In patients with unilateral condylar hyperplasia, increased length of the condylar neck causes deviation of the mandible to the opposite site, resulting in facial asymmetry, but the arch form and general contour of the displaced mandible is approximately symmetric. So, the unilateral condylectomy have been prefered surgical method among the surgeons. The purpose of this study is to analyze the postoperative results comparatively following two different surgical methods, condylectomy and ramus surgery, in unilateral condylar hyperplasia. Case of 6 patients with the unilateral condylar hyerplasia were analyzed in this study, 3 case of the condylectomy only, 3 cases of the ramus surgery, Clinical and radiographic evaluations were tried for comparison. In conclusion, comparative results between two groups did not show any significant difference,but we confirmed that unilateral condylectomy could be a excellent surgical methods in unilateral condylar hyperplasia thinking over the unique morphological characteristics of it.

In textured material, diffraction angle 2θ usually shows a nonlinear relation against sin^2Ψ due to elastic anisotropy of crystals. SPHD and SPCD steel is cold-rolled carbon steel for automobile. The characteristics X-ray for stress measurement is Cr K_α and Mo K_α1characteristic X-ray. The sin^2Ψ-2θ diagram under elastic strain seems to have a linear behavior using regression line of data but has a nonlinear behavior in distribution of data by Cr K_αcharacteristic X-ray. As the plastic strain of specimen increases, the nonlinearity of 2θ with respect to sin^2Ψ increases remarkably. On the other hand, the diffraction angle 2 θ by Mo K_α1 characteristic X-ray shows a good linearity on sin^2Ψ-2θ diagram under plastic strain as well as elastic strain. Therefore, This paper presents the measurement of residual stress in cold-rolled carbon steel for automobile using penetration depth of Mo K_α1 charateristic X-ray and multiplicity factor of crystal diffraction plane.

본 연구에서는 부력저항용 영구앵커의 거동을 시공단계별로 구분하여 분석한다. 즉, 앵커의 두부에 하중계를 설치하여 앵커축력을 계측하였으며, 이 계측결과를 토대로, 앵커축력의 손실, 건물자중의 증가 및 외적조건 변화에 따른 앵커의 거동을 분석하였다. 영구앵커는 초기인장력에 비하여 Jacking Free시 인장력이 약 7% 정도 감소하며, 최종인장력은 약 15%정도 감소한다. 한편, 앵커의 초기인장력은 외력이 작용하지 않아도 PC 강선의 relaxation, 주입재 및 지반의 creep 등의 내적요인에 의하여 비선형적으로 감소되어 1차 수렴치에 도달하게 된다. 1차 흙되메우기 작업 기간동안 앵커축력은 흙되메우기에 따른 횡방향 토압이 증가 및 상부구조물의 자중증가로 인하여 감소된다. 그러나, 흙되메우기 작업이 중단된 기간동안 되메우기한 흙의 이완현상으로 횡방향 토압이 감소되며 이로 인하여 앵커축력이 증가하게 된다. 그리고, 되메우기한 흙속으로 지하수가 유입되어 부력이 증가하게 되므로 앵커축력은 증가하게 된다. 이때 앵커축력은 1차 수렴치까지 회복하게 된다. The behavior of permanent anchors for buoyant resistance is investigated at each construction stage. The prestressed anchor forces were measured by load cells which were attached to anchor head. On the basis of instrumentation, the loss of anchor force and the behavior of anchor by increment of structure weight and change of external condition were investigated. Prestressed anchor force at jacking free is decreased by about 7% than initial prestressed anchor force and decreased by about 15% finally. Although external forces does not act on the substructure, initial anchor force is decreased nonlinearly due to relaxation of PC strand and creep of grouting materials and soils. Also, anchor force was converged at the first convergent value. When first backfill was performed, anchor force was decreased due to increment of lateral earth pressure and superstructure weight. But, anchor force grew gradually during the period of breaking backfill by lowering of lateral earth pressure due to relaxation of soils. When groundwater inflowed into backfill soils, anchor force is slowly increased by uplift force below mat foundation. At that time, anchor force is recovered by the first convergent value.

Korean psychiatrists are more apt to take the abnormal drinking behavior lightly and regard the psychosomatic symptoms as more serious, comparing with American psychiatrists. On the other hand, physicians as well as adults from the population in Korea are less concerned about the neurotic and psychosomatic symptoms and alcoholic behavior as psychiatric problems. It is the authors' concern to understand such differences in opinion about abnormal behaviors from the cultural and social psychiatric view point. The authors used Dohrenwend's questionaire form of 45 mental symptoms and three additional items i. e., homosexual behavior, symptom of senile psychosis and delusion of jealousy following the authors' interests. Each item was rated by three point cale (psychiatrically very serious=2 points, somewhat serious=1, not serious at all=0) and evaluated with critical ratio. As a preliminary study, the reliability of this questionaire was confirmed by the test-retest method; Spearman's rho was 0,93. The subjects in this study consist of 50 psychiatrists, 49 physicians, 54 herb practitioners and 154 adults from the normal population(60 urban samples and 94 rural samples). The collection was carried out by individual interviews for the physicians and normal samples, by letters for the psychiatrists and the herb practitioners. And the data of American psychiatrists compared in this study were quoted from Dohrenwend's report(27). This study has two parts: one is the cross-cultural comparison between American psychiatrists and Korean ones, the other is intracultural comparison among psychiatrists, physicians, herb practitioners and normal population samples. Inspite of the general notion that Korean psychiatry has been much oriented to American psychiatry for over twenty years, there are definite differences in opinion about the severity of abnormal behaviors between American and Korean psychiatrist, especially about alcoholic behavior and psychosomatic symptoms. Such differences are possibly interpreted as arising from the cultural differences. The American psychiatrists seem to be more concerned about alcoholic behavior probably due to the strict attitude of people and/or the fact that the United States reveals the highest incidence of alcoholism throughout the world. The Korea psychiatrists, however, have much tolerable attitude toward alcoholic behavior according to the cultural tradition. Solitary drinking is hardly found in Korea; drinking in Korea is a suitable way of interpersonal contact. They drink slowly and are not so intensively dependent upon alcohol itself. Dependency need to alcohol can be diffused to the other persons. And they take alcohol with many kinds of side-dishes. These drinking manners seem to be cultural virtues for low incidence of alcoholism in Korea. Thus, Korean psychiatrists as well as adults from normal population have highly tolerable attitude toward alcoholic behavior. Even when some person reveals a destructive behavior after drinking, they grant it as a personal charm. Korea psychiatrists, therefore, are not so nervous about the alcoholic behavior. On the other hard, the psychosomatic problems seem to be serious in Korean mental patients. They are easily apt to express their emotional problems as somatic symptoms possibly due to the disease concept of oriental herb medicine that has a high tendency of projection of emotional conflicts unto the soma. So most of Korean people are not aware that psychosomatic symptoms are originated from the emotional problems, and quite contrary to it, the psychiatrists may be highly conscious of psychosomatic symptoms. Another significant difference is seen in suicidal idea and suspiciousness: American psychiatrists regard them as more serious, and reversely Korean psychiatrists regard them as less serious. Such a pattern may also be derived from the socio-cultural differences. When Koreans are either dissapointed or delighted, they say frequently "I want to die" or "It's funny to death" and so on. This idiomatic expression is far from the real death wish but rather an expression of magnification. And the suicidal idea itself is frequently seen in normal population even suicidal attempt is evaluated as abnormal in Korea. With such reasons, Korean psychiatrists may notice suicidal idea as less serious than American psychiatrists. And the suspiciousness may be a way of living for the people under the historical turmoil and vigorous aculturation, that it is perceived as not so abnormal. The next problem is the marked discrepancy of opinion about abnormal behaviors among psychiatrists, physicians, herb practitioners and normal population samples. The agreement of physicians, herb practitioners, urban samples and rural samples with the psychiatrists on the relative severity of symptoms revealed as Spearman's rho of 0.79, 0.59, 0.58 and 0.44 respectively. It is the main point of problem that physicians are less aware of neurotic symptoms which can appear in the somatic illness, and of psychosomatic symptoms as psychiatric problem. Possible reason is that Korean physician have been oriented to the somatic medicine without proper psychosomatic orientation. On the other hand, the herb practitioners are apt to ignore the severity of psychotic symptoms and on the other, regard the neurotic and psychosomatic symptoms as much as psychiatrists' opinion. And the samples of normal population regard the neurotic symptoms as more serious than the psychotic symptoms, and are not aware of the psychosomatic symptoms as psychiatric problems. Physicians, herb practitioners and samples from the normal population underestimate the alcoholic behavior more than psychiatrists do. The alcoholism according to physicians' opinion is rather somatic problem than psychological one. The herb practitioners and adults from normal population manifest the prominently tolerable attitude toward alcoholic behavior. In conclusion, two kinds of problems can be suggested. One is that the difference between Korean and American psychiatrists in the evaluation on the severity of abnormal behaviors, is possibly due to sociocultural differences. The other is the intracultural difference among psychiatrists, physicians, herb practitioners and adults from normal population. Such a difference suggests that there is a considerable cultural lag in the disease concept and attitude between the modern psychiatry and the cultural tradition. This discrepancy can result in the undesirable wandering of patients for seeking the treatment and some hardship in modern psychiatric practitioning in Korea.

This study was done to evaluate the correlations between the size, the form of the cranial base, head posture and the horizontal and vertical position of craniofacial structures. For this purpose, 100 cephalometric radiograhs were taken from the sample composed of 51 male and 49 female, 12 measurement criteria and 37 reference points were established and digitized, then calculation was performed for the values of measurement variables and the horizontal and vertical position of reference points. The correlations between them were analyzed statistically and mean facial diagrams were constructed and compared with the selected groups which were composed of 10 Sample each as large and small group from the measurement value. The following results were obtained: 1. The angles n-s-ba and n-s-ar as variables for the form of cranial base correlated highly to the horizontal and vertical position of reference points in the cervical column with statistical significance(0.1% level). 2. The angles n-s-ba and n-s-ar as variables for the form of cranial base correlated to the horizontal position of the reference points in the facial structure with statistical significance(1% level), but not to the vertical position of them(5% level) 3. The length n-s, n-ba and n-ar as variables for the size of cranial base were correlated th the position of craniofacial structures in various ways, but in general, highly correlated to the horizontal and vertical position of midfacial structures around the teeth and alveolar area. 4. the angle NSL/CVT and NSL/OPT as postural variables for the inclination of cranial base and cervical column were correlated to the horizontal position of the craniofacial structures with statistical significance(1% level), but not to the vertical position of them(5% level). 5. The angle OPT/HOR and CVT/HOR as postural variables for the inclination of cranial base and ture horizontal line were not correlated to the horizontal and vertical position of the craniofacial structures with statistical significance(5% level) 6. The correlation between the measurement variables and horizontal and vertical positions of the reference points in soft tissue were shown as similar to the related hard tissue points.

This study is designed to grasp the elements and situations of stage fright in order to propose a part of ways to cope with it. We make 511 top-class high school players, male and female, in the central districts (Seoul, Inchon, Kyungki, Chungbuk, and Kangweon Province) on object of questionnaire, and get the following results. Through players generally have all-round characters they show weakness in the superiority and emotional stability while showing strength in the sonformity. This fact comes to be related to the elements which cause stage fright. Physiological changes also have many effects on the symptom of stage fright. Especially, stage fright increases when players show sensitive reaction to the self-consciousness of final consequence which comes from the tension or uneasiness of sympathetic nerve, Thus, it turns out that players make use of reducing psychological burden by physical exercise or adjusting the level of demanded result in order to release the stage fright.

文化變遷에 따른 精神疾患 槪念 및 治療法에 관한 見解調査

Opinion about the cause and desirable way of treatment of mental illnesses, psychoses and epilepsy, were collected from 379 rural peoples and 201 peoples in Seoul city by individual informal interviews. Purposefully, the interview were limited to old people over 50 year of age who were resident in the rural areas with traditional way of life, and to the relatively civilized peoples who had been resident in Seoul for the past ten years. The results from the two sources were compared and discussed from the point view of acculturation. It was obvious that the concepts in cause and treatment of mental illnesses was shifted from the primitive orientation to the modern one. Shamanistic and primitive medicinal concepts were almost neglected in Seoul sample, whereas the two concepts were definetely high as 53.2% for psychoses, 88.3% for epilepsy in rural sample. Seoul sample unexpectedly revealed high psychological orientation to the causs of psychoses and even to the cause of epilepsy as 88.5% and 17.6% each. On the other, rural sample manifested the psychological orientation to the cause psychoses and epilepsy as 46.8% and 3.4% respectively. Way of treatment was also evidently changed; supernatural and primitive medicinal treatments for the mental illnesses were scarcely adviced by Seoul people, whereas the two treatments were adviced by the rural people in 44.5% and 18.6% each for the psychoses, and 4.4% and 63.4% for the epilepsy. Folkpsychological way of treatment for the psychoses was 61.7% in Seoul, 20.0% in the rural area. Even for the epilepsy, this psychological treatment was 22.2% in Seoul, 2.5% in rural area. Opinion about the efficacy of modern medicine in the treatment of mental illnesses was still negative. Favorable result of modern medical approach for the psychoses could be expected only in 28.6% of Seoul sample, 8.9% of rural sample. That of modern medical approach for the epilepsy could be only in 36.4% of Seoul sample and 10.5% of rural sample. Seoul sample responded to the psychoses as "curable" in 59.3%, but rural sample did in 20.2%. For the prognosis of epilepsy, Seoul sample responded as "curable" in 27.4% and rural sample only in 3.0%. It was impressed that the concept and way of treatment of mental illnesses were apparently changing from the primitive to the civilized by acculturation process. Two kinds of problem would be suggested. One is a discrepancy between concept and real attitude. Seoul people are interestingly enough to have desirable conceptual change of mental illnesses, while they frequently practice shamanistic and primitive medicinal approaches. By such reason, it would be likely that the conceptual acculturation would be the initial step to change, and attitudinal acculturation would be clearly later. The attitudinal acculturation is still intermingled with primitive and modern approaches. Another problem is poor expectation to modern medicine in the treatment of mental illnesses. Prognositc view is also not so favorable as expected, even the Seoul sample is more favorable than the rural is. Furthermore, they, both Seoul and rural peoples, have various kinds of psychological or folkpsychological causes and treatment. This tendency is more prevalent in Seoul. These patterns easily suggest a difficulty of secondary prevention in Korea.
