A 63-year-old male who had subtotal gastrectomy for early gastric cancer three months ago underwent Tc-99m bone scintigraphy for the evaluation of skeletal metastases. He had no symptoms such as fever, tenderness, or wound discharge. On physical examination, the surgical scat along the midline of the upper abdomen had keloid formation and there was no radiographic evidence of calcification. Bone scintigraphy (Fig. 1A & 1B) demonstrated all unusual linear increased uptake along the midline of the upper abdomen that corresponded to the,skin incision for subtotal gastrectomy. Usually, an incisional scar will not be visualized in Tc-99m methylene diphosphate (MDP) scintigraphy beyond two weeks after surgery.$^{1)}$ Upon reviewing the literature, there were only a few reports where localization of Tc-99m MDP in surgical scars were found two months after surgery.$^{2)}$ It was also reported that a few cases with Tc-99m MDP uptake in the keloid scar developed after surgery. Although there are several potential mechanisms that may explain the uptake of Tc-99m MDP in scar tissue, the primary mechanism in older scars is suggested to be a result of pathological calcification.$^{2)}$ Siddiqui et al$^{3)}$ suggested it could be due to microscopic calcification in small resolving hematomas. However, the primary mechanism in keloid scar is not well-known. We should obtain oblique or lateral views to differentiate the uptake in healing surgical scars from the artifactual uptake.

Objectives The purpose of this study was to find correlations between gastrointestinal disorders, pain, sleep disorder, fatigue, and to figure out characteristics of fatigue in Sasang Constitution using medical devices data. Methods Sixty three subjects were divided into fatigue group and non-fatigue group, both groups had to undergo blood tests, questionnaire, Sasang constitutional analysis tool (SCAT), pulse wave analyzer examination, heart rate variability examination, nail fold capillary microscopic examination. Results 1) The results of questionnaire about fatigue, gastrointestinal disorder, pain, sleep disorder, quality of life had significant differences between fatigue and non-fatigue groups. 2) Soeumin had more serious gastrointestinal problem and Soyangin had more serious sleep disorder in fatigue groups than non-fatigue groups. 3) According to blood test results, there was no difference between fatigue and non-fatigue groups. 4) Elastic parameter of pulse wave analyzer and nail fold capillary microscopic examination showed significant differences between fatigue and non-fatigue groups in Soyangin. Conclusions We reach the conclusion that fatigue is usually accompanied by gastrointestinal disorder, pain, sleep disorder, deterioration in the quality of life. In Soeumin, treating gastrointestinal disorders can be helpful for treatment of fatigue. In Soyangin, improving sleep disorder may be more effective way to treat fatigue.

Korea Meteorological Administration(KMA) has issued the tropical storm(typhoon) warning or advisories when it was developed to tropical storm from tropical depression and a typhoon is expected to influence the Korean peninsula and adjacent seas. Typhoon information includes current typhoon position and intensity. KMA has used the Dvorak Technique to analyze the center of typhoon and it's intensity by using available geostationary satellites' images such as GMS, GOES-9 and MTSAT-1R since 2001. The Dvorak technique is so subjective that the analysis results could be variable according to analysts. To reduce the subjective errors, QuikSCAT seawind data have been used with various analysis data including sea surface temperature from geostationary meteorological satellites, polar orbit satellites, and other observation data. On the other hand, there is an advantage of using the Subjective Dvorak Technique(SDT). SDT can get information about intensity and center of typhoon by using only infrared images of geostationary meteorology satellites. However, there has been a limitation to use the SDT on operational purpose because of lack of observation and information from polar orbit satellites such as SSM/I. Therefore, KMA has established Advanced Objective Dvorak Technique(AODT) system developed by UW/CIMSS(University of Wisconsin-Madison/Cooperative Institude for Meteorological Satellite Studies) to improve current typhoon analysis technique, and the performance has been tested since 2005. We have developed statistical relationships to correct AODT CI numbers according to the SDT CI numbers that have been presumed as truths of typhoons occurred in northwestern pacific ocean by using linear, nonlinear regressions, and neural network principal component analysis. In conclusion, the neural network nonlinear principal component analysis has fitted best to the SDT, and shown Root Mean Square Error(RMSE) 0.42 and coefficient of determination($R^2$) 0.91 by using MTSAT-1R satellite images of 2005. KMA has operated typhoon intensity analysis using SDT and AODT since 2006 and keep trying to correct CI numbers.

Objectives: The purpose of this study is to investigate the emotional characteristics of the Sasang constitution with the Core Seven Emotions Inventory (CSEI) and Temperament and Character Inventory (TCI). Methods: A total of 224 participants were assessed with a Sasang Constitutional Analysis Tool (SCAT) for Sasang Constitution Diagnosis, and completed the Core Seven Emotions Inventory (CSEI) and Temperament and Character Inventory (TCI). Results: 1. From the results of the CSEI, Soeumin showed a significantly higher fear (恐) score than the Soyangin. 2. From the results of the TCI, Soeumin showed a significantly higher harm avoidance (HA) score than Taeeumin and Soyangin. Moreover, the Soyangin showed a significantly higher reward dependence (RD) score than Taeeumin and Soeumin. 3. In the correlation tests of the CSEI sub-scales, there was negative correlation between joy (喜) and other emotions, which are thoughts (思), depression (憂), sorrow (悲) and fear (恐). There were positive correlations between the emotions except joy (喜). 4. In the correlation tests of the TCI sub-scales, there was negative correlation between HA and persistence (P), and HA and SD. Moreover, there was a positive correlation between RD and cooperativeness (C) and between P and self-directedness (SD). 5. In the correlation tests of the TCI and CSEI, joy (喜) showed a negative correlation with HA and a positive correlation with P and with SD. Anger (怒) showed a negative correlation with C and other emotions except joy (喜) showed a negative correlation with RD. Conclusions: The differences of psychological characteristics in Sasang Constitution were shown with CSEI and TCI from this study.

Objectives: S-HTP is a projective test of cognitive activity. The purpose of this study was to examine the response characteristics in the S-HTP test as they related to seven emotions and cognitive processes. Methods: 153 students underwent S-HTP testing. 10 students were excluded and a total of 143 students' data was used for the study. 143 students were classified into four groups by SCAT. A survey was conducted on seven emotions and cognitive processes painting the Whole picture, house, tree, and person, and after receiving IRB review exemption, the chi-square test was conducted to check homogeneity of the groups by gender and age. Finally, frequency analysis by constitution for each item was conducted. Results: The reaction characteristics of S-HTP, focusing on the seven emotions and cognitive processes detailed by Korean Medicine, are as follows: 1. The primary sentiment while drawing during S-HTP was 'Joy (hui)' followed by 'Thought (sah)'. 2. The sentiments while painting during the S-HTP test, and the emotions of looking at the picture after the S-HTP test, increased in 'Joy (hui)' and decreased in 'Thought (sah)'. 3. 'Thought (Sah)' was the highest scored process while drawing S-HTP, followed by 'jee (智)'. However, 'ryeo (慮)' was similar to 'jee (智)' in an unclassifiable constitution. Conclusions: The primary characteristics of the S-HTP test response are 'Joy (hui)' and 'Thought (sah)' in emotion, and 'sah (思)' and 'jee (智)' in cognitive processes. Therefore, it is necessary to verify this during the S-HTP test.
