We tested fruits quality and skin coloration of two pear cultivar ‘Wonhwang’ and ‘Whasan’ produced by bagging with different kinds of paper bags in the Cheonan area, Chungnam Province, Korea. The fruits were bagged at 35, 45, 55 or 65 days after full bloom (DAFB) with 3 kinds of double layer paper bag which consisted of grey color, yellow color and newspaper for outer layer. The great extent of light interruption was observed in grey colored outer paperbag among three kinds of paperbag which showed only 0.46% of lowest light transmittance when compared with 43.7% and 40.0% of yellow paper and newspaper, respectively. The development of skin redness (a*) increased with the delay of bagging time in two pear cultivars. But the fruits treated at 65 DAFB showed uneven coloration and excessive development of redness which represented low fruit external appearance value. Uniform flesh firmness was attained at the fruits bagged with grey outer color paperbag regardless of bagging time, although the fruit quality indices including soluble solids and titratable acidity did not change significantly by using different kind of fruit bags and bagging time in two pear cultivar. Based on our results, it was explained that the grey-colored fruit bag had positive effect on the development of skin coloration without any detrimental effect on fruit quality factors in ‘Wonhwang’ and ‘Whasan’ pears.

船體 FRAME 製作時 熱加工이 强度 低下에 미치는 影響

임건호,윤한용 木浦大學校 工業技術硏究所 1999 工業技術硏究誌 Vol.9 No.-

In a ship frame manufacturing, for hot working by employed a gas welding machine without bender, the rate of strength reduction generally not considered dearly. In this study, tensile and fatigue test have been carried out by using specimens manufactured by hot working in the same way applied for at the shipyard. The results obtained from this study are as follows: 1. The static strength reduction of specimens by pre-heating and post-heating becomes not so large. On the other hand, that of specimens, by post-heating only or without pre and post-heating in significantly large. It means that the effect of the residual stress and the change of micro-structure appeared greatly in the course of hot working. 2. Fatigue life of specimens by hot-working is not only reduced greatly, but also shorted to the limit of 0.1 times according to a stress level. 3. In a ship Frame manufacturing, the strength reduction to the parts of bending working can be reduced to a minimum if pre and post-working have been done.

中世語의 形式名詞에 대하여

高永根 서울대학교 어학연구소 1982 語學硏究 Vol.18 No.1

It is generally recognized that the adequate description of the bound nouns occupies an important position in the study of the Korean grammatical structure. There are many bound nouns in Middle Korean like Present­day Korean. The characteristics of bound nouns have not been so far clarified accurately. The purpose of this paper is to study the identifying standard of bound nouns. The bound nouns in Present­day Korean could be applied to those of Middle Korean. The standards discussed are as follows: 1. The important features of bound nouns are exhibited in their occurrence between participle forms and particles. It distinguishes bound nouns from free nouns. Even though a bound noun­equivalent item is similiar to the corresponded free noun in form and meaning, if their word­classes are different from each other, they could be classified as a bound noun. The bound nouns could be combined with the pronouns and genitive markers: They are also directly attached to the nouns. In this case they function tentatively as particle. 2. Even though the forms of bound nouns are identical with each other, if they exhibit difference in meanings and structural aspects, they should be registered as an independent form respectively. But even though their meanings are a little different from each other, if their structural aspects are not different from each other, they are classified as the same item. It should be emphasized that structural aspect in the decision of grammatical units is more important than meaning.

철판가공 공정군에서 범용성이 높은 용접공정, 절단공정 및 프레스공정 등의 철판가공 공정에 대한 전과정평가를 수행하였다. 각 대상 공정군별 국내 공정가동량이 가장 큰 4개 업체 선정하여 전과정 목록 데이터베이스를 구축하였다. 용접공정의 세부 용접공정에는 gas metal arc welding(GMAW), flux cored arc welding(FCAW), submerged arc welding(SAW) 및 spot welding 등에 대한 전과정목록 데이터베이스가 구축되었다. 절단공정에는 플라즈마 절단 및 산소-아세틸렌 절단, 프레스에서 3500 가압력 톤 수 프레스의 전과정목록 데이터베이스가 구축되었다. 추가적으로 절단 및 프레스 공정에서는 데이타베이스의 활용도를 높이기 위해 각 기능단위별 투입물에 대한 상관관계를 토대로 환경부하계산식을 작성하였다. 전과정평가 수행결과 용접공정군의 경우 각 용접기법과 용접 모재의 종류별로 영향 범주에 따라 환경영향이 차이가 있었지만 모든 용접공정에서 무생물 자원고갈 범주가 50% 이상으로 전체 환경영향에 가장 기여도가 큰 것으로 나타났다. 절단공정군의 경우에는 공통적으로 생태독성 범주가 전체 환경영향에 55%이상으로 가장 기여도가 큰 것으로 나났다. 프레스공정은 무생물자원고갈 범주가 전체 환경영향에 80%이상으로 가장 기여도가 큰 것으로 나타났다. Environmental performance of teel sheet processing processes was investigated by implementing a Life Cycle Assessment(LCA). The inventory analysis was performed with data obtained from four major companies Cycle Assessment(LCA). The inventory analysis was performed with data obtained form four major companies within the country. The selected processes were welding, cutting and pressing process. In welding process, there were gas metal arc welding(GMAW), flux cored arc welding(FCAW), submerged arc welding(SAW) and spot welding. In cutting process, there were oxygen-acetylene cutting and oxygen-plasma cutting. In pressing process, there was 3500 ton press. Especially for cutting and pressing process, we made some equations with regard to each input such as electric power and mineral oil to activate the utilization of the life cycle inventory database. As for welding process, environmental impacts vary according to the kind of parents metal. However, the most significant impact was the abiotic resource depletion. In the case of cutting and pressing process, eco-toxicity and abiotic resource depletion were identified as the most contributing impact respectively.

學習障碍 槪念에 대한 理論的 接近

李槿溶 大邱大學校特殊敎育硏究所 1985 特殊敎育硏究 Vol.12 No.-

Though “learning disabillities”was lately established as an area of special education, the concepts of it are not new and the term has been used in applying to many other disabilities. The comprehensive and significant concepts of LD have not been established, and many theoretical approaches to the concepts of LD have been criticized for their lack of well-defined concepts. The weakness of the theoretical roles have been criticized in aspects of (1) the single factor or concept of LD (2) the different views among LD specialists and (3) the narrow-mindedness and isolation of the theories. Many theories of LD have been presented to established precise concepts. Adelman (1971) presented the interactional model and emphasized interactional functions among strengths, weakness and limitation including specific learning situational factors. Senf's information-integration theory is based on the cognitive psychology. The importance of this theorty has been accepted because it explains the complicated cognitions of human beings by means of information-processing approach. Satz and Nostrand focused on the change of the development of children's abilities, linguistic abilities and reading achievement. Ross (1976) inferred that the abilities of selective attention are the major factors to discriminate learning disabled children from normal children. Torgesen (1975) presumed that learning disabled children are inactive learners, and vellutino (1977) hypothesised that poor readers are not able to use linguistic cues because they are lack of the information about the labeling of words. Wiener and Cromer (1967) presented hieratical modle and explained reading disabilities with the hieratical causal relations. Because the characteristics of LD are very complicated, it is very difficult to establish the concepts of LD solely with a specific theory. We should concern about the cause of LD to prevent and to treat it, and should plan efficient programs on the basis of their behavioral characteristics. Presently, many Specialists are trying to approach the cognition-behavior psychological aspects of LD. It is believed that we'll be able to obtain concrete concepts of LD, when we approach it under a multidisciplinary system and try to combine them efficiently into connection with psychological areas.

高等學校 地理敎科에 對한 學生들의 選好度 分析

李健鏞 건국대학교 1988 장안지리 Vol.3 No.3

The purpose of the study is to analyze the preference to the subject of geography of high school students. The paper examines the preferences and opinions of students, in terms of the contents of the textbook, and teaching method of geography. Based on such analysis, this paper tried to explore the ways of increasing the decree of preference to the subject of geography in high school. For the study was a questionaire method used and the size of the sample survey was 480 students in third grade, male and female, of four academic high schools in Seoul. And they were composed of 120 students, male and female each, applying for the liberal arts department, and of 120 students, male and female each, applying for the science department. The result of the analysis of this study is as follows: Firstly, in case the students have to choose the two among the subjects of the social studies, they favor the general social studies and geography, on the other hand, when they are required to choose only one of them, geography is comparatively less favored than the other subjects of social studies the reason for choosing selective subjects for male students is determined by the aptitude of students, but in case of female students, it is determined by the possibility of getting a good score for qualifying entrance examination of university. Secondly, it is shown that the social studies are favored in the second grade in middle school, while geography is disliked in the first grade in high school. From the fact, the problem of the range and content of the subject of geography can be seen. Thirdly, the first most important reason why the subject is diliked is that it is not appropriate to their aptitude or consistent with their interests, and the second most important reason is that the contents of the subject is difficult and unreal. Fourthly, the degree of preference for teachers in charge of the subject of feography is high, and it depends not so much on the personality of teachers as on the teaching method or enthusiasm of teachers. Fifthly, teaching methods of geography has not yet developed very well, especdully the fold study and experiment tools. Sixthly, in terms of practical application of the education of geography, most students have thought that the knowledge of geography attained in high school is hardly applied to real life, and they are little interested in the facts about geographical events shown by mass media. As mentioned above, students have comparatively low degree of preference to the subject of geography. Based on suchanalysis the following problems are raised. 1. A certain educational policy should be established so that the problems of the entrance examination system that the subject of geography is just one of selective. 2. The content of the subject of geography should be restructured so that it may be suitable for the intellectual developmental stage of students and the subject should be taught continuously from the first grade in middle school to the third grade in high school. 3. Teachers should have professional Idea of the subject and teaching mathod. In addition, teachers should encoukage the student to enhance their intrinsie motivation through the inquaiy learning method and to be accordingly accustomed the self-paced learning strategy. By improving the problems mentioned above, the education of geography will contribute to humanistic education.

전건수,김유승,하재성,박준용,서정오 大韓成形外科學會 1993 Archives of Plastic Surgery Vol.20 No.3

Pressure sore is an area of ischemic tissue loss resulting from prolonged or often repeated pressure, usually over a bony prominence of body. Recently, the prevalence of pressure sore is major clinical problem, due to the increased number of patients with spinal cord injuries or longterm comatous patient after traffic, industrial accidents. The surgical principles in the treatment of pressure sores are total excision of the ulcer, scartissue, bursae, complete removal of all infected bone with recontouring of bony prominences to alleviate discrete pressure points and resurfacing and padding of the defects with healthy and well vascularized tissues. The sacral sore is the most common site for the development of pressure sore in Korea. We had experienced 14 cases who had received surgical treatments for sacral sores with transverse lumbosacral back flap. We obtained the following conclusions. Advantages 1)It is quick and easy procedure 2)The flap elevation itself is relatively bloodless 3)The donor defect is in a non-weight-bearing area 4)Muscle is not sacrified(possibly of importance in the ambulatory patient) 5)Surgical options are preserved in cases of recurrence(the flap itself may be reelevated and inset in some cases of recurrence) Disadvantages 1)It is lacking the bulky padding afforded by alternative musculocutaneous flaps 2)The vascularity of the flap tip is empirically less dependable than that of a musculocutaneous flap 3)The donor defect is large, cannot usually be closed primarily, and may prove of cosmetic concern

통일언어철학을 어떻게 세울 것인가?

고영근 경희대학교 민속학연구소 2000 한국의 민속과 문화 Vol.3 No.-

Before the Liberation, Korea had a language policy conforming to the hermeneutic language philosophy. South Korea kept the same philosophy after the Liberation, but it was different in North Korea. They accepted a new language philosophy tuned to Marx's dialectical materialism and have controlled the language policy based on Chuche language philosophy since late 1960's. With Chung-Il Kim as a new leader it remains almost the same. The only difference is that in the Sung-Il Kim age they were affected by materialism and took the language for the tools for construction and revolution while they now regard it as rules which reconstruct men as well as the society and nature. The hermeneutic language philosophy and Chuche language philosophy cannot be easily compatible, since idealism and materialism are confronted concepts. But if they step aside for coordination, they might result in a unified language philosophy. Generally speaking, South Korea has mainly been interested in theoretical problems rather than practical problems. On the other hand, North Korea gave priority to practical problems and made considerable achievement in the language purification. But there were some schools of South interested in the language purification and North Korea also had an experience of digging into theoretical problems till mid 1960's. If north and South accept each other's merits and integrate dialectically, we can frame a unified language philosophy. Meanwhile North and South have neglected the Chinese characters thus far. I think this is undesirable for the inheritance of tradition and the independent development of the Korean language. It may be emphasized that before we frame a unified language philosophy we should have Chinese characters and English alphabets coexit together at the subordinating position while we prioritize the Korean language and writing system.
