Since any exercise program is related with health, we cannot but take into consideration the efficiency of fat consumption. This study was aimed at determining the effects of the exercise programs combining jogging and weight training on nutrient-wise energy consumption in order to facilitate consumption of fat during exercise. To this end, 10 male students attending department of sports science of T University located in Incheon were sampled to be subject to exercise programs combining jogging and weight training. The subjects were urged to do weight training before jogging or vice versa. Then, intake of oxygen and output of carbon dioxide were measured after each session to analyze the amount of carbohydrate and fat based on the breathing exchange rate. The results of this study can be summarized as follows; There was found no significant difference of oxygen and calorie consumption between two exercise programs, but carbohydrate was more consumed by weight training after jogging, while fat was more consumed by jogging after weight training. During rest after exercise, more oxygen, carbohydrate, fat and calorie were consumed when weight training followed jogging, and during recovery time, more oxygen, carbohydrate, fat and calories were consumed when jogging followed weight training.

The tunneling barrier is crucial to the overall performance in magnetic tunnel junction. We have suggested a new formation method for the tunnel barrier, which has utilized pseudo atomic layer deposition with sputtering (PALDS). As is well known, all metallic thin films oxidize more or less under atmospheric conditions. With using this property of metallic thin films, we have prepared tunnel barrier by sputtering metallic thin film and exposing it to the oxygen ambience. From transmission electron microscopy (TEM) observation, the formed tunnel barrier has been confirmed to have clear and good interface between magnetic layers and tunnel barrier. From atomic force microscopy (AFM) observation, it has been also confirmed to have low surface roughness. The TMR MRAM cell manufactured using PALDS method has been shown to exhibit typical tunnel resistance of 86 KΩ·μm^2 and TMR ratio of about 40%. The 40% of MR is quite large. It is considered that this value is geometrically enhanced magnetoresistance due to the low junction resistance of MTJ.

진공증착방법으로 제작한 Ni_53-Fe_47 박막에 관한 신형전류자기 기전력효과의 전류와 자장 방향이 만드는 각 θ 의존성이, 자기저항효과의 cos 2θ, Hall 1 효과의 경우 sin 2θ로 관측되고, 이 효과의 자장에 의존하는 전압변화율이 자기저항효과와 비교할 때 차수가 다르게 큰 것이 조사된다. 이 효과가 2 Carrier형 모델로 이해할 수 있음을 이론적으로 확인된다. A new Galvanomagnetic electromotive force effect of Ni_53-Fe_47 thin films is studied. The dependence of this effect on θ, angle between the current and the magnetic field, is found to be the form of sin 2θ, in contrast with that of the magnetoresistance effect cos 2θ and that of the Hall effect sin θ. Property of this effect is that the rate of the voltage variation depending on the magnetic field is extremely large as compared with the magnetiresistance effect. It is theoretically confirmed that this effect is well understood on the basis of the two carrier types model.

Background and Objectives : Branchial cleft anomalies are encountered rarely in clinical practice. We reviewed medical records of branchial cleft anomalies according to age and sex distribution, site distribution, characteristics of mass on physical examination, location of mass, preoperative diagnosis, type of branchial cleft cyst and report our experience with 25 cases of branchial cleft anomalies. Materials and Methods : A review of medical records was performed on 25 cases of branchial cleft anomalies diagnosed in pathologic report from January, 1990 to March, 2000. Result : Sex distribution was 11 male and 14 female, age distribution was most common in third decade which was 8 cases(32%). Site distribution was predominant in left side(13 cases), and in physical examination, the characteristics of the mass was nontender(76%), mobile(60%), soft(80%). The lesion site was submandibular area in 2 cases, upper 1/3 portion of sternocleidomastoid muscle(SCM) in 2 cases, middle 1/3 portion of SCM in 20 cases and parotid area in 1 case. The preoperative diagnosis was branchial cleft cyst in 16 cases, cervical lymphadenitis in 3 cases, tuberculous lymphadenitis in 3 cases, branchial cleft fistula in 1 case, dermoid cyst in 1 case and parotid mass in 1 case. Among 25 cases, first branchial cleft cyst was seen in 4 cases, second branchial cleft cyst in 20 cases and second branchial cleft fistula in 1 case. Conclusion : The clinical history of recurrent neck inflammatory episodes in young patients and nontender, mobile, soft neck mass should raise the suspicion of this entity. Investigation using CT scanning in combination with aspiration is useful. Treatment of all branchial cleft anomalies is complete surgical excision because there is lack of spontaneous regression, a high rate of recurrent infection, the possibility of other diagnosis, and rare malignant degeneration. Complete removal without complications depends on a good understanding of regional embryogenesis, a knowledge of the surrounding structure, and awareness of the different anatomical presentation.

In 2007, the Korean Society of Infectious Diseases recommended an immunization schedule for adults residing in Korea. This recommendation includes four categories: standard immunization for healthy persons, supplementary immunization for persons with underlying illnesses, recommendations for health-care personnel and for international travelers. The Standard Immunization Schedule consists of universal vaccination (tetanus-diphtheria/tetanus-diphtheria-pertussis (Td/Tdap); hepatitis A vaccine for persons aged 20s; human papilloma virus vaccine for women under 26 years old; meningococcal vaccine for military recruits and college students in dormitories; influenza vaccination for persons aged 50 years or more and pregnant women; and pneumococcal vaccination for persons aged 65 years or more) and catch-up vaccination (hepatitis A vaccine for persons aged 30s; hepatitis B vaccine, varicella and MMR vaccines for persons who have uncertain specific immunities). The Supplementary Immunization Schedule recommends 4 vaccines, i.e., pneumococcal, influenza, meningococcal, and Haemophilus influenzae type b, appropriate to the underlying illnesses, and confirmation of the presence of antibodies to hepatitis A and hepatitis B. The Recommendation for Health-Care Personnel includes universal vaccination (influenza and pertussis) and catch-up vaccination (hepatitis B, measles-mumps-rubella and varicella for seronegative health-care personnel). The Recommended Immunization for International Travelers focuses reinforcement of vaccinations for healthy persons and includes certain immunizations necessary for international travel (yellow fever, meningococcal, plaque, tick-borne encephalitis, and cholera). These guidelines can be seen at www.ksid.or.kr.

Objective : Squamous cell carcinoma of the head and neck represents approximately 2.0∼4.0% of all malignant tumors, with an etiology closely associated with smoking, drinking and various genetic alterations. The purpose of this study was to investigate the correlation of MIB-1, p53, bcl-2 and apoptosis according to degree of differentitation of squamous cell carcinoma. Methods and Material : forty-eight cases of squamous cell carcinoma of the head and neck were selected for this study. MIB-1, p53, bc1-2 expression rate were studied by iromunogistochemical staining and the number of apoptosis observed by TUNEL method. Results : The expressioins of MIB-1, p53, bcl-2 and apoptosis were found in 56.3%, 50.0%, 14.6%, 85.4%, of 48 cases of squamous cell carcinoma, respectively. The expression of MIB-1, p53 and apoptosis were more higher in poorly differentiated cases than well differentiated cases. MIB-1 expression was related with p53 mutation (p<0.05) and apoptosis rate(p<0.05). Conclusion : From these results. the expressions of MIB-1, bcl-2 and apoptosis were related with degree of differentiation of squamous cell carcinoma and correlation among these parameters.

The purpose of this study, as a part of an intergrated human-robot ergonomics, is to improve robot motion control in a teaching and operating expert system / world coordinate system (TOES / WCS) constructed in the previous study. The major contribution of this study reduces the inaccuracy in coordinate reading and the movement time of robots in macro motion control. This study also reduces undesirable teaching time required by using a unit control (UC) and micro unit control (MUC) in micro motion control.
