  • The purpose of this study were to investigate the job analysis questionnaire was mailed to 250 dietitians who are members of The Korean dietetic association practice group in self-operated foodservices(hereafter group A)and 250 dietitians who are employed in contracted foodservice companies(hereafter group B). Completed questionnaires were received from 285 dietitians(121 in self-operated, 164 in contracted) ; a response rate of 57%. Statistical data analysis was completed using the SAS/win packages for descriptive analysis, t-test, $x^2$-test, The results of this study can be summarized as follows. 1. The dietetic training or internship experiences were significantly different between the two sample group(p<.001), but the perceptions of needs for training or internship were not different between and they thought one to six month training would be needed for the job. 2. The question about the time needed in order to perform an expert job was answered significantly differently(p<.001) 3. Group A usually took part in obligatory continuing education and short-term training courses, and group B usually took part in obligatory continuing education and on-the-job trainings, respectively. However both group perceived all three types of educations would be needed for performing the job better. 4. As for the physical demands of the job, a certain degree of accuracy and dexterity for physical tasks and equipment operations was needed for the job. Concerning the mental demands, they answered that their job needs considerable creativity and judgement for planning and performing their tasks was needed. 5. As for responsibilities, group B's responsibilities were heavier than group A’s(p<.001) and need for confidentiality was also greater for group B than for group A(p<.001). 6. As for the supervising role differences, group A rarely received supervision from others and they were given directions only in essential situations, whereas group B was usually supervised when planning and performing their job and tasks, showing significant difference in positions between the two sample groups(p<.001). But each group supervised co-workers and employees in their department. 7. With regard to personal contact, both groups frequently contacted people in their department and other departments at the company and sometimes people outside the company. 8. Concerning the work environment, there were some risks and discomforts in the physical environment and there was no significant difference between the two sample groups.

  • Diabetes mellitus, a universal and prevalent chronic disease, is projected to be one of the most formidable worldwide health problems in the 21st century. For those living with diabetes, there is a need for self-care skills to manage a complex medical regimen. Self-efficacy which refers to one's belief in his/her capability to monitor and perform the daily activities required to manage diabetes has be found to be related to self-care. The concept of self-efficacy comes from social cognitive theory which maintains that cognitive mechanism mediate the performance of behavior. The literature cites several research studies which show a strong relationship between self-efficacy and self-care behavior. Meta-analysis is a technique that enables systematic review and quantitative integration of the results from multiple primary studies that are relevant to a particular research question. Therefore, this study was done using meta-analysis to quantitatively integrate the results of independent research studies to obtain numerical estimates of the overall effect of a self-efficacy with diabetic patient on self-care behaviors. The research proceeded in three stages : 1) literature search and retrieval of studies in which self-efficacy was related to self-care, 2) coding, and 3) calculation of mean effect size and data analysis. Seventeen studies which met the research criteria included study population of adults with diabetes, measures of self-care and measures of self-efficacy as a predictive variable. Computation of effect size was done on DSTAT which is a statistical computer program specifically designed for meta-analysis. To determine the effect of self-efficacy on self-care practice homogeneity tests were conducted. Pooled effect size estimates, to determine the best subvariable for composite variables, metabolic control variables and component of self-efficacy and self-care, indicated that the effect of self-efficacy composite on self-care composite was moderate to large. The weighted mean effect size of self-efficacy composite and self-care composite were +.76 and the confidence interval was from +.66 to +.86 with the number of subjects being 1,545. The total for this meta-analysis result showed that the weighted mean effect sizes ranged from +.70 to +1.81 which indicates a large effect. But since reliabilities of the instruments in the primary studies were low or not stated, caution must be applied in unconditionally accepting the results from these effect sizes. Meta-analysis is a useful took for clarifying the status of knowledge development and guiding decision making about future research and this study confirmed that there is a relationship between self-efficacy and self-care in patients with diabetes. It, thus, provides support for nurses to promote self-efficacy in their patients. While most of the studies included in this meta-analysis used social cognitive theory as a framework for the study, some studies use Fishbein & Ajzen's attitude model as a model for active self-care. Future research is needed to more fully define the concept of self-care and to determine what it is that makes patients feel competent in their self-care activities. The results of this study showed that self-efficacy can promote self-care. Future research is needed with experimental design to determine nursing interventions that will increase self-efficacy.

  • The purpose of this paper is to examine atmospherical factors affecting user's satisfaction in natural park to answer the research question: what are the effects of atmosphere on user's satisfaction in natural parks(NP). After reviewing the literature, mechanism of NP, and use elements in NP, We constructed the conceptual framework and have formulated the hypothesis of this research. We had obtained data through a questionnaire, which surveyed 508 visitors at 6 of the 73 NP in Korea in 2001, based on stratified sampling method. We have analyzed the data using descriptive statistical methods, the mean difference test, Pearson's correlation analysis, and the multiple linear regression method. We found that 1) the five atmospheric variables, j.e., number of users(NOU), crowding, damage to park resources(DPR), and maintenance of park resources and facilities(MPRF), encounter level(EL) affecting user's satisfaction, have tuned out to be statistically significant at a five percent level. The direction of the relationship between user's satisfaction and MPRF, NOU, EL is the same as that of the dependent variable and the opposite of crowding, and BPR, 2) in bivariate analysis, the positive relationships between user's satisfaction and park resources, MPRF are fairly high and statistically significant. The higher the value of DPR, and crowing, the lower the degree of user's satisfaction, 3) in multivariate analysis, such variables as NOU, crowding, DPR, EL, and MPRF affecting user's satisfaction have been statistically significant at five percent level, and 4) the relative contribution of MPRF, park resources, park facilities, NOU, crowding, DPR, and size of activity space on user's satisfaction have been determined to have respectively 6.00, 4.78, 2.53, 1.83, 1.64, 1.59 and 2.03 times more important than that of EL. Among the atmospheric variables, MPRF is the most important at 1.26 times higher than that of park resources. The research results suggest that the development of devices for the increase in user's satisfaction and user management program based on the knowledge we have found, be recommended in the planning and development process of natural park. The approach adopted by this research is valid and useful for evaluation criteria of NP. It is recommended that more empirical studies by activity types, activity spaces, and seasons on atmospheric elements affecting user's satisfaction be performed in the future.

  • This study aimed to investigate the effects of learning with role-playing on student satisfaction and achievement regarding behavior management teaching in pediatric dentistry. 93 students were divided into 19 groups and randomly assigned to role-play as a doctor, patient, parent, assistant, or narrator. Their performances were evaluated by the instructor and the satisfaction survey was conducted. All participants took the written test and were asked to compare lecture and role-playing with regard to the effectiveness of learning. Statistical analysis was performed with Mann-Whitney U test, Independent T-test, and Kruskal-Wallis test. 68 students (73.1%) who believed that the role-playing was more helpful than lecture showed higher level of satisfaction than students who believed lecture was more helpful. But there were no differences in the tutor evaluation score and the written test scores. Participants in the patient management scenario showed higher level of descriptive question scores of the written test and tutor evaluation score than those who participate in the parent management scenario. There were no differences between the role groups. Role-playing may help students to become more interested and participatory in learning behavior management. The level of satisfaction may differ by the design and content of the scenario.

  • From the economic point of view the fishing port is the complex of installations on land, organized to serve the fishing fleet and its cargo, and is the main link in the production chain of all components of the fishing industry, with the aim of achieving the planned targets with the minimum cost. Fishing port investment decisions have had significant impact on the development aims of Korean fisheries. Fishing port investments in Korea are made mostly by public or semipublic port authorities. Such investments should be judged not purely on the basis of financial profitability but rather on the extent to which they serve the development aims of the fishing industry. This makes the economic appraisal process more complex and presents certain problems in correctly quantifying the economic costs and benefits of the fishing port projects. This study concentrates more on the theoretical economic appraisal models than on the purely financial aspects of fishing port investments and points out the difference between the two approaches. In the result, there is clearly an element of judgment as to whether or not a shadow price needs to be used in estimating economic benefits and costs. From this viewpoint, some attempts are made to provide definitions of the possible economic benefits and costs, and methods for estimating and evaluating them in Part III and IV. Especially queueing theory is applied in the calculation of economic benefits. When a project is contemplated and analysis shows it to Lave a positive NPV, one question that arises is whether it should be implemented now or delayed. In this paper, the first year rate of return method is regarded as a more concise way of solving the timing of investment, At the end of Part IV, risk analysis of fishing port investments is considered. It can be handled in a number of ways, ranging from informal judgment to complex statistical analyses involving large-scale computer models, This paper recommends that evaluators of fishing port investments use the sensitivity analysis indicating exactly how much NPV will change in response to a given change in an input variable, other things held constant. Decisions regarding the amount of capacity to provide must be made in fishing port investments. Providing too much service would involve excessive capital costs. On the other hand, not providing enough service capacity would cause the waiting line of fishing vessels to become excessively long at times. Therefore, in Part V, the optimal number of berths and berth productivity in fishing port are defined as follows: Minimize E(TC) = E(WC)+E(SC) The minimum of this function is the solution and that is the optimal number of berth and berth productivity in fishing port.

  • Generally a venture capital aims at investment and support Venture businesses that signifies a start-up which has high technologies but frailty of the economy so that raise fund from financial agencies at high risk rate, it has high risk but when the venture businesses launch into general orbit, the venture capital guarantee high-rate profits. Venture capital do not just provide risk capital but also takes a role as a mentor for continuous growth with total consulting service at business and technical management. Also it offers in-depth support to reform the supported enterprise in order to enhance the competitive. Venture capital receives attention for years as a principal agent to be promoted strategically at national level. Bio venture, a major concern of venture capital and one of core industries in Korea, is different from other industries because it needs long-term and large scale of investment. these factors bring about difficulties in an investment and growth. Therefore, it is very important to identify growth and profitability of start-ups and small and venture businesses with long-term appreciation above all other industries. This research analyze management results of bio venture businesses empirically by investment from venture capital. according to the results, bio venture businesses need huge capital and a long gap of time, henceforth, formation of model for growth is necessary with angel investing as well as venture capital. Since, there are not many listed bio venture businesses, significant statistical result would be limited. This research studied at only economic focus but further study need to examine a question from various angles.

  • The purpose of this study is to analyze customers' behavior in using word-of-mouth(WOM) information about Korean local food restaurants. The questionnaire developed for this study was distributed to 500 customers living in Jeonbuk area and a total of 455 copies (91.0%) were used for analysis. The statistical analysis was conducted using SPSS Win(12.0). The results were summarized as follows. The recommendation of people experienced'($M=3.57{\pm}1.24$) and 'word-of-mouth through people around'($M=3.52{\pm}1.20$) were major word-of-mouth information sources of Korean local foods; 'taste of food'($M=4.16{\pm}1.15$) and 'service quality'($M=3.79{\pm}1.11$) were important attributes in word-of-mouth information. In addition, to the question about the reasons for recommending the restaurant to the people around, the most people replied that 'flavor, nutrition and quality of local foods can be kept only in the specific location' ($3.53{\pm}1.08$), followed by 'to keep the memory of the visit to the areas in mind through local foods'($3.51{\pm}1.03$). These results showed that people usually recommend a restaurant based on the quality of the food itself or local characteristics. As a result, it is deemed that word-of-mouth effect is an important factor for the spread of Korean local foods.

  • Sustainable development brings many potential advantages to the society and environment. As such, many educational communities have concentrated on incorporating this concept into their educational programs for the K-12 classrooms. The K-12 technology educators have also exerted efforts to infuse the sustainable development concept into the K-12 national-curriculum level. The purpose of this study was to investigate the high school students' attitudes towards sustainable development. The study participants were 1,073 high school students from six high schools in Gyeonggi province. A self-reported instrument was used to obtain the students' demographic information and to come up with an attitudinal scale towards sustainable development. This study employed statistical ways of exploring the attitudinal level of the South Korean high school students and of describing the subcategories of the sustainable development. The findings described the high school students' attitudes towards sustainable development with regard to three components: (1) cognition of sustainable development; (2) practices in pursuit of sustainable development; and (3) perception of the education for sustainable development. The exploratory factor analysis supported three perspectives of the students' attitudes towards sustainable development. Also, the qualitative data collected and analyzed from the students' responses to the open-ended question posed to them indicated two domains of the students' cognition of and practices in pursuit of sustainable development. These findings were made on the bases of several recommendations regarding the research on and implementation of Education for Sustainable Development(ESD).

  • This research was conducted to develop an assessment measure of attitude toward engineering. Based upon related document research and case studies, we came up with operational definition and category of attitude toward engineering as well as questionnaires to assess. After consulting with specialists and studying on relevant documents, we changed some of the 60 questions developed in the first phase or added new ones. One hundred and nine students who major in engineering were questioned by the 40 questions selected in the second phase. Using SPSS 14.0K statistics program, various techniques were used including factor analysis, validity analysis and correlation analysis. And the level of significance of statistical verification was 0.05. The result is as follows: Based on fundamental aspect of the attitude, this research focused on 3 different variables: cognitive variable such as 'attitude toward engineering value', affective available such as 'general attitude toward engineering and attitude toward engineering study', Behavior available such as 'participation in engineering activity'. Therefore, as a subcategory, attitude toward engineering value is classified into value as study and job, social value and personal value, general attitude toward engineering and attitude toward engineering study are divided into self-concept, self-efficacy, awareness, interest and cooperation. Also, participation in engineering activity is classified into attitude toward engineering study. After applying this measurement to the field, we integrated self-concept into self-efficacy, omitting one independent factor in the question. Finally, through Verimax, we developed 'Instrument of Assessment the Attitude toward Engineering(IAAE)' which consists of 3 variables, 9 subcategories and 39 questions.
