권혁남,이용희,김종오 국립중앙박물관 2000 박물관보존과학 Vol.2 No.-

국립중앙박물관에서는 국내외에서 구입한 유물들을 전시하기 위하여 보존처리를 실시하였다. 처리유물은 금속제 유물을 비롯하여 목제, 회화, 목·칠기 등 다양한데, 이중 금속유물 42점의 보존처리 내용을 재질별로 소개하였다. 유물의 현재 상태를 파악하기 위해 현미경 조사 및 X-선 촬영을 실시하였으며 재질에 따라 이물질 제거 방법, 안정화 처리 방법 등의 처리 방향을 설정하였다. 또한 역사적 자료를 보존하고 일반인들에게 전시할 수 있는 조치를 취하였다. For exhibition, conducted conservation treatment for a variety of collections acquired at home and abroad such as metallic objects, wooden-ware, paintings and lacquer-ware. Conservation treatment methods for 42 metallic objects were introduced for material types. X-ray and microscopic method were used to identify the current state of the collections and in some case if necessary, various foreign particle removing and stabilization method were used depending on material type. Historical data were stored and exhibited to public.

The purpose of this study was undertaken to determine the effects of orthognathic surgery on speech. The hyposis stated herein is that functional behaviors of the dentofacial complex, such as speech production, may be adversely affected by deviations of a structural nature(especially, Class III malocclusion) . Twenty adults with Class III malocclusion(13 female and 7 male) were studied preoperative, immediate postoperative and either 6 or 12 months postoperative lateral cephalograms. They had mandibular prognathism and had undergone mandible setback operation. The position of tongue, soft palate(Uvula), hyoid bone, respiratory track width, and pharyngeal depth were assessed on lateral cephalograms with 23 cephalometric variables, ANOVA, Paired t-tests and Pearson's product-moment correlation coefficient tests were used to evalute the operative changes in all cephalometric parameters. A experienced speech and language pathologists performed narrow phonetic transcriptions of tape-recorded words and sentences produced by each of the ninth patients and the recording tapes were analyzed by phonetic computer program(Computerized Speech Lab(CSL) Model 4300BI(U.S.A.)) These judges also recorded their ratings of each patient's overall consonants, hypernasality, hyponasality, and articulation proficiency. The results obtained are as follows ; 1.There were significant changes in distance of posterior pharyngeal wall to tongue (TI-TW2, TS-TW3) after the surgery at 6 months postoperatively(each p<0.01 p<0.05) 2.The posterior tongue point(TI, TS, PPT) moved posteriorly after surgery and remained to its changed position at 6 months postoperatively(p<0.05) . The displacement of tongue was correlated with the movement of mandibular setback amount(p<0.05). The hyoid bone moved posteriorly superiorly after immediate postoperative period. There was significant changes in hyoid bone movement after immediated post-operative period(p<0.05), but returned to its original position during the follow-up period(p>0.05) 3.The soft palate was displaced posteriorly superiorly after immediated operative period and remained to its changed position at 6 months postoperatively(p<0.05) ANS-PNS-SPT angle increasing, PPU-PPPo distance narrowing was showed after surgery, and remained its appearance 6 months postoperactively (p<0.05) 4.There were significant changes in formant value and squre diagram of vowel sound after the orthognathic surgery and the follow-up period. There were significant changes in /ㅅ/sound and posterior tongue sound. 5.The posterior movement of tongue and the posteriosuperior movement of soft palate was correlated with mandibular setback amount after orthognathic surgery. On the vowel squre diagram, the author found that the place of articulation after operation moved downward, backward, upward. 6.In assessing speech abnormalities, dental occlusion should be considered as a contributing factor. The vast majority of subjects with preoperactive misarticulations eliminated or reduced their errors following orthognathic surgery. There was significant difference in speech impovement between pre- and post-operation.

This experiment was conducted to examine effects of different polyethylene film mulching, pinching methods, and shading level on growth and root yield of Bupleurum falcatum L. Plant height, leaf length, leaf width, stem diameter, root length, number of lateral roots and number of branches were fewer in a polyethylene film mulching than in a non-mulching. In a non-mulching, plant height was highest at a non-pinching and leaf length, leaf width, root length, root diameter, number of lateral roots, number of branches were greatest at the third pinching (25 Aug.) among the pinching treatments. In a polyethylene film mulching, plant height was highest at a non-mulching and leaf length, leaf width, stem diameter, root length, root diameter were greatest at the third pinching (25 Aug.) among the pinching treatments. Characteristics such as fresh aboveground weight, fresh root weight, dry aboveground weight, dry root weight were greatest in a polyethylene film mulching and total yield per 3.3㎡ was greatest in a non-mulching between polyethylene film mulching and non-mulching. Root yield in a non-mulching was two fold greater than in a polyethylene film mulching, and in a non-mulching, was much greater at the third-pinching (25 Aug.) among the pinching treatments. As the shading level was increased from 0 to 90%, plant height was increased from 83.4 to 100.3cm. Stem diameter, root length, and root diameter were decreased with the increased shading level. Fresh aboveground and root weights were decreased as shading level was increased.

Ovarian pregnancy is an uncommon form of the ectopic pregnancies. The ovarian vascularity results in maternal hemorrhage early in the first trimester, which disrupts the pregnancy and usually ruptures the ovary with sufficient hemoperitoneum to require emergency operation. This report presents 10 cases of ovarian pregnancy by retrospective review between January 1986 and December 1995 at the Department of Obstetrics and Gynecology, Soonchunhyang University Hospital. There was 19,849 deliveries and 637 ectopic pregnancies during same period. It showed that the incidence of ovarian pregnancy was 3.21 % of all ectopic pregnancies. The clinical features of ovarian pregnancy revealed that abdominal pain was the major symptom, and history of amenorrhea was obscure. Because of life-threatening course, the early diagnosis and treatment of ovarian pregnancy is important. The clinical diagnosis of ovarian pregnancy was more difficult than that of tubal pregnancy.

要約표고폐골목의 재활용을 목적으로 폐골목과 정상재의 칩을 일정비율로 혼합하여 얻은 목질보드의 성질을 조사, 검토하였다. 그 결과 폐골목의 목섬유는 정상재보다 다소 짧고 표 면이 거칠었으며 폐골목 변재부의 밀도는 정상재에 비해 상당히 낮았다. 파티클보드의 두께 팽윤율 및 파괴계수의 시험결과 폐골목을 25~50% 정도 혼합한 경우는 정상재와 비슷한 값 을 나타냈다.결론적으로 폐골목은 파티클보드의 재료로 사용될 수 있고 정상재와의 혼합비율은 25~50% 범위에서 조정되어야 할 것으로 생각되었다.ABSTRACTTo provide further information for reutilization of the bed-logs decayed by oak mushroomfLentinus edodes), the properties of wood-based board prepared with mixed materials of normal wood and bed-logs were examined.Wood fibers in bed-logs showed different morphology from normal wood fibers, that is, shorter length and rough surface. Thickness swelling increased with increasing mixing ratio of bed-log. On the other hand, modulus of rupture(MOR) in bending strength decreased. In products, the visual surface of board prepared from higher mixing rate of bed-log chips was smooth.Consquently, it is considered that the optimum mixing rate of bed-log to normal wood is the range of 25-50% and the bed-log can be used for raw material of board instead of normal wood.

It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.

Grape vinegar(A) and grape onion vinegar(B) added (3% of onion juice) were produced through two stages of fermentation(alcohol fermentation and acetic acid fermentation) to increase the grape's use. Grape wine which contained 5.6% alcohol was produced on the 3rd day of first stage. Then through the second stages, grape vinegar, of which total acidity was 5.37% was produced. The quality of (A) and (B) which was produced through the two stages of fermentation was compared with the traditional grape vinegar(C,D) in the market. The content of sugar in (D) was a little higher such as 5.4 °Brix than others. That of (A) and (B) was 5.13, 4.98 °Brix respectively. The content of remaining alcohol in (C) was high such as 0.23% comparatively, But there was no remaining alcohol in (A) and (B). The content of acetic acid was 4.3~5.3% as a major organic acid of vinegars. The content of tartaric acid was 340.0 in (A), 316.7 in (B), 322.6 in (C) and 391.7㎎% in (D). The content of lactic acid was distinctly high such as 277.4㎎% in (D). There were differences such as 9.2~15.5㎎% in the content of total free amino acids among grape vinegars. (D) contained 15.5㎎% of total free amino acid and (B) also highly such as 12.0㎎%. Potassium was high in grape vinegars. The content of potassium, sodium and copper was higher in (A) than (B).

Stearic acid was deposited on surface of 9[MHz], AT-cut quartz crystal microbalance as gas sensing material using Langmuir-Blodgett(LB) technique. We measured gas response between deposited LB films and organic gas for special temperature(0, 25, 50, 80℃). The resonant frequency changed due to absorbance of organic gas such as methanol, ethanol, propanol and butanol gas at special temperature. As a result, the resonant frequency responded to organic gas at 0, 25 [℃]. but, the resonant frequency almost not responded to organic gas at 50, 80[℃].
