The purpose of this study was to investigate how menu quality, human ${\cdot}$ amenity service quality, perceived risk affected quality ${\cdot}$ price menu value, social ${\cdot}$ emotion menu value and how quality ${\cdot}$ price menu value and social ${\cdot}$ emotion menu value influenced satisfaction. Also this study investigated how satisfaction affected loyalty. The model was tested in hotel restaurants settings of five-star hotels using a sample of customers visiting and enjoying menus in Daegu metropolitan city and Gyeongju city. Empirical results confirmed that not only do menu quality and human ${\cdot}$ amenity service quality increase quality ${\cdot}$ price menu value and social ${\cdot}$ emotion menu value but that perceived risk reduces social ${\cdot}$ emotion menu value. It was also found that significant antecedents of satisfaction were quality ${\cdot}$ price menu value and social ${\cdot}$ emotion menu value. Also, loyalty was also found to be a significant consequences of satisfaction.

This study was conducted to determine the mixing conditions for Hibiscus syriacus L. chocolate depending on different addition ratios of Hibiscus syriacus L. and examine functionality in order to use Hibiscus syriacus L., which has excellent functionality and symbolizes Korea. To accomplish this, Hibiscus syriacus L. chocolate was manufactured by adding 0%, 2.5, 5, 7.5, and 10% of Hibiscus syriacus L. powder from the 'Samchulli' (Hibiscus syriacus 'Samchulli', which has reddish pink flower with red eye spot: SKK 14-2-72) variety to a coverture of white chocolate after which the antioxidant activity and quality characteristics were analyzed. As the amount of Hibiscus syriacus L. powder added to the chocolate increased, the chocolate color became darker, the pH decreased, and the sugar content and hardness increased. As a result of the sensory evaluation, the degree of preference increased as the amount of added Hibiscus syriacus L. powder increased to 7.5%. The degree of preference for color and flavor was the highest in the 5% added group, but the overall preference was 7.5% added chocolate. These findings demonstrate that adding Hibiscus syriacus L. powder to chocolate can increase chocolate functionality and preference and that there is a high possibility of Hibiscus syriacus L. chocolate development.

본 논문은 생산성 향상과 품질 개선이라는 조직 성과를 높이는 데 직무 만족과 상호작용하는 조직 커뮤니케이션과 조직 문화, 그리고 경영진에 대한 신뢰의 역할과 기능에 대해서 추적하였다. 창원지역 기계금속 업종 근로자로부터 표집된 설문 자료를 토대로 하여 연구 가설을 검증한 결과 세 가지 조직 환경 변인과 직무 만족이 조직 성과에 미치는 직접적 효과는 미미하였으나 의미 있는 상호작용 효과를 확인하였다. 검증된 상호작용 효과를 살펴보면 대체적으로 생산성 향상보다는 품질 개선이라는 성과 변인에서 상호작용효과가 나타나는 경향이 있었다. 그리고 예상 가설과 달리 커뮤니케이션이 비활성화되고 낮은 경영진 신뢰의 조건에서 직무만족과 품질 개선 효과는 높은 상관 관계를 보여주었다(커뮤니케이션과 신뢰의 부적 조절 효과). 마지막으로 수평적 조직문화의 조건에서, 그리고 갈등적 노사관계의 조건에서 직무 만족과 조직 성과의 상관성이 높은 것으로 나타났다. 연구 결과의 이론적 의미와 함의에 대해 추가적인 논의를 포함하였다.

The ultimate goal of human assisted reproductive technology is to achieve a healthy pregnancy and birth, ideally from the selection and transfer of a single competent embryo. Recently, techniques for efficiently evaluating the state and quality of preimplantation embryos using time-lapse imaging systems have been applied. Artificial intelligence programs based on deep learning technology and big data analysis of time-lapse monitoring system during in vitro culture of preimplantation embryos have also been rapidly developed. In addition, several molecular markers of the secretome have been successfully analyzed in spent embryo culture media, which could easily be obtained during in vitro embryo culture. It is also possible to analyze small amounts of cell-free nucleic acids, mitochondrial nucleic acids, miRNA, and long non-coding RNA derived from embryos using real-time polymerase chain reaction (PCR) or digital PCR, as well as next-generation sequencing. Various efforts are being made to use non-invasive evaluation of embryo quality (NiEEQ) to select the embryo with the best developmental competence. However, each NiEEQ method has some limitations that should be evaluated case by case. Therefore, an integrated analysis strategy fusing several NiEEQ methods should be urgently developed and confirmed by proper clinical trials.

Purpose: Financial independence of the museum is an urgent issue in Korea. In this paper, methodology to combine arts and culture facilities with senior society is investigated based on case study of various senior programs in other countries. Methods: In this paper, case study of various senior programs from cultural and arts facilities in other countries are investigated in the aspect of public nature and independent management. Based on the analysis of the case study, optimal methodology is derived. Results: Based on case study of various senior program in other countries, it is clear that art and cultural facilities play important roles in participating elderly people to various social activities through developing programs specialized for elderly people. Conclusion: From analysis of the case study, senior program from arts and culture facilities provides more familiar contents rather than professional contents. Also, they consider more on communication and cooperation with local society to develop the senior program, which fulfill both public nature and financial independence.

Sanitary management practices from 8 packaged meals (Dosirak) manufacturing establishments were surveyd during production and distribution and their microbiological quality of dosirak items marketed in CVS were analyzed. Correlation coefficients were calculated to deternine significant relationships between sanitary management practices and microbiological quality of packaged meals. The results of self evaluation on sanitary management practices indicated 'doing practice well' in personnel and equipment sanitation management but time-temperature control management were practiced satisfactorily only about 55% as compared with the managerial standard guidelines. Significant relationships between the status of actual sanitary management practices and microbiological quality of Dosirak items were not found, but general status of microbiological quality of Dosirak items revealed positive relationship with the size of operational structure and the status of time-temperature control management practices.

Yackwa was prepared by substituting syrup with xylitol (0, 10, 20, and 30%) and the quality characteristics were evaluated. Volume and specific volume were higher in Yackwa prepared with xylitol than the control. Crude fat content of xylitol-containing Yackwa were significantly higher than that of control (p<0.05), but moisture content was not different among treatments. Incorporation of xylitol in Yackwa lowered the redness and yellowness values (p<0.05). Instrumental hardness results showed that the addition of xylitol decreased the hardness of Yackwa. Sensory evaluation revealed no significant difference in overall desirability between control-and xylitol-containing groups. Therefore, Yackwa made with up to 30% xylitol in place of syrup is as acceptable as control Yackwa without depressing sensory quality.

We conducted this study to identify the components of H&B store app service quality and their effect on customer satisfaction. The survey was conducted through an online survey for teenagers or older with experience in using H&B store app. A total of 330 copies were distributed and a total of 282 copies were used for the final analysis. The results of this study are summarized as follows: First, eight factors such as ease of use & design, fulfillment, playfulness, responsiveness, personalization, security, contextual usefulness, interactivity were derived as service quality components of H&B store app. Second, as a result of regression analysis, the six service quality components, such as 'ease of use & design', 'fulfillment', 'playfulness', 'responsiveness', 'security', and 'interactivity' were found to have a significant positive (+) effect on customer satisfaction (p<0.05) and 'playfulness (β=.372)' had the greatest effect on customer satisfaction. Based on the results of this study, we should strive to establish effective marketing strategies in the H&B industry.
