Third, the participation motivation is partially influences on the body esteem of female university students participating in leisure sports. Lastly there is a causal relationship among objectified body consciousness, participation motivation and body esteem of female university students participating in leisure sports.

Adaptive ARQ Method for Enhancements of LTE MAC Protocol

정용학,권영미 한국멀티미디어학회 2016 멀티미디어학회논문지 Vol.19 No.12

In layered communication architecture, each layer is designed to service its own functions to higher layer while getting serviced by lower layer. Usually layered architectures are not optimized in a total view of whole services and functions. So cross layer design pursues performance enhancements by optimizing in various ways. In LTE, MAC layer uses HARQ mechanism and RLC layer uses ARQ mechanism for retransmission. According to the 3GPP 36.331 specification, two layers’ cooperation may not happen in an optimized way. This paper suggests an adaptive MAC layer approach which RLC layer’s function might be initiated in MAC layer in advance to utilize MAC layer’s idling wasting time for RLC layer’s next decision. This adaptive ARQ method in MAC layer speeds up the next retransmission and reduces the overall transmission time. Emulation shows the improved performance in total retransmission time and retransmission success ratio. In wireless shadow area, the retransmission occurs frequently. Our approach has strong points in this poor wireless condition.

한국방송통신대학교 자체평가 연구(2015~2016학년도) : 대학 및 연구소를 중심으로

대학구조개혁평가가 지나치게 세부적인 부분까지 평가를 하면서 대학의 자율성을 위축시키고 평가수행 자체에 과도하게 부담을 주어 이에 대한 개선이 필요하다는 대학의 요구가 반영되면서 대학자체평가는 평가지표를 축소하여 실효성 있는 평가 체게로 변화하고 있다. 이에 실효성 있고 원격대학의 특수성을 반영하는 평가지표로 간소화하고자 지금까지 실시된 우리대학의 자체평가 지표를 분석, 검토하여 평가지표를 재구조화하고 2015~2016년도를 기준으로 자체평가를 수행하였다. 대학자체평가 지표의 문제점 및 개선 방향은 아래와 같다. 첫째, 평가지표가 지나치게 세분화되어있다. 둘째, 중복되는 지표의 삭제 또는 재구조화가 필요하다. 셋째, 평가지표의 축소에 따른 배점 재조정이 필요하다. 넷째, 지표명과 평가 내용이 잘 부합되도록 수정이 필요하다.

Objectives: Allergen is closely related with local features and cultural environment and a new apporach method regarding causes triggering aggravation is especially required due to complex and variety of ordinary residence and pollution of living environment recently. We, therefore, performed this study to inspire the necessity of identification of causative afeuts in aothmatic patiends in pusan area. Methods: We measured serum specific IgE antibody by means of chemiluminescent analyzer employing MAST, classified the level from class 0 to 4 and interpreted the result in order to ideutify allergen on total 262 patients consisted of inpatients and outpatients who had been presumed as extrinisic asthma and treated in this hospital during 2 and a half years from June of 1994 to December of 1996. Results: 1. With regard to sex and age distribution, the rate of men versus women was 1: 1.3, while in the distribution by age, the twenties and the thirties were the most as 29 % and 26% respectively. 2. The result of interpretation of the test showed positive in 75%, 78% of which showed positive reaction compounded of 2 kinds or more. 3. If we take a look at the distribution of total IgE class in the positive area, we can find that; Class 3 l and class Il showed the highest frequency as 47% and 37% respectively. 4. If we take a look at the distribution by age and allergen, the twenties(32% ) and the thirties(30%) showed the highest frequency, the fifities, the forties and the teens showed middle frequency as 10 13% and the sixties and the seventies showed the lowest frequency as about 1%. The causat ive allergen appeared in the order of pollen(40%), dust(20%), food(18 % ), fungus(13% ) and epidermis(8% ). 5. The distribution of allergen by season generally showed high rate of positive appearance in spring and fall as pollen appeared in spring(44%) and fall(27%), dust appeared in fall(32%) and summer(23%), food appeared in spring(34% ) and fall (29% ), fungus appeared in fall(.30% ) and spring(28% ) and epidermis appeared in spring(30%) and fall(28 %) 6. With regard to the allergen.' (1) In pollen allergens, trees showed higher positive frequency than weeds and trees were in the order of birch(14%), alder(13%) and hazelnut mix(12%) and weeds showed similar positive values. (2) In dust allergens, mite(D. pteronyssinus and D. farinae) showed high positive rate as 39% each. (3) In epidermal allergens, it also showed relatively even positive value among which cats hairdandruff was the highest as 40%. (4) In food allergens, shrimp showed the highest as 22 % and others were similar as evenly positive values. (5) In fungus allergens, Candida and Stemphylium showed the highest value as 19 % each. Conelusion: The analysis of allergen by means of MAST could be used as a valuable guide post for identifging cousative antigens for active treatment of extrinsic asthma.

Nephrocalcinosis is a condition characterized by the deposition of ealcium salts intracelluarly and extracellularly in kidney. The localization of the calcium deposition may vary, but it usually involves the medulla and corticomedullary area and occasionally the cortex. Cortical nephrocalcinosis is rarer than the medullary variety and usually the result of severe destructive cortical disease such as acute cortical necrosis, chronic glomerulonephritis or chronic pyelonephritis. The mechanism of nephrocalcinosis are not clear, but prolonged hypercalcemia and/or hypercalciuria, excess circulating parathyroid hormone, impaired urinary acidification, impaired proximal tu- bular calcium reabsortion, and local injury to renal parenchyma are the factors that can predispose to nephrocalcinosis. We experienced a patient with macroscopic cortical nephrocalcinosis associated with membranoproliferative glomerulonephritis and liver cirrhosis due to hepatitis B virus. There have been no report of cortical nephrocalcinosis with chronic glomerulonephritis in Korea, therefore we report this case with a review of some literatures.

Systemic lupus erythematosus is a disease of unknown cause which involves various organs and primary involvement of urinary bladder is very rare. We experienced a case of a female patient with SLE and urologic manifestations (interstitial cystitis, hydroureters and hydronephrosis), which were resolved spontaneously without any immunosuppressive therapy. There was no significant correlation between clinical course and disease activity index.

Hereditary spherocytosis is the most common form of congenital hemolytic anemia, which is characterized by spheroidal red blood cells, increased osmotic fragility and splenomegaly. The development of protein research revealed various primary defect resides in the erythrocyte membrane proteins of the spherocyte. Recently, we studied a 36-year-old male hereditary spherocytosis patient with anemia and splenomegaly, Analysis of the erythrocyte membrane proteins by SDS-PAGE showed a deficiency of protein 4.2.
