The main purpose of this study is to analyze job sequences according to poverty profiles that the working poor have had. For the stated purpose, this study examines characteristics and patterns of job sequences by diving the subgroups, using the 10 year data of KLIPS and the sequence analysis. Major findings are as follows. The working-transient poor have different characteristics, such as longer working term, less job change, less number of gap and length, and relatively higher monthly income, from the working-recurrent poor and the working-persistent poor. However, there are no different characteristics between the working-recurrent poor and working-persistent poor, except for monthly income. Job sequences are divided into 5 clusters and job sequences types according to the working poor subgroups are quite different. Such analysis results would contribute to planning poverty policies based on job sequences differently seen in subgroups and finding specific policy alternatives to relieve the working poor.

It is worthwhile to compare the major social indicators between Korea the and Taiwan particularly focusing on population because two countries share close similarities in many aspects and gave access to the advanced level among the developing countries in recent years. Similarities or dissimilarities presented in this paper will be helpful to the researchers and the policy makers of the two countries by giving them insight on the situation. The similarities and dissimilarities between the two countries in the field of demography and social indicators are summarized as follows : 1. Similarity indicators can be found in fertility. One of them is Net Reproduction Rate and it was less than one in both countries in 1985. The past trend of fertility, in fact level and pattern of it, of the two countries from 1960 to 1985 has been very similar. 2. Level and pattern of mortality is quite different between two countries. Mortality level of Taiwan is lower than that of Korea. 3. The close similarity between two countries was shown in population structure and aging index. 4. On future population projection, the population structure and the level and pattern of fertility of the two countries are very similar. During fourty years, the period from the current population growth rate which is a little more than 1% to the zero growth rate, the annual population growth rate of the two countries is approximately 0.6% and that is similar to those of the current industrialized countries. According to the medium variant of the projection, Korean population will reach Zero Growth Rate between 2020 and 2025 whereas Taiwan between 2025 and 2020 5. Current level of contraceptive prevalence of both countries is very similar showing above 70% of the eligible women in 1985 and one of the valuable factors of achieving this high rate within short period must be the national program of the family planning. A close cooperation in the field of population policy formulation and its implementation is indispensable because Korea and Taiwan have similarity in many population indicators.

Objective: To investigate differences in the heritability of skeletodental characteristics between twin pairs with skeletal Class I and Class II malocclusions. Methods: Forty Korean adult twin pairs were divided into Class I (C-I) group (0° ≤ angle between point A, nasion, and point B [ANB]) ≤ 4°; mean age, 40.7 years) and Class II (C-II) group (ANB > 4°; mean age, 43.0 years). Each group comprised 14 monozygotic and 6 dizygotic twin pairs. Thirty-three cephalometric variables were measured using lateral cephalograms and were categorized as the anteroposterior, vertical, dental, mandible, and cranial base characteristics. The ACE model was used to calculate heritability (A > 0.7, high heritability). Thereafter, principal component analysis (PCA) was performed. Results: Twin pairs in C-I group exhibited high heritability values in the facial anteroposterior characteristics, inclination of the maxillary and mandibular incisors, mandibular body length, and cranial base angles. Twin pairs in C-II group showed high heritability values in vertical facial height, ramus height, effective mandibular length, and cranial base length. PCA extracted eight components with 88.3% in the C-I group and seven components with 91.0% cumulative explanation in the C-II group. Conclusions: Differences in the heritability of skeletodental characteristics between twin pairs with skeletal Class I and II malocclusions might provide valuable information for growth prediction and treatment planning.

There is a growing demand for public rental housing since housing price increased rapidly and socially vulnerable people need more stable housing. The purpose of this study is to investigate housing evaluation (satisfaction), moving plan, and residential service according to the type of the public rental housing and the characteristics of the resident, and to suggest the development direction for comprehensive housing services including the community level. Data used for analysis in this study are from 2016 Seoul panel survey of public rental housing residents. A total of 3009 questionnaire from public rental households were collected in 2016 Seoul panel survey. In order to investigate housing requirements, we analyzed household characteristics, housing satisfaction, moving plans, welfare services, residential activities and community facilities, social environment. In this study, the difference of residential satisfaction, moving plan, and residential service according to the type of the public rental housing and the characteristics of the resident is analyzed to identify their housing demands. As a result, there were differences in residential satisfaction, moving plan, and residential service depending on type of public rental housing and characteristics of residents. Residents in public rental housing modified from the multi-family housing after purchase showed lower residential satisfaction, and higher intention for moving plan compared to residents living in other type of public rental housing. In the residential service, residents in permanent lease type have higher experience of housing service as well as demand on housing service. Especially single household, elderly household, female household, or household with handicapped person indicated higher demand for housing services.

The purpose of this study is to analyze the distribution characteristics of the agency-managed shared housings in Seoul and draw the possible implications from it. The needed data for the study was obtained from an on-line shared housing portal service which provides housing information from various shared housing management agencies. By mapping out the locations and other related data into a GIS(Geographic Information System) program, this study shows that shared housings in Seoul can be sorted into four large clusters. Each cluster has a different ratio of housing types and room capacities reflecting each regional circumstance and common causes. Women-only shared housing takes up 79% of the overall shared housing ratio and, while multi-family housing type has the most count, the apartment type has a noticeably high ratio in women-only housing compared to the apartment type ratio among the other gender-specific housings. Given the high crime rate against the single-person household of young adult women, the reason for the popularity of shared-apartment housing among young women can be deduced. However, the potential tenants' practical choices and their concern for safety are not the only causes that drive the current shared housing market. The young adults in their 20's and 30's choose to live in popular places where they can engage social activities. A new tier of shared housing market has also appeared in places where young adults could not have afforded if they lived alone. Choosing where we live is no longer about just meeting the requirements for a house based on what she/he needs but also about satisfying the preferences for a living based on what she/he desires. This paper indicates that although there is an undeniable premise that 'sharing a house' revolves around the realm of housing welfare and is not a typical topic for the upper-income households, the way we live and how we choose our place to live is shifting.

The purpose of this study is to propose a modeling methodology through the exchange of coordinate data of a three-dimensional custom curtain wall panel between Rhino and Revit, and to examine the validity of the model implemented in the drawing. Although the modeling means and method are different, a fundamental principle is that all three-dimensional modeling begins by defining the position of the points, the most primitive element of geometry, in the XYZ coordinate space. For the BIM modeling methodology proposal based on this geometry basic concept, the functions and characteristics associated with the points of Rhino and Revit programs are identified, and then BIM implementation process model is organized and systemized through the setting of the interoperability process algorithm. The BIM implementation process model proposed in this study is (1) Modeling and panelizing surface into individual panels using Rhino and Grasshopper; (2) Extraction of vertex coordinate data from individual panels and create CSV file; (3) Curtain wall modeling through Adaptive Component Family in Revit and (4) Automatic creation of Revit curtain wall panels through API. The proposed process model is expected to help reduce design errors and improve component and construction quality by automatically converting general elements into architectural meaningful information, automating a set of processes that build them into BIM data, and enabling consistent and integrated design management.

This study examines the perception and its meaning of child education and mother]s role for children of Korean mothers for their children to study abroad in Malaysia. For this purpose, data was collected through in-depth interviews with seven mothers and one grandmother. All participants were lived in Malaysia for at least 6 months above. As a result, the most of recommenders of studying in Malaysia were fathers. And the purposes of studying in Malaysia were the improvement of their children's English learning skills and abilities, and not-good academic achievement in Korea. They made a decision for their children to study in Malaysia in that it was good to study in Malaysia for early 'spec' management for their children. But in the case of Korean mothers, they had a diverse desires internally. For example, they had a desire to escape from the relationships with mother-in law or complicated social relations of their family, kin, and neighbors in Korea. In Malaysia, Koran mothers carried out their roles of children's time management, information network management and 'distinction' strategies to their friends and neighbors for their children to study well and up their achievements' levels. Lately, they had planning to develop for their children's long term life design and their choices of universities in Korea, with special reference to the various connections of school-ties and religion-ties in Malaysia.

The aim of this study was to evaluate the genetic parameters of growth traits for improvement breeding in olive flounder Paralichthys olivaceus at the 8^th generation of selective breeding in April 2021. Growth traits such as total length, body weight and condition factor at 11 months of age were measured for 7,508 individuals with confirmed paternity. Data were analyzed using the restricted maximum likelihood method applied to a multiple traits animal model. The effects of sex and family were significantly different across traits (P<0.05). The heritability values of total length, body weight and condition factor were estimated to be high as 0.479, 0.457, and 0.466, respectively. Correlation analysis between phenotypic and breeding values, indicated that the selection accuracy was 75.9-85.2% for all traits. To increase the selection accuracy for parent fish selection, the sex and pedigree characteristics that affect each trait should be considered. Moreover, further improvement of multiple traits can be achieved if the correlation between each trait is appropriately considered.

The supply of housing can be understood through a close relationship with the urbanization phenomenon. Through industrialization and urbanization, many cities have implemented systems and policies for housing supply due to population concentration in cities, poor housing quality, and lack of housing. In the case of the Netherlands, the Housing Act was enacted in 1901 to improve the residential environment during the period when the population was concentrated in the city, and various efforts were made to expand the housing supply. Through this process, we understand the background of collective housing types in the Netherlands and analyze the application stages of contemporary residential housing planning in Rotterdam and Amsterdam. On the other hand, through the experience of Western society, we examine how to view the problem of multi-family housing types in our society, where the proportion of apartments is continuously increasing.
