정명선,김효정,류덕환 한국의류산업학회 2004 한국의류산업학회지 Vol.6 No.2

Loess was selected as one of the natural dyes and dye solution was extracted from it. With the dyes extracted from loess, the sample fabrics were dyed at 10, 20, and 30 minutes and then CuSO₄ was used to treat the dyed fabrics on the concentration of 3%, and 5%. Color difference and colorfastness of the sample fabrics with dyeing time and concentration of post-mordanted agent were analysed. The results were as follows: 1. Effective dying time was 20 minutes since any more dye up-take to the fabrics did not occur after that time. 2. There was distinctive dyeing effect according to whether post-mordanted method was done or not, but there was little effect between post-mordanted concentration of 3% and 5%. 3. There was no effect of the colorfastness on the post-mordanted concentration. The abrasion and laundering colorfastness of post-mordanted fabric samples was better than those of no post-mordanted fabric samples and the light colorfastness of the fabric samples was good regardless of post-mordanted method.

최덕규,박차훈,김태선 경운대학교 산업기술연구소 2002 産業技術硏究論文誌 Vol.5 No.1(B)

At the present time, the LCD (liquid crystal display) not only emitsless radiation and consumes less power, it also takes up less space allowing for a more comfortable work environment. This paper looks into characteristics of LCD's CCT. We propose the LUT (look-up table) which adjust the three primary colors'digital input value, for maintaining the fixed value of correlated color temperature. LCD's CCT is maintaining about 6500 K, which is the standard CCT of display systems. Moreover it is the same as the former LCD's luminance that LCD's with using the LUT. In addition, we confirm that the color reproducibility of LCD using the proposed LUT become much accurate than a conventional LCD.

石灰混合土의 다짐, 壓縮强度 및 耐久性에 대하여

都德鉉,金善柱 建國大學校附設農業資源開發硏究所 1985 農資源開發論集 Vol.10 No.-

Lime was mixed ti the five kinds of weathered Granite soils with different ratios and their characteristics of compaction, unconfined compressive strengrh and durability were investigated. The results obtained are as follows; 1. With the additon of lime, the optimum moisture content was increased and the maximum dry density showed the maximum value at optimum content of lime. 2. There were optimum lime contents which showed the maximum strength in the lime mixed weathered Granite soils and the more the amount of fine grain soil was, the less the optimum lime content. 3. The initial strength of the tested lime-soil was increased by the increment of the fine grain content and also showed high unconfined compressive strength in the coares grain soil by elapsing the curing period. 4. Because the lime reacts selectively, the unconfined compressive strength is not always high when the content of lime grain soil is abundant and there are some cases that the unconfined compressive strength of coarse grain soils with great compaction density is high. 5. The by-product gypsum is expected to change the soil texture with short period and also increase the unconfined compressive strength slightly. The lime magnesia plaster and the China clay are hard to expect to improve the unconfined compressive strength with short period but the improvement of soil texture could be expected when the curing period long. 6. The decrease of strength and the rate of weight loss caused by the repeatition of drying and wetting cycle were comparatively slow and specimens which the lime was mixed properly did not collapse after 20 cycle. 7. However the rate of decrement of strength by the repeatition of freezing and thawing cycle was high, slmost all specimens were collapsed within 4 cycle. 8. It is necessary to develope the way of studying in which examine the durabilty of lime mixed weathered Granite solis by measuring the amount of weight loss after the repeatition of drying and wetting or freezing and thawing cycles.

설수덕,이순재 동아대학교 생산기술연구소 2000 生産技術硏究所硏究論文集 Vol.5 No.1

Grounding agent is produced of blend both anion surface active agent and nonion surface active agent in the lubricant mixed by oleic acid and diethanol amine. Conversion ratio is proportionate to the reaction temperature and the composition of diethanol amine in lubricant mixture and it is the highest to 98% that the mol ratio of oleic acid : diethanol amine is to 1:3. The diminishing ratio of raw silk has no relation with the composition of bath anion a nd nonion surface active agent in the material test of grounding agent. It is excellent when the mol ratio of oleic acid and diethanol amine is the same mol ratio. Whiteness ratio is nearly constant regardless the composition of lubricant. The size of strength and elongation and cutting numbers have the inverse proportion to the composition of diethanol amine in lubricant. Modulus ratio has no relation with the density of grounding agent and is the best in 2.5%.

The plasma generally, ionized gas state, is the 4th state composed the universe. Generating the plasma artificially has been studied by spending energy and it has a lot of applications in human's life. There are several merits to modify the surface of polymer using plasma. Above all, plasma maintains the property of polymer because of it changes the property of surface only. Also, it doesn't use any organic solvents and it is the environment friendly process because of there are no waste under processing. Furthemore, in case of high-pressure plasma, it is possible that automated-processing continuously. In this study, we tried the reforming of surface to rise the adhesive strength between the material of polymer, experimented the rising of adhesive strength through a experiment of peel strenght by virtue of processing time and using gas, confirmed the change of polymer's surface through measuring the surface contact angle analyzer and scanning electron microscopy(SEM).

장덕선,전기영 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.14 No.4

This study was about how spontaneous physical activity had made and curiosity about what's the meaning to those exercisers. To understand the nature of exercise, participant observation was used as a qualitative method. Observing place was Backryonsan(Mountain) Hong Eun Dong Seodaemun Gu. Observing time was 5:30- 7:30 AM and researcher also participated. Observed situation was recorded in 1 or 2 hours so it could be very vivid actual. Daybreak exercise was analysed as one thing. and the place, activity and exerciser was systematized. Daybreak exercises were classified as gymnastics around Eun Pyong Jung, weight training in physical fitness place, pine trees in hillareas, small open area and people who walk or running mountain roads. From early 30 years old married women to over 70 years old men used Eun Pyong Jung as a exercising place and it took 15-20 minutes. Physical fitness place was for weight training and it was open to anybody and anytime. And also, there were people who used small open area and walk or running the mountain roads. Exercise group was spontaneously formed and very intimacy, so they wanted to have other activities. Gymnastic groups need a leader, naturally it could be a older man's role. These indigenous mass sport should consider the preservation of spontaneous exercise culture, protection of green zone, physical training equipment's maintenance and repair of neighboring park, the course of development of health promotion and fitness used by nature. Future study was searching what psychological meaning and benefits of exercise and pursuit the positive and negative aspects on exercise.

스포츠 성취동기와 목표 조망

장덕선,이동재 群山大學校 1993 論文集 Vol.20 No.-

동기와 성취행동을 이해하기 위한 이론적 접근으로서 과거 행동주의 심리학 이후 인지심리학으로의 동기 이론을 간략히 살펴보았다. 행동주의 심리학의 mechanistic 패턴이후 욕구성취이론과 Weiner의 귀인이론은 인지심리학의 새로운 시대를 열게 하였다. 귀인이론은 승리/패배의 결과에 대한 정서상태가 미래의 기대 즉, 성취행동에 영향을 준다는 것이다. 그후 동기는 정서, 기대, 가치가 혼합된 성취동기 접근법을 제안하고 있다. 자기효능감, 지각된 유능감, 성취목표조망들로 구성된 사회인지적 접근법이 이에 해당된다. 교실과 스포츠의 성취맥락에 작용하는 두가지 중요한 목표조망으로 Nicholls (1948a, 1989, 1992), Roberts, Duda (1992)는 과제참여와 자아참여를 채택하고 있다. 자아지향이 높은 사람이 사회적 과정에서 최선을 다하거나 기술향상을 더 고려하는 것으로 나타났다. 또한 지각된 능력, 귀인, 내적흥미 등이 목표조망의 개인차에 따라 성취동기의 사회화 과정에 영향을 줄 수 있다. 이러한 내용으로 성취행동의 이해를 위한 대략적인 흐름을 고찰하고 이에 대한 미래방향을 논의하였다. In sport, achievement behaviors are those behaviors witnessed when participants try harder, concentrate more, persist longer, pay more attention, perform better, choose to practice longer, and join or drop out of sporting activities. The study of motivation is the investigation of the energization and direction of behavior. When motivation matters, various theoretical models have been proposed as governing motivation and achievement behavior. Motivation theories may be viewed as being of a continuum rangion form mechanistic to cognitive, or organismic. However, among the many alternative approaches advocated, two major research traditions amy be edentified : need achievement and the cognitive approach. The social cognitive approach is built around expectancies and values that individuals attach to different goals and achievement activities, the major mini-theories utilited in sport and exercise are self-efficacy (Bandura, 1977a, 1986), perceived competence (Harter, 1975, 1980), and the various achievement goal perspectives (Dweck, 1986). A briefly discuss how each approach has used in sport. Sport investigation are presented which have begun to test assumptions embedded in social cognitive theories of achievement motivation. The study focus on three major issues, namely the relationship between goal perspectives on behavior in sport setting : and the correspondence between goal perspectives and the broader concept of values in the sport domain.

河德模,辛孝善 東國大學校 1974 論文集 Vol.13 No.-

This study was designed to investigate the change of chemical composition of the serum and urine in humans after the MSG administration. Healthy Korean adult men were used for experimental objects. The experimental groups were divided into three groups receiving, one, three and five gram dosages, respectively. These groups were investigated as to the change of chemical composition in the serum and urine 2 and 24 hours after the administration. These findings were compared with the pre-administration condition. The results obtained are summarized as follows: 1) Among all experimental groups, the pH value, the non-protein nitrogen and the protein nitrogen content in the serum showed no marked changes after the administration, as compared to before the administration. 2) Among all experimental groups, the ammonia-nitrogen content in the serum, as compared to before the administration, decreased 2 hours after the administration but the urea-nitrogen content increased. 3) among all experimental groups, the blood sugar content in the serum increased slightly 2 hours after the administration, but the cotnent returned to the same level as before the administration. 4) Among all experimental groups, the albumin, α_1-, α_2- and γ-globulin content in the serum protein after the administration, as compared to before the administration, showed no market changes each time but the β-globulin content increased slightly after the administration. 5) Among all experimental groups, the urea-nitrogen and ammonia-nitrogen content in the urine after the administration, as compared to before the administration, increased slightly but the creatine and creatinine content showed no marked changes each time.
