휴대 기기가 고기능화, 다기능화 됨에 따라 다양한 멀티미디어 기능이 요구되면서 배터리를 보다 장시간 이용하면서 더 높은 전력과 에너지가 요구되고 있다. 이에 따라 여러 개의 리튬이온 cell을 연결한 배터리팩이 많이 사용되고 있다. 2개 이상의 cell로 구성된 리튬이온 배터리를 안전하게 사용하기 위해서는 과전압 및 과전류, 고온으로 부터 보호해야 됨은 물론, 수명을 연장하기 위해서 각 cell의 전압을 같게 유지시켜주는 balancing 기능이 반드시 요구된다. 본 논문에서 제안한 IC는 모바일 기기뿐만 아니라 E-bike, 하이브리드 자동차, 전기 자동차 분야에도 적용 가능할 것으로 예상되며, 국내 PMIC 발전에 기여할 것으로 기대된다.

The single cell gel electrophoresis (comet) assay is one of the useful tools for the study of genetic damage in humans exposed to environmental mutagens and carcinogens. This study was undertaken to evaluate the status of DNA damage in peripheral lymphocytes depending on their sex, age, smoking habits, and other factors in normal healthy Korean population. The 99 volunteers included in the study and out of these, 36 volunteers were smoker and 63 volunteers were non-smoker aged between 20-59 years. All individual answered a questionnaire that assessed their general information including smoking habits and the extent of the environmental tobacco smoke (ETS) exposure, and blood samples were obtained. There was a statistically significant difference in the extent of DNA damage between smoker and non-smoker (p<0.001). A significant difference was also observed between male and female (p<0.001) and amongst the different group of age (p<0.005), however, correlation analysis showed that only smoking habit was a significant factor for DNA damage. No significant effect of smoking duration, number of cigarettes smoking a day, SPY (smoke pack years) in smokers and environmental tobacco smoke exposure in non-smokers on the status of DNA damage was observed.

Although considerable research has been done on the blood picture of the horse, hot-blooded and cold-blooded, little work has been made of the blood picture of the army pack horse, Jeju horse. The object of the present investigation was to make good this deficiency, and to suggest standard for the blood picture of army pack horses kept under the regular military training and the ideal feeding in the heart of a mountain. Blood samples were drawn from the jugular vein through a 15-gauge bleeding needle from 41 males and 28 females, aging 3 to 9 years old. It was taken between seven and nine o'clock in the morning. Animals were handled as quietly as possible to avoid any excitation. No restraint other than a halter was used. Enumeration of erythrocyte, total and differential leukocyte count, determination of hemoglobin in blood, and the value of packed cell volume were male in the usual manner, and erythrocytic constant was calculated by the method of Wintrobe. Erythrocyte count was $7.83{\pm}0.20(4.95{\sim}11.05){\times}10^6/mm^3$(SE). This value was much lower than hot-horses, but slightly higer than the values of cold-horse reported from foreign country. Concentration of hemoglobin in blood was $13.0{\pm}0.33(9.5{\sim}17.8)g/100ml$. This value was much higher than that of cold-horses observed by the other authors, approaching to the values of hot-horses. Packed cell volume was $32.1{\pm}0.92(22{\sim}42)ml/100ml$. This vague was a little higher than that of the other cold-horses. Mean corpuscular volume was $41.5{\pm}1.20(26.6{\sim}59.3){\mu}m^3$. This value matched so well with the other results recorded by various investigators. Mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration were $16.9{\pm}0.43(12.3{\sim}25)$ pg and $41.0{\pm}0.45(29.1{\sim}51.1)g/100ml$, respectively. These values were significantly higher than the values found by the other investigations. Total leukocyte enumeration was $10.5{\pm}0.41(5.6{\sim}17.9){\times}10^3/mm^3$, being considered as normal. And differential leukocyte count of neutrophil was $44.5{\pm}2.23(15{\sim}76)%$, $5,527{\pm}234(2,231{\sim}9,144)/mm^3$, of lymphocyte $50.5{\pm}1.19(19{\sim}77)%$, $4,307{\pm}125(1,456{\sim}11,098)/mm^3$, of monocytel (0~4)%, $105(0{\sim}352)/mm^3$, of eosiophil 3.2(0~14)%, $340(0{\sim}1,232)/mm^3$ and of basophil 0.25(0~3)%, $23(0{\sim}236)/mm^3$. The percentage of the differential count obtained from the present work showed a good agreement with the results of various authors. Of the horses examined monocyte was found from 42 horses, eosinophil from 62 horses and basophil from 10 horses. No significant differences recognized between male and female horses, and the effect of age was not observed between three to nine years old. Judging from the blood picture of the present investigation, it could be stated that the army pack horses on training were kept better than the average farming conditions.

The purpose of this study is to observe the effects of ice-pack application on different body areas and to note which body area produces the best results according to age, room temperature, sex and disease. Seventeen patients, including six men and eleven women, hospitalized at Seoul National University Hospital from May 22 to August 29, 1971, ranging in age from 15 through 60 years with an oral temperature of 38℃ or over, were chosen for this study. They were observed with regard to the effect of the ice-packs after applications for 30, 45 or 60 minutes. Four ice-packs, 7.6inch by 9 inch, were applied on the chest and the abdominal surface in the control group and the same size and number of packs on the axillae and political regions in the experimental group. The study results were reviewed in a statistical method to obtain the following findings 1. There was no significant difference in the change of the body temperature between the control group and the experimental group after applying the packs for 30, 45 or 60 minutes. 2. Individually, there was a significant difference in the change of body temperature between before and after application for 30, 45 or 60 minutes. 3. The difference of room temperature also had no merle influence on the body temperature taken immediately before applying the ice-packs. Even when ice-packs were applied for 30, 45 or 60 minutes, the room temperature did not influence the reduction of temperature in the patient. 4. There was a significant difference in the change of the body temperature, according to the sex, after application for 30, 45 or 60 minutes. Male patient's body temperature decreased far more noticeably than the female patients and the degree of reduction became more pronounced the longer the packs were applied. 5. In regard to age, in adults, the degree of reduction in the body temperature by the application of ice-packs was similar after appling them for 30, 45 or 60 minutes and did not depend upon the length of application. 6. Regardless of the disease, there was no great difference in the reduction of body temperature when the ice-packs were applied for 30 or 45 minutes, except for patients with typhoid fever when a striking decrease in the fever resulted after a 60 minute application of the ice-pack.

A 42-year old male patient was referred to the Department of Oral Medicine, Kyungpook National University Hospital due to the chief complaint of limite mouth opening. Three years ago, the patient was diagnosed as an infarction of both cerefellar hemispheres, acute obstructive hydrocephalus and acute epidural hematoma of frontal lobe at the department of neurosurgery.Both of the infarcted cerevellar hemispheres and the epidural hematoma of frontal lobe were removed with suboccipital and frontal craniectomu. After the brain surgery jaw opening range was decreased progressively and ultimately mouth opening became almost impossible. Spasmodic and rhythmic contractions of the masseter muscles occurred intermittently during daytime as well as sleeping. Food intake was available only through Levin -tube. Actibe jaw opening exercise was prescribed with the aids of tongue blades. A moist hot pack and indomethacin phonophesis were also applied 20 minutes three times a day to decrease discomfort muscle activities. After a month of treatments, the opening range was increased to 5mm at the premolar area and oral food intake was possibel. The L-tube was removed and the patient was discharged.
