The purpose of this study was to develop the framework of community-based home care nursing delivery system, and to demonstrate and evaluate the efficiency of it. The study was carned out over a period of 3years from September 1996 to August 1999. The researchers developed Standards for operations, this was all aimed toward a home care recording system, and an assessment intervention algorithm for various diseases quality control and standardization. In the center, 185 patients enrolled, and of the enrollments cerebrovascular disorder and cancer were the most prevailment diseases. Also, a home care nursing activity classification was developed in six domains. Those domains were assessment, medication, treatment, education and consultation, emotional care, and referral or follow-up care. Ten sub-domains were divided according to the systematic needs. Among these nursing activities, treatment, assessment, and education and consultation were frequently performed. In sub-domain classification, skin integrity, respiration, circulation, and immobility related care were provided most frequently. The cost of home care nursing per visit was also suggested. The cost include direct and indirect nursing care, management, and transportation cost. Also, the researchers tried to overcome the limitations of hospital-based home care to provide more accessible, efficient, safe, and stable home care nursing. Therefore, clients were referred from other patients, families, public health care centers, industries, and even hospitals. As a result of this study, several limitations of operation were found. First, it was difficult to manage and communicate with doctor in the emergency situations. Second, there was too much time spent for transportation. This was because they are only five nurses, who cover all of the areas of Seoul and nearby cities. Third, preparation for special care of home care nurses was lacking. Fourth, criteria for the termination of care and the frequency of home visits were ambiguous. Finally, interconnection with home care machinery company was so yely needed. New paragraphs' strategies for solving these problems were suggested. This study will be the basis of community-based home care nursing, and the computerized information delivery system for home care nursing in Korea.

Objective : The purpose of this study was to analyze the foot-pressure distribution of 2D(2 dimensional form) & 3D(3 dimensional form; a customized arch-fit for posture correction) insoles for assessing their biomechanical functionality. Background : Recently there has been increased interest in both foot health and foot pain patients. Analysis of the plantar pressure was often used to solve the problems of the foot displayed by such people as rheumatoid arthritis patients. Method : Subjects who participated in this study were 17 female university students who had no previous injury experience in lower limbs and a normal gait pattern. The shoe size of all subjects was 240 mm. Two models of insoles of 2D(typical flat insole - 2 dimensional form) and 3D(special production - 3 dimensional form) were selected for the test. Using the Pedar-X system and Pedar-X insoles, 4.0 km/h of walking speed, and a compilation of 50 steps walking stages were used to analyze foot-pressure distribution. Results : Results of the foot-pressure distribution and biomechanical functionality on each insole were as follows; analyses of mean plantar pressure, maximum plantar pressure, maximum vertical GRF, and plantar pressure curve shape all showed overall low plantar pressure and GRF. Conclusion : This can be evaluated as an excellent insole for low levels on the plantar pressure and GRF. Therefore, it is possible to conclude that according to this analysis the 3D Customized Arch-fit Insole was better than 2D insole on the basis of these criteria.

We study the optimal policy of the contracual arrangement in raising the debt-to-equity ratio for oil, gas and mining project finance deals. We investigate the impact of the optimal contractual relationship between counterparties on the soundness of projects, differing in output price volatility and country risk. Key findings are: first, the existence of EPC sponsors and off-takers generally raises the debt-to-equity ratio. In particular, EPC sponsors and off-taking sponsors jointly mitigate the credit risk caused by counntry risk. Seocond, off-taking and EPC contracts jointly help mitigate the credit risk caused by the country risk, rather than the price volatility. Indeed, the contractual structure raises the debt-to-equity ratio.

Purpose - Although various studies have been conducted on the stress of service employees, there are still lack of studies regarding job stress and job satisfaction of call center workers. Especially there are quite few studies on the job stress according to employment type. This study focused on job stress and job satisfaction for call center employees and the correlation between the two factors and aimed to provide basic materials for seeking for the plans to reduce job stress and improve job satisfaction. Research design, data, and methodology - Frequency, percentage, and mean value were calculated through descriptive statistics in order to find out demographic characteristics, level of job stress, and job satisfaction. Differences in job stress according to employment type were calculated by using one-way ANOVA. Correlation between job stress and job satisfaction were identified through empirical analysis with Pearson's correlation coefficient. 150 materials were used for final analysis. The collected materials were analyzed to get statistics by using SPSS 20. Results - First, as for the job stress of call center workers, overall mean value was 2.54 in 4-point scales. Among the six sub-factors, job demands had the highest score, which was 2.67. Second, as for the job stress according to employment type, others showed higher score than mean value followed by contract job and full-time job in that order, in terms of job insecurity and organizational system. In terms of inappropriate remuneration, contract job showed higher score than mean value followed by others and full-time job. Third, as for the satisfaction with job, the mean value was 2.37 in 4-point scale and "very much satisfied" was only 3.3%. Lastly, in terms of job stress and job satisfaction, all sub-factors except for job demands showed significant correlation. The more job stress increased, the more job satisfaction decreased. Conclusions - First, as a result of analyzing job stress according to the employment type of call center workers, job stress increased more when the employment type was not full-time. Therefore, it was assumed that self-rescue efforts should be followed for effective employment management of call center business where contract employment takes most part as well as efforts to transfer them to full-time job. Second, decrease in job satisfaction of call center workers may affect the performance of an organization as well as service quality of the company providing the service. Therefore, various supports are required to decrease job stress and increase job satisfaction for call center workers through the expansion of rest area or break time. Third, I could recognize that there were lack of academic research on call center business in the whole service industry. Therefore, further research should be conducted more actively in the future. In particular, this study has special significance in the aspect that there were few studies on the job stress of call center workers according to employment type.

Purpose - This study analyzed how image affects customer trust and satisfaction in the online shopping mall market, which is becoming more competitive; future implications for customer management in online shopping malls were presented. Consumers visit and prefer a few shopping mall sites instead of many sites. Consumers do not visit sites that cannot provide trust and satisfaction. Therefore, establishing trust and satisfaction with differentiated image is essential for survival and growth. Specifically analyzing company image, shop image, and brand image, I studied how symbolic image, functional image, and empirical image affect satisfaction mediated by trust in the online shopping malls of hypermarket retailers. Research design, data, and methodology - To investigate the relationship between image and satisfaction of big box retailers' shopping malls in the online market, the study is based on analyzed data from questionnaires involving advanced research. From May 1st to 20th in the year 2014, a questionnaire survey targeting university students using big box retailers' shopping malls in Seoul was conducted. A total of 282 questionnaires were conducted, and 276 questionnaires were used for empirical analysis, excluding invalid data. Using the SPSS 21.0 statistics package, factor analysis and regression analysis were implemented, and effects of image on trust and satisfaction were presented. Results - First, symbolic image can affect satisfaction with only trust. Among 3 image factors, symbolic image exerts the most influence on trust; trust is important in coupling the medium to satisfaction. Second, functional image and empirical image affect satisfaction directly and indirectly with trust. Conclusions - As I classified the image of hyper market retailers' online shopping malls into symbolic, functional, and empirical image, I analyzed the effects of image on trust and satisfaction empirically. The results of the study and strategic implications are as follows. First, symbolic image can affect satisfaction with only trust. Among 3 image factors, symbolic image exerts the most influence on trust; trust is important in coupling the medium to satisfaction. The establishment of a distinctive symbolic image, such as the online shopping mall's loyalty, level of awareness, and special service, is needed. With the establishment of symbolic image, trust and satisfaction could be improved. Second, functional image and empirical image affect satisfaction directly and indirectly with trust. Especially, as functional image affects trust more than empirical image, setting and implementing a strategy for empirical image based on the right price, service, and convenience could raise trust and satisfaction. Empirical image affects trust and satisfaction substantially. Even though empirical image's influence on trust is lower than that of other three image factors, empirical image's influence on satisfaction is higher than symbolic image. Therefore, it requires a strategy for providing joyful use, and information research functions and distinctive use experience are important to improve satisfaction. This study analyzed image characteristics of hyper-market retailers' online shopping malls in the fast-growing online market; future strategic implications were presented.

Today, the consumer is more careful in buying goods, invests more time in collecting relevant information to avoid any potential danger, and restricts from potential impulse buying. To react this consumer's carefulness, the seafood brands provide much information including the origin labeling system, the traceability, the food's safety & hygiene. Also the branding by region or company is pursued. Like that, a seafood brand's importance is increased, but there lack few researches dealing how current consumer's attitude influences on real purchase behavior, and how the attitude works consumer purchase decision. Therefore, this study researched the brand's influence on the consumer's attitude and purchase intention. For this purpose, this study targeted the salty mackerel and the dried yellow corvina because they are already branded and sold in some popularity, and researched how a brand's popularity, its image, and its recognized quality could effect on the consumer's attitude and purchase intention. As the result, it was appeared that a seafood brand's popularity didn't directly effect on the consumer's purchase intention, but indirectly influenced through the consumer's attitude as a parameter. From this result, improving a seafood brand's popularity needs some time to form the consumer's positive attitude and to lead to consumer purchase intention of seafood brand. So, it is thought that various promotion activities for seafood consumption must be continually performed rather than some temporary special events. Consumers showed more positive attitude on familiar seafood based on a product's original place and the freshness. Also they had better feeling about some seafood with their speciality images rather than the same kinds of products produced in other regions. This attitude temporarily led to purchase intention. Therefore, it is important that the branding strategy development should start from some seafood familiar to us in traditional food culture and food habit, but should delivery the reliance and the freshness in accurately indicating their origins, and should emphasize their differences as specialities. Consumers showed some positive attitudes on the seafood featuring the hygiene, the safety, continual good quality, and their attitudes led to their purchase intentions in temporary. The seafood product reflecting these results the best is the marketing activities on some Andong salty mackerel products acquired HACCP certification. it is thought that a seafood's branding strategy should be established on distinctive branding strategies using reliable certification mark like HACCP based on the hygiene, the safety, and the quality.

As the height and beam span of buildings built in the construction market increase, increasingly higher quality is being required of the construction materials. In response to this trend, 800MPa tensile strength class steel was developed in domestic company. Currently, experiments applying flexural member, compression member, and connections are continuously conducted, but a design guideline for high strength steel has yet to be established. Among those construction materials, for the high strength steel beam-to-column connections, the evaluation of implementing ductile connections for the high strength steel beam-to-column connections is producing pessimistic results and the number of related researches is inadequate because of the high yield ratio, which is the characteristic of high strength steel. This study on implementation of ductile connections made of high strength steel was conducted using the connection detail as the variable, for the purpose of enhancing the deformation capacity of high strength steel beam-to-column connections. Cyclic loading test and nonlinear finite element analysis were conducted with full-scale mock-up connection models with the applied connection details. As a result, the structural performance of high-strength steel beam-to-column connection with presented detail was contented with demand of Special Moment Frames of KBC standard.

The purpose of this study was to develop the framework of community-based home care nursing delivery system, and to examine the validity of it. For these, home care nursing study team of College of Nursing, Seoul National University has studied home care nursing system since September, 1996, and has operated home care center since August, 1997. This study has been supported by the Korean Sience Foundation. We organized Committee of rules, and Clinical specialist consultant group for more efficient running of the home care center. In nursing station, research assistant controlled general work, and 5 home care nurses were hired for home visiting. We developed the Standards for operations, that included criteria for clients, central supply system of nursing materials, central management of nursing care cost, advertisement, patient referral system, and so forth. In our center, 108 patients enrolled, and neurologic disorders including cerebrovascular accident, and cancer were the most prevailing diseases. We tried to overcome the limitations of hopital -based home care, and to provide more accessible, efficient, safe, and stable home care nursing. Therefore, we were referred clients from patients and families, public health care center, industries, as well as from hospitals. Meanwhile, we developed home care recording system and assessment-intervention algorithm for various diseases for quality control and standardization. Also, we did continuing education, and tried to detect problems and to find solutions by regular meeting between the committee of rules and home care nurses. As the results of this study, several limitations of operation were found. First, it was difficult to manage and communicate with the doctor in the emergency situation, Second, we spent too much time for trasnsportation, because only five nurses covered all areas of Seoul and nearby cities. Third, preparation for special care of home care nurses were lacked. Forth, criteria for termination of care and frequency of home visit were ambiguous. Fifth, some difficulties were found in retrospective payment system. And finally, interconnection with home care machinery company were needed. Strategies for solving these problems were suggested.

The purpose of this study was to analyze and compare the effects of exercise science of shoes for Aged' health promotion. Kinematic and kinetic data were collected using cinematography and the Zebris system (Zebris Emed Sensor Platform, GR-DVL9800) to analyze pressure of foot and ground reaction force. Subjects recruited were 20 healthy elderly men. They walked at 1.36m/sec velocity wearing type A (domestic), type B (foreign) and walking shoes (A company). One-way ANOVA was used to analyze statistics. The results were as following: no significant differences were observed in gait variables among the three groups (p<0.05). There was a significant difference in max pronation angle of heels examined among the three groups (p<0.05). There were no significant differences in kinetic variables (ground reaction force and max pressure) among the three groups (p<0.05). A physiology study was performed to analyze the effects of walking with shoes with silver added to them on percent body fat, resting metabolic rate and energy expenditure. Sixty adults males were recruited from the public health center. They were divided into four groups. C: control group (n=20), EY: elderly Y group (n=20), and EO: elderly O group (n=20). The results of this study were as follows: percent body fat was decreased following each exercise period, however, not all the groups showed a significant difference. The change of resting metabolic rate was significantly increased in HI (high intensity) and LI (low intensity) periods in the C and EY groups. However, there was no significant difference in the EO group. The mean energy expenditure during and after exercise were significantly lowered in all periods compared to the control group.

Globally, the baby boomer generation is economically retired, and the MZ generation is emerging as a new economic force. This study demonstrated the effect of service quality on user satisfaction and customer loyalty for IT services, and checked whether it had a moderating effect on the MZ generation's perception of service quality and its effect on user satisfaction. In addition, we tried to find implications for service satisfaction of the MZ generation. For this purpose, valid responses were obtained from 496 members of companies receiving IT services from Company A. then, a hierarchical regression analysis were performed to verify the hypothesis. As a result of the analysis, the influence relationship between service quality, user satisfaction, and customer loyalty was confirmed, similar to the results of previous studies, and it was confirmed that the negative moderating effect of lower perception of user satisfaction through interaction. Therefore, it can be suggested that there is a need to develop a new digital-based service that can share and sympathize with special experiences, consumption values and beliefs. In the future, if research is conducted on a variety of consumers, it will be possible to more accurately explore the service perception of the MZ generation.
