This study set out to develop and evaluate an educational program for the Clothing Life of Home Economics through the theme-based integrated approach develop integrated thinking abilities for solving everyday problems. For those purposes, it selected a couple of themes in the area of Clothing Life toward which the theme-based integrated approach could be develop and evaluate an educational program. The developed program was applied and assessed in total 28 hours of field lessons given to eighth graders attending B Middle School in Busan Metropolitan City. The analysis stage involved an exploration into programs related to an integrated approach to other subjects; the design stage identification of program types; and the development stage theme selection according to the selection criteria. The previous studies were analyzed along with the Technology and Home Economics textbooks to select a theme. two themes "Clothing Management" and "Fabrics(Materials)" were selected after discussing with the students on the Messenger and with a group of experts. Then content was organized and composed around the themes by discussing connections with other subjects. There were three evaluation; one by experts, another through preliminary lessons, and the other through field lessons. Following the research procedure, a theme-based integrated program was developed for the two selected themes. It contained total 49 and 32 learning materials for "Clothing Management" and "Fabrics(Materials)," respectively. Those learning materials were comprised of experiments and practices according to the nature of the themes. Each program consisted of the goals, learning content, content organization chart, learning activities, and evaluation; learning activities experiences, practice and experiment activities, self-directed activities and problem-solving processes; and evaluations self-evaluation, teacher evaluation, peer evaluation, portfolio, and experiment reports. The program was assessed three times. The first and second evaluation results found that the program was well compatible with the current needs, was properly organized to give lessons through integration with other subjects, and continuously maintained the students' interest. They, however, requested that there should be detailed explanations about each part of the program content. In the third evaluation done by the students during field lessons, 60% of them said that the program was fun and its content was easy to understand, that they realized a theme could be connected to several other subjects, and that the program could be applied to actual life. The educational program through the theme-based integrated approach is significant in that it is an educational program for the area of Clothing Life and tries an integrated approach. It helped the students not only gather knowledge in an integrated manner, but put it to practical uses to solve various problems they faced in actual life by creatively changing integrated knowledge. The study will be hopefully used by many teachers so that the students solve problems based on the ability of integrating various knowledges organically.

In this paper, the e-grocery sector of the U.S. is used as an illustrative example of how to assess consumers' demands for customer relationship management and to investigate whether these demands coincide with effective Customer Relationship Management (CRM) strategies suggested by academic researchers and provided by practitioners. Surveys evaluating the perceived importance of CRM items were administered accordingly. The findings show that, overall, consumers' did not differ considerably to the experts. The results of descriptive analyses showed that academicians had a more closely in-lined view with consumers than did practitioners. Although not statistically significant, practitioners perceived loyalty programs to be more important than did consumers or academicians. This might suggest that loyalty programs are primarily serving as a way of data mining, and are thus failing to provide benefits to consumers. Overall, items related to technology deployment were perceived to be more important by practitioners than consumers or academicians.

The storage stability of the developed Formula of infant foods was investigated. The results are summarized as follows : When formula A and B were stored at room temperature and refrigeration temperature, there was no remarkable changes in consistency. In frozen state, formula A showed more stability in consistency than formula B and formula A could be stored for 6 months without problems due to retrogradation of starch. The heat treatment of both A and B resulted in the increase of a-value, while L-and b-value showed no such change. But from the 4th month at room temperature, and 5th to 6th month at refrigeration appeared an increase in a -value, hence the browning reaction, while frozen samples did not show noticeable changes in surface color. The heat treatment also caused an increase in POV on both formula. The extent of changes in POV during storage varied with storage temperatures and samples.

This study investigated the educational status, students' recognition, educational needs and degree of difficulty on the food and nutrition section of Technology Home economics subject in middle schools. It was carried out through questionnaires. The subjects were 503(boys; 246, girls; 257) middle school students in 3rd grade in the Daejeon area. The results were as follows. The students' preference for food and nutrition section was 58.5% of boys and 72.0% of girls. On the educational status of this section, The highest cooking frequency was once a year(52.3%), but 12.9% of students had never done cooking practice. Generally, practice education was not enough in subjected schools. The education of food and nutrition section was mainly conducted by lecture. For the behavioral change of students after learning this section, 'I can cook some simple foods' was the most(36.8%) than the other. The contents of high educational needs in this section were 'cooking foods' and ‘basic cooking methods'. A average degree of difficulty in this section was 2.89 points of the likert scale(1~5 point), particularly, 'change of food components by cooking' was the highest at 3.17 points of likert scale(1~5 point) in this degree. In relation to demographic background, the difficult degrees of this section were significantly higher than the other, when their parent's education was under middle school and their fathers' had no occupation. It suggests an increase in cooking frequency, complementing contents needed in life and using various audio-visual education aids are necessary for the education of food and nutrition section.

Some physicochemical properties of gamma-irradiated soybeans (0-20 kCy) were investigated. Proximate components, fatty acid compositions and minerals of the soybeans irradiated at 2.5 - 20 kGy shrived no difference from the nonirradiated control. Irradiation doses above 10 kGy and long term storage caused decrease in extractable phenols and phytate content, whereas increases in acid value and organic acid content. The total amino acids content of the soybeans irradiated up to 10 kGy was not changed as compared with the nonirradiated control. Sulfur-containing amino acids, however, were changed by 10 and 20 kGy irradiaton. Gamma irradiation and long term storage caused minor changes in the color attributes of soybeans. Hunter's 'L' (lightness) and 'b' (yellowness) values were decreased whereas 'a' (redness) value was increased with increasing dose levels and the elapse of the storage period.

Among many honeys, the buckwheat honey was the best one using for Yackwa(a Korean cookie). We made a substitute, similary syrups of buckwheat honey, and then we got the following conclusions through the case of the similar syrups. 1. The best syrups are A, B and C syrup. A syrup's composition rate was sugar (40%), corn-syrup (20%) and water (40%) before boiling for 10 minutes. B syrup's composition rate was water (40%), glucose (20%), corn-syrup (20%) and sugar (20%) before boiling for 15 minutes. C syrup's composition rate like B syrup's but boiled for 10 minutes. 2. The best syrups used for dough are A and B syrup. C syrup was good for soaking. When A syrup used for dough, we have to immediate soaking in A syrup after frying or soaking in C syrup an hour later after frying. When B syrup used for dough, we must soaking in C syrup an hour later after frying. 3. The rate of fat in the composition of buckwheat honey's, A syrup's and B syrup's Yackwa was 27.22%, 23.05%, 23.05% and 30.35%.

To study the effects of diets containing red Ginseng, rats were fed diets containing various amounts of red Ginseng for 10 weeks. The Ginseng diets were 600 mg of red Ginseng extract concentration, 1,200 mg of red Ginseng powder, 6,000 mg of red Ginseng tea, 3,000 mg of red Ginseng extract concentration, 6,000 mg of red Ginseng extract concentration, 12,000 mg of red Ginseng extract concentration per Kg of diet, and control. As results, growth rate, feed efficiency ratio, organ weight, and hematocrit value showed no statistically significant differences between red Ginseng fed animals and the controls. Serum cholesterol level and GPT were slightly lower in the experimental animals than those in the controls. These differences, however, were not statistically significant. Serum GOT activities for all experimental animals showed no statistically significant except for Group fed with 6,000 mg of red Ginseng extract concentration per Kg diet. This Group revealed significantly lower GOT activities than those of the controls statistically. No abnormalities of liver, spleen, and kidney were observed in the experimental animals.

Purpose - As ahigher-order ability, improvisational capability is often employed to help a firm cope with unexpected or unanticipated issues. In light of the severe global business challenges and turbulent environmental changes, this study aimed to explore whether home-based network ties could shape the influence of improvisational capability on international entrepreneurship, alongside investigating the boundary conditions of competitive turbulence in their moderating effects. Design/methodology - The sample for the international entrepreneurship sector was obtained from the Industry and Information Technology Department of Jiangsu. In September 2021, the questionnaires were sent to the targeted ventures and required the top managers to complete the survey by email or telephone. The final research sample comprised 113 international new ventures. To test the hypotheses, moderated hierarchical regression analysis was conducted. Findings - Our empirical results suggested that (1) unlike some previous literature, a positive effect of improvisational capability on the performance of international new ventures was not found; (2) home country-based networks (both political ties and business ties) are contingent factors that may partially stimulate the value creation of improvisational capability; and (3) in a highly competitive environment, the moderating role of business ties at home may become much stronger, however, the contingent role of political ties at home was not found. Originality/value - This study mainly concentrates on the two important types of home country-based networks, political and business ties at home, that may help international new ventures access strategic resources necessary for supporting the performance implications of improvisational capability. Thus, it extends the existing improvisational theory to encompass international entrepreneurship.

The purpose of this study was to develop practical problem focused teaching learning process plan for housing for the later life in order to apply it to the older stage of family planning section of Technology Home Economics in a highschool. Practical problem focused method was used for the teaching learning process plans of 3-session lessons according to the ADDIE model. The global practical problem was "What should I do to plan a safe and comfortable housing for the later life?" In the development stage, 53 teaching learning materials (44 students activity materials, 2 students' and 5 teacher' reading texts, and 2 moving pictures) were developed for 3-session lessons. The planes applied to the 5 classes, 150 students, in the freshmen of B highschool during April 20th-24th, 2009. The 5 point likert questionnaire were used to evaluate the 3-session lessons about 4 contents related aspects as well as the methods and effects of the lessons besides 2 open ended questions. The overall evaluation was very positive in all 6 aspects of the lessons. Some students wanted to learn more about universal design and aging related jobs. Those results showed that the practical problem focused teaching learning process plan for housing for the later life which this study developed would be appropriate to teach the older stage of family planning section related to housing and could be adjusted to the condition of each school and regions.

This study investigates the effect of high-skilled inventor emigration rate on growth rate of the country of origin (COO). Inventor emigrants represent the human capital that can generate highly innovative work. The social network they form spurs knowledge diffusion and technology transfer back to their COOs, which in turn affects innovation and growth in their home countries. We run dynamic panel estimation for 154 countries during 1990-2011, and empirically show that a positive and statistically significant effect exists for the interaction of inventor emigration and trade. The result indicates that the direct negative impact of the brain drain can be mitigated by the positive feedback effect generated by the high-skilled inventor emigrants abroad. When coupled with an active trade policy that reinforces growth, countries can partially recoup the direct effect of the human capital loss. We stress the importance of international trade for successful technology transfer to occur, and offer insights for policies that can utilize the benefits of the rich social network of their high-skilled emigrants.
