According to Korean's geographical features of Taek Li Ji, the best location for human settlements is on the vicinity of a stream among a stream, an river and a sea, and not far from a ridge. The researcher chose one of best village which is called Yougokmaeul in Bonghwa-Gun, Kyungsang-Do. This village was created a gathering village with the same surname, can be translated as a hen and the front mountain can be seen as a rooster in the view of the shape of geographical features. As it were, the shape of this village and the cultivated land seems to be an egg inside a nest of a parent's chicken in the respect of the analogy of the theory of P'ungsuchiri which is known as Feng Shui in China and geomancy in the western world, and to effect the defensive psychology of the living environment in the terrain inland. This village is the studying place, Suckchunjungsa as the lecturing and studying place for their following students within the Chunghadonchun, the studying Yougok village, and even the ritual place performing ancestral sacrifices and the first incoming ancestor's graves in the same geographical system. The house site of the first incoming resident is surrounded the countian and is located in the front of Backsulryount which is the main mountain through Moonsu-san in the branch mountain of Korean's mountain system. Backsulryoung which is to be seen as the white peak, is symbolized the head of a hen which is to relate to a mysterious turtle in the view of P'ungsuchiri. And the pavilion which is called Chungamjung is sited on the rock of a shape of turtle which is symbolized to live longer. In the section of the mountain and water, Lee Jung Hwan mentioned a living place near the mountain stream is the best residential area and a landscape which is composed by a stream between mountains make a pleasure spirit and a bright feeling and make a refined person. If one can reach in the graceful mountain make a pleasure split and a bright feeling and make a refined person. If one can reach in the graceful mountain half day away, this kind of place must be a best living residential area to live. But this village was structured all in one place. And one of the ideas tangibly reflected in traditional Korean society's view of life and nature is the seclusion based on the Taoism. This kind of a dreamy thoughts make a dream to keep the paradise in our ancestors' mind. This kind of utopia is Chunghadonchun which is structured 5 aspects from the utopian gate near the Samgaesuewon to the village. These 5aspects is expressed by some Confucian thoughts as a small cosmos individually. On the third aspects which is the center among these aspects, the Suckchunjungsa which was made a seclusion place to devoting himself to his studies with refined tastes. The word of Jiju-am, Gangpung-dae, Jaewol-dae and Biryoung-pock are all expressed to cultivate one's moral character and to seek the truth by the Confucius'theory through the nature.

The pedigree information and race records of 1,000 m finishing time of Jeju race horses at KRA were used to study the effect of amount of pedigree information and parental misidentification on the estimates of genetic parameters. The modified data sets were made at the range of 2.5 to 25% parental misidentifications or loss of parental information of individuals with an increment of 2.5 percent. For each incremental level, 20 randomly replicated data sets were obtained and analyzed by single-trait analysis with a DF-REML(AI) algorithm. As the rate of misidentification increased or the amount of pedigree information decreased, the estimates of fraction of additive genetics variance component gradually decreased almost linearly (p<0.05), while the estimated fractions of error variance and permanent environmental variance components gradually increased for the finishing time. Regression coefficients of the percentage amount of both parents' information loss and incorrect pedigree information on additive genetic variances were -0.079 and -0.114, respectively (p<0.01). The estimate of heritability decreased by 0.92% for one percent loss of both parents' information and 1.39% for one percent increase of both parental misidentifications of progeny (p<0.01). For the consideration of probable incorrect and missing parent information of progeny in this early population of Jeju horses, the estimates of additive genetic parameters would be biased downward about ten percent. This results indicate that the amount of pedigree information loss and misidentification of progeny would severely affect estimates of genetic parameters and would reduce genetic gains for selection in Jeju horse population.

The experiments were carried out to compare the growth characteristics of excised seminal roots in Japonica type, Indica- Japonica hybrids and its parents. Based on the modified culture medium by Kawata et al., several levels of pH. sucrose and casamino acid were varied in the culture media. The excised root length at 27$^{\circ}C$ incubator was little different between Japonica type and Indica-Japonica hybrids, but at 30$^{\circ}C$ incubator the excised root elongation of Indica-Japonica hybrids was much better than that of Japonica type. The dry matter weight of excised root in Indica- Japonica hybrids was significantly heavier than in Japonica type at both 27 and 30$^{\circ}C$ incubators. The difference of dry root weight between Japonica type and Indica- Japonica hybrids was caused from the number of lateral roots, especially the root numbers of 25 cm length. The main and lateral seminal root growth of Japonica type grew best at the lot of 0.2 percent casamino acid. However, the lots of 0 and 0.2 percent casamino acid showed good results in the main and lateral excised root growth. respectively of Indica-Japonica hydrids. The growth of excised roots was better in Indica-Japonica hybrids than in Japonica type at even various levels of pH, sucrose and casamino acid. Between the parents of Indica - Japonica hybrids, the excised root growth of Indica type was more predominant than that of Japonica type, and the effect of casamino acid on the excised root growth in the formar was similar to that of Indica type. This result indicated that the growth characteristics of excised seminal roots in Indica Japonica hybrids were derived from the parent, Indica type.

This study was carried out to calculate the genic values of days for flowering in commercial breeding lines of Korean hot pepper (Capsicum annuum L.). Two breeding lines of pepper '#2132' ($P_1$) early-flowering, and '#1308' ($P_2$) medium-late flowering, and their $F_1$ and $F_2$ generations were used in this study. By using partitioning method (Thseng and Hosokawa, 1971, 1972), it was possible to estimate, from the $F_2$ generations, the number of effective factor pairs differentiating the two parents. It was found out that the two parents were differentiated by two effective factor pairs, A:a and B:b. In the breeding lines used, the inheritance of days to flowering showed that the $F_1$ flowered a little earlier than the earlier flowering parent through the effect of over-dominance. However, $F_2$ flowered earlier or later than both parents through transgressive segregation. Conclusively, the magnitude of genic effects of A-a gene in flowering days was -13.81 days, and B-b gene was -6.73 days. The interaction between the two non-allelic factors using partitioning method was -5.26 days.

Background : The SCL began screening of newborns and high risk group blood spots with tandem mass spectrometry (MS/MS) in April 2001. Our goal was to determine approximate prevalence of metabolic disorders, optimization of decision criteria for estimation of preventive effect with early diagnosis. This report describes the ongoing effort to identify more than 30 metabolic disorders by MS/MS in South Korea. Methods : Blood spot was collected from day 2 to 30 (mostly from day 2 to 10) after birth for newborn. Blood spot of high risk group was from the pediatric patients in NICU, developmental delay, mental retardation, strong family history of metabolic disorders. One punch (3.2 mm ID) of dried blood spots was extracted with $150{\mu}L$ of methanol containing isotopically labelled amino acids (AA) and acylcarnitines (AC) internal standards. Butanolic HCl was added and incubated at $65^{\circ}C$ for 15 min. The butylated extract was introduced into the inlet of MS/MS. Neutral loss of m/z 102 and parent ion mode of m/z 85 were set for the analyses of AA and AC, respectively. Diagnosis was confirmed by repeating acylcarnitine profile, urine organic acid and plasma amino acid analysis, direct enzyme assay, or molecular testing. Results : Approximately 31,000 neonates and children were screened and the estimated prevalence (newborn/high risk group), sensitivity, specificity and recall rate amounted to 1:2384/1:2066, 96.55%, 99.98%, and 0.73%, respectively. Confirmed 28 (0.09%) multiple metabolic disorders (newborn/high risk) were as follows; 13 amino acid disorders [classical PKU (3/4), BH4 deficient-hyperphenylalaninemia (0/1), Citrullinemia (1/0), Homocystinuria (0/2), Hypermethioninemia (0/1), Tyrosinemia (1/0)], 8 organic acidurias [Propionic aciduria (2/1), Methylmalonic aciduria (0/1), Isovaleric aciduria (1/1), 3-methylcrotonylglycineuria (1/0), Glutaric aciduria type1 (1/0)], 7 fatty acid oxidation disorders [LCHAD def. (2/2), Mitochondrial TFP def. (0/1), VLCAD def. (1/0), LC3KT def. (0/1). Conclnsion : The relatively normal development of 10 patients with metabolic disorders among newborns (except for the expired) demonstrates the usefulness of newborn screening by MS/MS for early diagnosis and medical intervention. However, close coordination between the MS/MS screening laboratory and the metabolic clinic/biochmical geneticists is needed to determine proper decision of screening parameters, confirmation diagnosis, follow-up scheme and additional tests.

Purpose: This research aims to assess the effect of a single session of group education of hospice program at Seoul National University Hospital for the advanced and terminal cancer patients and their family members. Methods: Response to questionnaires from 89 participants were evaluated using SAS and CHISQ analysis. The questionnaires included the following items: 1) the characteristics of participants; 2) the characteristics of patients; 3) the difficulties of patient care; 4) the satisfaction with the program Results: The participants consist of 33 patients (37.5%) and 56 family members (56.2%). Diagnosis included mainly stomach, lung, breast, and colon cancer. Participants of family members consisted of spouse, parent, children, daughter-in-law, and siblings (in decreasing order). The participants were interested in the medical information, nutrition, pain and symptom management, and psychosocial adaptation. They had difficulties in emotional problem, nutrition and symptom management. Even though it was a single session of group education, the level of satisfaction was high (95%). Conclusion: This research shows that even the single session of the group education for the advanced and terminal cancer patients and their family members is very helpful by giving them the necessary information. In order to develop comprehensive care-giving services, more specific informations, more opportunities to participate in such sessions and longer question-answer time is required.

This study was carried out to estimate the degree of heterosis and heterobeltiosis, and the heritability and genetic correlation in F$_1$hybrid produced by reciprocal crosses between two six-rowed hulled barley (Gangbori and Olbori) and three six-rowed naked barley (Saechalssalbori, Saessalbori, and Moodeongssalbori). Heterosis was observed positively in traits such as cults length, spike length, awn length, leaf length, leaf width, number of spikes per plant, number of grains per spike, and 1000 grain weight. Heterosis and heterobeltiosis from the crosses with hulled barley as a material parent showed higher performance in culm length, leaf length, leaf width, number of spike per plant, number of grains per spike. The hulled grain characteristics is dominant over the naked one. The highest heritability was confirmed in leaf width with a value of 94.5% and overall high heritability was observed in most traits with the range from 76.7% to 94.5%. In an analysis of correlation coefficient, higher genetic correlations were observed between leaf length and number of spikes per plant(0.970), between cults length and number of grains per spike(0.963), and between awn length and leaf length(0.862) in the forward crosses in which hulled barley was maternal. In the reverse crosses, higher genetic correlation was observed between culm length and spike length(0.926), between awn length and leaf length(0.922), and between number of spikes per plant and number of grains per spike(0.713).

To date, the study of students with multicultural disabilities has been limited to language problems. The purpose of this study was to investigate the effects of communication between parents and professionals on the IEP and teaching strategies of students in multicultural special education in the United States. From 2015 to 2016, structural equation modeling was conducted using AMOS 21 based on data from 406 elementary, middle, and high school teachers who has experiencing of multicultural disabilities. The correlation coefficients between IEP and the variables affecting instructional strategies were significantly high between -044 and .489 as a whole. Especially, teaching strategy and communication with parents were relatively more effective than professional communication high correlation. In addition, with regard to the impact on IEP and teaching strategies, parental communication has been found to be closely related to IEP and teaching strategies. However, communication with professionals has a direct effect on teaching strategies. There was no significant correlation between parent and professional communication. The purpose of this study is to understand the importance of communication with parents of multicultural disabled students and their interest and opinions on children positively to IEP and teaching strategies so that teachers can communicate continuously.

This study empirically examines the effects of after-school self-care on children's development. More specifically, we examine whether the level of after-school self-care experiences that a child had during the 4 to 6 grade period affects the levels of school achievement, internalizing problem behaviors, externalizing problem behaviors, and delinquent behaviors during the child's middle school years. The study utilized the data from the Korea Welfare Panel Study's 1st and 4th year child supplementary surveys. The results show that the level of after-school self-care experiences negatively affects children's school achievement and internalizing problem behaviors. The study finds that, as the level of after-school self-care experiences increase, school achievement decreases and internalizing problem behaviors increase. The effects of after-school self-care on school achievement and internalizing behaviors were statistically significant even after controlling for the other variables that are known to be important factors on child development including child, parent, and family characteristics. The findings suggest that there is an independent effect of the level of after-school self-care on school achievement and internalizing problem behaviors. We also provide policy implications of the study. The policy considerations for latchkey children should include not only increasing the quantity of after-school programs, but also paying attention to the need of child development support programs beyond basic protection and care.
