  • 국내산 콩과 수입콩의 판별에 NIRS를 도입함으로써 보다 빠르고 정확한 식별분석을 하고자 실험을 수행하였다. NIRS를 사용하여 400~2,500 nm 범위에서 콩 분말의 파장을 측정하였으며, 측정된 spectrum은 WINISI II program 을 이용하여 수처리와 회귀분석을 하였다. 검량식 작성을 위한 수처리는 spectrum을 1차미분 및 4 nm gap으로 조정한 것이 가장 적합하였으며, 회귀식은 변형부분최소자승회귀법(Modified partial least squares regression)이 우수하였다. MPLS 회귀분석시 원산지 판별을 위해 loading value를 국내산 콩은 '100', 수입콩은 '1'로 처리하여 검량식을 작성하고 그 적합성을 검증한 결과 factor가 10일 때 도출된 calibration equation의 상관값이 0.98, 교차검증의 상관값이 0.94를 나타내어 상관도가 높음을 알 수 있었다. 따라서 NIRS를 이용한 국내산 콩과 수입콩의 판별분석이 가능할 것으로 판단되었다.

  • The purpose of this study was to examine the effect of stress types and coping styles on the relationship quality with mothers-in-law perceived by sons-in-law. The data was collected from 300 sons-in-law aged 20~49 by using a survey questionnaire. The main results of this study were as follows: first, factor analysis yielded 4 types of coping(cognitive understanding coping, avoidant coping, direct behavior coping, and indirect behavior coping) and 7 types of stress(despising poor ability and condition, interference in daily life, son-in-law discrimination, wife discrimination, uncomfortable interaction, differences in lifestyle, and excessive demand). Second, the total stress perceived by sons-in-law in the relationship with their mothers-in-law was affected by avoidant coping and cognitive understanding coping. Finally, the relationship quality between mothers-in-law and sons-in-law was influenced by avoidant coping, uncomfortable interaction stress, direct behavior coping, differences in lifestyle stress, son-in-law discrimination stress, interference in daily life stress, frequency of meeting, cognitive understanding coping, indirect behavior coping, and age. Consequently, it was confirmed that sons-in-law's coping styles with stress from their mothers-in-law was more influential than the amount of stress perceived by sons-in-law on the relationship quality with their mothers-in-law. Especially, 'avoidant coping' among 4 styles of coping and 'uncomfortable interaction stress' among 7 types of stress influenced the relationship quality between mothers-in-law and sons-in-law the most.

  • A large number of branded chicken products exist in Japan, and in some cases, the breed of chicken is an important factor used to attract consumer interest in the retail product. In order to establish a simple method for verifying such breed claims we applied the amplified fragment length polymorphism (AFLP) technique to nine chicken breeds (White Cornish, Red Cornish, White Plymouth Rock, New Hampshire, Rhode Island Red, Barred Plymouth Rock, Hinaidori, Tosajidori, Tsushimajidori) to search for molecular markers able to discriminate chicken breeds. Three breed-specific single nucleotide polymorphisms (SNP) were identified, one for each of Hinaidori, Tosajidori, or New Hampshire. A total of 219 individuals from the nine breeds were analyzed using a specific PCR test for each of these SNP. The PCR tests made it possible to discriminate between the breeds of chickens to identify products from these three breeds. This PCR method provides an efficient method for the routine analysis and verification of certified chicken products.

  • Somatotypes in the lower torso and legs of adult females were classified and discriminated. Then their distribution according to the age groups was studied. The subjects were 343 females of 18 to 49 year-old. 36 anthropometric and 21 photographic measurements were taken to each subject. The results were as follows: 1. The somatotypes in the lower torso and legs were classified into 4 types and their differences were shown by analysing factor scores and anthropometric values according to each somatotype. 2. The shape characteristic of tile classified somatotypes was represented by the rating scale of Heath-Carter. 3. The lateral silhouettes of 4 types were compared with balanced type which is type 3 in this study. 4. Individual somatotype in the lower torso and legs could be discriminated from the measured anthropometric data without modifying the data. Anthropometric data, which are needed for discriminating individual somatotype, are waist circumference, posterior waist height, and hip circumference. 5. The distribution of the somatotypes in each age group showed that the dominant somatotype of each age group was different and any somatotype was shown in a specified age group but rarely in other age group.

  • This study was conducted in order to develop a Children's Playfulness Rating Scale(CPRS) and to analyze it in terms of item discrimination, validity, and reliability. The participants in this study consisted of 861 parents whose children were aged from three to six years old. The item discrimination, determined by comparing the highest and lowest group using ${\chi}^2$, Cramer's V, was found to be satisfactory. The reliability of factors, as measured by Cronbach's ${\alpha}$, ranged from .85 to .95. The results of factor analysis identified 4 factors and 35 items were then selected from the 45 items in the original scale. The four factors identified were as follows; (1) leading participation (2) cognitive flexibility (3) expression of joy (4) voluntary full immersion. Concurrent validity was also established by using correlations between the CPRS and CPS(Children's Playfulness Scale). In conclusion, these results demonstrated that the Children's Playfulness Rating Scale is both reliable and valid.

  • The purpose of this study was to develop a family functioning scale that is suitable for Korean families. The data for this study were obtained from a survey on a sample of 350 mothers of school-age children, who were living in Seoul, Kyunggi-do, and other cities of Korea. The major findings ate as follows; 1) Through the item discrimination test, 63 of the 77 items were found to be significant, thus deemed acceptable. The level of discrimination indices of the 63 items ranged from .38 to .84. 2) A factor analysis was conducted on the 63 items. Six different factors (Emotional Support, Family Intimacy, Respect for Autonomy, Communication, Family Rules, Time Spent Together) emerged for 37 items. The six factors accounted for 56.51% of total variance. 3) A multiple regression analysis was conducted to reduce the number of items, and the final 36 items were selected for the Family Functioning Scale. 4) The reliability measured by the internal consistency of the 36 items was high (Cronbach's a =.93). 5) The Family Functioning Scale was found to have a significant correlation with FACESIII(r=.80) as well as with FAD(r=.78).

  • The purpose of this study was to examine Korean-Chinese parent-child relationship values through Korean proverbs on parent-child relationships. A total of 233 Korean-Chinese who reside in Yungil, China participated in this study. The participants were recruited through Korean-Chinese preschools and elementary schools. They completed a questionnaire which asked to what extent they agreed or disagreed with Korean proverbs. The items were classified into four categories: filial piety (duty), child-care and education, childrearing practices, and traditional son preference (and daughter discrimination). The results showed that, although the participants highly agreed to the meaning of the proverbs, they seldom used Korean proverbs in their daily lives. The findings concluded that the participants generally manifested a traditional value of filial piety or duty. Also, the findings showed that more fathers acclaimed the value of traditional son preference (and daughter discrimination) than mothers. Finally, the degree of familiarity with Korean culture was found to be a major factor in explaining differences in levels of agreement or disagreement to the proverbs. Since Korean-Chinese ethnic minority groups in China tend to adhere to traditional Korean values, they might encounter more challenges assimilating into the mainstream Chinese culture.

  • The purpose of this study is to develop a scale for evaluation of Parent's Literacy Interaction Rating Scale (PLIRS) for preschool children and to examine its validity and reliability. The participants of this study were 342 Korean mothers with children of 3 to 5 year olds. The methods for data analysis included item analysis, factor analysis for construct validity, Pearson correlations between PLIRS and two sub tests of EC-HOME for concurrent validity, and Cronbach's ${\alpha}$ for reliability. The item discrimination was determined by comparing the highest and lowest groups using Chi-square (${\chi}^2$), and Cramer's V. The 25 items of the scale were found to be satisfactory in item discrimination. The concurrent validity was also identified by correlation between PLIRS and two sub tests of EC-HOME. Factor analysis revealed that the structure of the PLIRS consisted of three factors: 'open interaction', 'directive interaction', and 'picture-book reading interaction'. 'Open interaction' is based on 'Whole Language Approach', such as 'I have my child write as he/she likes even if they spell wrongly.' 'Directive interaction' is based on 'Code Emphasis Approach', such as 'I have my child take dictation.' 'Picture-book reading interaction' is how parents read picture-book with her/his children, such as 'When I read a picture book to my child, I ask various questions about a book story.' The Cronbach's ${\alpha}$ for internal consistency reliability range was .78 to .87 for three subscales. It was concluded that PLIRS was valid and reliable to examine the literacy interaction between parents and children in home.
