Background : For cultivation of varieties of ginseng, the pure line selection method, which is to select the best among those cultivated in farms for pedigree breeding, replicated yield trials and regional adaptation trials before registering as a new variety, is widely used. Although there are 25 registered varieties of ginseng in Korea, the quality of ginseng is declining together with the amount of harvest being decreased by 15 - 20% due to the heat injuries and diseases from the warming & abnormal climate. Thus, the needs for development of disaster-resistant varieties with better chances of surviving through high temperature, salts and disease are increasing. Therefore, this study is to cultivate disaster-resistant varieties among those selected for their disaster tolerance and salt tolerance through regional adaptation trials. Methods and Results : As a result of examining the growth characteristics of the selected 2 - 5 year old varieties used in the study, among the 5-year old crops, Goryeo 4 and Eumseong 5 showed superior growth in both above and below aerial parts, and among the 4-year old crops, Eumseong 11 and Cheonryang showed superior growth while the growth in the below aerial parts were satisfactory in the order of Cheonryang > Eumseong 10 > Eumseong 11 > Eumseong 9. Among the 3-year old crops, the most superior growth in both above and below aerial parts was observed in Eumseong 14 with the weight of the below aerial part, root diameter and taproot length at 13.8 g, 11.8 ㎝ and 6.2 ㎝ respectively. Among the 2-year old crops, Eumseong 10 showed the most superior growth in both above and below aerial parts. Conclusion : Based on the above results, Goryeo 4 and Eumseong 5 among the 5-year old crops, Eumseong 11 among the 4-year old crops, Eumseong 14 among the 3-year old crops and Eumseon 10 among the 2-year old crops showed the most superior growth among the selected varieties. The growth characteristics of both above and below aerial parts in each year will continuously be monitored.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

In this thesis, we have described about application of amorphous magnetic ribbon of FeCoSiB compound to magnetic sensing device. As the samples of our experiment, we used a near zero-magnetostrictive amorphous magnetic ribbon of (Fe0.06Co0.94)79Si2.1B18.9 composition with its thickness of 26[㎛], its length of 5[㎝] and its width of 2[㎜], which was fabricated by rapidly quenching method. In order to improve the magnetic properties of the samples, we annealed them under magnetic field where the range of the crystallization temperature Tx and the Curie temperature Tc were 300~400[℃]. Then, by measuring them with X-ray diffraction(XRD) and vibrating sample megnetometer(VSM) analysis method. we found Tx≒451[℃] and Tc≒441[℃]. From the hysteresis curve of the finally annealed sample ribbon, we found the Large Bakhausen Jump(LBJ) effect at the reversal magnetization field Hw≒0.5[Oe]. This LBJ effect was also observed at the variation of the magnetic domain in the process of magnetization. Thus, it is proved that the amorphous magnetic ribbon of FeCoSiB compound can be use as a magnetic sensing device.

Dizziness is a balance disorder. Balance is made up of three biological functions ; sensory input, motor output, and biomechanical component. Sensory input is made up of vestibular, visual, and somatosensory input. The EquiTest System is a tool to evaluate the degree of the vestibular, visual, and somatosensory dysfunction in dizziness and it’s technique is called computerized dynamic posturography(CDP) to analyze the patient’s ability to maintain balance in dizziness. We investigated Korean healthy population and dizziness patients to study the degree of the vestibular, visual, and somatosensory dysfunction with EquiTest System CDP. The results of this study were as follows 1. The control group was 112 Korean Healthy population with a mean age of 40±19 years. In SOT, the ranged of median equilibrium scores were 93, 91, 92, 80, 72, 68 from condition 1 to 6, respectively. In sensory ratio study, the mean somatosensory ratio was 98, visual ratio was 86, vestibular ratio were 77. 2. The patients group was 324 dizziness patients with a mean age 42±17 who visited Dankook University Hospital from January 1996 to December 1997. 3. Vestibular, visual, and somatosensory dysfunctions in the dizzy patients were occurred in 169(52%), 65(20%), 19(6%) cases, respectively. 4. Combined vestibular and visual dysfunction, vestibular and somatosensory dysfunction, vestibular and visual and somatosensory dysfunction in the dizzy patients occurred in 42(13%), 16(5%), 13(4%) cases, respectively.

본 연구의 목적은 도재의 표면처리가 인장접착강도에 어떠한 영향을 미치는가를 알아보는 것이었다. 120개의 도재시편을 각 군당 10개씩 12군으로 나눈 후, 1군은 표면처리를 하지않았고, 2군에서 5군까지는 단독표면처리를 6군에서 12군까지는 복합으로 표면처리를 시행하였으며 그후 교정용 레진으로 통상적인 방법에 따라 브라켓을 접착하고나서 각 군의 인장접착강도를 측정하여 다음과 같은 결론을 얻었다. 1. 모든 단독표면처리군(G2,G3,G4,G5)은 표면처리를 하지않은 군(G1)보다 인장접착강도가 통계적으로 유의성 있는 증가(p<0.05)를 나타내었으며, 단독표면처리군 중 샌드블라트팅군(G5)의 인장접착강도가 10.34±2.50MPa로 가장 높았다. 2. 복합표면처리군(G6,G7,G8,G9,,G10,G11,G12)에서 9-11,5MPa의 인장접착강도를 나타내었고 이들 상호간에는 통계적으로 유의차가 없었다. 3. 단독표면처리군 중 샌드블라스팅군(G5)은 복합표면처리군(G6-G12)과 통계적으로 유의차가 없었다. The purpose of this study was to evaluate the effect of surface treatment of porcelain on tensile bond strength. To accomplish this purpose, this study was carried out with 120 samples which were divided into 12 groups with each 10 samples, and the first group was not surface treated, groups 2 through 5 underwent single surface treatment and groups 6 through 12 underwent compound surface treatment. The results were as follows: 1. In statistic, all the single surface-treated groups showed higher tensile bond strength than the non surface-treated group and the sandblasted group showed the highest tensile bond strength as 10.34±2.50MPa. 2. All the compound surface-treated groups showed no noticeable difference in the tensile bond strength(9-11.5MPa). 3. In statistic, no significant difference was found between the sandblasted group and the compound surface-treated groups. 4. There was no fracture of porcelain while testing in this study. Above study demonstrated that compound surface treatment or sandblasing, if used single surface treatment, should be employed to guarantee successful clinical application.
