  • Historical interest in China in 1930s has been mostly focused on political characteristic of the National Government(國民政府) which was established by the KMT(中國國民黨) as a result of national unification. It is certain that China had a chance to construct a modern country by the establishment of the very unified revolutionary government. But, it was the time of expanding national crises that threatened the existence of the country such as the Manchurian Incident and the Chinese-Japanese War as well as the chaos of the domestic situation, too. So it has a good reason to examine the characteristic and pattern of the response of the political powers of those days. But, as shown in the recent studies, the manifestation method of political power by the revolutionary regime catches our attention through the understanding of internal operating system. Though this writing started from the fact that the Nationalist Government executed the administrative reform which aimed at "administrative efficiency" in the middle of 1930s, but it put stress on the seriousness of the problem and its solution rather than political background or results. "Committee on Administrative Efficiency(行政效率委員會)", the center of administrative reform movement which was established in 1934, examined the plan to execute the reform through legislation by the Executive Council(行政院) on the basis of the results of relevant studies. They claimed that the construction of a modern country should be performed by not political revolution anymore but by gradual improvement and daily reform, and that the operation of the government should become modern, scientific and efficient. There were many fields of administrative reform subjects, but especially, the field of records and archives adminstration(文書檔案行政) was studied intensively from the initial stage because that subject had already been discussed intensively. They recognized that records and archives were the basic tool of work performance and general activity but an inefficient field in spite of many input staff members, and most of all, archival reform bring about less conflicts than the fields of finance, organization and personnel. When it comes to the field of records adminstration, the key subjects that records should be written simply, the process of record treatment should be clear and the delay of that should be prevented were already presented in a records administrative meeting in 1922. That is, the unified law about record management was not established, so each government organization followed a conventional custom or performed independent improvement. It was through the other records administrative workshop of the Nationalist Government in 1933 when the new trend was appeared as the unified system improvement. They decided to unify the format of official records, to use marker and section, to unify the registration of receipt records and dispatch records and to strengthen the examination of records treatment. But, the method of records treatment was not unified yet, so the key point of records administrative reform was to establish a unified and standard record management system for preventing repetition by simplifying the treatment procedure and for intensive treatment by exclusive organizations. From the foundation of the Republic of China to 1930s, there was not big change in the field of archives administration, and archives management methods were prescribed differently even in the same section as well as same department. Therefore, the point at issue was to centralize scattered management systems that were performed in each section, to establish unified standard about filing and retention period allowance and to improve searching system through classification and proper number allowance. Especially, the problem was that each number system and classification system bring about different result due to dual operation of record registration and archives registration, and that strict management through mutual contrast, searching and application are impossible. Besides, various problems such as filing tools, arrangement method, preservation facilities & equipment, lending service and use method were raised also. In the process this study for the system improvement of records and archives management, they recognized that records and archives are the identical thing and reached to create a successive management method of records and archives called "Records and Archives Chain Management Method(文書檔案連鎖法)" as a potential alternative. Several principles that records and archives management should be performed unitedly in each organization by the general record recipient section and the general archives section under the principle of task centralization, a consistent classification system should be used by classification method decided in advance according to organizational constitution and work functions and an identical number system should be used in the process of record management stage and archive management stage by using a card-type register were established. Though, this "Records and Archives Chain Management Method" was developed to the stage of test application in several organizations, but it was not adopted as a regular system and discontinued. That was because the administrative reform of the Nationalist Government was discontinued by the outbreak of the Chinese-Japanese War. Even though the administrative reform in the middle of 1930s didn't produce practical results but merely an experimentation, it was verified that the reform against tradition and custom conducted by the Nationalist Government that aimed for the construction of a modern country was not only a field of politics, but on the other hand, the weak basis of the government operation became the obstacle to the realization of the political power of the revolutionary regime. Though the subject of records and archives administrative reform was postponed to the future, it should be understood that the consciousness of modern records and archives administration and overall studies began through this examination of administrative reform.

  • Much has teed changed in the field of hospital administration in the It wake of the rapid development of sciences, techniques ana systematic hospital management. However, we still have a long way to go in organization, in the quality of hospital employees and hospital equipment and facilities, and in financial support in order to achieve proper hospital management. The above factors greatly effect the ability of hospitals to fulfill their obligation in patient care and nursing services. The purpose of this study is to determine the optimal methods of standardization and quality nursing so as to improve present nursing services through investigations and analyses of various problems concerning nursing administration. This study has been undertaken during the six month period from October 1971 to March 1972. The 41 comprehensive hospitals have been selected iron amongst the 139 in the whole country. These have been categorized according-to the specific purposes of their establishment, such as 7 university hospitals, 18 national or public hospitals, 12 religious hospitals and 4 enterprise ones. The following conclusions have been acquired thus far from information obtained through interviews with nursing directors who are in charge of the nursing administration in each hospital, and further investigations concerning the purposes of establishment, the organization, personnel arrangements, working conditions, practices of service, and budgets of the nursing service department. 1. The nursing administration along with its activities in this country has been uncritical1y adopted from that of the developed countries. It is necessary for us to re-establish a new medical and nursing system which is adequate for our social environments through continuous study and research. 2. The survey shows that the 7 university hospitals were chiefly concerned with education, medical care and research; the 18 national or public hospitals with medical care, public health and charity work; the 2 religious hospitals with medical care, charity and missionary works; and the 4 enterprise hospitals with public health, medical care and charity works. In general, the main purposes of the hospitals were those of charity organizations in the pursuit of medical care, education and public benefits. 3. The survey shows that in general hospital facilities rate 64 per cent and medical care 60 per-cent against a 100 per cent optimum basis in accordance with the medical treatment law and approved criteria for training hospitals. In these respects, university hospitals have achieved the highest standards, followed by religious ones, enterprise ones, and national or public ones in that order. 4. The ages of nursing directors range from 30 to 50. The level of education achieved by most of the directors is that of graduation from a nursing technical high school and a three year nursing junior college; a very few have graduated from college or have taken graduate courses. 5. As for the career tenure of nurses in the hospitals: one-third of the nurses, or 38 per cent, have worked less than one year; those in the category of one year to two represent 24 pet cent. This means that a total of 62 per cent of the career nurses have been practicing their profession for less than two years. Career nurses with over 5 years experience number only 16 per cent: therefore the efficiency of nursing services has been rated very low. 6. As for the standard of education of the nurses: 62 per cent of them have taken a three year course of nursing in junior colleges, and 22 per cent in nursing technical high schools. College graduate nurses come up to only 15 per cent; and those with graduate course only 0.4 per cent. This indicates that most of the nurses are front nursing technical high schools and three year nursing junior colleges. Accordingly, it is advisable that nursing services be divided according to their functions, such as professional, technical nurses and nurse's aides. 7. The survey also shows that the purpose of nursing service administration in the hospitals has been regulated in writing in 74 per cent of the hospitals and not regulated in writing in 26 per cent of the hospitals. The general purposes of nursing are as follows: patient care, assistance in medical care and education. The main purpose of these nursing services is to establish proper operational and personnel management which focus on in-service education. 8. The nursing service departments belong to the medical departments in almost 60 per cent of the hospitals. Even though the nursing service department is formally separated, about 24 per cent of the hospitals regard it as a functional unit in the medical department. Only 5 per cent of the hospitals keep the department as a separate one. To the contrary, approximately 12 per cent of the hospitals have not established a nursing service department at all but surbodinate it to the other department. In this respect, it is required that a new hospital organization be made to acknowledge the independent function of the nursing department. In 76 per cent of the hospitals they have advisory committees under the nursing department, such as a dormitory self·regulating committee, an in-service education committee and a nursing procedure and policy committee. 9. Personnel arrangement and working conditions of nurses 1) The ratio of nurses to patients is as follows: In university hospitals, 1 to 2.9 for hospitalized patients and 1 to 4.0 for out-patients; in religious hospitals, 1 to 2.3 for hospitalized patients and 1 to 5.4 for out-patients. Grouped together this indicates that one nurse covers 2.2 hospitalized patients and 4.3 out-patients on a daily basis. The current medical treatment law stipulates that one nurse should care for 2.5 hospitalized patients or 30.0 out-patients. Therefore the statistics indicate that nursing services are being peformed with an insufficient number of nurses to cover out-patients. The current law concerns the minimum number of nurses and disregards the required number of nurses for operation rooms, recovery rooms, delivery rooms, new-born baby rooms, central supply rooms and emergency rooms. Accordingly, tile medical treatment law has been requested to be amended. 2) The ratio of doctors to nurses: In university hospitals, the ratio is 1 to 1.1; in national of public hospitals, 1 to 0.8; in religious hospitals 1 to 0.5; and in private hospitals 1 to 0.7. The average ratio is 1 to 0.8; generally the ideal ratio is 3 to 1. Since the number of doctors working in hospitals has been recently increasing, the nursing services have consequently teen overloaded, sacrificing the services to the patients. 3) The ratio of nurses to clerical staff is 1 to 0.4. However, the ideal ratio is 5 to 1, that is, 1 to 0.2. This means that clerical personnel far outnumber the nursing staff. 4) The ratio of nurses to nurse's-aides; The average 2.5 to 1 indicates that most of the nursing service are delegated to nurse's-aides owing to the shortage of registered nurses. This is the main cause of the deterioration in the quality of nursing services. It is a real problem in the guest for better nursing services that certain hospitals employ a disproportionate number of nurse's-aides in order to meet financial requirements. 5) As for the working conditions, most of hospitals employ a three-shift day with 8 hours of duty each. However, certain hospitals still use two shifts a day. 6) As for the working environment, most of the hospitals lack welfare and hygienic facilities. 7) The salary basis is the highest in the private university hospitals, with enterprise hospitals next and religious hospitals and national or public ones lowest. 8) Method of employment is made through paper screening, and further that the appointment of nurses is conditional upon the favorable opinion of the nursing directors. 9) The unemployment ratio for one year in 1971 averaged 29 per cent. The reasons for unemployment indicate that the highest is because of marriage up to 40 per cent, and next is because of overseas employment. This high unemployment ratio further causes the deterioration of efficiency in nursing services and supplementary activities. The hospital authorities concerned should take this matter into a jeep consideration in order to reduce unemployment. 10) The importance of in-service education is well recognized and established. 1% has been noted that on the-job nurses. training has been most active, with nursing directors taking charge of the orientation programs of newly employed nurses. However, it is most necessary that a comprehensive study be made of instructors, contents and methods of education with a separate section for in-service education. 10. Nursing services'activities 1) Division of services and job descriptions are urgently required. 81 per rent of the hospitals keep written regulations of services in accordance with nursing service manuals. 19 per cent of the hospitals do not keep written regulations. Most of hospitals delegate to the nursing directors or certain supervisors the power of stipulating service regulations. In 21 per cent of the total hospitals they have policy committees, standardization committees and advisory committees to proceed with the stipulation of regulations. 2) Approximately 81 per cent of the hospitals have service channels in which directors, supervisors, head nurses and staff nurses perform their appropriate services according to the service plans and make up the service reports. In approximately 19 per cent of the hospitals the staff perform their nursing services without utilizing the above channels. 3) In the performance of nursing services, a ward manual is considered the most important one to be utilized in about 32 percent of hospitals. 25 per cent of hospitals indicate they use a kardex; 17 per cent use ward-rounding, and others take advantage of work sheets or coordination with other departments through conferences. 4) In about 78 per cent of hospitals they have records which indicate the status of personnel, and in 22 per cent they have not. 5) It has been advised that morale among nurses may be increased, ensuring more efficient services, by their being able to exchange opinions and views with each other. 6) The satisfactory performance of nursing services rely on the following factors to the degree indicated: approximately 32 per cent to the systematic nursing activities and services; 27 per cent to the head nurses ability for nursing diagnosis; 22 per cent to an effective supervisory system; 16 per cent to the hospital facilities and proper supply, and 3 per cent to effective in·service education. This means that nurses, supervisors, head nurses and directors play the most important roles in the performance of nursing services. 11. About 87 per cent of the hospitals do not have separate budgets for their nursing departments, and only 13 per cent of the hospitals have separate budgets. It is recommended that the planning and execution of the nursing administration be delegated to the pertinent administrators in order to bring about improved proved performances and activities in nursing services.

  • Recently the request of the patients to participate in the medical courses has been expanding due to the elevated sense of right on the people's health, merchandised medical treatment by mass supply, human right declaration of the patients, generalized medical informations by the mass media and the change of human relation between the medical personnels and the patients. Under these phenomena the patients have been in the thought of solving such accidents only by regulation of the laws which they think to be all powerful, Such trends are same in the area of nursing service. Also today the accident by the nurses have been increasing by the area of the nurses having been expanded and their independent roles having been increased. Such nursing accidents are the important subject which the professional occupation of the nurse has been facing but legal protective capability of the nurses has been very weak. Therefore this study has examined the degree of the experience of the nursing accident that happens in the clinical nursing scenes in the general hospital to provide the basic materials for the protection and the counter measures of the nursing accident. The following is the conclusion based by the above examination. 1) The experience degree of the whole nursing accidents has been appeared as 1.90 in average. And the degree according to service area has been 1.77 in the area of supervising management of patients, 1.54 in the area of the same management of patients by head-nurses, 1.84 in the area of doctors' treatment performances, 14 in the enforcement and education areas of the nursing technology, 2.04 in the area of observing patients and judgement and 2.07 in the area of nursing records and maintaining confidentials. Accordingly there has been higher degree of accidental experiences in the independent service areas of the patients than in the dependent ones directed by the doctors. 2) The perception of the nurses showed that the cause of the nursing accident has been due to the heavy work of the nurses with the 60.4% of the response rate, the highest rate. They report the accident to the head nurse first by 2/3 nurses after accident. And the hour of the accident has been frequently happened regardless of service hours with 48.1% in response rate, the highest rate, and the nursing accident happens in the night more than the daytime with the rate of 37.5% at night while 14. 4% daytime. 3) The nurses are in the perception that the patients are responsible for the accident with 48.2% response rate while 43.9% rate in response showed that it has been caused by many people. They are in the perception that 41.7% when the nursing power was lacking, 46.7% lower recognition of actual state about indivitual patient in the section of technical speciality and 35.8% when the patients were not cooperative and 37.8% when the wards were dirty and in disorder. 4) the attitude of the patients after the various nursing accidents has been violent words in 72.7%, violence in 17.4% and 3.9% in attending the court by the sue of the patient's side(18 nurses). 5) The action of the hospital has been : requesting the submission of the story of the accident in 22.8%, the report of the accidents in 14.4%, thus the written statement disposal was most, 4.5% was the transfer to the other departments when the accident was larger or the patients' guardians protested strongly and 0.6% of the dismissals of the nurses. 6) In regard to the responsiblity of the nurse accidents, 78.9% was the highest rate of supplying the nursing manpowers, 48.4% of mutual cooperation of the medical personnels, 37.2% of strengthening the education for the nurses and hospital facilities reformation in 32.7%. 7) The review of relation between the general characters of the object of the study and the degree of experience of nursing accidents showed the significant differences in ages (F=4.04, p=0.000).

  • Nowerdays, the increase of traffic accidents and old age population make the Femoral Neck Fracture(FNF) patients increase. By the improvement of education and standard of living the patients demand better medical service than before. This study is designed to give practical help for the FNF patients by observing their hospital life and establish practical nursing strategies for the FNF patients. For these purposes the Ethnographic Participant Observation was adopted. By this study is focused on the hospital life patient's view. For this end, the field study adopted orthopedic ward in the C University Hospital with 400 beds in Seoul. The object patients of the study were twelve patients. The patients experienced five stages : Embarrassment, Conflict, Stability, Independent, and Extension Stage. The findings and prepared nursing strategies are stated as follows. First, in the Embarrassment Stage they suffered embarrassment, anxiety, pain, they could not do ordinary things. The patients who accidental fractures had anxiety from unfamiliar tests and from hospitalization itself. They lamented that they could not ordinary things, and do nothing but obeying the hospital, and endure the pain. They recognized the changed environment and resigned themselves to life in the ward. In this stage, full openness by the nurses is needed. Second, the attribute of the Conflict Stage were conflict, fear, curiosity, belief, reflection. When they sign the consentment form, they experience conflicts about the possibility of complication, fear of recovery from anesthesia, curiosity about the operation procedure, post - operation state, reflection on their past life, and promise to care for their family members after discharge and keep their religious life faithfully. And they accepted the operation depending on God, believing in modern medicine, and the surgeon. Asking for their changed informations, they expected positive results from the operation. In this stage, an empathic attitude by the nurses is needed. Third, the attribute of the Stability Stage were relief, gratitude, difficulty with excretion, and pain. When they awoke from anesthesia, they felt relief because of a the end of the operation, but they experienced extreme pain, difficulty of excretion in bed. They accepted the changed environment and expected recovery. In this stage, support by the nurses is needed. Fourth, the attributes of the Independence Stage were freedom, exercise, nurturing, anxiety, and discomfort. When they ambulated and exercised, they experienced freedom. They showed exhibited weakness of the digestive organs and discomfort hospital's space, structure, and facilities, the delay of medical certificate issue the lack of prompt response by the medical agents. They ate nurturious food and felt anxiety on the end of hospital life and returning to their ordinary life. They showed the independence of overcoming their environment by increasing exercise and expected their discharges. In this stage, respect by the nurses is needed for the patients to, overcome their environment and prepare for their independence. Fifth, the attributes of the Extension Stage were pessimism, isolation, dissatisfaction, and pain. Accompanied injury and old age made their ward life extend to over seven weeks. They exhibited weariness, melancholy, skeptisis, general pessimistic feeling, and desperation caused by their isolated life. They experienced the digestive discomfort caused by the prolonged medication and psycological pain caused by long-time hospitalization. As a, result, their dissatisfaction on the human, physical, and systematic environments had been increased. They acquired critical power and sought for something to do spending their time. They expected vaguely about the returning of their ordinary life. In this stage, counseling is needed by the nurse to overcome positively their psychological, social, and physical problems. The process of the FNF patient's ward life starts from the dependent state, when they are hospitalized, and gradually progresses to self-fulfillment in order to keep independent life. As a result, the FNF patients showed "Response in Challenge" or "Adaptation in Conflict" through their experiences of social, physical, and psychological difficulties.

  • 한국 유통산업이 무한 경쟁에 박차를 가하고 있다. 저성장시대를 맞으면서 각 소매업태간의 경쟁 중에 힘이 약한 자는 생존의 문제에 직결되기 마련이다. 근 수년간 대형할인마트가 매년 꾸준한 성장세를 보여 왔다. 그러나 점포수의 포화, 신규부지 확보의 어려움, 불경기로 인한 소비자의 소비행태 변화 등의 이유로 고객밀착형의 새로운 업태의 진출을 모색하게 되었다. 이에 따라 최근 대기업은 대기업 계열 기업형 슈퍼마켓을 만들었고 전통시장 상권에 따라서 대형유통업체의 막강한 바잉파워를 배경으로 SSM이라는 신업태에 역량을 집중하여 전국적 다점포화를 공격적으로 전개해 왔다. 이러한 출점은 지역사회에 기반을 둔 중소유통 그중에서도 일정규모이상의 개인 슈퍼마켓에 직격탄을 날리고 있다. 개인 슈퍼마켓과 소매상인들은 낡은 판매시설과 기존 운영방식으로 인하여 사업의 경쟁력을 잃어가고 있다. 최근 대기업 계열 기업형 슈퍼마켓의 전통시장 상권에 대하여 언론, 학계, 업계 등에서 매우 논란이 많고 이와 관련된 세미나와 공청회도 많이 열리고 있다. 이에 따른 규제로 출점 속도를 늦출 수는 있으나 결정적 대안은 아닐 것이다. 기업형 SSM이 최근 급증하는 이유는 정체로 접어든 오프라인 할인마트 업체들의 새로운 성장분야를 찾기 위한 목적이 크다. 이미 대형할인마트 형태로는 전국 대부분의 지리적 요지에 다 입점해 있어 포화상태에 이르렀기 때문이다. 할인마트로 커버하지 못하는 소규모 상권을 공략하기 위해서는 SSM 형태의 사업이 확대가 절실하다. 이에 반하여 개인 슈퍼마켓은 경쟁력을 잃어 간다. 개인 슈퍼마켓의 취약점은 가격적인 면에서 규모의 경제를 실현 할 수 없기에 소량으로 판매 물건을 구입하고 있으며, 이로 인해 구입단가 할인이 어려운 상황이다. 또한 조직화 및 협업화가 부진하고 상인교육이 활성화 되지 못한 부분이 서비스로 직결되기 때문에 힘든 상황이다. 이에 따른 해결책으로 농산물, 청과, 공산품 등의 전문점을 만들어 상권을 형성하는 방법이 있다. 둘째, 개인 슈퍼마켓의 가맹점 가입 추진을 통한 조직화. 협업화를 촉진하여 규모의 경제를 취득함과 동시에 정부에 제안 할 수 있는 하나의 기업형태가 되는 것이다. 셋째, 중소상인 교육의 활성화로 서비스 의식을 고취하고 좋은 서비스로 소비자를 모아야 한다는 점이다. 또한 SSM에서 할 수 없는 심리적 점포 운영으로 소비자의 심리를 자극 하는 것도 하나의 방법이 될 것이다. 일본에는 이미 전일식 체인으로 소상공인들의 생활이 한편 나아졌다. 이에 개인슈퍼마켓을 비롯한 중소유통점들의 취약 부분을 알아보고 경쟁력 강화 방안에 대해 자세히 제안하고자 한다.

  • 중국이 경제대국으로의 성장한데 이어 한국의 제1위 교역국으로서 2015년 6월 1일 한 중 FTA 정식 서명이 이루어짐에 따라 한 중간 교역 규모 증가가 예상된다. 본 연구에서는 한 중간 FTA 체결에 따라 더욱 증가할 수 있는 수출입 물동량과 한 중간 카페리노선 활용도를 제고하고자 하였다. 따라서 현재 운항중인 카페리선사 및 컨테이너 정기선사를 이용 중인 화주 및 포워더를 대상으로 카페리선사의 발전전략이라는 목적을 전제 하에 두 개의 설문조사를 실시하였다. 먼저 한 중 카페리선사 및 정기선사를 이용하는 화주 및 포워더를 대상으로 선사 선택요인에 대한 중요도 우선순위를 도출하고자 하였다. 이를 위해 카페리 및 정기선사 경쟁력 강화방안에 대한 선행연구를 분석하여 변수의 조작적 정의를 주요인은 신속성, 경제성 그리고 안전성으로 구분하고 다시 신속성에 관한 세부요인을 한 중 해상항로를 운항하는 선박 운항시간과, 항만에서 화물을 싣고 내리는 하역시간, 그리고 관세법에 따른 절차를 이행하여 물품을 수출, 수입, 반송하는 통관시간으로 구분하였고, 경제성 요인에 관한 세부요인은 수도권항만에서 중국으로 운항하는 해상운임부분과 항만에서 선박으로부터 화물을 싣고 내리는 하역비용, 그리고 항만 하역 후에 육상운송으로 화주에게 화물을 배송하는 내륙 연계 운임 비용으로 구분하였다. 마지막으로 안정성에 관한 세부요인으로는 카페리선과 정기선사 운항시 선박의 흔들림으로 인한 화물의 파손율과 화물의 흔들림을 최소화하기 위한 라싱(Lashing) 및 쇼어링(Shoring) 등의 고박장치 시설, 그리고 운행표를 미리 작성하여 이것에 따라 선박을 운항할 때 출발시간 및 도착시간이 스케줄에 따라 정해진 시간에 이루어지는가에 대한 운항의 정시성으로 세부요인을 구분하였다. 계층분석법(AHP)을 활용한 주요인에 대한 카페리 및 정기선사 선택요인의 중요도 우선순위 분석결과, 카페리 선사 물류서비스 이용자인 화주그룹은 신속성 0.549, 안정성 0.309, 경제성 0.142로, 항목간 중요도 차이가 크게 나타났으나, 물류서비스 공급자인 포워더그룹은 신속성 0.350, 안정성 0.348, 경제성 0.302로 중요도 차이가 크게 나타나지 않았다. 반면 정기선사를 이용하고 있는 화주 및 포워더 그룹은 카페리 선사를 이용하고 있는 그룹과 달리 경제성>안정성>신속성 순으로 중요하게 생각하고 있음을 알 수 있다.
