This study was to identify the orchid mycorrhizal fungi and to test whether the orchid plants antificially inoculated with this fungus showed better growth them uninoculated plants. Symbioses in the root cells of the native plants of Cymbidium goeringii collected were observed and the digestive forms of peletons were also observed in various native roots. Two types of hyphae, thick $(7{\sim}10\;{\mu}m)$ and thin $(2{\sim}4\;{\mu}m)$ in thickness, were conclusively found to be from various native orchid roots. The symbiotic fungus was isolated by several agars and identified as a Rhizoctonia repens or a R. endophytica var. endophytica. Symbioses on the plantlets of C. karnan and Cymbidium hybrid 'Onomoron' were evaluated as the isolates inoculated on oatmeal agars. The growth of plantlets were measured with the formations of mycorrhizae in the roots. R. repens was shown to be the better isolate than the other in growth stimulation of plantlets on oatmeal agars when grown for two months. The two types of hyphae in the root cells under nature were speculated from the different fungal isolates of Rhizoctonia. Further isolates would be needed for application works for the orchid industries.

The research was conducted to find optimal habitats of warm-temperate evergreen broad-leaved trees, and to investigate climate factors to determine their distribution using classification tree (CT) analysis. The warm-temperate evergreen broad-leaved trees model (EG-model) constructed by CT analysis showed that Mean minimum temperature of the coldest month (TMC) is a major climate factor in determining distribution of warm-temperate evergreen broad-leaved trees. The areas above the $-5.95^{\circ}C$ of TMC revealed the optimal habitats of the trees. The coldest month mean temperature (CMT) equitable to $-5.95^{\circ}C$ of TMC is $-1.7^{\circ}C$, which is lower than $-1^{\circ}C$ of CMT of warm-temperate evergreen broad-leaved trees. Suitable habitats were defined for warm-temperate evergreen broad-leaved trees in Korea. These habitats were classified into two areas according to the value of TMC. One area with more than$-5.95^{\circ}C$ of TMC was favorable to trees if the summer precipitation (PRS) is above 826.5mm; the other one with less than $-5.95^{\circ}C$ of TMC was favorable if PRS is above 1219mm. These favorable conditions of habitats were similar to those of warm-temperate evergreen broad-leaved trees in Japan. We figured out from these results that distribution of warm-temperate evergreen broad-leaved trees were expanded to inland areas of southern parts of Korean peninsula, and ares with the higher latitude. Finally, the northern limits of warm-temperate evergreen broad-leaved trees might be adjusted accordingly.

Purpose: The purpose of this study was to explore the perception of infertile women on the use of the national support program that provides medical expense aid to infertile couples. Methods: Thirty Korean infertile women participated in five focus groups. Data were collected from January to August 2014. After obtaining permission from the participants, each session of the focus group was audio-taped and transcribed. The responses were analyzed using qualitative content analysis. Results: The main themes identified from the sessions with the participants were "feeling thankful for the reliable support program," "feeling happy or unhappy," "enduring inconveniences," and "hoping for a more comprehensive support service." Although most of the participants perceived the benefits of the national support service positively, they stated that the service was not comprehensive because it did not cover all the medical expenses for tests and other medical treatments. Conclusion: The benefits given to infertile couples by the program should be increased by covering all the medical expenses, expanding its criteria to include more eligible candidates, and by including special leave benefits for working women. Furthermore, it is essential to take measures for infertility prevention at the individual and national policy levels.

It was observed in the Subfertility Cases that Customized yinyang Balance Appliance (CBA) and Balancing Upper Cervical Alignment Technique of functional cerebrospinal therapy (FCST) for meridian and neurologic yinyang balance are theraputic. Four Subfertility cases were managed with the CBA, combined with acupuncture and herb-medicine. The other cases were managed with the Balacing Upper Cervical Alignment Technique, combined with acupuncture and herb-medicine. Clinical outcome measurement was based on subjective measures and clinical observations. Patients showed positive changes in subjective symptoms after the treatment and these effects maintained over the follow-up period. And each patient gave a birth to a male/female child. Further clinical and biological research with FCST therapy on hormone-related disordres is expected.

Therapeutic effect of Customized yinyang Balancing Appliance (CBA) and Balancing upper cervical alignment technique of Functional Cerebrospinal Therapy (FCST) for the balance of meridian and neurologic system was observed with regard to subfertility, a difficulty in fertility. One subfertility case was managed with the CBA, combined with acupuncture and herbal medicine. The other case was managed with the balacing upper cervical alignment technique, combined with acupuncture and herb-medicine. Clinical outcome measurement was based on subjective measures and clinical observations. Patients showed positive changes in subjective symptoms after the treatment and these effects were maintained over the follow-up period. And each patient gave a birth to a male child. Further clinical and biological research on FCST is expected.

본 논문에서는 각 광원의 위치에 대해 미리 구한 라디안스 맵에 시간-색 공간에서의 반사요소 분리방법을 적용하여 난반사 라디안스 맵과 거울반사 라디안스 맵을 구한다. 필셀 BRDF를 얻기 위한 입력으로 반사요소가 분리된 라디안스 맵을 사용하였다. 따라서, 광원의 조작에 대해 난반사와 거울반사 이미지를 각각 제어할 수 있다. 시간-색 공간에서의 반사요소 분리방법을 사용함으로써, 이미지의 전역 정보가 아니라 지역 정보만을 이용한 반사요소 분리가 가능하다.

반사광은 표면에 대한 다양한 정보를 포함하고 있다. 반사광 속에서 표면의 거칠기 정보를 알아내 기 위한 노력이 계속되었고, 이를 통해 여러 표면 거칠기 측정법 중에서도 인프로세스 측정에 큰 장 점이 있는 것으로 밝혀졌다. 알려진 바로는 하나의 반사광을 정반사 성분와 난반사 성분으로 구분할 수 있으며 정반사 성분은 광 강도가, 난반사 성분은 광 분포가 중요하다. 매끈한 면에서는 정반사 성분이 지배적이며, 거친 면에서는 난반사 성분이 지배적이고, 그 중간 단계의 면에서는 두 성분이 합해져서 동시에 나타난다.(중략)

bIn this paper, built-in self-repair(BISR) is proposed for semiconductor memories. BISR is consisted of BIST(Buit-in self-test) and BIRU(Built-In Remapping Uint). BIST circuits are required not oがy to detect the presence of faults but also to specify their locations for repair. The memory rows are virtually divided into row blocks and reconfiguration is performed at the row block level instead of the traditional row level. According to the experimental result, we can verify algorithm for replacement of faulty cell.

A combination of ultraviolet irradiation and egg rotation was applied to Korean frogs to study the mechanisms of the establishment of the dorsal-ventral polarity. Rotation of the uncleaved egg was capable of preventing the characteristic syndromes associated with UV irradiation. As well, brief rotation of the egg before cleavage relocates the site of dorsal lip to a novel location in the embryo at gastrula stage. That is, the dorsal lip appeared on the opposite side to gravity at the rotation of the egg. Above results were discussed with the informations obtained from other anuran and urodele species, and were interpreted in terms of regulating mechanisms for early embryogenesis.

전반사는 물체의 사실적인 모습을 나타내는데 중요한 요소이지만 컴퓨터 비전에서는 처리하기 어려운 장애 요소이다. 본 논문에서는 영상기반 재조명을 위하여 조명 조건이 다른 복수의 영상으로부터 전반사 성분과 난반사 성분을 분리하는 효과적인 알고리즘을 제안한다. 이 알고리즘은 전반사 성분이 존재하는 영상과 난반사 성분만이 존재하는 영상에 대하여 난반사 성분의 RGB 값은 서희 비율을 유지하면서 변한다는 성질을 이용하여 전반사 성분을 분리한다. 그리고 실험을 통하여 이 알고리즘의 유효성을 확인하였다.
