As polarization and class reproduction between generations are considered to be serious problems in Korean society, increasing number of assortative mating, which means marrying between homogeneous family background, income class, and educational background, is on the spotlight socially. Some worry that the increase of assortative mating can reinforce closure of social mobility so it deepens inequality and limits class mobility between generations. This research analyzes the effects of accomplishment characteristics of husbands and wives and ascriptive characteristics of parents which consist the concept of assortative mating, on income, consumption, and assets those represent economic status of a family. The purpose of this research is to suggest empirical understanding on the role of assortative mating that affect on inequality within generations and income mobility between generations in Korean society. In the result of multiple regression analysis on the effect of assortative mating on income, consumption, and assets, high educational background was the factor that increase income and consumption level as accomplishment characteristics of assortative mating. As ascriptive characteristics of assortative mating, educational homogeneous of fathers was the factor that increased asset level. While accomplishment characteristics affect income and consumption, ascriptive characteristics of homogeneous had significant effect on assets. Thus, it was found that transfer between generations had effects around asset rather than income. In particular, ascriptive characteristics in young husbands and wives aged 20s or 30s had significant effect only on the assets.

The 'Joongsancheung(JSC)', a unique term for the middle class in Korea, is defined as a stratum sharing common lifestyles and a certain level of life chances. It involves non-economic factors such as life chance, educational attainment, occupational groups as well as economic factor. Such objective measures as the occupational status of the main breadwinner, family income, and the educational level of respondent, and subjective measures of class identification are used for the operational definition of the JSC. Data from a national survey of 1,515 respondents is analyzed to investigate the change of the JSC in size and the major determinants of class identification. The results show that while there is no strong evidence of any significant change of the JSC by the objective measures during the recent decade, there seems to be a slight decrease in the subjective class identification. In addition, binary logistical regression analysis reveals that self-identification of JSC is heavily influenced by house ownership, along with subjective evaluation of one's own income and property ownership. This study demonstrates that the apparent class polarization in Korean society reflects not so much objective conditions but subjective perception of respondent of his or her circumstance. It is suggested that problems of housing and relative derivation people have as regards income and property should be resolved to alleviate such class polarization in Korean society.

This study focuses on evaluating that South Korea has the territorial right of Manzhouguo with disconfirming that China had the territorial right of Manzhouguo after the Second World War. This study also suggests the necessity of territorial cultures with establishing the theory of cultural territories and territorial cultures. The four main territorial cultures of Manzhouguo that are the burial culture, the place name cultural, the cadastral, and the folk culture were analyzed with Classifying territorial cultures. The results shows that territorial cultures of Manzhouguo is the same with territorial cultures of South Korea. Thus, This study suggests that territorial cultures of Manzhouguo should be vest to South Korea and not to China, because of the theory of cultural territories, which is that territorials can be defined with cultures and territorial cultures, which cultures can be defined with territorials.

Recently, one of the issues to be discussed from the viewpoint of product management in National R&D Programs is about the management of intellectual property produced by joint research and development. According to existing legislative system, the main R&D institute and collaborative enterprise own the patent produced by joint R&D activities together at the rate of investment. But, there are many discussions if that is right in legal principles and in substance. Patents by Cooperative National R&D Programs are very different from common patents because of its characteristics and have scheme controlled complexly by related laws and ordinances. This paper aims to review the legal theory on the possession and utilization of patents produced by Cooperative National R&D Programs, and to try to find out the improvement of existing legislative system. For this purpose, after looking into the meaning and the legal system of Cooperative National R&D Programs, and examining the ruling theory on the possession and utilization of co-invented patent, finally research the problems and improvement of existing related legislative system.

소프트웨어 품질을 정의하기 위한 여러 가지 소프트웨어 품질 모형(SQM : Software Quality Model)이 개발되어 왔다. 이 모형들은 두 가지 목적을 가진다. 한 가지는 소프트웨어 품질 측정이고, 또 다른 목적은 개발 프로세스에서의 소프트웨어 품질 제어이다. 국제 표준인 ISO/IEC 9126은 소프트웨어 측정을 위한 소프트웨어 품질 모형을 제시하였다. ISO/IEC 9126의 품질 모형은 사용 관점에서 소프트웨어 품질을 정의한 모형이다. 이 모형은 개발 프로세스에서의 품질 제어를 하는 측면에서는 불완전한 모형이다. 소프트웨어의 품질이 프로세스 내에서 어떻게 만들어지는지 볼 수 없는 모형이기 때문이다. 따라서, 개발 관점에서의 소프트웨어 품질 모형이 필요하다.본 논문에서는 사용 관점인 ISO/IEC 9126 품질 모형을 기반으로 하여 개발 관점에서의 소프트웨어 품질 모형을 제안한다. 이 모형은 ISO/IEC 9126과 같이 하위 품질 요소가 중복되지 않는 계층적 품질 모형이면서, 개발 프로세스 내에서 제어 가능한 제품 특성에 기반을 둔 개발 관점의 소프트웨어 품질 모형이다. 본 논문에서는 소프트웨어 품질 모형 구축 시, 품질 속성간의 선후조건관계를 설정하여 품질 속성간 중복되었던 제품 특성을 한 품질 속성 내 귀속시킨다. 품질 속성 별 제품 특성을 기반으로, 프로세스 내에서 제품 특성을 측정하는 메트릭스를 제안한다. 본 논문에서 제안한 품질 모형과 ISO/IEC 9126을 비롯한 기존 품질 모형과 비교 분석한다.Abstract Several SQMs(Software Quality Models) have been developed to define a software quality. These models have two goals. One is to measure a software quality, the other is to control a software quality. The SQM of ISO/IEC 9126 is defined from the user's viewpoint. This model is an incomplete model in controlling a software quality in the development process. Since this model cannot show how to build a high quality software, the SQM of the developer's view is needed.We suggest the SQM of the developer's view. This model is a completely hierarchical model and is based on product properties. For this model, we define implicative relations among quality attributes for 1:m relations of quality attributes and product properties. So, we solve the problem of a quality attribute overlapping with other quality attributes. We suggest metrics based on our SQMs. Further, we evaluate our SQM by comparing our SQM with other SQMs.

This paper investigates the possibilities of protecting game developers under the work-for-hire provision of copyright law. Fundamentally, the work-for-hire clause provides the authorship status to companies, not to game developers. Some argue that the clause is especially appropriate in software industries including game industries because they are new and different from typical types of copyright industries. However, game industries are different from software industries as well as typical types of copyright industries in that they have both cultural (artistic) as well as industrial characteristics. Game developers not being provided with the authorship status may be one of the reasons for the disputes related to turnover and knowledge leakage. This paper mainly suggests three kinds of solutions: first, protecting the moral right even in the work-for-hire provision; second, protecting game developers as coauthorship; and third, providing monetary compensation as it is in employee invention.

This study aimed to investigate the effect of Chinese on the production of Korean rhythm. Korean and Chinese are typologically classified into different rhythmic categories; because of this, the phonological properties of Korean and Chinese are similar and different at the same time. As a result, Chinese can exert both positive and negative influences on the realization of Korean rhythm. To investigate the influence of the rhythm of the native language of L2 learners on their target language, we conducted an acoustic analysis using acoustic metrics like of the speech of 5 Korean native speakers and 10 advanced Chinese Korean learners. The analyzed material is a short paragraph of five sentences containing a variety of syllable structures. The results showed that KS and CS rhythms are similar in %V, VarcoV, and nPVI_S. However, CS, unlike KS, showed characteristics closer to those of a stress-timed language in the values of %V and VarcoV. There was also a significant difference in nPVI_V values. These results demonstrate a negative influence of the native language in the realization of Korean rhythm. This can be attributed to the fact that all vowels in Chinese sentence are not pronounced with the same emphasis due to neutral tone. In this sense, this study allowed us to observe influences of L1 on L2 production of rhythm.
