Christianity, no religion). 5. Normal persons had higher scores related to occupation in the following order on Existentiality (teachers, office workers, businessmen, unemployed) and Self-Regard (unemployed, office workers, teachers, businessmen). Hypertensive patients showed no significantly different scores. 6. Normal persons had higher scores related to level of education in the following order on Existentiality and Self-Acceptance (university, secondary). Hypertensive patients had higher scores on inner-Director (university, secondary, no education, primary) and Existentiality (university, secondary, primary, no education). Recommendations for nursing interventions with hypertensive patients with emotional problems or low self-actualization were made. 1. The nurse should encourage the patient through her interactions with other members of the medical team to accept counselling and health education. 2. Through her therapeutic interpersonal relationships with the patient, the nurse should help him discover the causes of his emotional tension. 3. Through her health teaching with the family, the nurse should encourage them to participate with the medical team in the patient's therapeutic plan and in providing him with the minimum possible emotional support. 4. Through frequent counselling with the obsessive-thinking and inflexible patient, the nurse should reevaluate the patient's behaviour and her interventions. 5. Seriously ill patients should be given needed reeducation by members of the professional medical team.

The objectives of this study are to provide the food market of internet shopping malls with effective marketing data, to provide basic data for the development of related fields of the study, and ultimately to increase the satisfaction of food consumers of internet shopping malls. To achieve the object of this research, a cluster analysis of the research subjects was carried out based on the following 5 factors of food purchasing attribute that had been deduced by a factor analysis by the types of food purchasers: quality characteristics, informativity, convenience, price and diversity. According to the result of the cluster analysis, the research subjects were classified into the 2 clusters of diversity and informativity. The deduced 2 clusters, together with age and occupation among general characteristics, were used as independent variables to find out food purchasing behaviors and satisfaction at internet shopping malls. The results are as follows: Regarding the frequency of food purchasing experiences at internet shopping malls according to occupation, the highest frequency was shown by those involved in service, sales and self-employed businesses; whereas regarding the frequency according to age, those in their 30s and 40s showed the highest frequency. The total amount of money spent on food purchasing for 1 year at internet shopping malls was shown to increase as age increased. The frequency of the purchasing experiences of agricultural products and fish products was shown to be higher as age increased. However, overall purchase satisfaction was highest among those in their 30s, while lowest among those in their 40s. Regarding satisfaction by the types of food purchased via internet shopping malls, satisfaction was relatively higher with common foods and functional foods, while lower with fish products. Taken together, it was concluded that purchasing behaviors at internet food shopping malls, such as the frequency of purchasing experiences and purchase amount, varied depending on age rather than purchasing attribute. Accordingly, in order to vitalize internet food shopping malls, it would be necessary to provide customized food shopping information for individual age groups.

For the past 10 years, the socioeconomic status of our country was markedly improved. Accordingly, our foodintake patterns and other alt parts are preparing to blance with developed countries. Especially, be westernizing or improving our foodintake patterns, we intake much fat diet(animal food) while our physical activities decrease and alcohol consumtion's population, smoking population gradually increase. For such reasons, the population of obese tendency and cardiovascular diseases are increased. According to recent reports, among all death causes in our country, cardiovascular diseases(hypertension, hypertensive cardiovascular diseases, ischemic heart diseases) occupyd top rank, we know. I(the author) studied the inter-relation between serum cholesterol level which is the important factor of the cardiovascular diseases and essential hypertension liver diseases, hyperglycemia, some cardiac problems which are main decline causes in life insurance's medical assessment, and body weight distribution. Studied samples were selected on 4,313 cases(male; 1,791, female; 2,522) who were tested liver function test from June, 11th, 1980 to Dec., 31st, 1983 on our medical department's laboratory. I selected two groups in those cases: one group was serum cholesterol level 180mg/dl over(11% of whole LFT examed cases: No=502 cases), the other group was serum cholesterol level 120-160mg/dl(No= 502 cases). For convenience, the group of serum cholesterol level 180mg/dl over was "A" the other group was "B", I described. All examed persons of LFT were resident m Tae-Jon city in that time. On the result, 1) Decline rate is 10.5% on the "A" group, 5.9% on the "B" group. "A" group reveals 1.8 times higher than "B" group. 2) On decline causes, Essential hypertension is 4.0 times higher on the "A" group than "B", liver function's abnormalities are 2.0 times higher on "A" group than "B" and other diseases are same on "A" and "B". On the "A" group, essential hypertension is considerably higher than "B" group. 3) On the body weight distribution, the cases of 70kg(B.W.) over is 19.7% on "A", 10.6% on "B" group. Obese tendency is 1.8 folds higher on "A" group than "B" group. Studing the result, we find high serum cholesterol concentration is closely related with essential hypertension, obese tendency and liver function's abnormalities on the life insurance's medical examination part, also. On the future, we will more carefully consider the serum cholesterol concentration on our medical examnination and assessment of life insurance, I think.

This study sought to figure out women's functional status after childbirth under the Sanhujori. Functioal status was defined as the women's readiness to assume infant care responsibilities and resume her usual activities including household, social and community, self-care and occupational activity. A convenience sample of 211 women who are in the postpartal period of the range from 1 week to 3 months above and residing in Seoul. Korea was studied from January, 1997 to December, 1998 for two years. Mean age of respondents was 29.9 years and mean of the present postpartal period was 7.5 weeks. The present postpartal period was of 5-8 weeks 26.5%, 3-4weeks 26.1%, 9-12 week 23.7% and below 2 weeks 7.1%, 32.7% of women had a job and the mean period of return to job was 2.76 weeks. During Sanhujori the non professional care giver was family members from women's maiden home 73.5% and only 2% of husband. The period women needed for the recovery from now was 5.39 weeks and it means that women need 12.9weeks for recovery after childbirth. For the present subjective health status after childbirth, bad was 20.2%, good 18.3 and average 61.5% and for the recovery status, completely recovered 29.5%, slightly 61.8% and rarely 8.7%. The mean of functional status at the 7.5weeks was baby care activity 3.65, household 2.57, self-care 2.46, occupational 2.44 and social 1.53 in rank. Except baby care the functional status was generally low or very low. The related factors to the functional status were the period and subjective evaluation of Sanhujori women experienced, the present period of postpartum, and subjective feeling of recovery. This result strongly reflects the effects of Sanhujori culture and Sanhujori per se on women's postpartal life including functional status and reconfirmed the relationship between health status and the experience of Sanhujori after delivery as the previous findings from various study showed. It provides a challenge to the professional care givers to research further on the effects of Sanhujori on the health status, health recovery after abortion or delivery from the various aspects through the cross-sectional and longitudinal research for the refinement of the reality of Sanhujori not only as cultural phenomenon but as an inseparable factor influencing in women's postpartal healthy adaptation and for the appropriateness of intervention and quality of care for desirable health outcome.
