This study investigated how latent groups depend on the longitudinal trajectories observed in fathers' involvement in parenting over a five year period, and the study also determined differences in children's behavioral problems and mother's parenting stress, marital satisfaction, and depression among these groups. By utilizing 1,316 sets of data from 1st to 5th Panel Survey of PSKC beginning in 2008, we examined the patterns of the latent groups and the differences among them. The results showed that, first, a changing pattern of fathers' involvement in parenting is classified into four groups: a low-stable group, a decreasing group. a middle-high changeable group, and a highest changeable group. According to the results of the latent groups, the fathers' involvement in parenting commonly started to decrease at the children's age of 4 years old. Second, problematic behaviors of children appeared more from the fathers in the decreasing group. Third, parenting stress, marital conflict, and depression were more often found in the low-stable group that in the decreasing group. the middle-high changeable group and the highest changeable group (in that order), while marital satisfaction showed a completely opposite pattern. Based on these results, political intervention and the future direction of research for fathers' involvement in parenting are needed in order to increase better behaviors of their children as well as the psychological well-being of their mothers.

The purpose of this study is to provide diverse points of view to understand the low fertility issue of Korean society. For this phenomenological qualitative study, in-depth interviews were conducted with 14 married couples(28 persons) all raising three children. Participants were asked about overall family and work life, child care role performance, thoughts about child rearing, and their sociocultural context. Interview data were explored based on 6 analyzing steps offered by S, J, Talyor and R. Bogdan(1984). Most participants of this study were formed positive perceptions about having three children. Parents' positive perception was closely related with their attitude of not worrying too much about their children's future as well as child caring contexts around them. Parents' perception about having three children was also linked with their child care role construction process. In detail, parents with more positive perceptions tended to increase their level of child care involvement. This was particularly true for fathers. Mother and father's job situation emerged as an important factor to shape their child care involvement. In addition, child care attitude of people around them explained father's child care involvement. Applying these qualitative results, we first expect to provide detailed ideas about lives with three children in Korea. Second, based on our study findings, a more realistic and helpful policy to help the low fertility problem could be developed. Lastly, we also hope to provide helpful phenomenological qualitative research about low fertility issues of Korea.

Purpose: Individual gastric cancers demonstrate complicated genetic alterations. The PCR-based analysis of polymorphic microsatellite sequences on cancer-related chromosomes has been used to detect chromosomal loss and microsatellite instability. For the purpose of preoperative usage, we analyzed the correspondance rate of the microsatellite genotype between endoscopic biopsy and surgical specimens. Materials and Methods: Seventy-three pairs of biopsy and surgical specimens were examined for loss of heterozygosity and microsatellite instability by using 40 microsatellite markers on eight chromosomes. Microsatellite alterations in tumor DNAs were classified into a high-risk group (baselinelevel loss of heterozygosity: 1 chromosomal loss in diffuse type and high-level loss of heterozygosity: 4 or more chromosomal losses) and a low-risk group (microsatellite instability and low-level loss of heterozygosity: 2 or 3 chromosomal losses in diffuse type or $1\∼3$ chromosomal losses in intestinal type) based on the extent of chromosomal loss and microsatellite instability. Results: The chromosomal losses of the biopsy and the surgical specimens were found to be different in 21 of the 73 cases, 19 cases of which were categorized into a genotype group of similar extent. In 100 surgical specimens, the high-risk genotype group showed a high incidence of nodal involvement (19 of 23 cases: $\leq$5 cm; 23 of 24 cases: >5 cm) irrespective of tumor size while the incidence of nodal involvement for the low-risk genotype group depended on tumor size (5 of 26 cases: $\leq$5 cm; 18 of 27 cases: >5 cm). Extraserosal invasion was more frequent in large-sized tumor in both the high-risk genotype group ($\leq$5 cm: 12 of 23 cases; >5 cm: 23 of 24 cases) and the low-risk genotype group ($\leq$5 cm: 7 of 26 cases; >5 cm: 16 of 27 cases). The preoperative prediction of tumor invasion and nodal involvement based on tumor size and genotype corresponded closely to the pathologic tumor stage (ROC area >0.7). Conclusion: An endoscopic biopsy specimen of gastric cancer can be used to make a preoperative genetic diagnosis that accurately reflect the genotype of the corresponding surgical specimen.

The purpose of this study was to find out clothing evaluation criteria and purchase intention according to consumers' shopping orientation and demographic factors when they shop online. The subjects were 240 men and women living in the metropolitan area. For data analysis, factor analysis, cluster analysis, ANOVA, t-test, Duncan test and descriptive statistics were conducted. The results are as follows: 1. Important clothing evaluation criteria were considered in order of price, style, fit, size and product guarantee etc. Purchase intention was showed more highly when products are related to low involvement than high involvement. 2. Consumers with high hedonic and utilitarian shopping orientation considered clothing evaluation criteria more importantly but showed low level of purchase intention in cyber shopping. And consumers with low hedonic and utilitarian shopping orientation considered clothing evaluation criteria less importantly but showed high level of purchase intention in cyber shopping. 3. There were significant differences in evaluation criteria and purchase intention according to demographic variables. Especially women considered evaluation criteria more importantly and had higher level of purchase intention than men.

We investigate factors that influence the choice of high-share brands(HSBs) vs. low-share brands(LSBs) among various product and consumer characteristics related to brand-share perceptions. Specifically, using 8 product categories varying in terms of purchase decision involvement, we show how the influencing factors vary across the categories. At the general level that cover all the 8 categories, our hierarchical Bayesian regressions analysis shows that factors that favor high-share brands are purchase decision involvement, search goods, experience goods, price-quality relationship, positive network externalities, and price-prestige beliefs. Conversely, consumers who value variety seeking and need for uniqueness favor low-share brands. The effects of these factors, however, vary across product categories. The identification of these characteristics can help brand managers establish a more effective brand-share strategy in such areas as setting an optimal market share goal, extending a brand, and developing ad copy. Furthermore, our consumer segmentation analysis demonstrates the general market has two distinct segments - (1) a segment composed of HSB buyers(86%) and (2) a segment composed of LSB buyers(14%). The two segments are also shown to have different significant factors that explain their brand choice. Our segmentation analysis can help marketers establish a marketing strategy that targets a specific segment of interest.

The objectives of this study were to classify the contents of clothing involvement, to group elderly women into life style types. A method of this study was face to face re-search and questionnaire. Questionnaire was comprised of four sections : 18 Likert type items of clothing involvement measure ; 26 Likert type items of life style measure ; 3 items of clothing purchase measure ; and 3 demographic variables. Samples were 215 elderly women(60∼79 years of age) in Seoul, Korea. The data were analyzed using factor analy-sis, cluster analysis, one-way ANOVA, Dun-can's multiple range test,χ2 test. The results of the study were the follow-ings. 1. Four factors of clothing involvement derived by factor analysis : F.1 'clothing pleasure'; F.2 'clothing symbolism' ; F.3 'perceived risk in clothing purchase' ; F.4 'clothing interest'. 2. Four factors of life style derived by factor analysis : F.1 'active-leisure';F.2 'confidence oriented';F.3 'appearance interest';F.4 'house-work interest and community conciousness'. Three types of life style were defined by the cluster analysis of the 4 factors : T.1 'passive stag-nation'; T.3'outside activity'. 3. There were significant differences in clothing involvement factors according to life style types. Outside activity type perceived 'clothing pleasure' highest level among 3 life style types. Outside activity type and house-work and positive living type perceived 'cloth-ing symbolism' and 'clothing interest' higher level than did passive stagnation types. 4. Elderly women high in educational level were more distributed in outside activity type and the low in educational level in passive stagnation types. 5. There were significant relationships be-tween life style types and source of a clothing allowance, clothing purchase frequency, and a companion of dress store.

This study investigated the relationship of fashion brand SNS characteristics, relationship quality (satisfaction, trust, and commitment) and purchase intention. The study focused on Facebook and also examined the difference between fashion involvement groups. This study targeted consumers who have used fashion brand Facebook and are aged between 20s and 30s. Data collection was conducted through surveys, and a total 205 questionnaires were collected for the final statistical analysis. The major findings of the study were as follows. First, three characteristics of fashion brand SNS, which were entertainment, interactivity, and providing information, influenced positively on SNS users' satisfaction. Entertainment had the greatest influence on satisfaction, and providing information and interactivity followed. Second, satisfaction for fashion brand SNS influenced positively on trust and commitment. Also, trust to fashion brand SNS demonstrated a positive influence on commitment. Third, trust and commitment on fashion brand SNS both influenced positively on purchase intention. Fourth, the fashion involvement groups showed differences in fashion brand SNS characteristics, relationship quality, and purchase intention. The high involvement group showed much higher results in all aspects then did the low involvement group. Based on the above results, this study has a significant value which suggests directions for future research. Also, this paper is expected to provide managerial implications to fashion companies which need to develop SNS marketing strategies.

This study was undertaken to observe the influence of the model image and self-image congruence of consumers in Korean cosmetic advertisements on the advertising attitude and analyze the relationship between self-image congruence and advertising demand type, participation, and advertising effect, and to help develop plans to more effectively communicate advertising images. The experimental design of this study was 2 (self-image congruence: consistency vs. inconsistency) × 2 (advertising appeal: rational appeal vs. emotional appeal) × 2 (involvement: high vs. low) three-way ANOVA. The results of the study showed that the interrelationship between self-image congruence and advertising appeal type and involvement played an important role in determining the advertising attitude. More specifically, firstly, the self-image congruence of consumers in Korean cosmetic advertising affected the advertising attitude. Secondly, in the advertisements of Korean cosmetics, consumers preferred a rational advertising appeal to an emotional advertising appeal. Finally, statistical results showed significant differences in the influence of the interaction effect of the self-image congruence status of consumers and the advertising appeal on the attitude of advertising. The Korean cosmetic involvement of consumers had a significant impact on whether the Korean cosmetic advertising model image and consumer self-image were consistent with the type of advertising appeal and on the interaction effect of advertising attitude.

Objective: CT plays a central role in determining the resectability of pancreatic cancer, which directs the use of neoadjuvant therapy. This study aimed to assess the diagnostic accuracy of CT in predicting circumferential resection margin (CRM) involvement in patients with resectable or borderline resectable pancreatic head cancer. Materials and Methods: Seventy-seven patients who were scheduled for upfront surgery for resectable or borderline resectable pancreatic head cancer were prospectively enrolled, and 75 patients (38 male and 37 female; mean age ± standard deviation, 68 ± 11 years) were finally analyzed. The CRM status was evaluated separately for the superior mesenteric artery (SMA) and posterior and superior mesenteric vein/portal vein (SMV/PV) margins. Three independent radiologists reviewed the preoperative CT images and evaluated the resection margin status. The reference standard for CRM status was pathologic examination of pancreaticoduodenectomy specimens in an axial plane perpendicular to the axis of the second portion of the duodenum. The diagnostic accuracy of CT was assessed for overall CRM involvement, defined as involvement of the SMA or posterior margins (per-patient analysis), and involvement of each of the three resection margins (per-margin analysis). The data were pooled using a crossed random effects model. Results: Forty patients had pathologically confirmed overall CRM involvement in pancreatic cancer, while CRM involvement was not seen in 35 patients. For overall CRM involvement, the pooled sensitivity and specificity were 15% (95% confidence interval: 7%-49%) and 99% (96%-100%), respectively. For each of the resection margins, the pooled sensitivity and specificity were 14% (9%-54%) and 99% (38%-100%) for the SMA margin, 12% (8%-46%) and 99% (97%-100%) for the posterior margin; and 37% (29%-53%) and 96% (31%-100%) for the SMV/PV margin, respectively. Conclusion: CT showed very high specificity but low sensitivity in predicting pathological CRM involvement in pancreatic cancer.

Objectives: The purpose of this study was to investigate the relations between mother's temperament and child's and parenting attitude. Methods: One hundred twenty healthy mothers (above 20 ys) who has a child (7-11 ys) participated after informed consent. The temperament of the children was analyzed by the Junior Temperament and Character Inventory 7-11 (JTCI 7-11) by their mothers. The temperament of the mothers was analyzed by the Temperament and Character Inventory-Revised Short (TCI-RS) and the parenting attitude of the mothers was analyzed by the Parenting Attitude Test (PAT). The relations between mother and child temperament and parenting attitude were assessed using the Pearson correlation coefficient. Results: There were some significant correlations between maternal temperaments and child's temperaments and maternal parenting attitude. Maternal temperament and parenting attitude: Novelty seeking (NS) of mother had low positive correlations with punishment, high expectation and inconsistency. Harm avoidance (HA) had low positive correlations with high involvement and high expectation, and had weak negative correlations with supportive expression and rational explanation. Reward dependence (RD) had low positive correlation with rational explanation. Persistence (P) had low positive correlations with supportive expression, rational explanation and superintendence, and weak negative correlation with high expectation. Child's temperament and parenting attitude: NS of child had low positive correlations with achievement press, high involvement, punishment, high expectation and inconsistency. Low positive correlations were found in many sets such as HA and high expectation, RD and supportive expression and rational explanation, P and supportive expression and rational explanation. Conclusions: These results suggest that there are significant relations between mother and child temperament and parenting attitude the temperament of mother and child.
