  • The purpose of this study was to evaluate the Quality characteristics, and was conducted to develope consumer preference of the frozen ready prepared eels by cooking method between 100 Korean (male 48, female 52) and 105 Japanese (male 43, female 62) who visited Korea. The consumers' responses about frozen ready prepared eels were measured on 9 point likert scale. In the preference test of cooking method for ready prepared eel, the Japanese and Korean preferred gas grill products in conger eel. Charcoal grill for Anguilla japonica products was estimated the most preferred cooking method by Japanese. In comparison between Japanese and Korean, Korean preferred more gas grill products than charcoal grill in Anguillajaponica products. The results for this factor were very significantly different in relation to appearance and overall acceptance of sensory characteristics (p<0.0l). The steaming products was estimated to be more delicious by Japanese than Korean. The results for this steaming products were very significantly different in evaluation of appearance, taste and overall acceptability between Japanese and Korean (p<0.05 or p<0.0l). In the domestic consumer test, the overall acceptability of eel product with ginseng and pine mushroom were 6.84 and 5.56 respectively. In the Japanese consumer test, the overall acceptability of eel product with ginseng and pine mushroom were 5.62 and 6.49 respectively. Consequently, Korea consumer preferred gas grill method for both conger eel and Anguilla japonica products added by ginseng flavor in sauce. Japanese preferred gas grill method for conger eel, charcoal grill method for Anguilla jap on ica added by pine mushroom flavor in sauce. Therefore, it is needed to study for the development of conger eel's sauce and cooking method proper to preference of Korean and Japanese in foodservice operations.

  • Two kinds of eddy current probes are mainly used to perform the steam generator tube integrity assesment in NPPs. The first one is the bobbin probe using for inspection of volumetric defect like a fretting wear. The second one is the rotating probe using for inspection of non-volumetric defect like a crack. The eddy current probe is one of the essential components which consist of the whole eddy current examination system, and provides a decisive data for the tube integrity in accordance with acceptance criteria described in specific procedures. The design of ECT probe is especially important to improve examination results because the quality of acquired ECT data is depended on the probe design characteristics, such as coil geometry, electrical properties, operation frequency. In this study, it is analyzed that the coil winding number of differential bobbin probe affects the electrical properties of the probe. Eddy current bobbin probes for the steam generator tubes in NPPs are designed and fabricated according to the results. Experiment shows that the change in coil winding number has much effects on the optimum inspection frequency determined by the tube geometry and material. Therefore, the coil winding number in bobbin probe is very important in the probe design. In this study, a basis of the coil winding number for the eddy current bobbin probe design for steam generator tubes in NPPs is established.

  • Social changes due to ICT like Big Data, IoT, Cloud and Mobile is progressing rapidly. Now, we get out of the old-fashioned frame was measured at the level of the information society through the introduction of PC, Internet speed and Internet subscribers etc and there is a need for a new type of diagnostic information society framework. This study is the study for the framework established to diagnose and measure post-information society. The framework and indicators were chosen in accordance with the technological society coevolution theory and information society-related indicators presented from authoritative international organizations. Empirical results utilizing the indicators and framework developed in this study were as follows: First, the three sectors, six clusters (items), 25 nodes (indicators) that make up the information society showed that all strongly connected. Second, it was diagnosed as information society development (50.34%), technology-based expansion (25.03%) and ICT effect (24.63%) through a network analysis (ANP) for the measurement of importance of the information society. Third, the result of calculating the relative importance of the cluster and nodes showed us (1)social development potential (26.04%), (2)competitiveness (15.9%), (3)ICT literacy (15.5%) (4) (social)capital (24.3 %), (5)ICT acceptance(9.54%), (6)quality of life(8.7%). Consequently, We should take into account the effect of the economy and quality of life beyond ICT infrastructure-centric when we measure the post-information society. By applying the weighting we should performs a comparison between countries and we should diagnose the level of Korea and provide policy implications for the preparation of post-information society.

  • The effects of Curcuma extract Solomon's seal (Polygonatum odoratum var. pluriflorum), and maltodextrose on acute hepatotoxicity in Sprague-Dawley (SD) rats were investigated. Acute hepatotoxicity was induced by 0.5 mL of carbon tetrachloride ($CCl_4$) per kg of SD rats, which was injected to them before administration of Curcuma extract or both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures. SD rats dose with Curcuma extract of 4 mg or 40 mg per kg per day significantly (p<0.05) reduced the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALKP) after 7 days compared to the controls dose with water. Treatments of Curcuma extract with 4 mg per kg per day in SD rats significantly (p<0.05) reduced aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALKP) to 78.0%, 82.6%, and 76.3% after 7 days compared to the controls, respectively. The levels of AST and ALT in SD rats dose with both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures or either alone had no significantly different (p>0.05) compared to the controls. Treatments of Curcuma extract combined with Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures was 'liked more' to the sensory scores for odor and flayer compared to the controls. It was considered that Curcuma extract combined with both Solomon's seal (Polygonatum odoratum var. pluriflorum) and maltodextrose mixtures could be used to functional food for enhancement of health and consumer acceptance.

  • This purpose of this study was to use the meta-summary method to systematically integrate the findings of the heterogeneous qualitative research on the factors influencing the sexual identity formation process of lesbian, gay, and bisexual groups in Korea. The integrative investigation of the universal or unique factors affecting the identity formation of sexual minority is important to understand their internal experiences and support their psychological adaptation. Using a qualitative meta-summary, this study systematically identified and abbriviated the psychological and social factors that promote or impede the sexual identity acceptance and integration of LGB individuals. First, a total of 9 studies which were published in Korea up to 2021 were identified through the research database. The included studies were critically evaluated by using the Critical Appraisal Screening Programme tool. A total of 179 statements were extracted from the findings of each study and 34 abstracted statements were generated. The 34 abstracted statements were categorized into four groups, psychological factors that promote or impede sexual identity formation and social factors that promote or impede it. These four main categories and corresponding factors in each category were explained. The implications and limitations were also discussed.

  • The present research is aimed at to examine the relationships between wisdom and age, also between wisdom and its psychological adaptation among middle and elder adults in Korea. Moreover, using data on 240 middle-aged and elder adults, the relationship between different aspects of wisdom and aging well were not only examined, but also explored age differences of wisdom through adulthood. The major findings from the study are summarized as follows. first, the wisdom scores of middle-aged and elder adults were significantly higher than those of young adults. While 'cognitive competency' and 'positive life attitude' factors had no significant differences. It means that 'cognitive competency' and 'positive life attitude' wisdom could be stable across adulthood. However, 'moderation and balance' and 'sympathetic interpersonal relationship' wisdom of elders were significantly higher than those of young adults. second, in middle and elder adults, Wisdom was found to be positively related with life satisfaction, well-being, death acceptance, experiences of positive emotion, generativity, ego integration, and positive life review. while on the other hand, contrast wisdom to be negatively related with depression, fear of death, perceived stress and experiences of negative emotion. The results from the study were examined by ecological validity of wisdom. Accordingly, a number of limitations and implications of the research were acknowledged.

  • In this paper, an efficient call control procedure is presented for next generation wireless ATM networks and its performance is mathematically analyzed using the open queueing network. This procedure is based on a new scheme called as the cell clustering. When we use the cell clustering scheme, at the time that a mobile connection is admitted to the network, a virtual cell is constructed by choosing a group of neighboring base stations to which the call may probabilistically hand over and by assigning to the call a collection of virtual paths between the base stations. Within a microcell/picocell environment, it is seen that the cell clustering can support effectively a very high rate of handovers, provides very high system capacity, and guarantees a high degree of frequency reuse over the same geographical region without requiring the intervention of the network call control processor each time a handover occurs. But since mobiles, once admitted, are free to roam within the virtual cell, overload condition occurs in which the number of calls to be handled by one base station to exceed that cell site's capacity of radio channel. When an overload condition happens, the quality of service is abruptly degraded. We refer to this as the overload state and in order to quantify the degree of degradation we define two metrics, the probability of overload and the normalized average time spent in the overload state. By using the open network queueing model, we derive closed form expressions for the maximum number of calls that can be admitted into the virtual cell such that the two defined metrics are used as the acceptance criteria for call admission control.
