The purpose of this study is to offer previous data for training of the better opticians and insuring substantiality of the education in junior college. The research groups consist of the professor of ophthalmic optics, spectacles wearers, opticians, graduates and students. The research nations are U.S.A in the North America, Germany in the Europe, Japan and Philippines in the Asia and Australia. The results are as follows, 1. The related educational systems to spectacles are generally the four years system. And the dispensing and optometry are divided in function. 2. The social recognitions change for opticians due to increase wearere and they require the opticians to study harder. 3. The relative respondents to education give support the extension of the education term. 4. The opticians demand that technical education are afforded to them. Because new materials are in the development stage and the spectacles wearers claim new information from opticians.

심성엽,金末文,이동건,문영희 嶺南大學校 基礎科學硏究所 1993 基礎科學硏究 Vol.13 No.-

Charge trapping in the insulator of a metal-oxide-semiconductor (MOS) structure strongly influences photocurrents resulting from electron photoinjection from gate into this insulator. These electric characteristics are investigated by Przewlocki method for determination of trapped charge distribution in the dielectric of a MOS structure. Silicon dioxide films were grown thermally in a dry oxygen ambient at 1000℃ to a thickness of 2000Å on (100) 6-9Ωcm p-type Si Wafers. As a result, it is found that the negative charge distribution is an exponential profile of decay lengthλ=9.907×10??cm and trapped charge density N。=3.912×10??cm-₃in the dielectric of this MOS structure.

이경구,이준호,권용욱,정태융,심희영,이상익 관동대학교 의과대학 의과학연구소 2005 關東醫大學術誌 Vol.9 No.1

Tension-free vaginal tape(TVT) has been widely used in the management of stress urinary incontinence(SUI), and has been applied to urge incontinence (UI). We evaluated and compared the outcomes between SUI and UI for patients who had undergone TVT. Patients were categorized into SUI(33 patients) and UI(26 patients). Before treatment, we asked about LUTSs using female bladder questionnaire. And we asked about sexual function. After treatment, the same questionnaires were repeated. During the postperative period, the objective and subjective success rate were evaluated. For operation outcome results, in SUI group there were 29 cases of cure (87.9%)and 2 of improvement(6.1%), and in UI group there were 20 cases of cure(76.9%)and 3 of improvement(11.5%) (p>0.05). The operation satisfaction rate of patients was 90.9% in SUI group and 84.6% in UI group(p>0.05). Improvement of sexual satisfaction occurred in 6(20.0%) of SUI group, and 3 (18.8%) of UI group, respectively(p>0.05). The objective success rate, satisfaction rate and sexual satisfaction of SUI patients did not significantly differ from the women with UI. Also, these results shows that TVT procedure improves some LUTSs in both groups. We consider the TVT procedure to be an effective treatment not for stress urinary incontinence but also urge incontinenece.

Sang Don Han(韓相敦),Don Koo Lee(李敦求),Sang Yung Shim(沈相榮),Sung Ho Hong(洪性昊),Sung In Shon(孫聖仁) 한국육종학회 1990 한국육종학회지 Vol.22 No.2

Interspecific hybrids between pitch pine and some southern pines were examined on their growth and morphological characteristics. The hybrid pines included in this study were Pinus rigida×P. taeda F₁, P. rigida×P. elliottii F₁, and P. rigida×P. echinata F₁, P. rigida×P. radiata F₁ and P. rigida×P. serotina F₁, which have been grown for more than 15-year-old. P. rigida×P. taeda F₁ showed the best growth in height, diameter, mean tree volume and stand volume per hectare among all hybrid pines at all 8 locations throughout the nation. The next best hybrid pines were P. rigida×P, elliottii F₁ and P. rigida×P. serotina F₁. However, P. rigida×P. radiatea F₁. and P. rigida×P. echinata F₁ rather grew poorer than pitch pine. Growth patterns of the hybrid pines were also compared among four different locations. In Daeduck, Chungnam and Wanju, Chonbuk, hybrid pines did not show and growth retardation after 20 years. Some morphological characteristics such as, bark thickness, the number of epicormic sprout, and various needle characteristics were significantly different among hybrid pine species. The fast growing P. rigida×P. taeda F₁ had the longest needle, thinnest bark, fewest epicormic sprout and the most straight stem. The greatest nubmer of stomata per 1㎟ was shown by P. rigida×P. taeda F₁, and followed by P. rigida×P. serotina F₁, P. rigida×P. elliottii F₁, P. rigida×P. radiata F₁ and P. rigida×P. eachinata F₁ in descending order.

Studies on Genetic Parameters and Gains Obtained from Open - Pollinated Progenies of Plus Trees of Pinus densiflora S . et Z . in Korea

Sang Yung Shim 한국산림과학회 1986 한국산림과학회지 Vol.72 No.1

Tree improvement and increase in the forest productivity are urgent in view of the fact that would forest covers are decreasing steadily while demands for woods are increasing annually. Breeding by selection based on the theory of quantative genetics has been recently applied to tree improvement in many countries. To maximize genetic gains and to establish effective and long term breeding strategy through estimation of genetic parameters, such as heritability, simple and genetic correlations and expected genetic gains, open-pollinated progenies of 58 selected plus trees of Pious densiflora S. et Z. were raised seeds collected in the fall of 1973 and outplanted at three localities, i.e., Kongiu, Wanju, and Naju. The progenies were evaluated at age 10 and the results were obtained as the following: 1. There were differences in height growth among locations mainly due to differences in soil nutrition. The Kongju plantation showed best mean height growth, 326.6 ㎝, and was followed by Wanju plantation with mean height of 317.8 ㎝ and the poorest height growth appeared in Naju plantation, showing the mean height, 200.8 ㎝. Therefore, open-opplinated progenies of Pious densiflora should be tested ar. a few more sites than the sites of this study in future. 2. Relaized genetic gains computed on the basis of control tree performance showed the highest value in stem straightness, and was followed by height and diameter at root collar, and the specific gravity which is the lowest value, when the best families were selected among the progenies. 3. Simple and genetic correlations among the characters were analysed and the two correlations showed the same trend. In both. simple and genetic correlations, significant positive correlation was shown between height and other characters such as diameter at root collar, stem strightness, crown width and number of branches per node, but there was negative correlation between stem straightness and diameter at root collar. Therefore strict selection criteria for stem. straightness should be practiced when diameter growth is considered as a major character for selection. 4. Age correlation was analysed for height growth to make early selection instead of waiting regular rotation age, and early selection for 10-yr-old progenies seems to be possible at age five. 5. Heritabilities of the characters studied were ranged from 0.493 to 0.687 on the family mean basis, and high heritabilities were Shown in the characters such as branch angle (0.687), diameter at root collar(0.607) and height growth(0.601). Heritabilities for individual tree basis were; ranged from 0.158 to 0.306, and high heritabilities were shown in the characters such as height growth (0.306), diameter at root collar(0.278) and branch angle(0.247). 6. Genetic gains were estimated for each character and 25 percents selection was considered. Mass selection and combined selection(individual selection/family) were taken into account. The gains were ranged from 19.9 to 21.5 percents for height growth, from 32.3 to 35.5 percents for stem straightness, and 21.4 percents for diameter at root collar in both selection methods.

Forestry Administration and Forestry Research in Korea

Sang Yung Shim 한국산림과학회 1987 한국산림과학회지 Vol.76 No.3

Korea is a small country with extremely high population density. Industrialization of the nation resulted GNP per capita of over 2,000$ in 1986 with an inevitable byproduct, high level of pollution in many areas. Forest land is note acknowledged as not only a wood production site but also an origin of much more important intangible values, water and clean air, soil conservation, and recreational and scenic values. Mostly devastated forest land from Korean War has been recovered under the strong afforestation drive from the government. The first Forest Development Plan was mostly reforestation phase and the second Forest Development Pan is foundation establishment phase. The third and later Plans are to enlarge economical forest and to maintain sustatined yield phase. Forestry administration as well as forest research certainly played a great role in successful accomplishment of two Forest Development Plans. Fur effective planning and accomplishment of the third Forest Development Plan close cooperation among policy makers, forest managers and research workers are mostly required.

Hematogeneous spread from tuberculous lesions of other parts of the body represent the origin of intracranial tuberculomas. In most series of the literature, the cerebellum has about two thirds and the cerebral hemispheres about one third of the intracranial tuberculomas. It may occurs as a single lesion, but multiple intracranial tuberculomas varies from 10% to 33% of the cases due to the hematogenous spread. Calcium deposits are rare, occurring in about 6% of cases. Ramamurthi and Varadarajan described the two types of the intracranial tuberculoma; 1. superficial and vascular type, produces early focal signs of increased intracranial pressure. 2. deep and avascular type, accoampained by signs of increased intracranial pressure. We have been experienced in one case of symmetrical and bilateral cerebellar tuberculomas probably originated from the pulmonary lesion.

Modulatory effect of ginseng total saponin on dopamine release and tyrosine hydroxylase gene expression induced by nicotine in the rat

Shim, In-Sop,Won, Je-Seong,Lee, Jin-Koo,Song, Dong-Keun,Kim, Sang-Eun,Huh, Sung-Oh,Kim, Yung-Hi,Suh, Hong-Won 경희대학교 동서의학연구소 2001 東西醫學硏究所 論文集 Vol.2000 No.-

Several studies have demonstrated that behavioral activation induced by psychostimulants is prevented by ginseng total saponin (GTS), which has been known to act on the central dopaminergic system. In an attempt to investigate whether the effect of GTS is through its inhibitory action on the elevated dopaminergic transmission, we examined the effect of GTS on nicotine-induced dopamine (DA) release in the nucleus accumbens (NA) of freecly moving rats using in vivo microdialysis. Systemic injection of nicotine (3 mg/kg; 1.p.) produced a mild increase in extracellular DA of dialysates samples in the NA (132 ± 13% over basal levels at the peak). GTS(100 mg/kg; i.p.) had no effect on resting levels of extracelluar DA. However, an increase in accumbens DA release produced by systemic nicotine was completely blocked by systemic pre-treatment with GTS (100 mg/kg; i.p.). In addition, the effect of GTS on nicotine-induced tyrosine hydroxylase (TH) and immediate early gene expression in ventral tegmental area (VTA) or NA regions was examined. A single injection of nicotine increased TH mRNA level at VTA region. GTS, which did not affect the basal TH mRNA expression, attenuated nicotine-induced TH mRNA expression. Nicotine slightly increased both c-fos and c-jun mRNA level and GTS, which did not affect the basal c-fos and c-jun mRNA expression, further enhanced nicotine-induced c-fos and c-jun mRNA level at both VTA and NA regions. Our results suggest that FTS may have an inhibitory action against nicotine-induced DA release in NA region and TH mRNA expression in VTA region. GTS may exert an potentiative effect on both c-fos and c-jun mRNA expression at NA region through inhibiting the release of DA in NA. ⓒ 2000 Elsevier Science Ireland Ltd. All rights reserved.

심성보,전용문,김광명,옥영철,이규웅 대한신경외과학회 1976 Journal of Korean neurosurgical society Vol.5 No.1

Malignant peripheral nerve tumors are very rare and derived from the neurofibromatosis in about 13%. There are two classes of malignant tumors in the peripheral nerves, one those of mesoblastic origin, is far most common and made up of malignant neurofibroma and much common fibrosarcoma, and metastasis in 20% of fibrosarcoma, and the other is neuroepithelial origin. These are characterized by increased cellularity, atypical from of cells, mitoses and invasiveness. The choice treatment is radical removal of the tumor, and not affected the prognosis by radiation or chemotherapy. We have been recently experienced of one case of malignant schwannoma on the cervical roots in a case of von Recklinhausen's disease.

심성보,신재학,전용문,김대조,옥영철,이규웅 대한신경외과학회 1976 Journal of Korean neurosurgical society Vol.5 No.2

Technetium 99 M pertechnetate has become a valuable material for the radioisotopic brain scan. This was introduced by Haper in 1963 and is now widely used in the medical field. The advantages are easy administeration, high count rate with potential for high speed scanning, absence of beta radiation and decreasing time for test. We used Siemens Scintimat 2 Scanner with a 3x2 inch Na(T1) crystal and 151-hole collimator in our study. 10 mci of Technetium 99 M was injected intravenously and obtained both lateral, anterior and posterior view in 80 cases of brain lesion from Mar. 75 to Sept. 76. The scans were classified as positive, negative and suspicious. The overall detection rate in '40 cases of brain tumors was 60%, especially high uptake in mengioma, malignant pituitary tumor, astrocytoma, metastatic brain tumor and acoustic neuroma. But in nontumorous diseases of the brain including CVA, head injury and hydrocephalus the uptake rate was a little value.
