  • The purpose of this experiment was to investigate boron deficient symptom of sugar beet. Sugar beet affected by boron deficiency was anatomized and observed by microscope and electron microscope. The sugar beet plants affected onboron deficiencyu with water culture and those of the experimental farm alike contained a small amount of boron. The symptom of boron deficiency began to show dark-brown lines at the ventral suface of the basal part of petiole and then, in the ridge of young leaf, growing point became darkened due to necrosis. The leaf blade was wrinked severely and finally the growth was stunted. The boron deficiency began with necrosis of the epidermis of the ventral surface of the basal part of petiole, and parenchyma under it. Necrosis and disintegration of the ridge of young leaf began to take place and were expanded gradually. Electron microscopic examination of boron deficient sugar beet plants revealed that chloroplasts degenerated, and appeared to contain larger amounts of starch, also observed larger number of osmophilic granules. And they peculiarly were found polyhedral crystals in the certain deficient chloroplasts.

  • The purpose of this study was to analyze the joint torque of triple segmental system in golf driver swing. For this purpose, joint torque were calculated. In order to determine the load on the lumbar region, a triple segmental system was set for wrist, left shoulder and lumbar, torque working on the lumbar region were estimated. For this study, a total of 7 professional golfers were sampled, and then, their driver swings were recorded with two high-speed digital video cameras (180 frames/sec.) to be synthesized into 3-dimensional images and coordinated. Then, Eular's equation was used to produce some kinematic data, which were used to calculate joint torque with Newton's function. All data were calculated using LabVIEW 6.1 graphic program. The results of this study can be summarized as follows; It was found that the joint torque was generated in the direction opposite the target on wrist and shoulder during down swing, while in the direction towards the target on the lumbar region. During impact and release, the torque on the wrist joint was converted from the direction opposite the target to the direction towards the target, while the torque on the lumbar region was generated vice versa. The joints on the club-arm-shoulder were generated in the opposite direction at the beginning of down swing when the torque on the thorax-pelvis began to be generated, and then, the torque on the thorax-pelvis began to lower, while that on the club-arm-shoulder began to increase. Thus, a rapid decrease of the torque on the lumbar region linked to the low trunk acted to increase moment and joint torque on the arm-club region.

  • The reproductive cycle of the bitterling, Rhodeus uyekii was studied to observe the annual variations of gonadosomatic index(GSI), size frequency distribution of egg, ovipositor length and histological changes of gonad. GSI began to increase from February when the water temperature started to increase, and reached the maximum value in May, whereas it began to decrease from July and reached the minimum value in August which in the highest water temperature season. It began to incerase again but showed low value from September to November. The GSI remained stable thereafter. Monthly changes in GSI, ovipositor length, frequency of egg diameter and gonadal histology showed that the annual reproductive cycle was classified into the following successive phases : primary growing phase from September to November, quiescent phase in December, secondary growing and mature phase from January to February, ripe and spawning phase from March to June, and recovery and resting phase from July to August.

  • Researchers are persons who are destined to produce improved knowledge, with duty, responsibility and desire for overcoming limits of the existing knowledge in continuously changing natural and social environments. In addition, both drawing research outcomes 'contributing to the society' by tapping on 'researches convergent with other disciplines', to 'deducing meaningful research outcomes' and 'operating laboratories for fostering convergence talents', for the consistency of incessant researches are the momentum for convergence researchers to continue convergence researches. However, an irony fact is that 53.1% of convergence researchers respond that they began convergence researches from happenstantial momentum (a happenstantial talk with other majors)'. This study examined what was the momentum from which convergence researches began and what was the motive with which they have been consistently conducted and suggested how to continue convergence researches.

  • This study investigate the transition about Japanese national costume kimono. The prototype of the present kimono is a kosode. The origin of kosode dates back to the mid-Heian period, when this type of kimono served as the everyday wear of commoners and an undergarment for court nobles, both men and women. In the Muromachi period, particularly after the Onin war, the kosode began to be by people of all classes. In the Muromachi period, kosode consisted mainly of woven textiles. In the Momoyama period, kosode became very elaborate, employing such various techniques as tie-dyeing, embroidery, metallic leaf(surihaku) and free-hand painting. These were further combined resulting in such techniques as tsujigahana dyeing and nuihaku, which are now considered to epitomize Momoyama-period textile design. A category of kosode of the early Edo period, known as Keicho kosode, is fashioned mainly from black, white, or red figured satin(rinzu), or from figured satin segmented in these three colors. Books of kosode designs began to be published in the Kambun era, when the merchant class was becoming economically powerful, kosode began to reflect its taste. During its final stage of development in the late 17th and early 18th centuries, yuzen dyeing achieved wide acceptance. From the late 18th century toward the early 19th century, kosode worn by the merchant class underwent drastic changes, while those worn by the samurai class changed little. In the after the late 18th century, clear differences in design and decorative methods appeared between the kosode worn by rich merchants and those worn by middle and lower class merchants.

  • There has been 10 years since the Health Promotion Act was legislated. The government began to establish a health promotion fund on the basis of Health Promotion Act in 1995, and to manage and operate the fund from 1998. It is evaluated that health promotion program have had various outcomes in many aspects. First, there has been growing awareness of the impotance of health promotion through the establishment of Health Plan 2010 and the effort to actualize the Plan. Second, the importance of securing health equity and identifying health determinants have been recognized during the planning process of Health Plan 2010. Third, the health promotion program have mainly focused on improving healthy life style of the population. As a result, desirable health behavior change of the population could be expected from the result of 2005 National Health and Nutrition Survey. Fourth, public health centers began to play a crucial role in implementing health promotion programs, and began to build infrastructure for health promotion programs. Fifth, management efficiency of private health related organizations have been improved. Finally, training for health promotion personnel and their participation in the program could be the foundation for the higher level of outcome achievement from the health promotion programs. Important challenges for future health promotion would be identification of the determinants and risk factors of health, formulating plan of regional health promotion programs, building infrastructure for health promotion, creation of specific action model by public health center, development of health promotion program for the elderly, conducting research for evidence concerning major factors reducing the need for health care through prevention disease activities, and establishment of evaluation and feed back system for health promotion programs.

  • This study aims to examine the change of fish market(魚物市場) and inland brokers(客主, kaegju) on Gunsan(群山), (1899-1919). The increasement of productive capacity in the agriculture and the development of exchange economy in the late period of Chosun Dynasty activated the distribution of fishery products. As a result, the inland brokers who participated in the production and distribution of fishes grew largely. They made the basement of fishery modernization by providing the funds for the fisheries and making the national distribution network. But Japanese fishermen began to hold the domestic market as the Japan government supported legislatively and economically after the opening ports of Korea. On the contrary, the distribution of fishery products had the characteristics different from the production of some. The case of Gunsan which opened in 1899 showed these characteristics as Gunsan is a short distance from Kangkyung(江景), one of three biggest markets and was a base of fishery, That is to say, though the fishery merchants from Japan set up 'a fish market'(魚市場), they didn't hold the sales network on Gunsan, Because the inland brokers on Gunsan had a sales network and began the socio-economic movement. It goes without saying that the instability of price, the difficulties of charge and the racial taste difference in fish made the fish sales from Japan confronted with the difficulties. After Japanese Imperialism enforced the Company Law, the Market Regulation, the Chamber of Commerce Law before or after 1910, Korean inland brokers were disprited and Japanese 'fish market' began to grow largely. These phenomena appeared on Gunsan, too. Especially, the opening of a railway was the main factor which strengthened Japanese 'fish market'. After 1915, Japanese 'fish market' on Gunsan defeated the distribution network of inland brokers.

  • The purpose of this study is to suggest fundamental information about wearing method and production of brassiere, which is suitable for physiological hygiene and efficient action for elderly women. The subject is 418 elderly women aged 50∼69 years old. Data is processed by a computer(SAS) and is analyzed by using frequency, percentage, x²-test. The main results of this study are as follows. 1. Elderly women'weight and breast size are higher thant their younger counterparts'in their 20's, but the older and poorer women with more children have smaller weight and breast. Most of the elderly women feel that their breasts are drooped or falling apart. I fact, those elderly women who gave birth to more children have more drooped and wider breasts. The major type of elderly women'breast is the 'drooped breast' featured more by those elderly women who have more children. 2. Most of the elderly women began to wear the brassiere for the first time in their 20's the older women with more children began to wear the brassiere earlier, while those less educated and poorer began to protect their breasts with brassiere later. Many elderly women wear the brassiere to be protected from dirt, noise or look more neat, but day tend to wear the brassiere not all day around but at certain times, older, less educated and proper women with more children tend to use the brassiere for etiquette and less often. This group of elderly women feel tedious, stage or uncomfortable for the brassiere. 3. Most of the elderly women know about their brassiere size. Such variables as age, education and income are correlated positively with the interest in and consciousness of the brassiere size. All in all, the statistical distribution of elderly women's brassiere size is very wide, while most of them use 90A, 85A and 95A sizes. On the other hand, the most popular size of the under bust circumference is 85∼90cm, while their primary cup size is A.
