BACKGROUND/OBJECTIVES: The purpose of this study was to develop a dish-based semiquantitative food frequency questionnaire (FFQ) for Korean adolescents and evaluate its reproducibility and validity. SUBJECTS/METHODS: Based on 24-hour dietary recall data from the 4th Korean National Health and Nutrition Examination Survey (KNHANES), we developed a FFQ with 71 items. From a quota sample of 160 adolescents recruited using gender and age group as stratification variables, 153 participated in the complete data collection process. The FFQ was administered to each subject twice, at an interval of 3-4 weeks, to evaluate the test-retest reliability. The validity of the FFQ was assessed relative to 8-day food record data. RESULTS: The study findings demonstrated the FFQ's satisfactory reproducibility. Spearman correlation coefficients ranged from 0.64(for ${\beta}-carotene$) to 0.81(for protein). From cross-classification analyses, the proportion of subjects in the same intake quartile was highest for protein (65.4%) and lowest for vitamin A(47.1%). With regard to validity analysis, Spearman correlation coefficients ranged from 0.27(for vitamin A and fiber) to 0.90 (for energy). The proportions of subjects in the opposite categories between the first FFQ and the 8-day food record data were generally low within the range from 0.74% (for energy and carbohydrate) to 13.2% (for ${\beta}-carotene$). CONCLUSIONS: In conclusion, the dish-based semiquantitative FFQ developed in this study can be useful for grouping Korean adolescents according to major macro- and micronutrient intakes with reasonable reproducibility and validity.

Background: Breaking bad news to cancer patients is a delicate and challenging task for most doctors. Better understanding of patients' preferences in breaking bad news can guide doctors in performing this task. Objectives: This study aimed to describe the preferences of Malaysian cancer patients regarding the communication of bad news. Methodology: This was a cross-sectional study conducted in the Oncology clinic of a tertiary teaching hospital. Two hundred adult cancer patients were recruited via purposive quota sampling. They were required to complete the Malay language version of the Measure of Patients' Preferences (MPP-BM) with minimal researcher assistance. Their responses were analysed using descriptive statistics. Association between demographic characteristics and domain scores were tested using non-parametric statistical tests. Results: Nine items were rated by the patients as essential: "Doctor is honest about the severity of my condition", "Doctor describing my treatment options in detail", "Doctor telling me best treatment options", Doctor letting me know all of the different treatment options", "Doctor being up to date on research on my type of cancer", "Doctor telling me news directly", "Being given detailed info about results of medical tests", "Being told in person", and "Having doctor offer hope about my condition". All these items had median scores of 5/5 (IQR:4-5). The median scores for the three domains were: "Content and Facilitation" 74/85, "Emotional Support" 23/30 and "Structural and Informational Support" 31/40. Ethnicity was found to be significantly associated with scores for "Content and Facilitation" and "Emotional Support". Educational status was significantly associated with scores for "Structural and Informational Support". Conclusion: Malaysian cancer patients appreciate the ability of the doctor to provide adequate information using good communication skills during the process of breaking bad news. Provision of emotional support, structural support and informational support were also highly appreciated.

Following the global trend of the delayed transition to adulthood, the number of unmarried middle aged adult children living with, or economically dependent on their parents has increased in Korea. Middle aged adult children in Korea are traditionally expected to satisfy their duty to support their elderly parents both in economic and emotional needs. This study aims to explore group differences in unmarried adult children in their mid 30s or older and in parents having unmarried middle aged child(ren) depending on co-residency and the children's eonomic dependency in Korea. Using quota sampling in terms of living arrangements (living together vs. living apart), 500 unmarried adult children 35 years of age or older and 500 elderly parents, having at least one unmarried child in the mid of 30s or over, were selected in Seoul, Korea in June 2016. First, the findings show that unmarried adult children living together with their parents and depending on their parents economically were in the lowest level of educational achievement and the lowest level of monthly average income among the respondents. Second, both unmarried adult children and parents from the group of co-residency and economically dependent showed the lowest level of psychological well-being. Third, parents from the group of co-residency and economically independent had mostly positive relationships with children, whereas, parents from the group of living apart and economically dependent reported the most negative relationships. Finally, respondents included in the group of co-residency had positive attitudes toward marriage and the support for their elderly parents regardless of the child's economic dependency. This study has implications for the increasing number of unmarried middle aged adult children and their elderly parents.

The purpose of this study was to clarify that the effect of consumer's perception of nail store attributes has on intent to revisit (focus on independent stores) by performing quantitative research. The importance of nail stores is increasing with sales amounts and the number of workers, however, previous research in this area is not complete. The reason that this qualitative research should be done before the quantitative research is due to the scant theoretical background in this matter. As the nail market is steadily increasing, determining the factors to make a successful and influential store leading to revisits is very meaningful both academically and in business. For the quantitative study, consumers from 20 years old to less 60 years old who had purchased nail service at independent nail stores were included in the survey. Quota sampling was adopted in the areas where the independent nail stores were located from May 10th to May 30th, 2019, and 262 questionnaires were collected, and those containing insincere respondences were excluded. The most important nail store attribute was reliability (store name value, relationship with workers and A/S) and then the physical environment, economics, product, and promptness. The result depended on demographic factors- younger and lower-income respondents put a premium on the physical environment, promptness, and economics, on the other hand, older and higher-income respondents placed a priority on reliability. The correlation analysis result is that all store attributes (reliability, physical environment, economics, promptness, product) show a statistical significance. A multiple regression analysis was conducted to determine the effects of nail store attribute importance on revisit intention. Promptness, economics, and the physical environment have a statistically significant effect on the consumer's revisit intention.

우리나라에서 수행되는 사회조사들은 대부분 지역, 성과 나이대를 고려한 할당추출법(quota sampling)을 사용하며 전화번호부를 표집틀로 한 전화조사가 주류를 이룬다. 이러한 표본들이 지역, 성, 나이대 외의 인구사회적 속성 측면에서 모집단을 잘 대표하는지, 아니면 일정 방향으로 기울어져 있는지를 검토할 필요가 있다. 또한 표본 편향을 줄이기 위하여 가중법을 적용하는 경우 조사 결과에 어떤 영향을 주는가를 살펴볼 필요가 있다. 이 연구는 2000년부터 2003년 사이에 전화조사로 수행된 18례의 사회조사에서 표본의 모집단 대표성을 지역, 성. 나이대, 학력과 직업 측면에서 살펴본 것이다. 사례들을 종합한 결과, 지역, 성과 나이대를 보정한다고 하더라도 표본들에서 고학력자와 가정주부가 과다하고 반면 저학력자와 자영업/블루칼러, 화이트칼러가 과소한 것으로 나타났다. 학력과 직업에서의 왜곡은 많은 사회조사에서 본조사 항목의 편향을 초래할 가능성이 있다. 반복비례가중법으로 이러한 표본왜곡을 시정하여 보았더니 본조사 항목에서 원조사 결과와 상당한 차이가 나타났다. 가중치 보정을 하면 유효표본크기가 감소하는 결과가 초래되는데, 각 조사가 명목적으로 제시하는 일정 수준의 오차한계를 지키기 위해서는 현재보다 20~4-% 정도 표본을 크게 해야 한다는 결론을 얻었다.

Korea-Us FTA negotiation started in February 2006 with a view to overcoming those uncertainties in the global market and was finally concluded in April, 2007. The Agreement was officially signed between ministers two month later and it is expected to be ratified this year even though the process is most likely to be painful in both countries by the political resistances. For the new President of the United States, effective leadership will depends largely on how to encourage domestic industries such as Automobile industry and Iron and Steel industry from the financial crisis. Many trading partners of US worry about US foreign trade policy changes to protectionism that might be unequal to bear. Korea textile industry is one of the major industry in Korea as it occupies 15% of total number of manufacturers, 11% of total employment and 5% of national GDP. Korea-US FTA will provide a breakthrough for bouncing back by exploring new market. US agreed to remove all tariff and non-tariff barriers to 87% of textile items under trading. This study shows that Korean textile industry has been losing it's competitiveness as textile quota system abolished in the year 2005 and has been traced by pursuers such as China, India and Vietnam. In case of woven fabric which was a representing export item of Korea lost price competitiveness against China after 2005. This study seeks the strategy of Korea textile industry in the US market by utilizing the capacity of KOTRA offices in US. All possible statistical data obtained in the US were used for analysing the competitiveness. Fabrics and Garments are analysed independently with a view to finding out real trends of textile market in US. This study also suggest Korea's textile industry strategic ideas obtained from the potential buyers to show the way to penetrate into US market.
