Objective & Methods : In the point of several medical books included 'Internal Classic' and Hyungsang medicine, the writer studied about meridian theory and it's disorders, after adapting to acupuncture and herb medicine. Results : 1. Dr. Jisan explained concretely physiological and pathological meridian appearances with using metaphor about phenomenons of nature and human living. 2. Shapes corresponding to meridian are considered as Yukkyunghyung formed by more or less of vigor and blood, and by tendency of up and down in eyes and nose, and also contained diseases of viscera and characters. 3. The colors connected with meridian are changed according to conditions, and meridian is seen through colors. And then colors is the properties of vital energy and symbol of spirit, that is expressed as aspect of essence, vigor, spirit and blood, as the original color of five viscera, as the colors of four seasons and as the colors of diseases. So the changes of feelings are appeared to meridian flow. 4. The method of examining pulse for meridian disorders is applied to Jisan diagram. Jisan diagram is devised from mutual communication of viscera and connection with inside and outside. It is conjugated widely in clinical examination to be distinguished into Dam-Bangkwang, into diseased part of viscera and into meridian. Also it is conjugated recuperation of diseases. 5. The meridian diseases are appeared all the distributed parts of meridian, especially skin, hair, eyebrow, and the ends of the extremities which are sensitive to stimulus. The causes are the disharmony between vital energy and blood and the discordance of six atmospheric variation. The symptoms are skinny aches, itching and eruption, etc. Conclusions : The acupuncture of Hyungsang medicine which utilizes classification of shapes, examining pulse according to Jisan diagram and demonstration of symptoms, is very effective and required systematical study from now on.

The aim of this study is to investigate facial temperature changes induced by facial expression and emotional state in order to recognize a persons emotion using facial thermal images. Background: Facial thermal images have two advantages compared to visual images. Firstly, facial temperature measured by thermal camera does not depend on skin color, darkness, and lighting condition. Secondly, facial thermal images are changed not only by facial expression but also emotional state. To our knowledge, there is no study to concurrently investigate these two sources of facial temperature changes. Method: 231 students participated in the experiment. Four kinds of stimuli inducing anger, fear, boredom, and neutral were presented to participants and the facial temperatures were measured by an infrared camera. Each stimulus consisted of baseline and emotion period. Baseline period lasted during 1min and emotion period 1~3min. In the data analysis, the temperature differences between the baseline and emotion state were analyzed. Eyes, mouth, and glabella were selected for facial expression features, and forehead, nose, cheeks were selected for emotional state features. Results: The temperatures of eyes, mouth, glanella, forehead, and nose area were significantly decreased during the emotional experience and the changes were significantly different by the kind of emotion. The result of linear discriminant analysis for emotion recognition showed that the correct classification percentage in four emotions was 62.7% when using both facial expression features and emotional state features. The accuracy was slightly but significantly decreased at 56.7% when using only facial expression features, and the accuracy was 40.2% when using only emotional state features. Conclusion: Facial expression features are essential in emotion recognition, but emotion state features are also important to classify the emotion. Application: The results of this study can be applied to human-computer interaction system in the work places or the automobiles.

One hundred and seventy two patients of primary lung cancer, confirmed by tissue diagnosis at the Dept. of Thoracic and Cardiovascular Surgery in Korea University Hospital between June 1973 and August 1988, were evaluated and restaged with New International TNM classification, and the actuarial survival rate was obtained using Kaplan-Meier equation. The results of analysis were as follows. 1. Male to female ratio was 3.8:1, and prevalent age groups were sixth and seventh decades [76.4 %]. 2. The most common subjective symptom was cough [55.2 %], and 67.4 % of all patients were visited to hospital less than 6 months of symptoms. 3. Positive rates for tissue diagnosis were 100% in open chest or metastatic lymph node biopsy, 80 % in mediastinoscopic biopsy, 60 % in pleural biopsy, 59 % in pleural fluid cytology, 36% in bronchoscopic biopsy, and 22 % in sputum cytology. 4. The order of frequency of cell type was squamous cell carcinoma [53.0%], adenocarcinoma [22.0 %], small cell carcinoma [14.5 %], and so on. 5. Operability and resectability were 44% and 62% respectively, but they were improved recently. 6. Open and closure was done in 44 % of operated patients, uni or bilobectomy in 38 % and pneumonectomy in 24 %. 7. Overall operative mortality rate was 2.6 %. 8. The order of frequency of stage level was S3b [42.0 %], S3a [25.1 %], S1 [15.6%], and so on. 9. Distant metastasis, i.e. stage 4, was noted in 9.5 % of cases, and the sites of frequency were bone, brain, skin, and so on. 10. Actuarial survival rate was 1 year 48.2%, 2 year 36.9%, 3 year 31.2%, and 5 year 20.8%. According to above listed factors, 5 year survival rate was highest in squamous cell carcinoma, lobectomized cases, stage 1, NO in TNM system, and resectable cases. But T factor in TNM system and radiation therapy in nonresectable cases did not show statistical significance in life expectancy.

We examined the cause of albinism in a hatchery population of flounder in terms of environmental and nutritional factors, including the effects of light intensity (130-12,300 lux), photoperiod (12L/12D or 24L/0D), tank substrate (concrete or fiber-reinforced polymer), tank color (white or dark green) and supplement with enriched live food, and also compared the growth of normal and albino fry under both 12L/12D and 24L/0D. Further to, normalization of the skin pigmentation pattern on the ocular side has been juvestigated after rearing the albino fry for 2 years after their identification and classification and found that, light intensity did not play a critical role in the development of normal pigmentation or albinism in the flounder. By contrast, the photoperiod was a weak inducer of albinism in the flounder. Tank substrate and color also affected the hypomelanosis on the ocular side of the flounder fry. The choice and supplementation of enriched live foods could drastically reduce the incidence of albinos in hatcheries. On comparing the growth of normal and albino fry, while there was no difference between the groups under 24L/0D, the growth of the albino flounder was slower under 12L/12D. Although coloration resulting from xanthophore and melanophore, but not iridophores, occurred on the ocular side, evidence of albinism remained on the ocular side of flounders.
