The purpose of the study was to investigate the effects of money transfer between generations on preparation behaviors for retirement, separated into assets and saving for retirement. The survey was conducted by targeting 422 married people across the nation. The factor of money transfer between generations was defined as the inheritance and gift variable. The data were analyzed using SPSS 20. Correlation, analysis of variance (ANOVA), and multiple regressions were utilized. The results indicated that preparation behaviors for retirement are affected by the economic independence of parents, inheritance, expenses for children's education, and marriage. Retirement assets were significantly affected by inheritance, the economic independence of parents, educational expenses for children, financial assets, and amount of debt, while the significant factors related to retirement savings were interests on retirement, income, wedding expenses for children, economic independence of parents, and educational expenses for children. It was concluded that the financial preparation for retirement ought to be expanded from one household's finances to finances between generations.

Object-oriented databases (OODBs) canbe used for many non-traditional database application areas such as computer-aided design, etc. Usually those application areas require advanced modeling power for expressing complicated relationships among data sets. OODBs have more distinguished features than the traditional relational database systems. One of the distinguished characteristics of OODBs is class hierarchy (also called inheritance hierarchy). A class hierarchy in an OODB means that a class can hand down the definitions of the class to the subclass of the class. In other words, a class is allowed to inherit the definitions of the class from the superclass. In this paper, we present performance evaluation metrics for class hierarchy in OODBs from a concurrency control perspective. The proposed performance metrics are developed to determine which concurrency control scheme in OODBs can be used for a given class hierarchy. In this study, in order to develop performance metrics, we use class hierarchy structure (both of single inheritance and multiple inheritance), and data access frequency for each class. The proposed performance metrics will be also used to compare performance evaluation for various concurrency control techniques.

This study was undertaken to investigate the inheritance in craniofacial complex among Korean familial members. The subjects were 160 lateral cephalometric radiographs from 45 families. Standard product-moment correlation coefficients(r) were calculated for the measurements between the familial pairings. Further, coefficients of $determination(r^2)$ were calculated and multiple regression analyses were performed to assess the use of parents' record for predicting an offspring's craniofacial features. The following results were obtained. 1. First-degree relatives had a high level of significant correlations which were compatible with a polygenic theory of inheritance than those of non-relatives. 2. Mother-daughter pair had the highest significant correlations, then mother-son and father-son pairs, and, finally, father-daughter pair had the lowest significant correlations. 3. The genetic influence was higher in anterior cranial base length and genial angle. In contrast, the environmental influence was higher in posterior border of ramus, maxillary ant. teeth, maxillary & mandibular apical bases and Gla-P. occ. 4. The predictability of offspring's cranio-facial growth could be improved by using multiple measurements from both parents than those from father or mother only.

In this study, I grasped the actual conditions of folk exhibition hall in Chungbuk area. From this data I researched basically as the fundamental role of regional museum, eco-museum core center facilities, the connection with islanded and various inheritances, and central facilities whole area to the museum. And I could get following conclusion. First, on the studied result of folk exhibition hall in chungbuk area, it is not enough the activity of unearthing, collection, study etc. that is basic activity of the museum because the museum just permanently displayed historical contents of the area and simple life folk data. Second, add to existent museum concept and have to widen viewpoint to the museum which whole area is no roof, and utilize folk exhibition hall as the central facilities. Specially, there are a lot of difficulties to communicate information to visitors because of the absence of cultural heritance exponent. So a plan that local resident participate actively in museum activity may have to be considered. Third, the concept of inheritance limited in historical culture of area has to be widening by nature and industry etc. And we should keep up study that is the linked plan to scattered conservation remains, inheritance and tourist place in area.

The fragment in intron I of FSH-${\beta}$ gene was amplified by PCR. According to the polymorphism, we analyzed the distribution of FSH-${\beta}$ retroposon in different pig breeds; its inheritance pattern in Large White${\times}$Meishan reference family; and the association of FSH-${\beta}$ retroposon with litter size, female reproductive organs measurement, ultrasonic backfat and other traits. The results showed that almost each Chinese indigenous pig had the retroposon, while foreign pig breeds rarely had; the frequencies of porcine FSH-${\beta}$ retroposon were strongly associated with breeds (p<0.01); the pattern of inheritance was consistent with Mendelian fashion; total number born (TNB) and number born alive (NBA) were increased per FSH-${\beta}$ retroposon (p<0.01) with additive effects of 1.2-1.8 and 1.4-1.8 pigs/litter, respectively; between the FSH-${\beta}$ retroposon carriers and non-carriers, there was an insignificant difference in the measurement of female reproductive organs, body weight at birth, backfat thickness, loin meat height, lean meat percentage, teat number, days to 100 kg, and average daily gain.

Worldwide, cyst nematode(Heterodera glycines Ichinohe) is the most destructive pathogen of cultivated soybean. In the USA, current annual yield losses are estimated to be nearly a billion dollars. Crop losses are primarily reduced by the use of resistant cultivars. Nematode populations are variable and have adapted to reproduce on resistant cultivars over time because resistance primarily traces to two soybean accessions. It is important to use diverse resistance sources to develop new nematode resistant cultivars. Soybean PI 494182 is a recent introduction from Japan and found to be resistant to multiple nematode populations. It is yellow seeded and maturity group 0. We have determined inheritance of resistance in PI 494182 using $F_{2:3}$ families derived from cross PI 494182 X cv. Skylla. Skylla is a susceptible parent. Three nematode populations, races 1, 3, and 5, corresponding to HG types 2.5.7, 0, and 2.5.7 were used to bioassay 162 $F_{2:3}$ families in greenhouse experiments. Based on Chi-square tests, a two-gene model is proposed for resistance to race 1 and a three-gene model is proposed for conditioning resistance to both races 3 and 5. Correlation coefficient analysis indicated that some genes conditioning resistance to races 1, 3, and 5 are shared or closely linked with each other. These results will be useful to soybean breeders for developing soybean cultivars for broad resistance to nematodes.

SCORM은 교육용 컨텐츠를 SCO라는 객체 단위로 공유하고 재사용하기 위한 국제적 표준이다. 그러나 유사 영역에서의 학습 컨텐츠 재사용시 컨텐츠의 일부분을 변경해야 할 경우에도 컨텐츠 원본을 수정해야 하는 문제점을 안고 있다. 따라서 이 논문에서는 이러한 문제점을 해결하기 위해 상속이 가능한 컨텐츠를 개발할 수 있는 I-SCO 모델을 제안한다. I-SCO 모델은 SCORM 기반 컨텐츠의 오버로딩과 오버라이딩을 통한 상속을 지원하여 컨텐츠의 재사용성을 증대시킨다. 실험에서는 제안한 I-SCO 모델을 설계 및 구현하여 ADL에서 배포하는 실행환경에서 실행시켜 봄으로써 컨텐츠의 상속 기능을 확인하고 I-SCO 모델의 타당성을 입증한다.

Recently, giant embryonic rice and functional rice food are preferred by more consumers, which are attributed to the fact that the embryo has high concentrations of essential amino acids, fatty acids, and vitamins relative to other parts of rice grains. In this report, the heredity and stability of giant embryo mutations in successive generations were analyzed regarding a giant embryonic line, 'P47', induced by T-DNA insertion and a $F_2$ population from a cross between 'P47' and 'Junam'. The mutant lines with increases of 1.5, 1.7 and 1.8 times on embryo length, width and 100-embryo weight to those of the control showed stable inheritance across three generations. The continuous frequency distributions of embryo size in the $F_2$ population showed that the embryo size is a quantitative trait of polygene controlled. In addition, wide range of transgressive segregations of six traits affecting embryo size confirmed exchange of genetic materials and recombination between genes controlling embryo size. Five giant embryo mutant lines selected from the $F_2$ population will be used for artificial selection and improvement of giant embryonic varieties.

배우자상속에 있어서 독일 등 다수 선진국들은 배우자 일방의 사망 시 부부재산제에 따른 청산을 통하여 생존배우자를 고정적으로 배우자상속분을 확보해줌과 동시에 철저히 보호를 하고 있는데, 우리나라 가족법에서는 다른 나라들에 비해 생존배우자에게 일정비율의 상속분만을 인정하고 있어 생존배우자의 상속권을 실질적으로 강화될 수 있는 방안이 필요하다고 본다. 특히 2014년 법무부 민법개정위원회의에서 현행법상 배우자 상속제도를 해결하기 위하여 제1008조의4 배우자의 선취분 조항과 제1008조의5 배우자의 선취분 침해에 있어서 회복청구권에 대한 조항신설이 논의 되어 국민들의 높은 호응이 있었음에도 불구하고, 생존배우자 법정상속분을 상향조정을 하게 되면 기업상속 등에 문제가 발생한다는 논리로 개정안은 입법예고도 못하는 상황에 이르게 되었다. 또한 초고령화사회에 살고 있는 생존배우자의 노후생활 보장과 직계비속과 공동으로 상속받는 경우 직계비속의 수에 따라 배우자의 상속분의 유동성 등이 문제점으로 대두되기 때문에 합리적인 생존배우자의 상속분 상향조정되는 입법안이 새롭게 시작되는 21대 국회에서 조속히 마련되기를 기원하는 차원에서 생존배우자의 효율적인 입법방안을 제시하고자 한다.
