Purpose: The purpose of this study is to assess the operational status and level of understanding among IRB and HRPP staffs at a hospital or a research institute to the HRPP guideline set by the Ministry of Food and Drug Safety (MFDS) and to provide recommendations. Methods: Online survey was distributed among members of Korean Association of IRB (KAIRB) through each IRB office. The result was separated according to topic and descriptive statistics was used for analysis. Result: Survey notification was sent out to 176 institutions and 65 (37.1%) institutions answered the survey by online. Of 65 institutions that answered the survey; 83.1% was hospital, 12.3% was university, 3.1% was medical college, 1.5% was research institution. 23 institutions (25.4%) established independent HRPP offices and 39 institutions (60.0%) did not. 12 institutions (18.5%) had separate IRB and HRPP heads, 21 (32.3%) institutions separated business reporting procedure and person in charge, 12 institutions separated the responsibility of IRB and HRPP among staff, and 45 institutions (69.2%) had audit & non-compliance managers. When asked about the most important basic task for HRPP, 23% answered self-audit. And according to 43.52%, self-audit was also the most by both institutions that operated HRPP and institutions that did not. When basic task performance status was analyzed, on average, the institutions that operated HRPP was 14% higher than institutions that only operated IRB. 9 (13.8%) institutions were evaluated and obtained HRPP accreditation from MFDS and the most common reason for obtaining the accreditation was to be selected as Institution for the education of persons conducting clinical trial (6 institutions). The most common reason for not obtaining HRPP accreditation was because of insufficient staff and limited capacity of the institution (28%). Institutions with and without a plan to be HRPP accredited by MFDS were 20 (37.7%) each. 34 institutions (52.3%) answered HRPP evaluation method and accreditation by MFDS was appropriate while 31 institutions (47.7%) answered otherwise. 36 institutions answered that HRPP evaluation and accreditation by MFDS was credible while 29 institutions (44.5%) answered that HRPP evaluation method and accreditation by MFDS was not credible. Conclusion: 1. MFDS's HRPP accreditation program can facilitate the main objective of HRPP and MFDS's HRPP accreditation program should be encouraged to non-tertiary hospitals by taking small staff size into consideration and issuing accreditation by segregating accreditation. 2. While issuing Institution for the education of persons conducting clinical trial status as a benefit of MFDS's HRPP accreditation program, it can also hinder access to MFDS's HRPP accreditation program. It should also be considered that the non-contact culture during COVID-19 pandemic eliminated time and space limitation for education. 3. For clinical research conducted internally by an institution, internal audit is the most effective and sole method of protecting safety and right of the test subjects and integrity for research in Korea. For this reason, regardless of the size of the institution, an internal audit should be enforced. 4. It is necessary for KAIRB and MFDSto improve HRPP awareness by advocating and educating the concept and necessity of HRPP in clinical research. 5. A new HRPP accreditation system should be setup for all clinical research with human subjects, including Investigational New Drug (IND) application in near future.

최근 수출입기업은 무역대금 결제과정과 방식을 선택하면서 신용장보다 T/T 송금과 Surrender B/L을 더 유용하게 이용하고 있으며 신(新)무역물류환경의 특성이 4IR 시대에 들어 강력하게 작용하고 있어 서류에 기반한 무역거래가 선하증권의 전자화나 스마트 계약의 발전으로 인해 새로운 국면을 맞이하고 있다. 본 연구의 목적은 수출기업이 협상 요인에 따라 수출대금 결제유형 선택이 달라지는지를 검증하고 신(新)무역물류환경의 특성을 적용하여 논하는 것이다. 분석을 위한 데이터는 설문을 통해 수집하였으며, 업체 직접방문, e-mail, fax, 온라인 설문, 등기우편회수 등으로 회수하였다. 설문배포기간은 2023년 2월 1일~2023년 4월 30일까지이며 2,000부가 배포되어 447부가 회수되고(회수율 22.4%), 본 연구의 목적에 부적합한 111부를 제외한 최종 336부의 데이터가 사용되었다. 아래는 연구의 결과를 나타낸다. 첫째, 협상 요인 중 수출기업이 가지는 제품 차별성은 수출대금 결제유형 선택에 유의한 영향을 미치지 못하였다. 둘째, 협상 요인 중 수출기업이 인식하는 수입기업 구매우위가 높아질수록 사후송금방식이 더 큰 가능성으로 선택되었다. 본 연구는 이와 같은 분석 결과에 더하여 향후 수출기업이 수출대금 결제유형을 선택하면서 신(新)무역물류환경의 특성이 적용된 블록체인기술기반 선하증권, 무역금융플랫폼 등과 같은 새로운 방식의 결제를 고려해야 할 필요성을 제언하였다. 따라서 수출기업은 예컨대 선하증권 위기현상에 대응하는 무역서류의 디지털화 시도 등에 지속적인 관심을 보여야 할 것이고, 후속 연구에서는 국내의 부족한 사회적 인식을 해외선진연구를 통해 제고할 필요가 있을 것으로 기대한다.

수도의 다수확을 위하여 근래 다비재배의 경향이 높아가고 있는 반면에 등숙률의 저하가 증수저해요인으로 크게 문제되고 있다. 특히 최근 육성된 통일품종은 이점이 더 심각한 바 있어 등숙의 향상책을 모색하고저 1970년부터 1972년까지 3개년간에 걸쳐 수원 작물시험장포장과 인공기상실에서 주로 진흥과 통일을 공시하여 증숙에 관한 일련의 실험을 시행한 바 그 결과를 요약하면 다음과 같다. 1. 통일의 곡립은 발아등 종래품종에 비하여 세장하고 곡립의 폭 및 두께가 작으며 비중과의 상관관계는 진흥에 있어서는 곡립의 무게, 두께, 폭 및 길이의 순으로 낮으나 통일은 무게, 폭, 두께 및 길이의 순으로 낮았다. 2. 비중별 립수분포에 있어서 종래의 Japonica도는 비중 1.18을 정점으로 대부분 1.12이상에 분포하고 있으나 통일계통에서는 1.12이하의 곡립도 상당수 분포하였고 진흥이 비중 1.06이하에서 정현비율이 급감하고 있으나 통일에 있어서는 비중 1.20에서 0.96까지의 곡립의 정현비율이 별로 차이가 없으므로 1.06을 등숙립의 선별기준으로 삼는 것은 불합리한 것으로 인정된다. 3. 출수후의 등숙속도는 품종간차이가 현저하며 대체로 한랭지 재배품종일수록 느렸으며 통일은 원래 등숙이 빠른 편이나 등숙후기에는 기온의 저하로 인하여 그 속도가 떨어졌다. 4. 지발분얼 또는 약세분얼은 수당영화수도 적을 뿐 아니라 등숙률도 낮은데 통일은 지발분얼이 많고 이들은 저온하에서 출수하여 수전일수가 연장되고 등숙률이 떨어졌다. 5. 통일의 엽신은 짧고 넓으며 엽신전개력은 다비조건에서는 진흥만큼 크고 또 엽의 경사각도는 적어 수광태세가 양호하였다. 통일 엽신의 단위동화능력은 고온하에서는 비교적 크나 저온하에서는 떨어졌다. 6. 통일은 단간이며 하위절간이 짧고 굵어서 도복저항성이 크고 출수전 저장탄수화물이 많았으며 인산, 규산, 석회, 망간 및 마그네슘 등의 체내함유율이 높았다. 7. 통일은 비교적 많은 영화수를 가지고 있고 진흥이 영화수와 등숙률간에 유의적인 역상관이 있음에 비하여 통일은 고온다조하에서는 영화수가 많아도 등숙률은 떨어지지 않고 영화수증가에 비례하여 수량이 많아졌다. 8. 진흥에 비하여 통일의 뿌리는 천근성이며 고온하에서는 그 활력이 컸으나 저온시에는 엽신이 황갈색으로 변하고 그 변색정도에 비례해서 뿌리의 활력도 떨어졌다. 9. 통일은 수광태세가 좋고 동화일호흡균형상 유리한 생산구조를 갖어 진흥보다 이상적인 모형이었다. 10. 수원지방의 수도보통기재배에 있어서 수량생산기간의 일사량은 비교적 풍부한 편이나 8월25일이후에 출수할 때에는 평균기온이 22$^{\circ}C$이하로 빠르게 하강하므로서 기온이 보다 등숙의 제한요인으로 인정된다. 11. 진흥이 저온하에서도 등숙율이 비교적 높은데 통일의 등숙적온은 $25^{\circ}C$이상이며 21$^{\circ}C$이하에서는 완전등숙이 거의 불가능하였다. 12. 진흥은 감광성이 비교적 크고 감온성은 중정도인데 비하여 통일은 감광성은 작으나 기본영양생장성과 저온하의 출수지연도가 컸었다. 13. 진흥은 질소의 후기중점시비에 의하여 등숙율이 향상되고 증수되었으나 통일에 있어서는 기비중점으로 질소를 시용하여 영화를 많이 확보하여도 등숙율저하가 적고 오히려 증수되였다. 14. 진흥은 만식적응성이 비교적 크나 통일은 조식효과가 크고 만식하면 출수가 지연되고 등숙온도가 낮아져서 등숙율과 수량이 떨어졌다. 15. 통일은 내비성과 밀식적응성이 커서 다비밀식조건에서 그 다수성을 발휘하는 특성을 가졌으며 주수 및 묘수증가에 의하여 수전일수가 단축되고 등숙률이 향상되었다. 16. 재식거리를 좁히고 어느 정도 주당묘수를 늘리면 강세분얼비율이 높아졌다. 17. 인산은 저온시에는 등숙율을 상당히 향상시켰다. 이상을 요약해보면 종래품종들의 등숙향상을 꾀하자면 8월20일이전에 출수시켜야 하며 10a당 질소 7.5kg 이상의 과다한 기비를 억제하고 후기중점으로 시비하여 동화효율을 높여야할 것이다. 한편 통일은 곡립이 세장하고 식물체가 작고 뭉툭한 등 종래품종과 판이한 외부형태와 더불어 그 생리생태적 특성도 상이한 점이 많으므로 등숙립선별, 도정 및 재배법상에도 종전품종과 다른 고려가 있어야 할 것이다. 즉 등숙립 선별기준에 대하여는 통일의 비중별 입수분포 및 정현비율로 보아 종래의 등숙립 선별기준인 비중 1.06 보다는 0.96을 적용하는 것이 합리적이고 도정상으로는 통일의 곡립이 세장하고 폭 및 두께가 작다는 것을 고려하여야 한다. 재배법에 있어서 통일의 등숙률이 낮은 원인이 주로 약세분얼이 많고 저온하에서는 출수가 지연되고 뿌리와 엽신의 기능이 저하되며 불임이 증가되는 것으로 판명되었고 그 외에 통일은 다비밀식적응성이 크므로 등숙향상과 수량 증대를 위해서는 적극적인 방법으로서 우선 견실하고 큰 묘를 가능한 한 조식하고 다비밀식상태로 재배하되 충분한 기비를 시용하고 묘수를 3본 내외로 심고 인산 및 규산등을 충분히 시용하여야 할 것이다.

Introduction Recently, changes in the patterns and concepts of maternity care, in both developing and developed countries have been accelerating. An outstanding development in this field is the number of deliveries taking place in hospitals or maternity centers. In Korea, however, more than 90% of deliveries are carried out at home with the help of untrained relatives or even without helpers. It is estimated that less than 10% of deliveries are assisted by professional persons such as a physician or a midwife. Taking into account the shortage of professional person i11 rural Korea, it is difficult to expect widespread prenatal, postnatal, and delivery care by professional persons in the near future, It is unrealistic, therefore, to expect rapid development of MCH care by professional persons in rural Korea due to economic and sociological reasons. Given these conditions. it is reasonable that an educated village women could used as a "maternity aid", serving simple and technically easy roles in the MCH field, if we could give such a women incentive to do so. The midwife and physician are assigned difficult problems in the MCH field which could not be solved by the village worker. However, with the application of the village worker system, we could expect to improve maternal and child hoalth through the replacement of untrained relatives as birth attendants with educated and trained maternity aides. We hope that this system will be a way of improving MCH care, which is only one part of the general health services offered at the local health centre level. Problems of MCH in rural Korea The field of MCH is not only the weakest point in the medical field in our country hut it has also dropped behind other developing countries. Regarding the knowledge about pregnancy and delivery, a large proportion of our respondents reported having only a little knowledge, while 29% reported that they had "sufficient" knowledge. The average number of pregnancies among women residing in rural areas was 4.3 while the rate of women with 5 or more pregnancies among general women and women who terminated childbearing were 43 and 80% respectively. The rate of unwanted pregnancy among general women was 19.7%. The total rate for complications during pregnancy was 15.4%, toxemia being the major complication. The rate of pregnant women with chronic disease was 7%. Regarding the interval of pregnancy, the rates of pregnancy within 12 months and within 36 months after last delivery were 9 and 49% respectively. Induced abortion has been increasing in rural areas, being as high as 30-50% in some locations. The maternal death rate was shown 10 times higher than in developed countries (35/10,000 live births). Prenatal care Most women had no consultation with a physician during the prenatal period. Of those women who did have prenatal care, the majority (63%) received such care only 1 or 2 times throughout the entire period of pregnancy. Also, in 80% of these women the first visit Game after 4 months of gestation. Delivery conditions This field is lagging behind other public health problems in our country. Namely, more than 95% of the women deliveried their baby at home, and delivery attendance by a professional person occurred only 11% of the time. Attendance rate by laymen was 78% while those receiving no care at all was 16%. For instruments used to cut the umbilical corn, sterilized scissors were used by 19%, non-sterilized scissors by 63% and 16% used sickles. Regarding delivery sheets, the rate of use of clean sheets was only 10%, unclean sheets, vinyl and papers 72%, and without sheets, 18%. The main reason for not using a hospital as a place of delivery was that the women felt they did not need it as they had previously experience easy deliveries outside hospitals. Difficult delivery composed about 5% of the total. Child health The main food for infants (95%) was breast milk. Regarding weaning time, the rates within one year, up to one and half, two, three and more than three years were 28,43,60,81 and 91% respectively, and even after the next pregnancy still continued lactation. The vaccination of children is the only service for child health in rural Korea. As shown in the Table, the rates of all kinds of vaccination were very low and insufficient. Infant death rate was 42 per 1,000 live births. Most of the deaths were caused by preventable diseases. Death of infants within the neonatal period was 83% meaning that deaths from communicable diseases decreased remarkably after that time. Infant deaths which occurred without medical care was 52%. Methods of improvement in the MCH field 1. Through the activities of village health workers (VHW) to detect pregnant women by home visiting and. after registration. visiting once a month to observe any abnormalities in pregnant women. If they find warning signs of abnormalities. they refer them to the public health nurse or midwife. Sterilized delivery kits were distributed to the expected mother 2 weeks prior to expected date of delivery by the VHW. If a delivery was expected to be difficult, then the VHW took the mother to a physician or call a physician to help after birth, the VHW visits the mother and baby to confirm health and to recommend the baby be given proper vaccination. 2. Through the midwife or public health nurse (aid nurse) Examination of pregnant women who are referred by the VHW to confirm abnormalities and to treat them. If the midwife or aid nurse could not solve the problems, they refer the pregnant women to the OB-GY specialist. The midwife and PHN will attend in the cases of normal deliveries and they help in the birth. The PHN will conduct vaccination for all infants and children under 5, years old. 3. The Physician will help only in those cases referred to him by the PHN or VHW. However, the physician should examine all pregnant women at least three times during their pregnancy. First, the physician will identify the pregnancy and conduct general physical examination to confirm any chronic disease that might disturb the continuity of the pregnancy. Second, if the pregnant woman shows any abnormalities the physician must examine and treat. Third, at 9 or 10 months of gestation (after sitting of the baby) the physician should examine the position of the fetus and measure the pelvis to recommend institutional delivery of those who are expected to have a difficult delivery. And of course. the medical care of both the mother and the infants are responsible of the physician. Overall, large areas of the field of MCH would be served by the VHW, PHN, or midwife so the physician is needed only as a parttime worker.

본 종설논문은 살오징어의 기존 및 최근에 새롭게 적용되고 있는 계군 분석방법들을 비교 분석하여 각 분석방법의 장단점과 분석방법간의 상호보완에 대하여 고찰하였다. 살오징어는 북서태평양의 넓은 지역을 회유하는 어종으로 생태계 및 상업적으로 중요한 자원이다. 살오징어는 해양환경변화의 생물학적 지표로서의 가능성을 평가 받고 있으며, 장단기적인 어획량 및 분포역의 변화가 환경 변화와 함께 나타난다. 예를 들어, 1987/1988 무렵에 발생한 기후체제전환 이후 한류성 어종으로 분류되는 명태의 어획량은 급감하여 현재까지 그 영향이 지속되고 있는 반면, 살 오징어 어획량은 크게 증가하였다. 현재까지 명태 어획량의 감소에 대하여 남획과 기후변화에 초점이 맞추어진 해석이 있으나, 뚜렷한 원인 분석은 이루어지지 않고 있다. 그 이유 중 한 가지는 계군 분석에 근거한 생태, 환경적 측면에 대한 정확한 원인 분석이 이루어지지 않고 있는 것과 관련이 된다. 계군은 유사한 생물학적 특징을 가진 개체들이 제한된 영역 내에서 유성생식과정을 통하여 동일한 유전자 풀(gene pool)을 공유하는 집단으로, 동일 계군을 형성하는 개체들은 산란에서 자원으로 가입 후 다시 재생산 과정에 이르기까지 시간 및 공간적으로 각기 다른 환경의 영향을 받을 수 있다. 따라서, 종에 대한 정확한 계군 분석은 자원의 효과적인 관리 및 급격한 변화에 대한 중요한 대응 방안의 역할을 할 수 있다. 살오징어 계군 분석에 적용된 주요 방법은 크게 4가지로 형태학적 방법, 생태학적 방법, 표지방류법, 유전학적 방법이 있다. 형태학적인 방법은 분석방법이 가장 간단하고 다수의 개체를 비교적 쉽게 분석할 수 있지만 각 형질들은 성장기간 동안 환경에 의해 영향을 많이 받게 되어 개체간의 차이가 생긴다. 생태학적 방법은 주로 개체의 생리적인 변화와 분포 및 회유상태, 기생충의 기생상태나 종류 및 기생률 등을 분석, 산란장의 차이를 알아보는 연구이며, 현재 활발히 연구되고 있는 방법으로 유사한 환경에서 생활하는 집단을 알 수 있지만 유전적으로 같은 집단인지는 알기 어렵다. 표지방류법은 직접적인 방법으로 계군의 회유 및 분포, 산란장의 위치를 파악할 수 있지만 수거가 어렵고 초기 단계에는 표식을 하기 어렵다. 수산생물의 계군 분석을 위한 유전학적 방법은 자원관리학적 연구에 관한 기본적 정보를 제공해 왔다. 계군 분석을 위한 유전학적 방법은 이에 사용하는 유전자 마커(marker)의 감도에 따라 결정되며, 유전자 마커의 다형성이 높은 것을 선택해야 한다. 계군 분석을 위한 유전자 마커로는 오랜 기간 동안 동위효소 다형이 사용되어졌으며, 최근에는 mitochondria, microsatellite와 같이 DNA 염기배열 중에서도 변이성이 높은 영역을 선택하여 마커로 이용한 연구가 증가되고 있다. 기존의 형태학적 방법, 표지방류법, 생태학적인 방법들은 살오징어의 생활사, 회유경로, 산란장의 변화 등을 밝혀내어 계군을 파악하는데 많은 기여를 하였지만 여전히 각 해역에 분포하는 살오징어의 계군을 파악하기에는 어려움이 있다. 최근에는 기존의 계군 분석이 지닌 장단점을 비교 분석하여 복합적인 방법의 계군 분석이 이루어지며, 이러한 정보들을 바탕으로 유전학적 방법을 보완한다면 살오징어 자원의 변동에 대한 관리 방안을 마련하는데 도움을 줄 것이다.

아열대산 MK-T2의 생태적 특성조사, 발근 특성 그리고 오디의 형태와 이화학적 특성, 사료가치 검정 평가, MK-T2로 사육한 5령3일차 누에의 아미노산 분석과 누에 에탄올 추출액의 약리효과에 대한 연구를 하여 다음과 같은 결과를 얻어 잎과 오디 등 다용도 $\ulcorner$청강상(淸江桑)$\lrcorner$ 자체개발 품종육성의 기본자료로 활용하였다. 1. 아열대산 MK-T2의 생태적 특성을 조사한 결과 발아 개엽기는 개량뽕과 비교하여 $9{\sim}10$일 빠르며 새순의 발육 또한 67.2 cm로 3 cm 정도 길었으며, 새순의 뽕잎수도 18.6 개로 2개가 많았다. 2. 엽의 형태는 엽장이 엽폭보다 약간 발달한 1.10 비율을 나타내었으며 엽두께, 엽면적은 각각 $228.2{\mu}m,\;225.6cm^2$로서 개량뽕보다 약간 얇거나 작은편이었다. 3. MK-T2는 화주부분이 0.7mm로 짧게 존재하며 주두내면에 드물게 미모(微毛)가 분포하여 장화계구(長花桂區) 계두유모류(桂頭有毛類)에 속한다고 판단이 된다. 4. 고손장비율은 5.7%로서 개량뽕의 12.9%와 비교하여 상당히 우수하지만 무농약재배의 조건에서 충해의 경우 주당 피해율이 88.6%로서 개량뽕의 47.5%의 거의 2배정도 약함을 보여주었다. 5 .무처리 신소삽목시 발근율이 가지의 굵기와 무관하게 100% 발근하여 온대지역의 개량뽕이 15mm 이상에서 10% 발근한 사실과 비교하여 매우 우수한 발근력을 보여주었으며 발근 형태적 특성은 토양과 물 모두 45%비율로 가지의 중부와 하부에서 발근하는 특성을 보여주어 하부에서 발근하는 온대지역의 뽕나무와는 많은 차이를 나타내었다. 6. MK-T2의 오디는 길이가 24.6 mm, 수분율 78.8%, 당도가 19.21 Brix%로 오디용으로 개발된 품보 20, 검설뽕과 비슷한 성적을 나타내었으나 특이하게 pH 4.7로 단맛과 신맛을 함께 지니고 있었다. 7. NK-T2의 사료가치 검정평가 결과 개량뽕과 비교하여 유충기간과 화용비율, 견충비율은 거의 비슷하였으나, 단견중, 견층중. 2만두 수견량은 약간 떨어지는 결과를 보여 엽질이 비교적 우량하다고 평가되었다. 8. MK-T2로 사육한 5령3일차 누에의 아미노산을 분석한 결과 개량뽕을 급이한 대조구 간에는 서로 거의 유사한 아미노산 조성을 보여주었으나 MK-T2를 급이한 시험구의 경우 대조구와 비교하여 Leu에서 차이를 보여주었으며 Ile는 대조구에서는 검출되지 않았으나 MK-T2 시험구에서는 검출되었다. 9. MK-T2로 사육한 5령3일차 누에 에탄올 추출물의 약리효과 검정결과 누에 에탄을 추출물을 투여한 쥐에서 적출한 신장조직에 대한 HE 염색 및 조직면역화학염색 모두에서 조직학적 병징이 나타나지 않았고 $TGF-{\beta}1$ 단백 발현이 거의 확인되지 않는 수준으로 낮아졌다.

Nursing of today has as one of its objectives the solving of problems related to human needs arising from the demands of a rapidly changing society. This nursing objective, I believe, can he attained by the appropriate application of scientific principles in the giving of comprehensive nursing care. Comprehensive nursing care may be defined as nursing care which meets all of the patient's needs. the needs of patients are said to fall into five broad categories: physical needs, psychological needs, environmental needs, socio-economic needs, and teaching needs. Most people who become ill have adjustment problems related to their new situation. Because patient teaching is one of the most important functions of professional nursing, the success of this teaching may be used as a gauge for evaluating comprehensive nursing care. This represents a challenge foe the future. A questionnaire consisting of 67 items was distributed to 200 professional nurses working ill direct patient care at Yonsei University Medical Center in Seoul, Korea. 160 (80,0%) nurses of the total sample returned completed questionnaires 81 (50.6%) nurses were graduates of 3 fear diploma courser 79 (49.4%) nurses were graduates of 4 year collegiate nursing schools in Korea 141 (88,1%) nurses had under 5 years of clinical experience in a medical center, while 19 (11.9%) nurses had more than 5years of clinical experience. Three hypotheses were tested: 1. “Nurses had high levels of concept and knowledge toward patient teaching”-This was demonstrated by the use of a statistical method, the mean average. 2. “Nurses graduating from collegiate programs and diploma school programs of nursing show differences in concepts and knowledge toward patient teaching”-This was demonstrated by a statistical method, the mean average, although the results showed little difference between the two groups. 3. “Nurses having different amounts of clinical experience showed differences in concepts and knowledge toward patient teaching”-This was demonstrated by the use of a statistical method, the mean average. 2. “Nurses graduating from collegiate programs and diploma school programs of nursing show differences in concepts and knowledge toward patient teaching”-This was demonstrated by a statistical method, the mean average, although the results showed little difference between the two groups. 3. “Nurses having different amounts of clinical experience showed differences in concepts and knowledge toward patient teaching”-This was demonstrated by the use of the T-test. Conclusions of this study are as follow: Before attempting the explanation, of the results, the questionnaire will he explained. The questionnaire contained 67 questions divided into 9 sections. These sections were: concept, content, time, prior preparation, method, purpose, condition, evaluation, and recommendations for patient teaching. 1. The nurse's concept of patient teaching: Most of the nurses had high levels of concepts and knowledge toward patient teaching. Though nursing service was task-centered at the turn of the century, the emphasis today is put on patient-centered nursing. But we find some of the nurses (39.4%) still are task-centered. After, patient teaching, only a few of the nurses (14.4%) checked this as “normal teaching.”It seems therefore that patient teaching is often done unconsciously. Accordingly it would he desirable to have correct concepts and knowledge of teaching taught in schools of nursing. 2. Contents of patient teaching: Most nurses (97.5%) had good information about content of patient teaching. They teach their patients during admission about their diseases, tests, treatments, and before discharge give nurses instruction about simple nursing care, personal hygiene, special diets, rest and sleep, elimination etc. 3. Time of patient teaching: Teaching can be accomplished even if there is no time set aside specifically for it. -a large part of the nurse's teaching can be done while she is giving nursing care. If she believes she has to wait for time free from other activities, she may miss many teaching opportunities. But generally proper time for patient teaching is in the midmorning or midafternoon since one and a half or two hours required. Nurses meet their patients in all stages of health: often tile patient is in a condition in which learning is impossible-pain, mental confusion, debilitation, loss of sensory perception, fear and anxiety-any of these conditions may preclude the possibility of successful teaching. 4. Prior preparation for patient teaching: The teaching aids, nurses use are charts (53.1%), periodicals (23.8%), and books (7.0%) Some of the respondents (28.1%) reported that they had had good preparation for the teaching which they were doing, others (27.5%) reported adequate preparation, and others (43.8%) reported that their preparation for teaching was inadequate. If nurses have advance preparation for normal teaching and are aware of their objectives in teaching patients, they can do effective teaching. 5. Method of patient teaching: The methods of individual patient teaching, the nurses in this study used, were conversation (55.6%) and individual discussion (19.2%) . And the methods of group patient teaching they used were demonstration (42.3%) and lecture (26.2%) They should also he prepared to use pamphlet and simple audio-visual aids for their teaching. 6. Purposes of patient teaching: The purposes of patient teaching is to help the patient recover completely, but the majority of the respondents (40.6%) don't know this. So it is necessary for them to understand correctly the purpose of patient teaching and nursing care. 7. Condition of patient teaching: The majority of respondents (75.0%) reported there were some troubles in teaching uncooperative patients. It would seem that the nurse's leaching would be improved if, in her preparation, she was given a better understanding of the patient and communication skills. The majority of respondents in the total group, felt teaching is their responsibility and they should teach their patient's family as well as the patient. The place for teaching is most often at the patient's bedside (95.6%) but the conference room (3.1%) is also used. It is important that privacy be provided in learning situations with involve personal matters. 8. Evaluation of patient teaching: The majority of respondents (76.3%,) felt leaching is a highly systematic and organized function requiring special preparation in a college or university, they have the idea that teaching is a continuous and ever-present activity of all people throughout their lives. The suggestion mentioned the most frequently for improving preparation was a course in patient teaching included in the basic nursing program. 9. Recommendations: 1) It is recommended, that in clinical nursing, patient teaching be emphasized. 2) It is recommended, that insertive education the concepts and purposes of patient teaching he renewed for all nurses. In addition to this new knowledge, methods and materials which can be applied to patient teaching should be given also. 3) It is recommended, in group patient teaching, we try to embark on team teaching.

This study analyzes the effect of Computer Aided Innovation (CAI) to improve R&D Capabilities empirically. Survey was distributed by e-mail and Google Docs, targeting CTO of 235 SMEs. 142 surveys were returned back (rate of return 60.4%) from companies. Survey results from 119 companies (83.8%) which are effective samples except no-response, insincere response, estimated value, etc. were used for statistics analysis. Companies with less than 50billion KRW sales of entire researched companies occupy 76.5% in terms of sample traits. Companies with less than 300 employees occupy 83.2%. In terms of the type of company business Partners (called 'partners with big companies' hereunder) who work with big companies for business occupy 68.1%. SMEs based on their own business (called 'independent small companies') appear to occupy 31.9%. The present status of holding IT system according to traits of company business was classified into partners with big companies versus independent SMEs. The present status of ERP is 18.5% to 34.5%. QMS is 11.8% to 9.2%. And PLM (Product Life-cycle Management) is 6.7% to 2.5%. The holding of 3D CAD is 47.1% to 21%. IT system-holding and its application of independent SMEs seemed very vulnerable, compared with partner companies of big companies. This study is comprised of IT infra and IT Utilization as CAI capacity factors which are independent variables. factors of R&D capabilities which are independent variables are organization capability, process capability, HR capability, technology-accumulating capability, and internal/external collaboration capability. The highest average value of variables was 4.24 in organization capability 2. The lowest average value was 3.01 in IT infra which makes users access to data and information in other areas and use them with ease when required during new product development. It seems that the inferior environment of IT infra of general SMEs is reflected in CAI itself. In order to review the validity used to measure variables, Factors have been analyzed. 7 factors which have over 1.0 pure value of their dependent and independent variables were extracted. These factors appear to explain 71.167% in total of total variances. From the result of factor analysis about measurable variables in this study, reliability of each item was checked by Cronbach's Alpha coefficient. All measurable factors at least over 0.611 seemed to acquire reliability. Next, correlation has been done to explain certain phenomenon by correlation analysis between variables. As R&D capabilities factors which are arranged as dependent variables, organization capability, process capability, HR capability, technology-accumulating capability, and internal/external collaboration capability turned out that they acquire significant correlation at 99% reliability level in all variables of IT infra and IT Utilization which are independent variables. In addition, correlation coefficient between each factor is less than 0.8, which proves that the validity of this study judgement has been acquired. The pair with the highest coefficient had 0.628 for IT utilization and technology-accumulating capability. Regression model which can estimate independent variables was used in this study under the hypothesis that there is linear relation between independent variables and dependent variables so as to identify CAI capability's impact factors on R&D. The total explanations of IT infra among CAI capability for independent variables such as organization capability, process capability, human resources capability, technology-accumulating capability, and collaboration capability are 10.3%, 7%, 11.9%, 30.9%, and 10.5% respectively. IT Utilization exposes comprehensively low explanatory capability with 12.4%, 5.9%, 11.1%, 38.9%, and 13.4% for organization capability, process capability, human resources capability, technology-accumulating capability, and collaboration capability respectively. However, both factors of independent variables expose very high explanatory capability relatively for technology-accumulating capability among independent variable. Regression formula which is comprised of independent variables and dependent variables are all significant (P<0.005). The suitability of regression model seems high. When the results of test for dependent variables and independent variables are estimated, the hypothesis of 10 different factors appeared all significant in regression analysis model coefficient (P<0.01) which is estimated to affect in the hypothesis. As a result of liner regression analysis between two independent variables drawn by influence factor analysis for R&D capability and R&D capability. IT infra and IT Utilization which are CAI capability factors has positive correlation to organization capability, process capability, human resources capability, technology-accumulating capability, and collaboration capability with inside and outside which are dependent variables, R&D capability factors. It was identified as a significant factor which affects R&D capability. However, considering adjustable variables, a big gap is found, compared to entire company. First of all, in case of partner companies with big companies, in IT infra as CAI capability, organization capability, process capability, human resources capability, and technology capability out of R&D capacities seems to have positive correlation. However, collaboration capability appeared insignificance. IT utilization which is a CAI capability factor seemed to have positive relation to organization capability, process capability, human resources capability, and internal/external collaboration capability just as those of entire companies. Next, by analyzing independent types of SMEs as an adjustable variable, very different results were found from those of entire companies or partner companies with big companies. First of all, all factors in IT infra except technology-accumulating capability were rejected. IT utilization was rejected except technology-accumulating capability and collaboration capability. Comprehending the above adjustable variables, the following results were drawn in this study. First, in case of big companies or partner companies with big companies, IT infra and IT utilization affect improving R&D Capabilities positively. It was because most of big companies encourage innovation by using IT utilization and IT infra building over certain level to their partner companies. Second, in all companies, IT infra and IT utilization as CAI capability affect improving technology-accumulating capability positively at least as R&D capability factor. The most of factor explanation is low at around 10%. However, technology-accumulating capability is rather high around 25.6% to 38.4%. It was found that CAI capability contributes to technology-accumulating capability highly. Companies shouldn't consider IT infra and IT utilization as a simple product developing tool in R&D section. However, they have to consider to use them as a management innovating strategy tool which proceeds entire-company management innovation centered in new product development. Not only the improvement of technology-accumulating capability in department of R&D. Centered in new product development, it has to be used as original management innovative strategy which proceeds entire company management innovation. It suggests that it can be a method to improve technology-accumulating capability in R&D section and Dynamic capability to acquire sustainable competitive advantage.

가맹사업에 있어 배타적 영업지역보호정책의 문제는 경제학 및 경영학 분야뿐만 아니라 사회 정치적으로 매우 중요한 쟁점이다. 본 연구는 배타적 영업지역과 관련한 기존 문헌을 토대로 가맹사업에서의 효율성 관점에서 배타적 영업지역보호에 영향을 미치는 변수와 배타적 영업지역 보호가 가맹본부 및 가맹점의 성과에 미치는 영향을 분석하고 있다. 가맹점의 대부분이 중소상인들이란 점을 감안하면 유통정책적으로도 중요한 의미가 있다고 할 수 있다. 본연구는 사회적으로도 잇슈가 될 수 있는 기업의 전략을 타당성과 당위성, 그리고 논리성으로만 평가하는 것이 아니라 실제 자료를 근거로 분석하였다. 또, 정책연구들이 가지고 있는 자료와 이론의 한계를 감안한 탐색적 방법론을 활용하여 보다 실질적이고 현실적용성이 뛰어난 분석을 제안하였다. 분석 결과, 배타적 영업지역보호는 긍정적인 효과가 있기는 하지만 통계적으로 유의하지 못하였으며, 가맹점과 가맹본부간의 로얄티가 많아서 위험공유성향이 클때에는 배타적 영업지역보호를 하지 않는 것이 효과적이었고, 가맹점을 모집하기 위해 배타적 영업지역보호를 해주거나 배타적 영업지역보호를 통해서 가맹사업본부내의 효율성을 키우기 위한 경우에는 긍정적인 효과가 유의하게 나타나는 것으로 밝혀졌다. 하지만 외부경쟁으로부터 직영점을 보호하기 위하거나 시장성장을 활용하기 위한 배타적 영업지역보호는 좋은 성과를 내지 못하였다. 또한 쉽게 배타적 영업지역보호를 할 수 있기에 이런 제도를 도입하는 것도 역시 좋은 성과를 내지 못한 것으로 나타났다. 결과적으로 배타적 영업지역보호가 기업의 운영효율을 증대시키기 위하여 하는 경우는 성과가 좋으나 다른 목적을 위하여 배타적 영업지역보호를 활용하는 것은 바람직한 결과를 못내는 것으로 나타났다. 본 연구는 분석결과를 토대로 영업지역 보호를 획일적으로 활용하거나 법으로 강제하기 보다는 가맹사업본부와 가맹점의 관계 및 상황, 또 동기에 맞추어 탄력적으로 적용하는 것이 바람직하다는 제안을 하고 있으며, 이를 근거로 몇 가지 정책적 시사점을 제시하였다.
