남과의 비교는 스스로 평가에서 나온다. '나는 ${\bigcirc}{\bigcirc}{\bigcirc}$보다 못난이야'. '나는 ${\bigtriangleup}{\bigtriangleup}{\bigtriangleup}$보다 무능해' 그러면서, 남과의 비교는 '자신을 어떤 시각에서 보느냐'에서 시작된다. '나를 어떤 관점으로 보고 있는가?' 남과의 비교는 그만두고 내 안의 장점을 바라보는 자세가 필요하다.

유전적으로 당뇨병이 될 소질이 있어도 스트레스,무절제등의 환경요인이 덧붙지 않으면 평생을 당뇨병을 모르고 지내게 되는데,문화의 발달에 따라 그러한 환경요인들은 보다 자주,보다 강하게 밀려오고 있어,당뇨병은 문화의 발달에 따라 그 빈도가 늘고 있다.

This study investigated the quality change in dry aged beef cattle loins (temperature: $3{\pm}1$, lative humidity: $75{\pm}5%$, period: 14 days), compared to non-aged beef cattle loins (control). The water content of dry aged loins was lower than that of the control (p<0.001). The fat content, protein content, pH value, and redness in dry aged loins were higher than in the control. Moreover, dry aging significantly improved the water holding capacity and cooking yield of beef cattle loin (p<0.001). The shear force of dry aged loins was significantly lower than in the control (p<0.01). The flavor, tenderness, juiciness, and overall acceptability of dry aged loins were higher than in the control according to sensory evaluation. Therefore, dry aging can improve the quality properties of beef cattle loins.

This paper showed the difference in the optimum conditions by using the ANSYS CFX simulation program with the changes of the main-blade angle and sub-blade angle. Main-blade Shape 4,which had angle $45^{\circ}$ while other Shapes with angle $0^{\circ}$, was increased to 157.2[%] to 263.2[%] in the power and was increased to 110[%] to 250[%] in the power coefficient. Moreover, when the Shape 5 Fin length of main-blade doubled, the power was 70.8[%] when compared with Shape 1 and 27.5[%] with shape 4.If the main-blade geometry equals shape 1 in the case structure, The power of Case1 was increased to 13.3[%] when compared with Case2. Also, the power coefficient was increased to 15.4[%]. When sub-blade angle was $45^{\circ}$, main-blade was better than the Fin type than the Bended type. The power of Case4 was increased to 47[%] when compared with Csae1 and increased to 13.6[%] with Case 3. Also, the power coefficient was 46.7[%] when compared with Case 1 and 15.8[%] with Case 3.

New institutionalism is one of the research perspective, explaining political, economic, social phenomena through institutions. It is seeking more accurate diagnosis and solution of societal problem. What is good media for community? And how it should be operate? These questions are related to design and improvement of media system. Now we need to better approaching method for higher explanatory power about media institutions. From this context, the purpose of this study is exploring application of new institutionalism to media system. The major findings are as follow: At first, the new institutionalistl approaches can be apply the research fields of media policy/law and media organizations. Two, we suggest main research questions and research methods to each of that. This study has implication as more systematic and integrated approach to the research fields of media institution.

Private Security Guard Certification Exam that initiated as the eligibility of private in 2006, has been requested more fulfilling management because that becomes to be recognized at the national certified qualification system in 2013. The findings of this study were as follows: First, it is necessary to expand more exemptions, currently some are mainly police officers. Secondly, it is needed to make to announce the final successful candidates through the opposition proceedings by publishing assumptions answer of the problem and by improving the procedure for determining the successful candidates, and so forth.

In order to manufacture of soy paste, Changes of chemical composition and enzyme activity of soybean by different processing method were investigated. The results are summarized as follows: Changes of chemical compositions were; Raw(A) and soaked(B) soybeans contain about 2% of more crude fat than roasted(C) and steamed(D) soybeans, roasted and steamed soybeans contain $1.16{\sim}1.74%$ of more protein than those of raw and soaked soybeans, and Raw and roasted soybeans contain $0.11{\sim}0.41%$ of more crude fiber than those of soaked and steamed soybeans. ${\alpha}-amylase$, ${\beta}-amylase$, protease, lipase activity of raw and soaked soybeans were $2{\sim}5$ folds higher than those of roasted and steamed soybeans. Trypsin inhibitor activity of raw, soaked, roasted and steamed soybeans was indicated 56.7%, 42.9%, 32.9% and 20.8% in the order, respectively.

This study was to investigate the eating attitutes, food habits, perceived stress of high school students. Three hundred and fifty four high school students in Seoul area were surveyed to obtain the information from Sep. 18 to 26 in 1997. The average height and weight of high school students were 173.7 cm, 62.9 kg for male students and 162.5 cm, 52.6 kg for female students. The 52.5% of high school students were normal weight and 41.5% of them were underweight. Female students(46.7%) showed higher proportion of underweight than male students(37.0%). The students(50.9%) ate breakfast irregularly and most students(92.5%) ate Korean food for breakfast. The dietary changes of high school students over past few years showed that the intake of vegetable, fruit and yogurt were increased. The food habit score showed no significant difference by gender, mother's employment and monthly spending money. The nutritional knowledge score of female students were higher than the score of male students. Most high school students(93.9%) were highly stressed in their living. The stress score(3.35) of female students were higher than those of male students(3.15). However, excercise, eating slowly and good appetite could lower their perceived stress.

The present study was undertaken to evaluate the effect of indigestible dextrin on bowel function and serum lipid. Recently developed indigestible dextrin is water soluble dietary fiber obtained by heating and enzyme-treatment of potato starch with low viscosity. SD male rats weighing 80~85g were divided into three groups; control diet(IC), control +5% pectin(IP), control +5% indigestible dextin(ID). Experimental rats were fed one of the experimental diets ad libitum for six weeks. Weight gain, food intake, and food efficiency ratio were not significantly different among other groups. Those of ID tended to be higher than in IP and IC. Weights of liver, spleen and kidney were not significantly different among groups. Epididymal fat pads weight in W and ID tended to be lower than in IC. The weight of cecum was sinificantly higher in m than in other groups(p<0.05). The weight and length of large intestine tended to be higher in IP and ID than in IC. Total feces excretion of ID and If tended to be more than that of IC. Transit time was shorter in IP than in other groups. Serum total lipid, total cholesterol and TG levels were higher in IC group than other groups. The fecal excretion of lipid was significantly higher in IP than in other groups(p<0.05). That of ID tended to be more than that of IC, so fat apparent absorption of ID was lower than that of IC. Ca absorption were decreased more in IP than in other groups(p<0.05).

A field experiment has been carried out to evaluate the residual effect of zinc fertilizers by rice plant grown under flooded conditions in the field. The results obtained are summarized as fellows ; Residual effect of zinc fertilizers on yields of rough and hulled grains showed slight increases. Effect of zinc application methods on yields of the grains were shown that zinc mixed treatment could be more effectively utilized than treatment of zinc on the soil surface. In case of levels of zinc application, 5 kg zinc per hectare represented high yields of the grains than those obtained from 10kg and 20kg zinc placement per hectare respectively. Regarding the form of zinc fertilizers, the urea-zinc complex showed less effective on yields of the grains than did the zinc sulfate. This phenomenon was consistent with the previous result. Yields of total zinc in rice plant grown on the rice straw added soils (Treatment No. 2 and 8) and the urea-zinc complex treated soil were increased markedly as compared to those data obtained from the previous year. The percentage of zinc derived from fertilizer decreased largely as compared to that of the first year crop. The yield of fertilizer zinc in rice plant decreased slightly in the most zinc treatments but in the case of treatments of zinc mixed with the straw added soil and the urea-zinc complex increased reversely as compared to the previous results. The mixed application of zinc with soil showed higher yield of fertilizer zinc than the soil surface placement. Approximately from 4.6 to 24.3 per cent of zinc taken up by rice plants were derived from the fertilizer zinc. Zinc fertilizer use efficiency ranged from 0.213 to 0.584 per cent when 5 kg zinc per hectare applied.
