機能論的 階層理論에 관한 考察

韓相旭 順天大學校 1985 論文集 人文社會科學篇 Vol.4 No.-

The writer of this paper attempts to summarize the functional theory of stratification represented mainly by Davis-Moore theory and to study the basic issues and the adequacy of it. The central argument advanced by Davis and Moore can be stated as follows: 1) Stratification is functionally necessary become every society needs a mechanism inducing people to occupy positions which are socially important and require training;material rewards and prestige act as stimuli towards the occupation of such positions. 2) The existence of the above mechanism ensures that the important positions are conscientiously taken up by the most qualified persons. 3) Therefore, social stratification(uneven distribution of material rewards and of prestige) is both positively functional and inevitable in any society. But those who criticize the basic propositions of the Davis-Moore theory have aptly pointed out and dealt with the theoretically important aspects of the theory which Davis and Moore have failed to take into consideration. The criticism of Davis-Moore theory largely centers on their definition, their argument on the functional necessity of stratification and its inconsistency with social facts. Controversy up to now seems to have effectively sorted out the metaphysical postulate and questionable assumptions from the more valuable ingredients. These ingredients contain considerable insight, but by themselves they do not add up to a fully adequate theory of stratification. The adequacy of the functional theory of stratification should be limited to the range discussed in this paper.

한상익,전양환,이창욱 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.5

연구목적: 저자들은 알코올의존 환자들을 대상으로 뇌파, 청각사건관련전위 P300등 신경생리학적 검사와 신경 인지기능 검사를 실시하여 알코올이 뇌기능에 미치는 영향을 확인하고자 본 연구를 시도하였다. 방법: 알코올의존 환자군 33명과 정상 대조군 67명을 대상으로 하였다. P300의 잠복기를 고전적 방법, Glo-bal Field Power 방법, 그리고 기존의 방법을 변형시킨 수정된 방법 등 세 가지로 결정하였으며 다른 검사값들과의 비교는 Global Field Power방법으로 측정한 결과를 사용하였다. 지능검사는 한국판 웩슬러 지능검사를 사용하였고 웩슬러 기억검사와 Trail Making B검사를 이용하여 신경인지기능을 평가하였다. 뇌파분석은 주파수 영역별로 델타파(δ, 1-3.5Hz), 세타파(θ,4-7.5Hz), 알파파(α,8-13Hz),베타파(β,13.5-18Hz)의 4개 구역으로 나눈 후 상대적 Power로 분석하였다. 결과: P300 은 환자군에서 작고 늦게 나타났으며 측정 방법에 의한 차이도 없었다. 환자군에서 낮은 지능을 보였으나, P300은 지능에 의해 영향을 받지 않았다. 환자군에서 Trail Making B 검사 수행시간이 오래걸렸으나 웩슬러 기억검사에서는 차이가 없었다. 뇌파분석 결과 두 군간의 차이는 없었다. 결론: 알코올의존 환자들은 신경생리학적인 측면에서 뇌기능의 저하를 보이고 있었고 이는 지능에 의해 영향을 받지 않았다. 신경인지기능검사는 이들이 측두엽보다는 전두엽의 기능이 더욱 더 저하하고 있다는 것을 시사하고 있다. 중심단어:알코올 의존·정량적 뇌파·사건관련전위 P300·인지기능. Objective: The purpose of this study is to determine whether patients with alcohol dependence do have brain dysfunction by auditory event related potential P300, EEG, and neuro-cognitive function test or not. Method: Subjects were composed of patients with alcohol dependence(N=33) and normal controls(N=67). P300 was determined by conventional method, Global Field Power method,and modified method. Also Korea Wechsler Intelligence Scale, Wechsler Memory Scale, and Trail Making B were tested. Spectral EEG was analyzed by the ranges of Hz, delta(δ,1-3.5Hz), theta (θ, 4-7.5Hz), alpha(α,8-13Hz), and beta(β,13.5-18Hz), and compared by relative power. Results: In patients with alcohol dependence, P300 was smaller and later, and there was no difference between the measurement methods of P300. Lower IQ score was shown in patients with alcohol dependence, but it did not affect the P300 results. It took more time to perform Trail Making B test in patients with alcohol dependence, but there was no difference between groups in Wechsler Memory Scale. Spectrum EEG was shown as similar patterns. Conclusion: It suggests that patients with alcohol dependence have brain dysfunction in so-me neurophysiological aspects, regrdless of intelligence. And frontal lobe dysfunction might be more severe than temporal one in patients with alcohol dependence. KEY WORDS:Alcohol dependence·EEG·P300·Neurocognitive function.

韓國人價値觀硏究에 있어서 價値觀分類의 適用에 關한 考察

韓相旭 順天大學校 1984 論文集 人文社會科學篇 Vol.3 No.-

We can classify values into two categories;moral values and amoral values. It is essential to apply this classification of values to the study of values because moral values are guite different in many aspects from amoral values. Moral values are different from amoral values in character and in critical condition of internalization, thereore, the teaching method and the scale of moral values should be different form those of amoral values. Lack of this classification of values in the study of values leads ot such serious problems as we have discussed in this paper. In spite of that, the studies of Korean values up to now lack this classification of values. The aim of the study of korean velues is to understand korean volues and to make korean internalize the disrable values for modernization and demorcratization of Korean sosiety. To atlain the aim, we have to develop valid scale of values, explore desirable values and develop effective method of values education based upon this classification of values. In conclusion, the application of the classification of values to the study of korean values is the clue to the attainment of the aim.

In this paper, we proposes two phase chopper system with flour. separate groups of D.C motor for regenerative braking. The main circuit consists of four sets of chopping parts, eight diodes and four separate groups of D.C motor. Although the proposed chopper circuit requires more circuit elements than the conventional two phase chopper system with, combined output, it has the following advantages: (1) The region of regenerative braking becomes twice as that of the conventional two phase chopper system. (2)Current division of load becomes equalized. Therefore. it is possible to drive not only series motor but also shunt and separately excited motor (3) The harmonic component of the source current is greatly diminished.

본 연구에서는 석골재 자원개발에서 널리 사용되고 있는 발파 조건을 고려하여 암반의 변형 및 파괴거동에 대한 특성을 규명하기 위한 컴퓨터 모델링을 시도하였다. 현재까지 이루어진 몇몇 연구들은, 발파에 의한 암반의 거동을 실제 동하중이 적용되고 있는 상태와는 달리 정적 상태 하의 조건에서 주로 이루어져 왔다. 그러나 실제 발파 거동은 동적 거동을보이므로 동역학적 해석을 하지 않을 경우 많은 오차를 포함한 상태하의 개괄적인 특성의 추정에 그칠 수밖에 없는 단점을 지니고 있었다. 본 연구에서는 동하중 하에서의 탄소성 해석을 실시하여 채석시 발파 하중에 대한 암반의 하중 반응, 탄성 및 소성 변형의 발생 특성, 그리고 이로 인한 발파 균열의 성장 전파 특성을 규명함으로써 발파로 인한 균열의 능동적 제어와 보다 효율적인 발파가 이루어 질 수 있는 조건들을 규명하고자 하였다. 해석 결과 일반 발파공의 경우에서 탄성 모델의 경우 공반경의 약 3배인 6cm까지 집중된 응력의 크기가 파괴강도를 초과하는 것으로 나타났으며, 탄소성 모델의 경우 균열의 전파 거리는 공반경의 15배인 30cm까지 균열이 확장되었다. 또한 폭 5mm 길이 20mm의 노치가 가공된 발파공의 경우 공반경의 25배인 50cm까지 균열이 진전되었으며, 균열의 방향은 노치 첨단의 방향으로 생성되는 것을 알 수 있다. 노치의 폭과 길이에 의한 영향은, 폭은 10mm이하일 경우가 적합하다고 판단되며, 길이는 균열의 성장 길이에 비례하는 경향이 있는 것을 알 수 있었다. Conditions for developing an effective controlled blast model were studied using finite element method, analyzing elastic and elasto-plastic case under static and dynamic load for normal blast hole and notched blast hole. Results show that from the elastic analysis of normal blast hole with 2 cm radius, stress concentrated by blasting exceeds tensile strength for the region up to 6 cm from hole wall and in case of elasto-plastic analysis, it was expanded up to 30 cm. For the notched blast hole with its width of 5mm and length 20mm, crack due to blasting was propagated up to 50 cm.

Papillary eccrine adenoma is a rare benign sweat gland neoplasm. It occurs most often as a solitary nodule in women and is located predominantly on the distal portion of the extremities. This tumor is similar to tubular apocrine adenoma in histological and clinical aspects, so distinction of these tumors is still controversial. We report a case of two papillary eccrine adenomas developed on the left popliteal and calf area of a 58-year-old-man, this is the first report of the multiple papillary eccrine adenomas in Korea.

The peak wavelength and temperatures of W-Halogen standard light source were measured by using the modified Wien's Law. In the case of graybody, the emissivity ε should be taken into account in using the Wien's Law. In the experiment, PDA spectroscope was used for the measurement of peak wavelength of intensity distribution of spectrum. As the current of light source increases from 5A to 7.4A, the peak wavelength of intensity distribution of the spectrum decreased from 717nm to 690nm, and temperature increased from 3127K to 3330K. Illuminations of three-wavelength lamps and light source were also measured. It was found that irradiation spectrum of those three-wavelength lamps are not coincident to blue(450nm), green(550nm) and red(610nm).

The method of manipulation by striking a part and letting it slide until it comes to rest, has been very little studied. However, the manipulation method is not uncommon in our daily lives. We analyze the dynamic behavior of a rigid polygonal part being striked and sliding on a horizontal surface under the action of friction. There are two parts to this problem; one is the impact problem, and the other is the sliding problem. We characterize the impact and sliding dynamics with friction for polygonal parts, and present the possibility of reverse calculation for motion planning of striking operations. Using a high speed video camera. the computer simulation results are experimentally verified. Simulation and experimental results agree well.

석회암을 이용한 골재의 알칼리 반응성을 측정하기 위하여 한국공업규격의 표준시험 방법에 의한 팽창성을 측정하였다. 기존의 연구결과에 의하면 특히 백운석을 포함하는 석회암의 경우 골재-알칼리 반응이 상당한 것으로 알려지고 있으나, 본 연구에 사용된 석회암 시료의 경우는 알칼리 반응성이 매우 작은 것으로 나타났다. 또한, 역학적 특성의 결과도 매우 양호하며 골재로서의 활용성이 충분한 것으로 판단된다. An experimental program was undertaken to investigate the alkali-aggregate reaction of limestone aggregates, following the standard testing method for potential alkali reactivity of carbonate rocks for concrete aggregates. It is generally known tat dolomitic limestones may exhibit high potential of alkali-aggregate reaction. However, the limestone samples employed in this study showed negligible effect of the alkali reaction, even with substantial dolomite content. It is also concluded that the mechanical properties of the limestone aggregates are adaptable for concrete aggregates
