Although noise-induced hearing loss (NIHL) is the most prevalent occupational disease in Korea, only 10% of the diagnosed cases are compensated. Old (1989-94) and current diagnostic criteria, criteria for workers' compensation of NIHL in Korea, compensation formulas of American Medical Association/American association of Ophthalmology and Otolaryngology (AMA/AAOO), the Committee on Hearing, Bio-Acoustics, Biomechanics (CHABA), American Academy of Otolaryngology (AAO) recommendation were compared. Each criterion was applied on the audiomety data of 4044 workers (8023 ears), who had received the second line screening test of Special Periodic Health Examination Program for noise-exposed workers during 1991-2. First, the resulting proportions of NIHL cases by employing each criterion were compared and strength of agreement was measured using kappa value. Temporary Threshold Shift (TTS) was corrected by noise free interval, and the reduction ratio of NIHL cases was calculated. Theoretical progression model of NIHL was reconstructed from previous studies on the natural course of NIHL to evaluate the change of diagnosis result of each criterion in the model. The kappa value between old and current criteria was 0.19, 0.55 for current criteria and workers' com. criteria, ranging from 0.08 to 0.78, highest coincidence was observed between current criteria and CHABA formula. The current criteria produce most similar results with CHABA formula. If TTS is corrected for NFI, there is about 14% reduction of NIHL cases. The results of applying on NIHL progression model divided the formulas roughly into 3 groups, of which compensation criteria was the most, old criteria and AAO the least conservative. In conclusion, the result of 4 ㎑ audiometry should be excluded in evaluation of hearing level and a new hearing conservation program should be set out. Current diagnostic criteria has an ambiguity in that managerial concept for prevention and purpose of compensation is mixed up. The current diagnostic criteria and compensation criteria could be incorporated into a new formula which is based on the state of the art test for estimating everyday hearing disability.

As use of the visual display terminal(VDT) is becoming more generalized as a result of office automation, the so-called 'VDT syndrome' which is often observed with the workers using VDT has emerged as a serious occupational health problem. However, few comparative study with control group using not only subjective symptom but also physical examination has been conducted. We have conducted a study comparing prevalence rated of musculoskeletal disorder between 113 VDT operators of a telecommunication company and the control groups of housewives and office ladies through a review of subjective symptoms as well as physical examination by physiatrist to understand the magnitude of problem and relative risk of VDT worker. The symptom rates of upper extremity disability in VDT operators were higher than those of controls especially in neck and shoulder area. Fifty-four(47.8%) of 113 VDT operators met our case definition of upper extremity disorder by subjective symptom and physical examination. Myofascial pain syndrome of neck and shoulder muscles were the most common(46.9%). The odd ratio of using VDT operation for developing myofascial pain syndrome in the neck or shoulder area were 2.52(compared to controls of office ladies) and 2.64(compared to controls of housewives). Other anatomical lesion such as elbow, hand and wrist shows slight higher prevalence rates of musculoskeletal disorder than control groups but not statistically significant.

권수한,최희선 慶尙大學校 기초과학연구소 1985 基礎科學硏究所報 Vol.1 No.-

In the atomic absorption spectrometry of chromium by using air-acetylene flame, the interference of various interfering cations on the chromium absorption and repression of this interference by the addition of cerium and yttrium have been investigated. The following conclusions are obtained from the experimental results. 1. The sensitivity for chromium absorbance is favorable when the flow rate ratio of oxygen to acetylene is about 1:1 and the optical axis is 6㎜ above the burner. 2. The interferences by interfering cations existed in the sample solution as the same amount as chromium are completely released by the addition of cerium twice and yttrium three-fold as much as interfering cations.

小豆 成分育種올 위해 主要化學成分의 遺傳關係를 早期에 推定하고 앞으로의 育種計劃에 대한 基礎資料를 얻고자, F_l, F_2 兩世代의 優性程度 및 遺傳子 分布狀態, 그리고 遺傳力과 相關係數等을 推定한 바, 그 結果는 다음과 같다. 1. 優性程度는 全成分에서 各各 超優性으로 遺傳되었으나 Mg는 不完全優性(F_l世代)과 超優性(F_2世代)으로 世代間에 差異가 있었고, F_l 世代의 粗脂肪, 灰分및 Mg와, F_2 世代의 灰分에서는 非對立遺傳子의 關與가 多少 있었다. 2. 各 成分의 遺傳力은 兩世代間에 비교적 낮았으나 K와 粗脂肪은 他成分보다 높았다. 3. 形質相互間의 相關關係에서 灰水化物은 他成分間과 負의 相關을 보였고, 기타 成分들은 相互 正의 相關이었는데, 蛋白質과 粗脂肪은 F_2世代에서 有意한 正의 相關을 나타내었다. A set of 36 crosses of F/s and F_2's from 9 X9 diallel crosses of nine azdukibean varieties were analyzed for estimating genetic parameters, such as gene action, degree of dominance and genotypic correlation. Seven chemical com positions, i. e., carbohydrate, protein, crude fat, ash, K, Ca and Mg were observed. The results obtained are summarized as follows: 1. In Vr-Wr graphical analyses, all chemical compositions except Mg in F/s were found to be inherited in over dominance. 2. The highest heritability value was found in K in both F/s and F/s, but the value of ash was the lowest. 3. The genotypic correlations between carbohydrate and other chemical compositions were negatively correlated, but that between protein and crude fat was positively correlated in F_2's.

It is known that there appear some nonspecific and delicate changes in neuropsychiatric aspect on the workers when they are exposed for a long period to low concentrated organic solvents in the work places. Therefore, it gives rise to the necessity of developing a program for the health supervisor stationed in the work place to supervise these neurobehavioral health affection. In addition to the questionnaire posed to the workers exposed to organic solvents, the study team conducted NCTB(Neurobehavioral Core Test Battery) respectively on an exposed group and a non-exposed group to organic solvents. The study team compared the results and decided whether or not to apply the results to the evaluation program of health affection. The study team divided 132 workers in 6 car repairing factories and 2 textile printing factories into exposed group and non-exposed group, pairing them off into 66 research objects according to their age, sex, and job. Neurobehavioral test was conducted on 6 items, except the POMS test, of NCTB developed by the World Health Organization(WHO). The study team conducted examinations of working environment on the exposed and non-exposed groups of each work place. The analysis of the collected materials for examinations were conducted with GC-MS. The concentration of the mixture in the air, relative to their respective threshold limit values(TLV) was calculated according to the formula of the ACGIH and the Korean threshold limits. The results indicated that for two of eight factories samples the recommended concentration limits for mixtures was exceeded. Of the six tests, the 'digit span forward', 'digit span backward' and 'digit symbol' produced conspicuous statistical differences between the two groups(p<0.1) as a result of compairing the test values by means of paired t-test. The results of respective analysis of the car repairing factories and textile printing factories revealed that the textile printing factories had greater differences between the exposed and the non-exposed than in the car repairing factories. It is presumably because the textile printing workers are continuously exposed to the organic solvents during working hours, whereas the car repairing workers are exposed only when they are doing painting works, The NCTB is assessed very useful in examining the neurobehavioral health affection under the exposure to organic solvents, and, therefore, the study team expects that the NCTB will play an important part in the course of developing a health program for the workers exposed to organic solvents.

In order to obtain some fundamental information for increasing the breeding efficiency of the consistantly high yielding adzuki bean varieties, four seeding dates were treated in two crop years, 1974 and 1975, with 27 cultivars, And the varietal response to the different seeding dates, heritabilities of some quantitative characters, genotypic and phenotypic correlation coefficients among observed characters, and path coefficients were estimated. The results are summarized as follows: 1. Time characters, such as days to flowering, days from flowering to maturity, days to maturity, showed highly stable response to the different seeding dates, and stem diameter and 100-grain weight showed comparatively stable responses to the crop years and seeding dates. 2. The heritability of 100-grain weight showed the highest, and days to flowering, days from flowering to maturity, days to maturity showed less variable heritabilities in the differences of both crop years and seeding dates. 3. Grain yield and stem diameter showed more variable heritabilities in the different crop yeares and the quite different seasonal effects of these two characters were also observed. 4. In gerneral, the genotypic correlation coefficients of the observed characters were higher than the phenotypic correlation coefficient, and consistantly higher and stable correlation coefficients were found between days to flowering and days from flowering to maturity, days to flowering and total plant weight, days to flowering and 100-grain weight, days from flowering to maturity and 100-grain weight and t otal plant weight and 100-grain weight.

The two sets of diallel crosses (5×5 and 9×9 crosses) from nine adzukibean varieties (Yeongdong Jeogdu, Gongju Baegdu, Gyeonggi Gaeguri, Wase Dairuyu No. 1, Natsu Adzuki, Maruba No. 1, Jeogdu, Nesumi Mochi and Hongcheon Jeogdu) were grown in the field for estimating genetic parameters, such as gene action and combining ability in two different generations, F_1 and F_2. From a series of experiments conducted in 1976 to 1977, 1981 to 1982, and two agronomic characters, i.e., days to flowering and 100-grain weight were observed. The results obtained are summarized as follows: 1, In finks and Hayman's (Vr-Wr) graphic analyses, days to flowering and 100-grain weight of F_1's and F_2's from 5×5 and 9×9 crosses were found to be inherited in partial dominance. 2. Mean squares of GCA and SCA were significantly different among two characters in all generations of different crosses, and those of GCA were higher than SCA. 3. The highest GCA effects for days to flowering were expressed Jeogdu in 5×5 cross, Hongcheon Jeogdu in 9×9 cross, ana Jeogdu for 100-grain weight showed relatively high effects in two generations of 5×5 and 9×9 crosses. 4. SCA effects were different among Parents and characters in the different crosses, but the higher SCA effects were exhibited in the hybrid between Yeongdong Jeogdu and Nesumi Mochi in two generations of 5×5 cross.
