The present experiments were carried out to elucidate the effects of hypophysectomy and subsequent administration of sex hormone on thyroid, adrenal gland, gonads and blood plasma components in the rat. The jresults obtained were summarized as follows: The weight of the thyroid gland of both male and female hypophysectiomzed rats decreased markedly from 7 days up to 56 days after the hypophysectomy as compared to the control group. The administration of sex hormone (6 mg of testosterone propionate to male and 6 mg of hexestrol to female) to the hypophysectomized rat gave on effect on the change in the weight of the thyroid gland. The hopophysectomy decreased the uptake of radioactive iodine in the thyroid gland in both male and female rats with time. Subsequent administration of the sex hormone caused no effect. With regard to the histological changes of the thyroid gland, the hypophysectomy caused significant changes in the gland showing a remarkable degeneration. The function of the gland seemed to disa, pp.ar almost completely on 56th day after the hypophysectomy. Upon the administration of sex hormone after the hypophysectomy, however. the epithelia of the follicle which has changed to flat from has partly returned to its functional cubicfrom and nuclei recovered as nearly as normal. These recovery were more remarkable in the female than in the male. The hypophysectomy kept causing a significant decrease in the weight of the adrenal gland in male and female rats during the period of observation (up to 56 days) as in the case of thyroid gland. The administration of sex hormone has on effect in this respect either. The hypophysectomy also caused a marked morphological change in the gland: zona fasciculata and zona reticularis were dicreased in size quichly after the hypophysectomy. The administraton of the sex hormone to the hypophysectomized rat resulted in clear distinction among the three layers of the adrenal cortex which otherwise very diffused. In the male, this phenomenum was more remarkable than in the female and the pattern of the cell arrangements and the thickening of each layer became similar to those of normal rats. The gonads of both sexes have also kept decreasing in the weight and degenerated in morpohology after the hypophysectomy. However, the degenerate follicle became enlarged after the administration of hexestrol in the female. Furthermore, the vacuoles found in interstitial cells of hypophysectomized rat disa, pp.ared after the administration of testosterone in the male and the formation of spermatocytes seemed to be recovered. Hypophysectomy also caused a gradual increase in the contents of total protein, non-protein nitrogen, total lipid, cholesterol and calcium in the blood plasma with time. The concentrations of sodium, potassium and chloride in the blood did not change after the hypophysectomy. Sex hormone caused practically no change in above tendency.

The agriculture lavor forces around the big city have not enjoyed their priviliges within economic, social and cultural domains even as citizen of big city because their income shows relatively low against the big city citizen for greater efficiency, the plan on the improvement of munincipal typed agriculture has been set up into agricultural productivity and green tourism.<br/> The following are expected advantages taken from the plan.<br/> ① Farmers' income is to be increased while their welfare can be enhanced.<br/> ② Development of green tourism will provide the citizen with pleasant environment along with increase of farmers' income.<br/> ③ Regional economy can be stabilized so that the gap between city and munincipal agricultural area can be minimized.<br/> ④ Crops which is highly self-valued and represents the character of region can be developed and supported.<br/> Consequently it is inevitable to face some problems in the course of setting up the plan and putting it into practice. Listed below are some problems which need to solve.<br/> <br/> ① Restriction on the policy.<br/> <br/> Appropriate roads and resting facilities are essential to get green tourism linked with tourism resources.<br/> Green-belt policy, however, prevents the facilities concerned from developing as they are planned.<br/> In terms of financial aid, farmers' security ability can't be put up on time so that they can't enjoy the loam from the bank necessary for their project.<br/> The restriction in the law and policy should be relaxed.<br/> <br/> ② Education for the specialized leaders.<br/> <br/> The development of munincipal typed agriculture depends on the ability of specialized leaders as a vital element. They should be equipped with various abilities such as crops raising technics, organization management and operation, service, and advertisement.<br/> The institution to bring up the leaders should be established since the agricultural community is short of leaders.<br/> If not possible, the program to produce and educate the desirable leaders should be set up in the agriculture related institutions which have already established. And various priviliges should be allowed to them so that they can engage them selves only on the farming.<br/> <br/> ③ Financial Aid.<br/> <br/> There should be lots of expenses needed for special farming because there are lots of equipments used for improved method of farming.<br/> Once granted financial aid, orientation on how the loam should be recompensated should be held for the farmers concerned.<br/> <br/> ④ Campaign for the reform of consciousness of people.<br/> <br/> The campaign throughout the nation should be arranged for the people who keep purchasing low-priced goods instead of good quality local products.<br/> Civil organizations are expected to take a continuous active part in the campaign.<br/> This is the fundamental basis on which agriculture development can be realized.

This experiment was conducted to investigate the effects of treatment of various hormonal substance upon the egg laying, meat production and meat quality of two-year-old hens. 1. Effect of various hormone substances treatment on egg laying. 1) The rate of laying was significantly changed by the administration of various hormone substances ( P$lt;0.05) The laying rate of pregnant women`s urine and PM S treated group, but that of progesterone, thyroxine and Tapazol treated-group was decreased compared to the control group. 2) No significant difference in the egg weight among each treated groups was recognized. 3) S tuck on ovary 1㎝ in diameter, changed propotionally with the rate of laying and a significant difference among treated groups was recognized. 2. Effect of various gormone substances treatment on meat production and quality. 1) A significant change of body weight according to dosing with various hormone substances amonagn comparison groups, is recognised from 10 weeks after treatment, but only troxine treated group lose weight and are inferior, whereas other groups are heavier, compared with the control group, but its variation is very little. 2) A significant difference (p$lt;0.05) in carcass weight among the treated groups was recognized and the carcass weight of 5 treated-groups except thyroxin and progesterone treated-group was significantly higher than that of the control group. 3) The carcass percentage of PMS and Tapazol treated-group was significantly higher than that of the control group and there are no significant differences between the other groups and control group. 4) There was little difference of water extractives and ash content in meat component of 8 treated-groups. The crude protein of meat. was decreased a little in thyroxine and Tapazol treated-group while that of meat in estrogen, PMS and progesterone treated-group was increased a little. The crude fat contant was particularly increased in Tapazol treated-group and in the other groups it was similar to that of the control group. 3. Effect of various hormone substances treatment on the each organs. 1) A significant difference (p (0.05) in the total weigh of internal organs treated-groups was recognized. The total weight of internal organs in Tapazol and PMS treated-groups was heavier than in the control group. It is remarkably light in thyroxine treated groups. 2) There were some differences among the weight of gizzard fat and small intestine in 8 treated groups, but the changes in various organs weights were comparatively similar to those in total weight of internal organs. 3) The weight of liver, heart, pancreas and gizzard appeared generally to be in proportion to the body weight. 4) The weight of content was increased remarkably in estrogen treated-group and decreased in progesterone groups. A significant difference (p$lt;0.0.5) among the treated-groups was recognized. 5) A significant difference (p$lt;0.05) in the weight of a reproductive duct among treated-groups was recognized. The weight decreases remarkably in progesterone and Tapazol treated-groups and in the other groups it is little different from in the control group and generally tends to vary as an laying rate.

지역 방송사의 TV 프로그램에 대한 지각된 지역성과 관계성 요인이 채널브랜드 효과에 미치는 영향 광주지역 TV 뉴스 및 시사 프로그램을 중심으로

김선균 ( Kim Sunkyun ),김유미 ( Kim Yumi ) 한국지역언론학회 2022 언론과학연구 Vol.22 No.4

본 연구는 지역 방송사의 TV 뉴스 및 시사 프로그램에 대한 ‘지역성’과 ‘관계성’ 변인에 주목해 보고 시청자들의 지각된 ‘지역성’과 ‘관계성’ 요인이 ‘채널 브랜드 자산’에 어떤 영향을 미치는지 알아보고자 하는 데 그 목적이 있다. 구체적으로 광주 지상파 TV방송(KBS광주방송총국, 광주MBC, KBC광주방송)의 뉴스 및 시사프로그램에 대한 ‘지역성’ 요인(사회지리적 지역성, 글로컬리즘)과 ‘관계성’ 요인(신뢰성, 공정성, 사회공헌성, 소통성)에 따른 채널 브랜드 충성도와의 관계를 통합적으로 규명하고자 하였다. 먼저 TV 뉴스 및 시사프로그램에 대한 지각된‘지역성’과 ‘관계성’ 요인 간의 관계를 분석한 결과, 시청자들의 지각된 ‘지역성’은 ‘관계성’ 요인에 모두 유의미한 영향을 미치고 있었다. 또한 시청자들의 지역방송 뉴스 및 시사 프로그램에 대한 지각된 ‘관계성’ 요인은 ‘채널 브랜드 충성도’에도 모두 유의미한 정의 영향을 미치는 것으로 나타났다. 결국 지역 방송사 프로그램 중 가장 지역성이 두드러지는 뉴스 및 시사 프로그램에 있어 ‘지역성’과 ‘관계성’은 채널 브랜드 자산 형성에 매우 중요한 요인이라는 것이 검증되었다. 본 연구결과를 통해 향후 지역 뉴스와 시사 프로그램에 대한 차별화 전략으로서의 ‘지역성’ 구현과 지역방송 위기 극복 방안으로서의 지역방송과 지역민간의 ‘관계성’ 요인의 중요성을 강조할 수 있는 이론적 근거를 마련한 데 의의가 있다. This study pays attention to the variables of ‘locality’ and ‘relationship’ for TV news and current affairs programs of local broadcasters, and examines how the factors of ‘regionality’ and ‘relationship’ perceived by viewers affect ‘channel brand loyalty’. Specifically, the purpose of this study is to comprehensively identify the relationship between ‘locality’ factors (socio-geographical regionalism, glocalism) and ‘relationship’ factors (reliability, fairness, social contribution, communication) and channel brand loyalty. First, as a result of analyzing the relationship between perceived ‘regionality’ and ‘relationship’ factors for TV news and current affairs programs, viewers' perceived ‘locality’ had a significant effect on all of the ‘relationship’ factors. In addition, it was found that the perceived ‘relationship’ factor of viewers' local news and current affairs programs had a significant positive effect on ‘channel brand loyalty’. In the end, it was confirmed that ‘locality’ and ‘relationship’ in local news and current affairs programs are very important factors in forming channel brand equity. The result of this study is meaningful in that it revealed that the ‘relationship’ factor between local broadcasters and local residents is very important as a way to overcome the crisis of local broadcasting while realizing ‘locality’ as a strategy differentiated from local news.
