Background/Aims: Recent epidemiologic studies have shown a continued increase in colorectal cancer incidence among younger adults. Little is known about the factors that contribute to the development of young-onset colorectal neoplasia (CRN). Methods: A cross-sectional analysis was performed for individuals younger than 40 years who underwent colonoscopy in Seoul St. Mary’s Hospital and its affiliated health screening center. High-risk CRN was defined as adenoma or sessile serrated lesion ≥ 10 mm, with three or more adenomas, villous histology, high grade dysplasia, or carcinoma. Results: Of these 13,621 included participants, 2,023 (14.9%) had one and more CRN. Young patients with CRN tended to be elderly, male, obese, smoker, having a habit of drinking, and having comorbidities such as hypertension, dyslipidemia, diabetes, and chronic kidney disease. In a multivariate analysis adjusted for age, sex, obesity, smoking status, and alcohol intake, old age (odds ratio [OR], 1.086; 95% confidence interval [CI], 1.054 to 1.119), male sex (OR, 1.748; 95% CI, 1.247 to 2.451), obesity (OR, 1.439; 95% CI, 1.133 to 1.828), and smoking (OR, 1.654; 95% CI, 1.287 to 2.127) were independent risk factors for overall CRN. Obesity and smoking as two modifiable factors increased the risk for high-risk CRN even more than for overall CRN (OR, 1.734; 95% CI, 1.168 to 2.575 and OR, 1.797; 95% CI, 1.172 to 2.753, respectively). Conclusions: Obesity and smoking were modifiable risk factors for CRN in young adults. They increased the risk for highrisk CRN even more than for overall CRN. A colonoscopy might be beneficial for young individuals with these factors.

In order to investigate to develop the new dosage form of the traditional herbal medicine which have been used for the treatment of disease in oriental medicine, we conducted a survey on 217 patients who visited oriental hospital in Kyung Hee University Medical Centre during one month since October 2003. They were given questionnaires to answer and results of this study were as the following: 1. About 45% patients visited in oriental hospital believed that oriental medicine was better remedy than modern medicine. 2. Most of patients felt that the oriental medical expenses were expensive. 3. About 60% patients preferred the modernized dosage form such as extract powder and granule, etc. rather than medicinal herbs in package. 4. Most of patients hope that decoction of medicinal herbs in package would change the advanced dosage forms such as tablet, capsule and extract powder, Because patients suffered from inconvenience of making a decoction, unhandy, unwieldy and keeping. 5. About 60% patients pointed out that merits of advanced dosage forms of medicinal herbs were convience to take and handy, etc.. However, they had an Intension that there were some difference of efficacy between decoction and modernized dosage forms of oriental medicine. Because of several defects such as unusual flavor and smell, incompatible food, large volume with amount, inconvenience of carrying and decocting oriental herbal medicines, most of patients would expect the development of the advanced dosage forms of them. In summary, this study show that it was needed to develop the new dosage forms of oriental herbal medicine on the basis of scientific research and economical cost of medical expenses.

This study was performed to evaluate the temperature rise on various position of the Buchanan plugger, the peak temperature of plugger's type and the temperature change by its touching time of heat control spring. The heat carrier system 'System B' (Model 1005. Analytic Technologies, USA) and the Buchanan's pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200℃ which Dr. Buchanan's "continuous wave of condensation" technique recommended on digital display and the power level on it was set to 10. In order to apply heat on the Buchanan's pluggers, the heat control spring was touched for 1, 2, 3, 4 and 5 seconds respectively. The temperature rise on the surface of the pluggers were measured at 0.5 mm intervals from tip to 20 mm length of shank using the infraed thermography (Radiation Thermometer-IR temper, NEC San-ei Instruments, Ltd, Japan) and TH31-702 Data capture software program (NEC San-ei Instruments, Ltd, Japan). Data were analyzed using a one way ANOVA followed by Duncan's multiple range test and linear regression test. The results as follows. 1. The position at which temperature peaked was approximately at 0.5 mm to 1.5 mm far from the tip of Buchanan's pluggers (p<0.001). The temperature was constantly decreased toward the shank from the tip of it(p<0.001). 2. When the pluggers were heated over 5 seconds, the peak temperature by time of measurement revealed from 253.3±10.5℃ to 192.1±3.3℃ in a touch for 1 sec, from 218.6±5.0℃ to 179.5±4.2℃ in a touch for 2 sec, from 197.5±3.0℃ to 167.6±3.7℃ in a touch for 3 sec, from 183.7±2.5℃ to 159.8±3.6℃ in a touch for 4 sec and from 164.9±2.0℃ to 158.4±1.8℃ in a touch for 5 sec. A touch for 1 sec showed the highest peak temperature, followed by, in descending order, 2 sec, 3 sec, 4 sec. A touch for 5 sec showed the lowest peak temperature (p<0.001). 3. A each type of pluggers showed different peak temperatures. The peak temperature was the highest in F type and followed by, in descending order, M type, ML type. FM type revealed the lowest peak temerature (p<0.001). The results of this study indicated that pluggers are designed to concentrate heat at around its tip, its actual temperature dose not correlate well with the temperature which Buchanan's "continuous wave of condensation" technique recommended, and finally a quick touch of heat control spring for 1 sec reveals the highest temperature rise.

This paper deals with the differences between the thermal stabilities of myofibrillar proteins of dorsal ordinary muscle and lateral dark muscle in yellowtail, Seriola quinqueradita. The myofibrillar proteins submitted to this experiment were extracted by the modified method using Triton X-100 detergent. Effects of temperature on the stabilities of the myofibrillar proteins were investigated by analysing ???-ATPase activity. The denaturation velocities and thermodynamic parameters of each of the proteins were compared. Lipid content and ???-ATPase activity of the myofibrillar protein of the ordinary muscle were found to be 0.09% and 0.205-0.225μM-Pi/min/mg-protein, respectively, while those of the dark muscle were 1.70% and 0.231-0.240μM-Pi/min/mg-protein. The relationship between the inactivation of ???-ATPase activity of the myofibrillar proteins and the increase in temperature showed a good first-order reaction. The half-life of ???-ATPase activity on the myofibrillar protein showed in general that the protein of the ordinary muscle is more stable than that of the dark muscle. Activation energy, activation enthalpy, activation entropy and free energy of the protein at 25℃ were 5,500 cal/mol, 4,900 cal/mol, -44.51 e.u. and 18,100 cal/mol, respectively for the ordinary muscle, and 5,390 cal/mol, 4,800 cal/mol, -44.17 e.u. and 17,900 cal/mol, respectively for the dark muscle. It may be concluded that an increase in temperature affects substantially to entropy of the proteins. The myofibrillar proteins of the both muscles found to be more stable at -30℃ than at 0℃ and -15℃.

최영보 한밭대학교 2004 한밭대학교 논문집 Vol.21 No.-

The charms of Chosun Dynasty were made for the purpose of checking the state of casting for legal coin "Sangpyung-tongbo" or to celebrate the happy events of royal family. Then they were owned preciously by the family of aristocratic class "yangban" as a mascot for decoration. The patterns casted in charms are characters, flowers and leaves, animals etc. and the meaning of them are the pray for long live, wealth, many sons etc., or the educational messages based on the Confucian ideas. This paper tries to classificate the charms according to their shapes and patterns, and analysis the symbolic images of pictorial patterns expressed in some selected charms in Chosun Dynasty. The patterns of charms showed in this paper can be used for basic data for modern designing.

최보가,문영경 대한가정학회 2004 Human Ecology Research(HER) Vol.42 No.1

The purposes of this study were to investigate the quality (structure and process) of home-based day care and center-based day care, and to examine socioemotional development among infants who were in both types of day care. The subjects of this study were 101 infants who were in home-based day care and 181 infants who were in center-based day care. The measurements were socio-emotional development scale and assessment scales for day care programs. Results indicated that, first, home-based day care did not significantly differ from center-based day care in terms of structure. Second, home-based day care were, to some degree, significantly different from center-based day care in the process: home-based day care had better play environment and play activities than did center-based day care. Lastly, there were significant differences in socio-emotional development among infants according to the type of day care: infants in home-based day care were more independent to their teacher and felt more secure in child care homes than was true for the infants in center-based day care.
