茅亭이 農村社會經濟에 미친 影響

崔在律 全南大學校 湖南文化硏究所 1966 호남학 Vol.4 No.-

湖南文化의 産物로서 全羅道地方에 集中的으로 存在하는 茅亭에 關하여 前記 硏究方法에 依한 要領으로 茅亭의 性格과 機能, 그리고 茅亭이 農村 社會經濟에 미친 影響 等을 分析 考察한 바 다음과 같은 內容의 結論에 到達하였다. (1) 茅亭은 部落入口 또는 農場과 部落間의 바람이 잘 通하고 部落民이 고루 모이기 쉬운 場所에 位置하고, 主로 여름에 部落民이 더위를 피하고 休息하기 위한 目的으로 使用되는 部落의 共有 共用建物을 가리킨다. ⑵ 茅亭에 關한 名稱은 地方에 따라 서로 다르게 불리워 지고 있다. 卽 "茅亭""詩亭""우산각""農亭""農廳""亭閣""凉廳"等의 普通名詞의 名稱들이 地域別로 使用되고, 또 固有의 稱號가 使用되는 茅亭도 있다. 그러나 各各 틀린 名稱을 使用하기는 하지만, 그것들은 모두 同一性格 同一機能의 建物에 대한 地域間의 呼稱의 差에 不過하다. 大體로 茅亭은 위의 普通名詞中 "茅亭""詩亭""우산각"의 세가지 名稱이 넓은 地域에 걸쳐 使用되고, 그中 "茅亭"이란 呼稱이 가장 널리 頻繁히 使用되고 있다. 그러나 近來에 茅亭의 지붕을 "기와"혹은"함석"으로 改修하고 있어 "茅亭"이란 名稱보다 오히려 扶安郡 一帶에서 呼稱되는 "農亭"이라 고쳐 부르는 것이 妥當할 것으로 생각하였다. ⑶ 모정은 聚落을 形成하고 있는 村落에 建立되어 있는 村落共同體的産物이다. 大部分의 茅亭은 部落共有이며 一部 氏族所有 個人所有 및 契와 같은 團體所有의 茅亭이 있으나, 固有한 意味의 茅亭은 部落共有이었거나 아니거나에 相關없이 部落이 이를 管理하고 部落民이 開放的으로 利用하는 實質的인 部落의 共用 共有建物을 指稱한다. 部落의 共用建物로서의 芽亭은 靑壯年을 中心으로 모든 年齡層이 고루 使用하고, 社會階層으로서는 일하는 農民이 主로 使用하고 있어 芽亭은 일하는 農軍의 休息處로써의 性格이 强하게 浮刻되어 있다. 芽亭은 또한 婦女子는 使用하지 않는 男子의 專用建物로서의 特徵을 갖고 있다. ⑷ 茅亭은 방이 딸려 있지 않은 開放式 亭子를 가르킨다. 一部 방이 附屬되어 있는 茅亭 名稱의 建物이 있기는 하나 그것들은 實質的으로 茅亭이라 할 수 없는 建物을 部落民이 便宜上 "茅亭""우산각" 等으로 呼稱하는 것에 不過한 것 같다. 茅亭의 크기는 部落의 戶數에 따라 決定되는 傾向이 있다. 그러나 大部分의 茅亭은 2 乃至지 3間의 적은 規模의 亭子이었다. 傅洗的 保守的 色彩가 强한 部落의 茅亭은 칸을 막고 또는 層階를 만들어 老少年度을 區別하는 茅亭이 있는 것이다. 茅亭은 大部分 四角形의 建楔樣式이 一般的이지만 個中에는 六角形 八角形의 육모정 팔모정을 찾아 볼 수 있었다. ⑸ 茅亭은 山間地帶보다 平野地帶에 많고 , 海岸 또는 島嶼地代보다 內陸地方에 많다. 茅亭은 水稻作農業의 共同作業에 從事하는 農軍들의 休息場所로써 山間地帶는 田作農業이 中心이 되어 있고 나무그늘과 같은 더위를 避할 수 있는 場所가 많기 때문에 休息場所로서의 茅亭을 따로 建築할 必要性이 적었던 것으로 認定되었고, 다음 島嶼地方에 茅亭이 存入하기 어려운 까닭으로써 첫째 島嶼地方에 밭이 많고 婦女子가 主로 農耕에 從事하며 茅亭이 男子의 專用建物이라는 点과, 둘째 바람이 많고 그러므로써 茅亭의 倒壞의 可能性과 함께 그 管理 및 維持가 어려운 것 等을 指摘할 수 있었다. ⑹ 典型的인 意味의 모정을 忠淸道에서 거의 찾아 볼 수 없고 茅亭이 全羅道에서 支配的으로 發達한 原因으로써 첫째 옛부터 中央政府와의 距離가 먼 全羅道地方은 政府의 統治權의 强化를 爲한 必要性과 部落 스스로의 自衛를 위하여 村落自治의 强化를 要求하였고, 계속하여 村落共同體의 遺制가 强하게 남아 있을 수 있는 蓋然性이 있어 왔고, 그럼으로써 村落의 共有建物인 茅亭이 全羅道에 發生 發達할 수 있는 契機가 恒存하였으리라 생각하였고, 둘째 李朝에 있어 全羅道는 兩班의 數가 比較的 적고 兩班의 後裔들이 農業勞動에 從事함으로써 自負心이 남아 있는 兩班 出身農軍과 衙前의 對立이 激烈하였고, 이와 같은 社會的 環境이 農軍의 自覺을 促求하고, 發言權을 强化하고, 그럼으로써 全羅道地方의 庶民化가 促進되어 庶民的 農軍의 休息場所로서의 茅亭이 發生 發達할 수 있었다고 생각하였다. ⑺ 慶尙道와의 關係에 있어 茅亭의 有無의 關係를 보면, 첫째 慶尙道는 小白山脈의 自然的 要塞에 依하여 社會가 安定되고 또는 바다로부터의 倭寇 및 海賊의 侵犯에 있어서도 全羅道보다 尤甚하지 아니함으로써 社會가 比較的 安定하였을 것이며, 그럼으로써 被支配者로써의 農民의 社會的 地位가 强化될 수 있는 階機를 捕捉하지 못하고 그와 같은 社會的 與件이 茅亭의 發達을 가져오지 못한 까닭이 아닌가 생각하였고, 둘째 茅亭이 반드시 必須的인 것만은 아닌 多少 奢侈的인 것으로써 威風財로써의 性格을 갖는 것이며, 또는 茅亭의 存在가 閑假함을 表現하는 것이라면 經尙道民의 儉素한 生活態度가 茅亭의 建立을 서두르지 않은 까닭이 아니었던가 생각하여 보았고, 셋째 全羅道에서 發生한 茅亭文化가 小白山脈으로 遮斷되어 文化的 交流가 이루어 지지 않은 것이 茅亭이 慶尙道에 普及되지 않은 까닭이라 또한 생각하였다. ⑻ 茅亭의 本源的 原初的 機能으로서 自治的 機能, 産業的 機能, 宗敎的 機能과 敎育 文化的 機能을 들 수 있고, 이와 같은 機能의 重複的인 要求가 茅亭의 發生과 發達을 가져왔을 것이며, 特히 우리나라 水稻作農業의 特徽있는 勞動組織인 "두레"의 運營을 위하여 茅亭은 建立되고 두레組織의 剩餘金이 茅亭 建立의 基金이 되었을 것이라 생각하였고, 또한 村落共同體의 集會所로서의 機能과 亭子나무의 效用이 茅亭 建立의 主要 契機가 되었다고 생각하기도 하였다. ⑼ 現存에 있어 茅亭의 原初的 本源的 機能은 그 內容에 있어 質적인 變化를 가져왔다. 現存의 茅亭의 基本的인 機能은 農軍을 中心으로 部落民의 여름철의 休息과 避暑의 場所이며 特히 "품앗이"의 組織과 "품앗이"꾼의 行動統一에 奇與하는 場所로써 機能하고 있다. 茅亭은 또한 部落民의 團結과 與論의 統一에 도움이 되는 部落의 集會所로써 機能할 뿐 아니라 營農知識의 普及의 場所로써의 機能도 無視할 수 없는 것이다. ⑽ 茅亭은 生活에 便宜를 주는 고마운 施設이기는 하지만 그것 없이 살수 없는 必須的인 것은 아니다. 茅亭의 시원하고 安樂하며 魅力的인 雰圍氣는 農民으로 하여금 오히려 懶怠하게 하고, 消極的 生活態度를 助長한 것이라 볼수 있고, 그것이 韓國農村의 停滯性과 全羅道의 經濟的 貧困을 招來한 一困이 되었다고 생각할수 있고, 또는 茅亭의 社會統制的 機能은 自覺없는 部落民에게 共同體的 束縛을 加하고 個性의 自由로운 伸張을 抑制한 一面을 찾아 볼 수 있다고 생각하였다. ⑾ 農業의 經營組織이 多角的이고, 副業이 發達한 農村에서는 茅亭과 같은 休息의 場所가 크게 必要하지 않을 것이며, 農業의 機械化가 이루어진 社會에 또한 茅亭은 農村의 緊要한 施設이 되지 못할 것이며, 家族과 더불어 生活을 즐기며 家族勞動力으로 大部分의 農作業을 遂行하는 家族勞作的 農業經營이 支配的인 農村에 또한 茅亭은 그 存在 意義가 半減될 것이다. ⑿ 茅亭에 몇가지 弊端이 있다. 그러나 茅亭에 弊端이 있다면 茅亭이 갖는 本來의 機能이나 性格에 弊端이 있는 것이 아니고 茅亭을 利用하는 部落民의 姿勢에 責任이 있는 것이다. 다시 말할 必要도 없이 茅亭의 校用價値는 水稻作農業과 "품앗이" 組織의 共同作業이 存續하는 동안 減少하지 않을 것이다. 茅亭은 水稻作農業社會에 必要한 施設이다. 그러나 團結하지 못한 部落에서는 茅亭은 建立될 수 없고, 또한 維持할 수도 없는 것이다. 茅亭을 갖고 있는 部落은 그것을 자랑으로 생각하고, 茅亭이 없는 部落은 茅亭이 없다는 사실을 수치로 생각하는 傾向이 있는 바 그것은 茅亭이 部落民 團結의 象徵이기 때문이다. ⒀ 茅亭은 過重한 肉體勞動 後의 唯一한 安息處이며, 小農의 宿命的 貧困을 달래어 주는 보금자리이며 樂園이다. 茅亭은 또한 娛樂施設이 적은 農村의 娛樂의 場所로써 寄與하고 있다. 나아가서 茅亭은 與論의 統一과 意見交換의 場所로써 部落民의 民主敎育의 訓練場所가 되고 農村의 民主化에 또한 寄與하고 있는 것이다. ⒁ 茅亭의 建立과 維持에서 結晶된 團結力이 農業의 生産力發展을 위하여 發揮된다면 茅亭은 農業의 近代化를 促進하는데 寄與할수 있고, 部落民은 茅亭에서 農事技術을 배울 수 있을 뿐 아니라 農業近代化의 基礎事業으로써의 耕地整理事業과 農路擴張事業 等의 計劃을 樹立하고 나아가 協同組織의 民主的 運營과 農村生活의 明朗化에 茅亭은 또한 一役을 擔當할 수 있을 것이다. In the Honam area of Korea, there are special types of buildings called Mojong. These buildings serve as resting places after farming labor and as refuges to avoid the heat of summer. The purposes and motives of studying this building are to know: (a) the reason why the Mojongs are located chiefly in the Honam area, while they are rarely found in other provinces; (b) What kind of rural condition makes it necessary to build the Mojong; (c) the original and present functions of the Mojong; (d) the meaning of Mojong to the rural community, etc.. Survey forms were sent to every Myon of Cholla-do to solve the problems mentioned above and to know the distribution of the Mojong. Two thousand and seventy-five forms were received by mail from two hundred and one Myon. With these forms, the researcher could roughly grasp the distribution of Mojong by areas (counties). Among the forms, the researcher selected 383 forms from 5 counties, which the researcher supposes could represent all the Mojong; they were Ik-san, Chong-eup counties in Chollabuk-do, and Chang-song Tam-yang, and Po-song counties in Chollanam-do. Additionally, 62 villages were also surveyed by special forms in order to study the relationship between the social structure of the rural village and the Mojong. The researcher visited many villages and interviewed farmers whenever Problems arose. On the basis of these there research methods, the researcher made the following conclusions; (1) The same building is called by various name in different areas, for example; Mojong, Sijong, Usabgak, Nongjong, and Nongchong. Among these names, Mojong is most widely and commonly used. Therefore it is the name used in this paper. (2) The typical type of Mojong is a building with on room or no walls, with a thatched roof made of rice straw. It is commonly located at the entrance of agricultural villages. This building is used only in the summer. (3) The Mojong is the common property of the village, not of an individual or a clan. The building is equally used by every villager except women. Among the villagers, the main users are the laboring farmers. We can that Mojong is a structure for the working farmers rather than for those of the leisure class of the rural community. (4) Even though Mojongs are chiefly located in the Honam area, they are mostly found in the plain areas rather than in mountaineous arcas, and in inlad areas rather than in island areas. The chief reason, among others, Why the Mojongs are mostly found in the plain and inland arcas is that Mojong is the product of the rice paddy farming society. (5) This is a general tendency for the Mojong to exist and be propagated in the villages where there are common estates owned by the village, for instance, farming land and irrigation facilities for rice paddies, etc. In the light of the above facts, we are able to ascertain that communal villages have persisted more strongly in the Chollado-province than in any other area. This is one of the reasons why there are so many Mojongs in the Cholla-do province, while they are rarely found in other provinces. (6) The Chollado area is far from the Capital. So there was a comparatively small noble class. According to above facts, the lower local offcials in the age of Yi Dynasty exploited the farmers. The descendants of the noble classes were forced to engage in farm labor. The farmers and lower local officials struggled with each other. Influenced by struggling with lower local officials, the farmers of chollado were early conscious of their social status and thus strengthened their positions in their villages. Mojong is the structure for the working farmers, and accordingly could be built in the areas where the farmer's position was relatively strong. This is one of the reasons why there are so many Mojongs in Chollado area. (7) The original functions of the Mojong can be classified as follows: (a) self-governmental, (b) industrial, (c) religious, and (d) cultural or educational. Among these functions, the compulsory rabor exchange organization - the so called "Tu-Re"-of rice paddy farming in Korea provided the funds to build the Mojog out of it's surplus. The organization needs to build the Mojong so that farmers may manage the organization and it's members may meet together and rest before and after farm work. (8) The original functions have changed as the social and economic situation have developed. The most important function of the present Mojong can be poirted out to be the place where villagers can meet and rest, especially the members of the private labor exchange organization, the so called "Pum-asi". Among other functions the Mojong plays a role as the place of education, especially for teaching farming techniques and knowledge. (9) It is belived that the Mojong has both negative and positive influences on the rural community and individual farmers. Some of the villagers spend their time doing nothing but smoking and taking naps all day long in the Mojong during the busy farming season. The Mojong makes the farmers lazy and gives them a passive attitude toward life, because it makes them cool and comfortable. Without Judging its value, good or bad, the farmer is inclined to indulge in such a life. The Mojong would not be necessary; (a) if farming were performed with machines and (b) if farming work could be performed with farmily labor, or (c) if the organization of farm mananement were diversified, and (d) if they have comfortable homes where they can rest. (10) From the view point mentioned above, the Mojong has bad influences on the process of modernization in the rural communities. But the responsibility of these bad influences lies in the hands of frcqucnters of the Mojong, not in the Mojong itself. It seems that the utilization of the Mojong will not decrease as long as rice paddy farming is continued. The Mojong could not be built and maintained in those villages where the villagers do not cooperate. The villagers who have a Mojong feel proud of it, and those who have not feel ashamed, because the Mojong is a symbol of the cooperation and peace of a village. (11) The Mojong is a paradise for the overworked farmers. It serves not only as “farming Center” but also as “the recreation center” of a rural village where there are few recreation facilities. And it plays an important role as the place of training villagers for the democratization of rural communities. (12) If villagers had the same cooperating spirit as they do when they build and maintain the Mojong, it could be said that the Mojong would contribute greatly to the agricuitural modernization by laying out the joint projects of readjusting arable land, of farm road expansion, and of the mechanization of farming.

With a view to regulating proposals for model curricula by establishing the purpose and objectives of education for the department of physical therapy in technical colleges, and to proposing educational objectives and the syllabus on major subjects, we have conducted a comparative analysis of the proposals recommended by the World Confederation for Physical Therapy, those prescribed by the Department of welfare of Japan, model proposals of the Ministry of Education of Korea, and the current curricula and syllabus of local technical colleges, and obtained following conclusions: 1. The purpose of education of physical therapy has been established, which reads "The purpose of the education of physical therapy lies in teaching and studying the special knowledge and theories on the fields of health and medical treatment, practicing the treatment skills, and thus training physical therapists needed to promote the national health" and the objectives to achieve this purpose have been established as follows: (1) To foster such personality and character as needed as a democratic citizen, and to establish firm views of professional ethics. (2) To acquire expert knowledge and treatment skills with which to cope with the requirements of the rapidly growing fields of health and medical treatment. (3) To increase the capabilities to carry out physical therapists' duties effectively as health and medical treatment experts. 2. As to the compilation of curricula, the cultural courses have been divided into required subjects (16 credits) and elective subjects (more than 3 credits) for which more than 19credits(more than 23.75% of the credits required for graduation) must be completed, while the major courses have teen divided into the elementary subjects (12 credits), required subjects (20 credits), and elective subjects .(more than 29 credits), for which more than 61 credits (76.25% of the credits required for graduation). In particular, out of the elective subjects (29 credits), at least 15 credits must be completed for clinical training subjects (See Table 6). 3. The objectives of education by subject and the syllabus on major required subjects and clinical training subjects have been presented. (See Tables 7-13) 4. As results of comparative analysis of the subjects proposed by the World Confederation for Physical Therapy and those prescribed by the Ministry of Welfare of Japan, it is advisable to rearrange them gradually as four-year courses in order to improve special knowledge and treatment skills.

Gas Holdup and mass transfer coefficient were measured and the effect of activity coefficeent and gas velocity on them was studied. Gas holdup increased as the gas velocity increased, and decreased as the concentration of aqueous solutions of NaCl-KCl increased Mass transfer coefficient increased as the gas velocity increased, and decreased as the concentration of aqueous solutions if NaCl-KCl increased. Correlation equation between the gas holdup and mass transfer coefficient, and the various factors is shows a good agreement with experimental values.

齒科用非貴金屬合金의 微細組織과 硬度에 미치는 熱處理의 影響

柳相烈,成在鉉 慶北大學校 齒科大學 1985 慶北齒大論文集 Vol.2 No.1

The purpose of this study was to investigate the effect of heat treatment on microstructure and hardness of Ticonium Premium 100 alloy in different temperature and times for heat treatment. The first group was quenched in water after heating at 550, 700, 850, 1000℃ for 15 minutes: and the second group, after heating for 5, 30, 60, 120 minutes at 700℃. The hardness number of each specimen was obtained using the Rockwell hardnees tester, and the microstructure of each specimen was compared by means of photomi crograph taken by metallurgical microscope. The results were as follows: For a 15-minute duration, the higher the temperature of heat treatment, the higher the hardness of the alloy, but the hardness decreased at 1000℃. At 700℃, the longer the time of heat treatment, the higher the hardness, but the hardness decreased after the 60-minute period of heat treatment. Optimal temperature of heat treatment was 700-850℃ and the optimal time was less than 60 minutes. Microstructure of the heat-treated alloy showed dendritic structure similar to equi-axed structure, but appeared coarse at 1000℃. Microstructure of the alloy heat-treated at different times turned out to be similar to that of the alloy heat-treated at different temperatures, but coarse grains appeared at a 120 minute duration.

유지보수를 위한 프로그램의 복잡도 측정 요소

류성열,이성은,안재홍 崇實大學校 生産技術硏究所 1996 論文集 Vol.26 No.2

70년대 이후 프로그램의 복잡도를 측정하는 척도들이 꾸준하게 연구되어져 프로그램의 크기, 데이터, 제어 등의 부분적 요소를 통하여 프로그램의 복잡도를 측정할 수 있게 됐다. 그러나 대부분이 부분적인 요소를 통한 전체 프로그램의 측정에 초점이 맞추어져 있으며 유지보수의 특성에 관한 부분은 고려되지 않고 있는 실정이다. 프로그램의 유지보수를 위해서는 무엇보다 프로그램의 완벽한 이해가 선행되어야 한다. 따라서 프로그램의 유지보수에 대한 일정이나 비용등을 예측하기 위해서는 대상 프로그램을 이해하는데 얼마나 어려움이 있는가에 대한 척도가 필요하다. 본 논문에서는 유지보수시에 프로그램의 복잡도에 관한 측정에 이용될 수 있는 요소들을 추출하고 그 요소들이 척도로서 활용될수 있는 방안에 대하여 연구하였다. 프로그램의 복잡도 측정 요소로는 기존에 프로그램의 복잡도에 관한 측정에 활용되던 크기, 데이터, 제어요소 보다는 모듈간의 결합관계, 유지보수시 필수적으로 이해가 요구되는 중요 모듈들, 프로그램의 직접적인 이해를 가져올 주석 등을 이용하였다.

한국産 황어의 종묘생산에 관한 연구 1. 産卵習性 및 初期生活史

조재권,오성현,노병율,한경호,성기백,박준택 麗水大學校 産業基術硏究所 1999 産業基術硏究所 論文集 Vol.8 No.-

강원도 양양군에 위치한 남대천과 전라남도 섬진강에 분포하고 있는 황어의 종료생산을 위한 기초자료로 産卵習性과 初期生活史에 관하여 관찰한 결과는 다음과 같다. 황어의 産卵期는 자연상태에서 3∼6月이고, 産卵은 흐르는 하천의 자갈 밑에 하였으며, 受精된 卵은 작은 자갈의 표면에 붙어있었다. 알의 크기는 2.70∼3.20㎜(평균 3.00㎜)로 油球는 없었다. 孵化는 평균 사육수온 10.60℃에서 受精 後 300시간부터 시작되었으며, 312시간만에 완료되었다. 孵化 直後의 仔魚는 전장 6.35∼6.87㎜(평균 10.67㎜)로 난황이 거의 흡수되어 後期仔魚期로 접어들며, 입과 항문이 열려있었다. 孵化 後 7∼9일째 後期仔魚는 전장 11.35∼12.30㎜(평균 11.65㎜)로 등지느러미가 생길 부분이 융기하기 시작하였다. 孵化 後 12∼13일째 개체는 전장 12.65∼13.15㎜(평균 12.80)로 이때부터 Daphnia sp.와 Brachionus plicatilis를 攝餌하였으며, 성장이 다소 빨라졌고, 脊索의 끝부분은 45°위로 굽어져 있었다. 孵化 後 43∼45일째의 개체는 전장이 19.55∼22.85㎜(평균 21.95㎜)로 모든 지느러미 줄기가 정수에 달하여 稚魚期로 이행하였다. 孵化 後 50∼52일째의 稚魚들은 전장이 21.54∼27.35㎜(평균 24.55㎜)로 몸의 형태, 체색 및 옆줄이 완전하게 형성되어 成魚에 닮아 있었다. The spawning behavior and early life history of sea rundace, Tribolodon hakonensis were studied. Spawning of T. hakonensis occurs enmasse on bottoms of stream with a spawning season of March to June. The eggs are attached to the under surface of the gravel. The eggs riped were demersal and adhesive, and their diameter were 2.70∼3.20㎜(mean 3.00㎜). Hatching was started at 300 hours after fertilization at mean water temperature 10.60℃. Newly-hatched larvae were 6.35∼6.87㎜ in total length(TL, Mean 6.65㎜), and mouth and anus were not yet opened. 4∼5 days old larvae transformed to postlarva stage and they were 10.25㎜∼11.15㎜ in TL (mean 10.67㎜). As yolk sac were nearly absorbed, mouth and anus were opened. In 7∼9 days after hatching, total length 11.35∼12.30㎜(mean 11.65㎜). The part of the fin-fold at dorsal fin became high. 12∼13 days old larvae were 12.65∼13.15㎜ in TL(mean 12.80㎜), and they fed Daphnia sp. and Brachionus plicatilis actively. In this time the growth rate slightly increased and tip of notocord was flesed on upward. Aggregate numbers of all fin rays were completed at over 19.55∼22.85㎜ in TL(43∼45 days after hatching), at which time the larvae reached the juvenile stage. 50∼52 days old larvae(21.54∼27.35㎜ in TL) were similar in body from, lateral line and color with adult.

필립스曲線과 安定化政策에 관한 硏究

李在律 啓明大學校 産業經營硏究所 1983 經營經濟 Vol.15 No.1

1. The purpose of this paper is to survey the recent developments in Phillips curve and their relation to the stabilization policy. 2. There has been sever theorectical conflict between the phillips curve doctrine and the natural unemployment rate hypothesis. The latter denies the stability of the Phillips curve and suggests that the long-run Phillips curve is vertical. 3. The policy implication of the Phillips curve doctrine is the need and usefullness of stabilization policy but that of natural unemployment rate hypothesis is the denial of stabilization policy.

農業物市場開放과 農業技術指導

崔在律,金映秀 全南大學校 農漁村開發硏究所 1992 農業科學技術硏究 Vol.27 No.-

The purpose of this study is to discuss the technique guidance for the competition against overseas agricultural products. For the technique guidance, we described the substitution and sellection of the crop items with enable domestic farmers to survive against import liberalization, cost-reducing strategy, and the survive against import liberalization, cost-reducing strategy, and the efficient technique guidance system. For the study, we did literature review and direct interview using questionaries. For the interview, the area was confined to the Chonnam province which was subdivided into 4 categories, suburb, plains, mountains, and in-betweens. The survey was carried out during the period of August 1 through the end of August of 1990. Following are the summary of the annalysis. 1. Excess supply in the world agricultural markets is temporary phenomenon and we should attain the minimum self-support ratio for the emergency. 2. Most farmers show the pessimistic view on the future domestic agriculture because of international pressures on the import liberalization, labor shortage, low domestic agricultural product price, and low income. 3. On the question of the reason we are pressured from the abroad, the answers were the order of manufactured goods export, relatively weak national power, pressure of U.S.A, and failure in the domestic agricultural policy. 4. For the survival of the domestic agriculture, most farmers were answered in the following order by the importance, appropriate government plan, development of agriculture technology, and national consensus on the protection of domestic agriculture. 5. Farmers answered in the order of substitution of crop item, production of high quality goods, and cost reduction when they were asked to list by the impotance the way we can overcome the import liberlization of agriculture products. 6. The reason domestic agriculture is suffering from import liberlization is low productivity and weak price competitiveness. Thus trying to raise the productivity in agriculture and to develop the crop item which has the price competitiveness will be stepping stone for attacking the foreign pressures. 7. The improvement of breed is the major step to win the price competition by the way of technology development in the international market. 8. Highly educated persons are essential for the development of agricultural technology.
