The purposes of the study is to classify the psychological characteristics of gamblers using by latent profile analysis and to identify the consequences according toof the latent profiles. The subjects of the study are 473 adults gamblers who responded to a online survey about gambling patterns, basic psychological needs(BPNs), and mental health status(MHS) such as stress, depression, and anxiety. Using latent profile analysis known as the person-centered analysis, the results showed that psychological characteristics of gamblers were classified into three groups: 'Lower MHS-BPNs', 'Middle MHS-BPNs', and 'Upper MHS-BPNs'. Also, the as outcome variable, levels of problematic gambling(KCPGI) showed significant differences across the latent profiles such as Problem gambling(M=11.393) on 'Lower MHS-BPNs', Moderate-risk gambling(M=4.277) on 'Middle MHS-BPNs' and Low-risk gambling (M=1.718) on 'Upper MHS-BPNs'. Overcoming the limitations of variable-centered analysis in the existing studies, this study providesreveals new insights onin the psychological characteristics of gamblers and how different latent profiles of gamblers may be in theirdistinct levels of problematic gambling. Finally, limitations of the study and future directions for research on gambling problems are discussed.

The purpose of this study was to identify the latent styles of attachment across four major attachment figures (i.e., father, mother, best friend, and romantic partner) for Korean emerging adults. In this study, adult attachment had two dimensions (i.e., attachment anxiety and avoidance) and was measured by the Experiences in Close Relationships-Relationship Structures (ECR-RS). Data came from 317 undergraduate students in nine universities across the nation. A latent profile analysis classified the sample into four groups. (a) The "somewhat father avoidant secure" group reported the lowest levels of attachment anxiety and avoidance across close relationships but was moderately avoidant in their relationship with the father. (b) The "overall avoidant" group had the highest levels of attachment avoidance across close relationships, but along with the "father avoidant secure" group, they had the lowest levels of attachment anxiety. (c) The "romantic anxious" group was unique with the highest level of attachment anxiety toward romantic partners while reporting relatively lower levels of attachment avoidance across relationships. (d) The "overall anxious-avoidant" group was the highest in attachment anxiety and avoidance across all of their close relationships except for attachment avoidance from best friends and romantic partners, which were the highest among the "overall avoidant" group. These four groups also differed in their levels of depressive symptoms and affection for the father and the mother. This study uniquely contributes to the literature by identifying the latent attachment styles considering four attachment figures and examining the characteristics of these attachment styles.

Because existing information retrieval systems, in particular library retrieval systems, use 'exact keyword matching' with user's query, they present user with massive results including irrelevant information. So, a user spends extra effort and time to get the relevant information from the results. Thus, this paper will propose SULRM a Retrieval Model using Subject Classification Table, User profile, and LSI(Latent Semantic Indexing), to provide more relevant results. SULRM uses document filtering technique for classified data and document ranking technique for non-classified data in the results of keyword-based retrieval. Filtering technique uses Subject Classification Table, and ranking technique uses user profile and LSI. And, we have performed experiments on the performance of filtering technique, user profile updating method, and document ranking technique using the results of information retrieval system of our university' digital library system. In case that many documents are retrieved proposed techniques are able to provide user with filtered data and ranked data according to user's subject and preference.

The purpose of the study was to identify the latent classes of meta-awareness of gender discrimination among Korean young adults using Latent Profile Analysis based on 'perceived ambivalence toward men among women', 'perceived ambivalent sexism among men', 'perceived gender(reverse-) discrimination in Korea'. After identifying the latent classes, the difference between gender role conflict, sense of distance from the opposite sex, and support for gender discrimination issues were explored among the classified groups. As a result, 3 latent classes among women and 2 latent classes among men were identified. Latent classes among women were named 'women with low sensitivity of sexism', 'women with high sensitivity of sexism' and 'women against sexism' and latent classes among men were named 'men with perception of gender equality', 'men with perception of reverse discrimination'. Types with higher levels of meta-awareness of gender discrimination were related with higher gender role conflict and higher sense of distance from the opposite sex. Among women, types with higher levels of meta-awareness of gender discrimination perceived higher levels of gender discrimination and showed more support for gender discrimination issues while among men, types with higher levels of meta-perception of gender discrimination only perceived higher levels of reverse discrimination. Based on the present findings, implications about the severe gender conflict among Korean young adults are further discussed in the article.

Purpose: This study attempted to classify the potential layer for pain in the middle-aged and elderly based on the seventh Aging Research Panel Survey (2018) data and to identify the degree of depression by potential layer. Methods: This study used data from the 2018 Aging Research Panel Survey, whose participants included 6,890 middle-aged and elderly people. The data were analyzed using SPSS/WIN 22.0 and M-plus 8.0 for latent profile analysis. Results: In the study, Type 1 was a "general pain group", Type 2 was the "high back pain group", Type 3 was the "lower body pain group", Type 4 was the "shoulder pain group", and Type 5 was the "pain-free group", which included those who answered that there was no pain. Second, it was found that the variables such as gender, age, education, or not alone were statistically significant (p<.001). Third, the difference in income, subjective health conditions, depression according to the pain site type group were confirmed. Depression was significantly higher in the back pain group, lower body pain group, and shoulder pain group compared to the pain-free group. Conclusion: Developing integrative interventions is necessary to reduce depression using the pain coping skills in middle-aged and Elderly.

This study identified and compared family values within and across different generations concerning gender roles, attitudes toward diverse families, children, and parental roles. Data were obtained from the 2020 Seoul Family Report Survey. There were 1,949 study subjects, including first- and second-generation baby boomers and individuals in generations X, Y, and Z in Korea. Latent profile analyses were conducted using M-plus. Perceptions and views concerning family values were classified into different types. The main findings were as follows. Two types were identified among first baby boomers, and three were identified among second baby boomers. Most of the first and second baby boomers belonged to the "moderate" type. Two types were detected among those in Generation X. Regarding gender roles, most views of Generation X were slightly progressive, while their other family values were more moderate. Three types were identified among those in Generation Y: "progressive," "moderate," and "very liberal." Generation Z was identified as a "progressive" group. This study provides basic data to explore the direction of the coexistence of generations by identifying and comparing diverse family values within and across generations.

The purpose of this study is to analyze the types of latent profiles depending on the job satisfaction of youth entrepreneurs in South Korea and examine the influence of related variables. Latent profile analysis (LPA) was conducted using data from the 12th year of the Youth Panel Study. Results of the study revealed that there were five latent profiles based on job satisfaction among young entrepreneurs: lowest job satisfaction, mid-low job satisfaction, middle job satisfaction, mid-high job satisfaction, and highest job satisfaction. By applying multinomial logistic analysis, the influencing factors for each latent profiles have been derived. Gender, marital status, subjective health, self-esteem, entrepreneurial motivation, difficulty in start-up, person-job fit, intrinsic or extrinsic job values, business scale, income, work hour, education or training, and labor insurance were significant predictors of youth entrepreneurs' job satisfaction. Based on these results, the article discusses practical implications that can enhance the job satisfaction of young entrepreneurs.

Experiments of quenching were made with cylindrical specimens of carbon steel S45C of diameters from 12 to 30mm were performed. The specimens were heated by electric furnace and quenched by immersion method. In order to analyze the temperature profile(cooling curves) of carbon steel including the latent heat of phase transformation, nonlinear heat conduction problem was calculated by the numerical method of inverse heat conduction problem using the apparent heat capacity method. The difference between the calculated and the experimented cooling curves was caused by the latent heat of phase transformation, and the effects of the latent heat were especially manifest at the cooling curves of center of specimens. The temperature and the quantity of the latent heat of phase transformation depend on the cooling speed at A sub(1) transformation point, and the region for cooling speed to become zero was caused by the latent heat of phase transformation.

Purpose: This study analyzed the factors that increase the satisfaction of local residents' housing and residential environment, and derived implications for housing suppliers and policymakers in local areas. Research design, data and methodology: The analysis method derived latent group types through latent profile analysis, and cross-analysis and covariate variance analysis (ANCOVA) were conducted to analyze the differences between these groups. Results: The analysis results are as follows. First, there are four potential group types: good neighborhood facilities and low-level surrounding environment 1 group, low-level neighborhood facilities and good surrounding environment 2 groups, overall low-level 3 groups, and overall high-level 4 groups. Second, groups 1 and 3 tend to live in relatively old apartments. Third, as a result of distributed analysis, groups with low accessibility to neighborhood facilities but good environmental conditions and groups with high overall levels had relatively high housing satisfaction. Conclusions: As an implication, we discussed the need for development that highlights natural environment-friendly characteristics as well as access to neighborhood facilities. In addition, in order to derive more specific implications, the direction of follow-up studies considering job linkage and the effects of specific and various environmental factors was presented together.

The purpose of this study was to classify different profiles of grit (effort vs. interest) and passion mindset (fixed vs. growth) in university students and to understand whether there are differences in psychological characteristics (ie. depression, anxiety and happiness) and career adaptability between the profiles. To this end, we recruited 359 students aged 18 and 25 and applied a Latent Profile Analysis(LPA). The results revealed 4 distinct profiles : Profile1-a burgeoning type, Profile2-an ordinary type, Profile3-a fixed/limited type, Profile4-sprouting/drifting type. The profile1(LP1, 22.2%) had high levels of grit and passion growth mindset. The profile2(LP2, 63.8%) showed average levels in both grit and passion mindset. The profile3(LP3, 8.8%) had a low level of grit and a high level of passion fixed mindset. The profile4(LP4, 5.1%) showed a low level of grit and a high level of passion growth mindset. The four profiles were distinct in psychological characteristics and career adaptability. The burgeoning type(profile1) was most adaptive in comparison to the fixed/limited type(profile 3). These results suggest that grit has more powerful effects on psychological characteristics while passion growth mindset exerts stronger influencers in career adaptability. Putting the results together, our findings imply that both passion growth mindset and grit need to be considered together to enhance the individuals' comprehensive well-being and to increase the level of adaptation for career preparation.
