온라인 소비자는 쇼핑 웹사이트에서 특정 제품군이나 브랜드에 속한 제품들을 둘러보고 구매를 진행할 수 있고, 혹은 단순히 넓은 범위의 탐색 반경을 보이며 여러 페이지들을 돌아보다 구매를 진행하지 않고 이탈할 수 있다. 이러한 온라인 소비자의 행동과 구매에 관련된 연구는 꾸준히 진행되어왔으며, 실무에서도 소비자들의 행동 데이터를 바탕으로 한 서비스 및 어플리케이션이 개발되고 있다. 최근에는 빅데이터 기술의 발달로 소비자 개인 단위의 맞춤화 전략 및 추천 시스템이 활용되고 있으며 사용자의 쇼핑 경험을 최적화하기 위한 시도가 진행되고 있다. 하지만 이와 같은 시도에도 온라인 소비자가 실제로 웹사이트를 방문해 제품 구매 단계까지 전환될 확률은 매우 낮은 실정이다. 이는 온라인 소비자들이 단지 제품 구매를 위해 웹사이트를 방문하는 것이 아니라 그들의 쇼핑 동기 및 목적에 따라 웹사이트를 다르게 활용하고 탐색하기 때문이다. 따라서 단지 구매가 진행되는 방문 외에도 다양한 방문 형태를 분석하는 것은 온라인 소비자들의 행동을 이해하는데 중요하다고 할 수 있다. 이러한 관점에서 본 연구에서는 온라인 소비자의 탐색 행동의 다양성과 복잡성을 설명하기 위해 실제 E-commerce 기업의 클릭스트림 데이터를 기반으로 세션 단위의 클러스터링 분석을 진행해 탐색 행동을 유형화하였다. 이를 통해 각 유형별로 상세 단위의 탐색 행동과 구매 여부가 차이가 있음을 확인하였다. 또한 소비자 개인이 여러 방문에 걸친 일련의 탐색 유형에 대한 패턴을 분석하기 위해 순차 패턴 마이닝 기법을 활용하였으며, 같은 기간 내에 제품 구매까지 완료한 소비자와 구매를 진행하지 않은 채 방문만 진행한 소비자들의 탐색패턴에 대한 차이를 확인할 수 있었다. 본 연구의 시사점은 대규모의 클릭스트림 데이터를 활용해 온라인 소비자의 탐색 유형을 분석하고 이에 대한 패턴을 분석해 구매 과정 상의 행동을 데이터 기반으로 설명하였다는 점에 있다. 또한 온라인 소매 기업은 다양한 형태의 탐색 유형에 맞는 마케팅 전략 및 추천을 통해 구매 전환 개선을 시도할 수 있으며, 소비자의 탐색 패턴의 변화를 통해 전략의 효과를 평가할 수 있을 것이다.
글로벌 경영환경 변화로 기술개발과 시장니즈의 불확실성이 커지고 기업 간 상호 경쟁이 심화되면서 개별 기업들의 연구개발 활동에 대한 관심과 요구가 증가하고 있다. 이러한 환경변화에 대응하기 위하여 연구개발 기업들은 설비투자에 더욱 신중을 가하면서 연구개발의 질적인 경쟁력을 제고시키기 위한 수단 중 하나로 연구개발 투자를 강화하고 있다. 결과적으로 설비나 연구개발 투자 요소는 연구개발 기업들의 입장에서는 미래 불확실성을 떠안아야하는 부담이 될 수 밖에 없다. 단지 연구개발 역량을 제고시키기 위한 수단으로 연구개발 투자를 증가시키는 경영 전략은 기업성과측면에서 불확실성이 높은 것이 사실이다. 본 연구에서는 데이터마이닝 기법을 활용하여 기업들의 연구개발 역량에 영향을 주는 특성들을 기술경영능력, 연구개발능력, 그리고 기업분류 속성 관점에서 탐색하고 이러한 개별 요인들이 연구개발 역량의 수준에 따라 나타나는 특성들을 탐색하였다. 이를 위해서 국내 연구개발 기업 전체를 대상으로 증거데이터에 근거해 군집분석과 실험결과를 제시하였다. 상기의 3개 관점마다 세부 평가지표를 각각 7개, 2개, 4개로 구성하여 해당 영역에서의 개별적인 수준을 정량적으로 측정하고자 하였다. 기술경영능력과 연구개발능력의 경우 현행 기술력 평가기관들이 주도적으로 활용하고 있는 소항목 평가지표를 참조하였으며, 이때 정량적으로 자료 확보가능한지 여부를 고려하여 최종적인 세부 평가지표를 새롭게 구성하였다. 기업분류 속성의 경우에는 가장 기본적인 기업 분류 프로파일 정보를 고려하여 구성하였다. 특히 연구개발 역량수준의 동질성 파악을 위해서 기술경영능력과 연구개발능력의 세부평가지표를 활용하여 개별기업별 종합점수를 부여하였으며, 이때 역량수준을 5개의 등급으로 분류하여 군집분석 결과와 비교하였다. 분석된 군집과 역량수준 등급과의 비교평가에 따른 의미를 부여하기 위해서 군집별로 연구개발 역량수준이 높은 경향과 낮은 경향이 존재하는 군집들을 탐색하였다. 이후 해당 군집에서 세부 평가지표에 따른 특징들을 분석하였다. 이와 같은 연구수행 방법을 통해 연구 개발 역량수준이 높은 군집이 2개, 낮은 군집이 1개로 분석되었으며, 나머지 2개의 군집들은 역량수준이 거의 높은 발생 빈도로 유사하게 나타났다. 결과적으로 본 연구에서는 역량수준이 높은 2개 군집과 낮은 1개의 군집들을 대상으로 세부 평가지표에 따른 개별적 특징들을 분석하였다. 본 연구의 결과가 제시하고 있는 시사점은 기술변화 속도와 시장수요의 변화에 효과적으로 대응할 수 있는 전문 경영자의 교체주기가 빠를수록 연구개발 역량 제고에 기여할 가능성이 높다는 점이다. 개인기업의 경우에 법인기업으로의 전환을 통해 연구개발 인력들의 기업에 대한 소속감을 제고시킴으로써 연구개발 역량의 투입강도를 높일 필요가 있으며, 조직적 측면에서도 팀단위의 조직구성을 통해 책임과 권한의 정확성을 제공할 필요가 있다는 점이다. 기술상용화 실적건수나 기술인증건수는 역량제고에 기여하는 경우와 그렇지 않은 경우 모두 발생되고 있어, 경영자 입장에서 연구개발 역량제고를 위한 중요 인자로 검토하는데 한계가 있는 것으로 확인되었다. 마지막으로 실용신안출원의 경험 여부는 연구개발 역량에 중요한 영향을 미치는 요인으로 파악되어, 연구개발 역량 제고를 위해서는 실용신안출원 장려를 위한 동기부여를 제공할 필요성을 확인하였다. 이처럼 본 연구결과는 개별 기업들의 연구개발 역량 제고를 위한 기업 경영전략의 중요한 시사점을 제공할 수 있을 것으로 기대된다.
대한민국 중앙부처, 지방자치단체는 코로나 19가 급속도로 확산하는 팬데믹 상황에서 재난상황 극복을 위해 재난대응에 필요한 정보를 재난문자를 통해 제공하였다. 재난문자는 국민들이 가장 많이 접하는 재난정보 전달수단으로서, 휴대폰에 직접 방송하는 CBS(Cell Broadcast Service) 방식을 채택하고 있어 직접 찾아보는 수고스러움 없이 휴대폰을 통해 쉽게 정보를 접할 수 있다는 장점이 있다. 본 연구는 지난 1년 1개월간(2020년 1월~2021년 1월) 서울특별시에 발송된 재난문자의 특성을 다양한 텍스트마이닝 방법론 등을 통해 도출하고 재난문자에 포함된 다양한 유형의 정보가 국민들의 이동 행태에 어떠한 영향을 미쳤는지를 서울특별시 지역구의 연령별 유동인구의 이동성을 통해 확인하였다. 각 문자에 포함된 주요 단어와 포함된 정보를 분류하는 과정을 거치고 포함된 단어를 기반으로 하는 문서 군집 분석 기법을 적용해 개별 발송 문자를 분석 단위로써 활용할 수 있도록 텍스트 분석을 시행하였다. 이후, 텍스트마이닝을 통해 추출한 재난문자의 특성이 지역별, 연령별 인구이동성에 미친 영향을 규명하였다. 구조화된 모형을 활용하여 재난정보가 인구이동성에 미치는 영향을 기본효과, 누적효과로 구분하여 측정하였다. 지자체가 보유한 재난문자 발송권한으로 인해 재난문자 발송 특성은 지자체별로 상이함을 계량 분석에 활용하였다. 분석 결과 인구이동성에 변화를 유발하는 정보유형은 연령별로 상이함을 확인할 수 있었다. 날짜와 순서에 관련된 정보는 60-70대의 인구이동성을 유의미하게 감소시키는 것을 확인할 수 있었다. 온라인 정보는 20대의 이동성을 감소시켰고, 증상과 관련된 정보는 30대의 인구이동성을 감소시켰다. 한편, 방역 정책 준수를 당부하는 의미를 포함하는 규범적 단어 등은 전 연령의 인구이동성에 유의미한 변화를 불러일으키지 못함을 확인할 수 있었다. 이는 재난대응에 도움이 되는 유의미한 정보들만 재난문자에 포함되어야 함을 의미한다. 한편, 인구이동성에 유의미한 변화를 불러일으키는 정보유형 또한 재난문자가 반복됨에 따라 효과가 상쇄함을 음의 누적효과 추정 결과를 통해 확인할 수 있었다.
우리나라는 근래(近來) 고도경제성장(高度經濟成長)으로 인(因)하여 목재수요(木材需要)가 급증(急增)하고 있으나 국내생산재(國內生産材)가 공급율(供給率)은 수요량(需要量)의 20% 정도(程度)에 지나지 않아 많은 외재(外在)를 도입(導入)하고 있으므로 장래(將來)의 목재(木材) 수요공급(需要供給)의 균형(均衡)을 이룩하기 위하여 강력(强力)한 산림자원(山林資源) 조성사업(造成事業)의 추진(推進)이 요망(要望)된다. 산림자원(山林資源) 조성사업(造成事業)을 추진(推進)하는데 있어서 가장 중요(重要)한 것은 조림의욕(造林意慾)을 높이고 조림사업(造林事業)에 필요(必要)한 산업자본(産業資本)을 산림(山林)에 유치(誘致)하도록 하는 일인데, 이러한 역할(役割)을 할 수 있는 경제적시설(經濟的施設)의 하나가 산림보험제도(山林保險制度)의 실시(實施)인 것이다. 산림보험(山林保險)을 실시(實施)하면 산림재해(山林災害)가 보상(補償)되므로 자본가(資本家)는 안심(安心)하고 조림투자(造林投資)를 할 수 있을 뿐만 아니라 산림(山林)을 담보(擔保)로 한 금융(金融)의 길도 열리어 투자(投資)한 산림(山林)에 환금성(換金性)이 주어지므로 산업자본가(産業資本家)가 산림투자(山林投資)를 회피(回避)하지 않게 되어 산림자원(山林資源) 조성사업(造成事業)이 촉진(促進)될 수 있다. 이러한 관점(觀點)에서 외국(外國)에서는 19세기말(世紀末)부터 산림보험제도(山林保險制度)가 실시(實施)되기 시작(始作)하여 주요(主要) 임업선진국(林業先進國)에서는 모두 산림보험(山林保險)을 실시(實施)하고 있는 것이다. 산림보험(山林保險)을 실시(實施)하는데 있어서 가장 중요(重要)한 것은 장기간(長期間)에 걸친 산림재해(山林災害)의 통계자료(統計資料)를 정확(正確)히 조사(調査)하는 일과 그 나라의 여건(與件)에 맞는 산림보험제도(山林保險制度)를 창설(創設)하는 일이다. 과거(過去) 10년간(年間)(1961~1970)의 년평균(年平均) 산림재해상황(山林災害狀況)을 조사(調査)한 결과(結果)는 산림화재(山林火災)가 9,000여정보(餘町步), 곤충피해(昆蟲被害)가 570,000정보(町步), 병균피해(病菌被害)가 694정보(町步)로 나타났다. 특(特)히 그중 외국(外國)의 산림보험(山林保險)에서 재해보상(災害補償) 대상(對象)의 으뜸이 되고 있는 산림화재(山林火災) 피해상황(被害狀況)을 과거(過去) 18년간(年間)(1953~1970)에 걸쳐서 조사(調査)한 결과(結果)에 의하면 산화면적(山火面積) 위험율(危險率)이
At the initial stage of Internet advertising, banner advertising came into fashion. As the Internet developed into a central part of daily lives and the competition in the on-line advertising market was getting fierce, there was not enough space for banner advertising, which rushed to portal sites only. All these factors was responsible for an upsurge in advertising prices. Consequently, the high-cost and low-efficiency problems with banner advertising were raised, which led to an emergence of keyword advertising as a new type of Internet advertising to replace its predecessor. In the beginning of 2000s, when Internet advertising came to be activated, display advertisement including banner advertising dominated the Net. However, display advertising showed signs of gradual decline, and registered minus growth in the year 2009, whereas keyword advertising showed rapid growth and started to outdo display advertising as of the year 2005. Keyword advertising refers to the advertising technique that exposes relevant advertisements on the top of research sites when one searches for a keyword. Instead of exposing advertisements to unspecified individuals like banner advertising, keyword advertising, or targeted advertising technique, shows advertisements only when customers search for a desired keyword so that only highly prospective customers are given a chance to see them. In this context, it is also referred to as search advertising. It is regarded as more aggressive advertising with a high hit rate than previous advertising in that, instead of the seller discovering customers and running an advertisement for them like TV, radios or banner advertising, it exposes advertisements to visiting customers. Keyword advertising makes it possible for a company to seek publicity on line simply by making use of a single word and to achieve a maximum of efficiency at a minimum cost. The strong point of keyword advertising is that customers are allowed to directly contact the products in question through its more efficient advertising when compared to the advertisements of mass media such as TV and radio, etc. The weak point of keyword advertising is that a company should have its advertisement registered on each and every portal site and finds it hard to exercise substantial supervision over its advertisement, there being a possibility of its advertising expenses exceeding its profits. Keyword advertising severs as the most appropriate methods of advertising for the sales and publicity of small and medium enterprises which are in need of a maximum of advertising effect at a low advertising cost. At present, keyword advertising is divided into CPC advertising and CPM advertising. The former is known as the most efficient technique, which is also referred to as advertising based on the meter rate system; A company is supposed to pay for the number of clicks on a searched keyword which users have searched. This is representatively adopted by Overture, Google's Adwords, Naver's Clickchoice, and Daum's Clicks, etc. CPM advertising is dependent upon the flat rate payment system, making a company pay for its advertisement on the basis of the number of exposure, not on the basis of the number of clicks. This method fixes a price for advertisement on the basis of 1,000-time exposure, and is mainly adopted by Naver's Timechoice, Daum's Speciallink, and Nate's Speedup, etc, At present, the CPC method is most frequently adopted. The weak point of the CPC method is that advertising cost can rise through constant clicks from the same IP. If a company makes good use of strategies for maximizing the strong points of keyword advertising and complementing its weak points, it is highly likely to turn its visitors into prospective customers. Accordingly, an advertiser should make an analysis of customers' behavior and approach them in a variety of ways, trying hard to find out what they want. With this in mind, her or she has to put multiple keywords into use when running for ads. When he or she first runs an ad, he or she should first give priority to which keyword to select. The advertiser should consider how many individuals using a search engine will click the keyword in question and how much money he or she has to pay for the advertisement. As the popular keywords that the users of search engines are frequently using are expensive in terms of a unit cost per click, the advertisers without much money for advertising at the initial phrase should pay attention to detailed keywords suitable to their budget. Detailed keywords are also referred to as peripheral keywords or extension keywords, which can be called a combination of major keywords. Most keywords are in the form of texts. The biggest strong point of text-based advertising is that it looks like search results, causing little antipathy to it. But it fails to attract much attention because of the fact that most keyword advertising is in the form of texts. Image-embedded advertising is easy to notice due to images, but it is exposed on the lower part of a web page and regarded as an advertisement, which leads to a low click through rate. However, its strong point is that its prices are lower than those of text-based advertising. If a company owns a logo or a product that is easy enough for people to recognize, the company is well advised to make good use of image-embedded advertising so as to attract Internet users' attention. Advertisers should make an analysis of their logos and examine customers' responses based on the events of sites in question and the composition of products as a vehicle for monitoring their behavior in detail. Besides, keyword advertising allows them to analyze the advertising effects of exposed keywords through the analysis of logos. The logo analysis refers to a close analysis of the current situation of a site by making an analysis of information about visitors on the basis of the analysis of the number of visitors and page view, and that of cookie values. It is in the log files generated through each Web server that a user's IP, used pages, the time when he or she uses it, and cookie values are stored. The log files contain a huge amount of data. As it is almost impossible to make a direct analysis of these log files, one is supposed to make an analysis of them by using solutions for a log analysis. The generic information that can be extracted from tools for each logo analysis includes the number of viewing the total pages, the number of average page view per day, the number of basic page view, the number of page view per visit, the total number of hits, the number of average hits per day, the number of hits per visit, the number of visits, the number of average visits per day, the net number of visitors, average visitors per day, one-time visitors, visitors who have come more than twice, and average using hours, etc. These sites are deemed to be useful for utilizing data for the analysis of the situation and current status of rival companies as well as benchmarking. As keyword advertising exposes advertisements exclusively on search-result pages, competition among advertisers attempting to preoccupy popular keywords is very fierce. Some portal sites keep on giving priority to the existing advertisers, whereas others provide chances to purchase keywords in question to all the advertisers after the advertising contract is over. If an advertiser tries to rely on keywords sensitive to seasons and timeliness in case of sites providing priority to the established advertisers, he or she may as well make a purchase of a vacant place for advertising lest he or she should miss appropriate timing for advertising. However, Naver doesn't provide priority to the existing advertisers as far as all the keyword advertisements are concerned. In this case, one can preoccupy keywords if he or she enters into a contract after confirming the contract period for advertising. This study is designed to take a look at marketing for keyword advertising and to present effective strategies for keyword advertising marketing. At present, the Korean CPC advertising market is virtually monopolized by Overture. Its strong points are that Overture is based on the CPC charging model and that advertisements are registered on the top of the most representative portal sites in Korea. These advantages serve as the most appropriate medium for small and medium enterprises to use. However, the CPC method of Overture has its weak points, too. That is, the CPC method is not the only perfect advertising model among the search advertisements in the on-line market. So it is absolutely necessary that small and medium enterprises including independent shopping malls should complement the weaknesses of the CPC method and make good use of strategies for maximizing its strengths so as to increase their sales and to create a point of contact with customers.

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.
