Factors affecting the survival of out planted Cryptomena and Japaneses Cypress seedlings. (I) - Especially on the drying and water soaking duration ­ There are often the cases of poor survival percentage for the economic forest establishments of Cryplomeria japonica D. Don. and Chamaecyparis obtusa End. This study was carried out to investigate the survival factors of both 1-1 seedlings and Cryptomena cutting Seedlings by room drying conditions, day drying conditions, OED green water soaking treatment and drying duration at the forest nursery of Chonnam National University from February to September. 1979. The results are as follows: 1. From 11 a.m. to 3 p.m. fluctuation in then moisture contents(MC) rapidly decreased and M.C. fluctuation in indoor until 5 p.m. showed the same results with the amount of an hour fluctuation in outdoor. 2. M.C. fluctuations between OED green and non-treatment of these seedlings were silghtly different. 3. The survival percentage of OED green and non-treatment of seedlings were highly significant in the room drying conditions and the day drying conditions respectively The effects of water soaking treatment on rooting was negligible. The survival percentage of seedlings of OED green was higher than that of non-treatment. 4. Although survival percentage of Japanese Cypress was almost in accord with Cryptomena, the power of resistance to drying was lower m Japanese Cypress than m Cryptomeria. 5. Compared with Cryptomena seedlings the survival percentage of Cryptomeria cutting seedlings was higher and not influenced at all in case of being drying for two hours; but it was highly significant in interactions between the drying time and the water soaking time. 6. When Cryptomena and Japanese Cypress seedling become drying in indoor for four days, the survival percentage remarkably reduced after two days and also was highly significant among numbers of drying days.

이정석,오광인 ( Jyung Seuk Lee,Kwang In Oh ) 한국산림과학회 1978 한국산림과학회지 Vol.40 No.1

This study was carried out to determine the proper transplanting time of Platanus occidentalis L. (plane tree, sycamore) with 5 to 6 ㎝ and 25 to 30 ㎝ in diameter of breast height at the forest nursery of Chonnam National University in 1977. For that purpose, the experiment of the time of transplantation, and the moisture content and soluble sugar were analysed. The results are as follows: 1. Both its rooting and growth were slightly different in the period of January to early April (before bud-break), but remarkably declined after its bud-break (mid-April to May). 2. And also, its moisture content and soluble sugar were slightly different (January to early April), but, on the other hand, considerably increased in the content of moisture and sharply decreased in soluble sugar after bud-break (mid-April to May). 3. In comparision with hcalthy trees, rooting and growth of trees infected with Cankers were unusually retarded and its moisture content and soluble sugar were much less. 4. The proper time to plant sycamore was recognized to be the period of November to March, since the higher amounts of soluble sugar and the lesser amounts of moisture in that period. 5. The sudden exposure to the sun of the boles of diseased and wounded trees could be in death in case of sun-scald on the side of south-west. 6. Pruning wounds should be treated with an antiseptic, as soon as they are made, to prevent entrance of decay or disease while the wound is healing. 7. The wound and sun-scald can be presented by covering the trunk with straw ropes before transplantations.

실험쥐 해마 절편 배양에서 성숙기에 따른 c-Jun 단백발현 양상과 전기적 발작으로 인한 신경원 손상 정도에 관한 연구

채수안(Soo Ahn Chae),이광인(Kwang In Lee),최응상(Eung Sang Choi) 대한소아신경학회 2003 대한소아신경학회지 Vol.11 No.2

목 적 : 구조적 및 전기적 발작 후의 c-Jun 단백발현의 차이가 미성숙 및 성숙 뇌사이의 발작으로 인한 신경원 손상의 차이를 설명할 수 있는지 알아보고자 본 연구를 시행하였다. 방 법 : 생후 8일된 실험쥐에서 해마의 기관형적 절편배양이 준비되었다. 배양 7일과 14일된 해마조직을 대상으로 실험을 시행하였다. 전기생리학적 실험은 Schaffer collaterals에 1 sec stimulus train(60 Hz, 0.1 msec rectangular pulses)을 가한 후 CA1에서 afterdischarge(AD)를 기록하였다. 전기생리학적 실험 후, 배양 조직을 배양기에 되돌려 놓고 신경원 손상 정도를 연속적으로 관찰하였다. 신경원 손상을 가리키는 PI 형광발현의 강도는 2 mM NMDA로 유발시킨 총 신경원 손상에 대한 백분율로 수량화 하였다. 본질적 및 전기자극 후의 c-Jun 단백질 발현 양상을 알아보기 위하여 Western blot을 시행하였다. 결 과 : 전기적 발작 후 24, 48, 72시간 경과시점의 CA1와 CA3 부위의 신경원 손상은 배양 7일된 미성숙 해마조직이 배양 14일된 성숙 해마조직 보다 의미있게 낮았다. 미성숙 배양 해마조직의 전기적 자극을 가하지 않아 구조적 c-Jun 단백발현이 성숙 배양 해마조직보다 의미있게 높았다. 미성숙과 성숙 배양 해마조직간 전기적 자극 후의 c-Jun 발현 정도는 의미 있는 차이가 없었다. 결 론 : 미성숙 배양 해마조직의 높은 구조적 c-Jun 발현이 발작으로 인한 차후 c-Jun 발현을 억제함으로서 미성숙 배양 해마조직이 성숙 배양 해마조직보다 발작으로 인한 신경원 손상이 미약한 결과를 가져온다고 생각한다. Purpose : Immaure brain is more resistant to seizure-induced neuronal damage than the adult brain in animal study. Immediate early genes such as c-jun play a critical role in neuronal damage. Therefore, we hypothesized that the difference of constitutive and electrically stimulated c-Jun expression would explain the difference in neuronal damage from seizures between immature and mature explant culture. Methods : Seven and 14 days-in-vitro(DIV) hippocampal explant cultures derived from 8-day-old rat pups were used. Extracellular field recording was done in cultures. A 1-sec stimulus train(60 Hz, 0.1 msec rectangular pulses) was applied to the Schaffer collaterals, and the afterdischarge was recorded in CA1 pyramidal layer. Cultures were returned to the incubator and observed serially. Intensity of propidium iodide fluorescence indicative of neuronal damage was quantitated as percent of total damage induced by 2 mM NMDA. Proteins extracted from individual cultures were analyzed by Western blot. Results : Constitutive c-Jun protein expression at 7 DIV was higher than that at 14 DIV. There was not a significant difference of c-Jun expression between the 7 DIV and 14 DIV cultures after electrical stimulation. Neuronal damage after electrical stimulation in the hippocampus at 7 DIV was significantly lower than at 14 DIV. Conclusion : The results show reduced neuronal injury from seizures in more immature culture. However, constitutive expression of c-Jun protein was higher. Higher constitutive expression may inhibit further induction of c-Jun from seizures and thus result in less severe neuronal injury.

This study is aimed to find out the conception of planarity in Modern Architecture. Some architecture historians such as Hildebrand and Schmarsow indicated the planarity by which new idea of space in architecture was made. The characteristics of the planar was embodied and developed through the proclamation of the ideology and their works in the avant-garde art movement of Cubism and Neoplasticism. The planarity in modern architecture was embodied from various aspects -the perception of space, the pictorial art and the metaphysics- by means of imaginary plane, superposition of planes, oscillation of plane, deconstruction of mass and elimination of natural color.

MRO·사무용품 프랜차이즈 본사와 가맹점 간의 관계가 가맹점 만족도와 경영성과에 미치는 영향

김광인(Kim, Kwang In),김승철(Kim, Seung Chul),이태원(Lee, Taewon) 글로벌경영학회 2020 글로벌경영학회지 Vol.17 No.6

MRO·사무용품 프랜차이즈 산업은 많은 발전을 이루었으나 본사와 가맹점 간의 경영활동상에 부실한 경영, 동종업종의 과도한 경쟁, 유통 인프라의 부족과 의사소통의 부재와 서로 간 의견 차이로 인해 많은 문제점이 발생하면서 갈등을 야기하고 있다. 이에 대해 본 연구는 대표적인 국내 MRO·사무용품 프랜차이즈 가맹점을 대상으로 설문을 조사하여 갈등 해소 방법을 찾고 실증분석을 하였다. 본 연구는 MRO·사무용품 프랜차이즈 본사와 가맹점 간에 영향을 받을 수 있는 관계 요인을 정립하고 분석하는데 주요한 의의와 목적이 있다. 실증 검증은 MRO·사무용품 프랜차이즈 가맹점을 대상으로 가맹점 시각에서 진행하였다. 이에 따라 프랜차이즈 본사와 가맹점 간 소통, 갈등이 결속에 어떠한 영향을 미치는지를 실증 검증을 통해 살펴보았고 관계 결속에 따라 만족도와 경영성과에 어떠한 영향을 미치는지도 분석하였다. 실증 분석 연구 결과는 갈등은 소통이 원활하면 갈등은 감소하는 것으로 나타났고, 결속은 원활한 소통과 갈등이 감소하면 결속이 강화됨을 알 수 있었다. 결속이 강화되면 만족도와 경영성과에 긍정적인 영향을 미치는 것으로 나타났으며 본사와 가맹점 간에 원활한 결속 관계가 만족도와 경영성과를 높이는 결과로 나타났다. 본 연구의 시사점으로는 MRO·사무용품 프랜차이즈 본사는 가맹점과 원활한 관계를 위해서는 가맹점과 수시로 의사소통을 하고 갈등을 저해하는 요인을 제거하는 데 노력하고 상호 간 배려하는 자세가 필요하다. 이러한 실증연구 결과는 대부분의 프랜차이즈 산업의 선행연구는 외식과 서비스 프랜차이즈 산업이었으나 이번의 연구는 MRO·사무용품 프랜차이즈 산업의 스펙트럼(spectrum)을 넓히는 계기가 되었다. 또한, MRO·사무용품 프랜차이즈 산업에 성공적인 관계에 근간이 되기를 기대한다. Although MRO-office supplies franchise industry has seen immense progress, there exists various conflicts and problems caused as a result of mismanagement, excessive competition, lack of distribution infrastructure, poor communication, and opinion differences. In this study, a survey was conducted on leading domestic MRO-office supply franchisees to find ways to resolve conflicts through an empirical analysis. This study has a crucial aim and purpose in establishing and analyzing the relevant factors that may affect the relationship between MRO-office supplies franchisor and franchisees. . Accordingly, we examined how the communication and conflicts between franchisor and franchisees affect solidarity of the parties through this empirical verification and evaluated how these affect satisfaction and management performance according to the solidarity of the parties. The results of this empirical study reveal that prior researches of most franchise industries were performed on dining and service franchise industries, but this study served as an opportunity to expand the spectrum of franchise industries. In addition, this study hopes to be a new foundation to enable future development of successful relationships in the MRO-office supplies franchise industries.

This study is aimed to analyze the method of movement expression in the Space-Time of Modern Visual Art. According to the results of analysis. the following is obtained. (1) The still object is perceived by the sense or optical illusion, and its whole image is made through the information processing prodedure. The concept of Space-Time is integrated into the constructivist works by the composition of image through transforming the position of the fundamental geometry and projecting it. (2) The traditional notion that the work of art is still concept of is changed. The movement of observer is caused by inducing the direction and concept of time through the object in three dimensional space.

The purpose of this study is to find out organizing strategy of de-composition works in modern plastic arts. Through investigating the development process of De Stijl painters and Rietveld's early works and analyzing the composition and disposition type of elements such as point, line, plane, color in the selected works, we can draw some conclusions. First, Rietveld pursues the dissolution of traditional volume and the de-composition of elements as Mondrian does through crossing-connection of three listels with quadrangular section. Second, Rietveld reorganized de-composition elements with detached lines and color planes. Third, Rietveld experimented possibility of new plastic space through displacing elements, opening space, making anti-gravity space.
