현대 사회에서 부성 콤플렉스의 여성이 증가하는 이유를 크게 두 가지 관점에서 고려할 수 있다. 우선 사회적 요구가 여성으로 하여금 기존의 여성의 입장에서 벗어나 새로운 역할을 강요하고 있다. 이러한 우리 시대의 사회적 요구는 본성을 억압하도록 하는 부성적 특성의 외압으로 작용한다. 따라서 현대의 여성은 저절로 부성상의 지배 하에 놓이게 되는 부성 콤플렉스의 여성이 된다. 또 다른 관점에서 보면 무의식의 보상성에 의하여 부성 콤플렉스의 여성 유형이 증가하고 있다고 볼 수도 있다. 부성상은 언제나 집단의식과 관련되는 심상이다. 집단의식에 문제가 생기고, 이에 대한 해결을 위하여 소위 부성상의 부름을 받은 여성의 경우도 부성 콤플렉스의 여성이 될 것이다. 부성콤플렉스의 여성이 증가하고 있는 현대의 추세는 그만큼 집단 사회의 문제를 폭로하는 것이고, 그에 대한 해결의 욕구가 절실해진 것으로 이해될 수 있다. 부성상의 영향력은 여성에게 긍정적이든 부정적이든 병리적 현상을 야기할 정도로 치명적이다. 그러나 모든 원형상이 그러하듯 그러한 영향력의 이면에는 궁극적으로 도달하고자 하는 목적의미가 숨어 있다. 이를 고려한다면 치명적으로 작용하는 부성상의 요구를 제대로 이해하고, 성공적으로 실현하는 것은, 부성 콤플렉스의 여성 개인에게서는 부성상의 극복이자 동시에 부성상의 치유이고, 궁극적으로는 집단의식이 가진 문제를 해결하게 되는 것이다. 연구를 위하여 부성상의 영향 하에 있는 여성 인물상을 다루는 두 민담을 선택하였다. <심청전>은 긍정적인 부성 콤플렉스의 여성을 위하여, 그리고 <바리공주>는 부정적 부성 콤플렉스의 여성을 위하여 선택되었다. 연구의 진행은 부성상과 관련된 여성 주인공의 민담의 분석심리학적 해석을 통하여 크게 세 가지 국면으로 살펴보려고 하였다. 그 첫 번째는 민담의 해석을 통하여 부성상의 지배 하에 있는 여성이 겪는 전형적인 문제점을 살펴보는 것이다. 특히 부성이 갖는 긍정적 영향력과 부정적 영향력을 여성의 삶과 연결시켜 구체적으로 다룰 것이다. 두 번째는 민담에서 강력한 부성상의 지배로부터 여성 주인공이 어떻게 벗어나는지를 살펴보게 될 것이다. 이는 부성 콤플렉스의 여성 유형이 여성성을 회복하고 전(全)인격적 실현에 이르는 길을 제시하는 내용이 된다. 마지막으로 부성상의 지배 하에 있게 된 여성은 궁극적으로 집단이 가진 문제를 해결하고 치유하도록 부름을 받았다는 관점을 제시할 것이다. 여성 주인공이 성공적으로 부성상에서 벗어나 오히려 부성상의 문제를 해결한다면 이는 집단의 삶에 새로운 면모를 가져다줄 하나의 전형이 될 것이다. 이것이 두민담을 통하여 다루려는 부성 콤플렉스의 진정한 목적의미가 될 것이다.

목적: 우리나라 강원도 내 어린이집, 유치원, 초중고(공교육) 교육시설과 사교육시설을 포함한 교육시설 관련 COVID-19 감염병 집단사례의 역학적 특성과 위험요인을 파악하고자 한다. 방법: 연구기간은 2020년 12월 10일부터 2021년 9월 23일까지 질병관리청 질병보건통합관리시스템에 신고된 강원도 내 코로나19 확진자 5,318명 중 교육시설 관련 집단감염으로 분류된 19개의 교육시설 관련 확진자 407명을 대상으로 조사하였다. 결과: 교육시설 관련 확진자는 19개의 교육시설 총 407명으로 19세 이하는 204명(50.1%) 이었다. 선행 전파자는 가족이 155명(38.1%), 교사125명(30.7%)이었다. 이차감염자가 확진자로부터 노출된 장소는 집이 139명(34.2%)으로 가장 높았다. 총 19개 집단에서 9개 집단의 근원 환자(추정)는 교사로 확인되었다. 교사가 선행 감염원인 경우의 평균 발병률(2.4%)이 학생이 근원 환자(추정)인 집단의 평균 발병률(1.5%)보다 높았다. 또한 교육시설 내 위험도 종합평가 점수가 높은 사교육시설에서 발병률과 2차 발병률이 높았다. 결론: 본 연구에서 교육시설보다는 가정에서의 전파가 더 큰 것이 확인되었고, 교육시설 내 위험도 종합평가점수가 높은 교육시설에서는 교내 발병률이 가정내 발병률보다 높았고, 공교육 시설보다 사교육시설의 위험도 점수가 높은 곳이 많았으며, 교사들이 근원 환자(추정)인 사례가 많았다. 이러한 결과를 근거로 학생들과 더불어 교사들의 방역 수칙 이행에 대한 감시의 강화가 필요하겠다. 또한 지속적인 교육 당국의 모니터링을 통해 감염병 범유행 상황에서 감염으로부터 안전한 환경에서 교육이 이행될 수 있도록 지속적으로 노력해야 할 필요가 있다.

본 연구는 고문헌(古文獻) 기록과 도상자료(圖像資料)를 조사·분석하여 조선시대 수해 방지를 위해 계획적으로 조성된 한양도성(漢陽都城) 내 청계천(淸溪川) 가산(假山)에 식재된 버드나무 수책(樹柵)에 대해 고찰하였다. 그동안 버드나무에 관련된 연구 사례는 있었으나 버드나무의 구체적인 활용사례와 그 역사적 배경을 조사·분석하여 그 원형적 가치를 파악하는 데 목적을 두고 진행된 연구는 찾아보기 어렵다. 이에 본 연구는 조선시대 청계천에 조성된 버드나무 수책의 사례를 확인하고 조성 배경과 지역적 특징을 조명함으로써 그 가치를 재해석하고자 하였다. 본 연구의 주요 내용은 다음과 같다. 조선시대의 수재(水災)는 제일 큰 위해 요소로 작용하였을 것으로 추정된다. 16~18세기 조선은 홍수로 인한 피해가 심각하였다. 영조 시기에 이르러서는 도성의 사산(四山)이 모두 민둥산이 되었는데, 이는 잦은 홍수의 원인이 되었다. 1760년(영조 36)에 영조는 준천사업(濬川事業)을 통해 장마 때마다 넘치는 청계천 바닥을 준설하고 오간수문 양안에 조성된 가산에 버드나무 수책을 조성하여 수해를 예방하고 토양의 유실을 방지하는 조치를 시행하였다. 영조 시기인 18세기 중반에 제작된 《광여도(廣輿圖)》 속의 <도성도(都城圖)>에는 오간수문(五間水門) 앞에 조성된 가산이 보이고, 『신증동국여지승람(新增東國輿地勝覽)』의 기록에서 1760년(영조 36)에 버들을 양쪽 가산에 심었다는 기록을 검증하였으며, 1770년(영조 46) 제작된 <한양도성도(漢陽都城圖)>를 통해 18세기 후반에는 오간수문 근처의 가산 위 버드나무가 숲을 이루어 우거졌던 사실도 확증하였다. 또한 『조선왕조실록(朝鮮王朝實錄)』이나 『승정원일기(承政院日記)』, 『일성록(日省錄)』 등의 고문헌 기록을 통해 청계천 준천사업과 버드나무 수책의 조성이 조선 전기인 15세기부터 조선 후기인 19세기 말까지 계속되었다는 사실을 확인하였다. 본 연구는 홍수 및 수해 방지는 물론 아름다운 경관을 형성하는데 큰 바탕이 되었던 조선시대 버드나무 수책의 조성사례와 그 활용성을 조사함으로써 버드나무가 고유한 문화유산이자 전통 경관자원이었음을 알리고, 버드나무의 역사적 의미를 되새기는 데 의의가 있다.

본고는 문화유산의 보존관리적 측면에서 논란이 되었던 경복궁 자경전(慈慶殿) 꽃담을 대상으로 주요 내력과 도상(圖像) 구성의 실제를 조명하였다. 자경전 꽃담이 현재 모습으로 변형된 시기와 계기를 파악하는 한편 변조 또는 소실된 문양을 확인하고, 의미상 곡해된 축원(祝願) 문구를 재검토하였다. 연구 결과는 향후 자경전 꽃담의 복원을 위한 논의가 이루어질 경우 유의미한 기초자료로 활용될 수 있다. 자경전 꽃담은 크고 작은 부침을 겪으면서 현재에 이르고 있지만, 지대한 영향을 미친 변곡점은 1929년 경복궁에서 개최된 조선박람회로 판단된다. 자경전 일곽의 담장이 조선박람회 준비 중 전시관 건립을 위해 철거되었고, 행사 종료 이후에 다시 복구되었기 때문이다. 자경전 꽃담을 구성하는 문양의 변조와 소실 역시 대부분 조선박람회 종료 이후의 복구 과정에서 기인했을 가능성이 높다. 한국전쟁 직후 이루어진 보수 과정에서 현재 모습으로 변형되었다는 시각도 있지만, 신빙성을 갖춘 정황과 근거는 찾아보기 어렵다. 현재 경도문-여강문 구간의 내벽에는 「성인도리(聖人道理)」로 알려진 문자문이 배열되어 있지만, 도안 형태와 용례를 고려하면 「성자신손(聖子神孫)」이라는 문구로 판독할 수 있다. 일반적인 벽돌담장으로 남아 있는 여강문-연수문 구간의 내벽은 본래 꽃담 형식으로 제작되었으며, 「계계승승(繼繼繩繩)」과 「천세(千世)」로 비정되는 문구가 배열되어 있었다. 연수문-함규문 구간의 경우 현재 무문(無紋) 상태로 남아 있는 내벽 역시 당초에는 기하문과 문자문으로 구성되었으며, 「천수(千壽)」와 「만세만수(萬世萬壽)」로 특정되는 문구도 실존하였다. 연수문-함규문 구간의 외벽에서는 「낙강만세(樂彊萬歲)」로 알려진 문구를 「천세만세(千歲萬歲)」로 판독할 수 있는 여지가 충분하며, 현재 하나의 도곽(圖郭)으로 이루어진 벽면에는 본래 두 개의 도곽이 별도로 구분되어 있었다.

북동 멕시코 만에서 particulate organic carbon(POC)의 시/공간적 변화를 조사하기 위하여, 1997년 11월부터 2000년 8월까지 총 9번의 관측이 이루어 졌으며, 같은 기간 동안 위성자료(해색, 표층수온, 해면고도이상, 표층바람)와 주요 강들 의 유출량이 조사되었다. POC 농도는 내 대륙붕과 미시시피 하구 역에서 높은 값을 (>100 $mg/m^3$) 나타내고 대륙붕과 대륙사면으로 가면서 감소된다. POC의 경년 변화는 상대적으로 1997과 1998년(El $Ni\tilde{n}o$)이 1999과 2000년(La $Ni\tilde{n}a$) 보다 상대적으로 증가되어 나타난다. 이런 현상은 미시시피강 및 다른 주요 강들에 영향을 주는 강우량 변화에 따른 담수 유 입의 변화와 직접적으로 연관되어 있으며, 강우량 변화는 ENSO 현상과 같은 세계 기후변화와 관련이 있는 것으로 사료 된다. 북동 멕시코 만 연안으로 유입되는 주요 강들의 방류량은 초봄에 증가되어 여름과 가을에 감소되지만, 공간적으로 확장된 높은 농도의 POC 분포는 여름 조사기간에서 관측되고, 낮은 농도 및 제한된 확산은 가을과 초 봄 관측에서 나타 난다. 여름철 동안 상대적인 강의 유출량은 봄에 비하여 현저하게 감소하지만, 증가된 표층수온은 수층을 강하게 성층화 시키고 표층에서 부력을 증가시킨다. 이런 조건에서 고농도의 POC를 함유하는 저염수는 상부 대륙사면까지 확장되고 이 는 Loop Current와 Loop Current Eddies의해서 조절된다. 봄과 가을 동안 유출량은 보통이거나 이상을 보이지만, 증가된 바람과 낮은 표층수온으로 인하여 수직적 혼합을 유발하고 이는 높은 농도의 POC를 내 대륙붕에 제한 시키는 것으로 사료된다.

Just before the Korean War, the total number of the North Korean troops was 198,380, while that of the ROK(Republic of Korea) army troops 105,752. That is, the total number of the ROK army troops at that time was 53.3% of the total number of the North Korean army. As of December 2008, the total number of the North Korean troops is estimated to be 1,190,000, while that of the ROK troops is 655,000, so the ROK army maintains 55.04% of the total number of the North Korean troops. If the ROK army continues to reduce its troops according to [Military Reform Plan 2020], the total number of its troops will be 517,000 m 2020. If North Korea maintains the current status(l,190,000 troops), the number of the ROK troops will be 43.4% of the North Korean army. In terms of units, just before the Korean War, the number of the ROK army divisions and regiments was 80% and 44.8% of North Korean army. As of December 2008, North Korea maintains 86 divisions and 69 regiments. Compared to the North Korean army, the ROK army maintains 46 Divisions (53.4% of North Korean army) and 15 regiments (21.3% of North Korean army). If the ROK army continue to reduce the military units according to [Military Reform Plan 2020], the number of ROK army divisions will be 28(13 Active Division, 4 Mobilization Divisions and 11 Local Reserve Divisions), while that of the North Korean army will be 86 in 2020. In that case, the number of divisions of the ROK army will be 32.5% of North Korean army. During the Korean war, North Korea suddenly invaded the Republic of Korea and occupied its capital 3 days after the war began. At that time, the ROK army maintained 80% of army divisions, compared to the North Korean army. The lesson to be learned from this is that, if the ROK army is forced to disperse its divisions because of the simultaneous invasion of North Korea and attack of guerrillas in home front areas, the Republic of Korea can be in a serious military danger, even though it maintains 80% of military divisions of North Korea. If the ROK army promotes the plans in [Military Reform Plan 2020], the number of military units of the ROK army will be 32.5% of that of the North Korean army. This ratio is 2.4 times lower than that of the time when the Korean war began, and in this case, 90% of total military power should be placed in the DMZ area. If 90% of military power is placed in the DMZ area, few troops will be left for the defense of home front. In addition, if the ROK army continues to reduce the troops, it can allow North Korea to have asymmetrical superiority in military force and it will eventually exert negative influence on the stability and peace of the Korean peninsular. On the other hand, it should be reminded that, during the Korean War, the Republic of Korea was attacked by North Korea, though it kept 53.3% of troops, compared to North Korea. It should also be reminded that, as of 2008, the ROK army is defending its territory with the troops 55.04% of North Korea. Moreover, the national defense is assisted by 25,120 troops of the US Forces in Korea. In case the total number of the ROK troops falls below 43.4% of the North Korean army, it may cause social unrest about the national security and may lead North Korea's misjudgement. Besides, according to Lanchester strategy, the party with weaker military power (60% compared to the party with stronger military power) has the 4.1% of winning possibility. Therefore, if we consider the fact that the total number of the ROK army troops is 55.04% of that of the North Korean army, the winning possibility of the ROK army is not higher than 4.1%. If the total number of ROK troops is reduced to 43.4% of that of North Korea, the winning possibility will be lower and the military operations will be in critically difficult situation. [Military Reform Plan 2020] rums at the reduction of troops and units of the ground forces under the policy of 'select few'. However, the problem is that the financial support to achieve this goal is not secured. Therefore, the promotion of [Military Reform Plan 2020] may cause the weakening of military defence power in 2020. Some advanced countries such as Japan, UK, Germany, and France have promoted the policy of 'select few'. However, what is to be noted is that the national security situation of those countries is much different from that of Korea. With the collapse of the Soviet Unions and European communist countries, the military threat of those European advanced countries has almost disappeared. In addition, the threats those advanced countries are facing are not wars in national level, but terrorism in international level. To cope with the threats like terrorism, large scaled army trops would not be necessary. So those advanced European countries can promote the policy of 'select few'. In line with this, those European countries put their focuses on the development of military sections that deal with non-military operations and protection from unspecified enemies. That is, those countries are promoting the policy of 'select few', because they found that the policy is suitable for their national security environment. Moreover, since they are pursuing common interest under the European Union(EU) and they can form an allied force under NATO, it is natural that they are pursing the 'select few' policy. At present, NATO maintains the larger number of troops(2,446,000) than Russia(l,027,000) to prepare for the potential threat of Russia. The situation of japan is also much different from that of Korea. As a country composed of islands, its prime military focus is put on the maritime defense. Accordingly, the development of ground force is given secondary focus. The japanese government promotes the policy to develop technology-concentrated small size navy and air-forces, instead of maintaining large-scaled ground force. In addition, because of the 'Peace Constitution' that was enacted just after the end of World War II, japan cannot maintain troops more than 240,000. With the limited number of troops (240,000), japan has no choice but to promote the policy of 'select few'. However, the situation of Korea is much different from the situations of those countries. The Republic of Korea is facing the threat of the North Korean Army that aims at keeping a large-scale military force. In addition, the countries surrounding Korea are also super powers containing strong military forces. Therefore, to cope with the actual threat of present and unspecified threat of future, the importance of maintaining a carefully calculated large-scale military force cannot be denied. Furthermore, when considering the fact that Korea is in a peninsular, the Republic of Korea must take it into consideration the tradition of continental countries' to maintain large-scale military powers. Since the Korean War, the ROK army has developed the technology-force combined military system, maintaining proper number of troops and units and pursuing 'select few' policy at the same time. This has been promoted with the consideration of military situation in the Koran peninsular and the cooperation of ROK-US combined forces. This kind of unique military system that cannot be found in other countries can be said to be an insightful one for the preparation for the actual threat of North Korea and the conflicts between continental countries and maritime countries. In addition, this kind of technology-force combined military system has enabled us to keep peace in Korea. Therefore, it would be desirable to maintain this technology-force combined military system until the reunification of the Korean peninsular. Furthermore, it is to be pointed out that blindly following the 'select few' policy of advanced countries is not a good option, because it is ignoring the military strategic situation of the Korean peninsular. If the Republic of Korea pursues the reduction of troops and units radically without consideration of the threat of North Korea and surrounding countries, it could be a significant strategic mistake. In addition, the ROK army should keep an eye on the fact the European advanced countries and Japan that are not facing direct military threats are spending more defense expenditures than Korea. If the ROK army reduces military power without proper alternatives, it would exert a negative effect on the stable economic development of Korea and peaceful reunification of the Korean peninsular. Therefore, the desirable option would be to focus on the development of quality of forces, maintaining proper size and number of troops and units under the technology-force combined military system. The tableau above shows that the advanced countries like the UK, Germany, Italy, and Austria spend more defense expenditure per person than the Republic of Korea, although they do not face actual military threats, and that they keep achieving better economic progress than the countries that spend less defense expenditure. Therefore, it would be necessary to adopt the merits of the defense systems of those advanced countries. As we have examined, it would be desirable to maintain the current size and number of troops and units, to promote 'select few' policy with increased defense expenditure, and to strengthen the technology-force combined military system. On the basis of firm national security, the Republic of Korea can develop efficient policies for reunification and prosperity, and jump into the status of advanced countries. Therefore, the plans to reduce troops and units in [Military Reform Plan 2020] should be reexamined. If it is difficult for the ROK army to maintain its size of 655,000 troops because of low birth rate, the plans to establish the prompt mobilization force or to adopt drafting system should be considered for the maintenance of proper number of troops and units. From now on, the Republic of Korean government should develop plans to keep peace as well as to prepare unexpected changes in the Korean peninsular. For the achievement of these missions, some options can be considered. The first one is to maintain the same size of military troops and units as North Korea. The second one is to maintain the same level of military power as North Korea in terms of military force index. The third one is to maintain the same level of military power as North Korea, with the combination of the prompt mobilization force and the troops in active service under the system of technology-force combined military system. At present, it would be not possible for the ROK army to maintain such a large-size military force as North Korea (1,190,000 troops and 86 units). So it would be rational to maintain almost the same level of military force as North Korea with the combination of the troops on the active list and the prompt mobilization forces. In other words, with the combination of the troops in active service (60%) and the prompt mobilization force (40%), the ROK army should develop the strategies to harmonize technology and forces. The Korean government should also be prepared for the strategic flexibility of USFK, the possibility of American policy change about the location of foreign army, radical unexpected changes in North Korea, the emergence of potential threat, surrounding countries' demand for Korean force for the maintenance of regional stability, and demand for international cooperation against terrorism. For this, it is necessary to develop new approaches toward the proper number and size of troops and units. For instance, to prepare for radical unexpected political or military changes in North Korea, the Republic of Korea should have plans to protect a large number of refugees, to control arms and people, to maintain social security, and to keep orders in North Korea. From the experiences of other countries, it is estimated that 115,000 to 230,000 troops, plus ten thousands of police are required to stabilize the North Korean society, in the case radical unexpected military or political change happens in North Korea. In addition, if the Republic of Korea should perform the release of hostages, control of mass destruction weapons, and suppress the internal wars in North Korea, it should send 460,000 troops to North Korea. Moreover, if the Republic of Korea wants to stop the attack of North Korea and flow of refugees in DMZ area, at least 600,000 troops would be required. In sum, even if the ROK army maintains 600,000 troops, it may need additional 460,000 troops to prepare for unexpected radical changes in North Korea. For this, it is necessary to establish the prompt mobilization force whose size and number are almost the same as the troops in active service. In case the ROK army keeps 650,000 troops, the proper number of the prompt mobilization force would be 460,000 to 500,000.

The purpose of the study is to identify the lived experience of mothers who have children with cerebral palsy in order to understand their agony. Moreover, the result of study was to find some nursing intervention for disabled children and their mothers. For this purpose, ten mothers who are willing to cooperate with this research were selected at random from those who have children with the cerebral palsy, currently using the municipal facilities for the handicapped with cerebral malfunction. Data collection was done from October 4, 1994 th December 31, 1994. The data were collected by asking the mothers mentioned above with some unstructured open-ended questions, recorded on the tapes with permission by the interviewee in order to prevent missing of the interviewed contents. These collected data have been substantiated and properly analyzed on the basis of phenomenological approach initiated by Colaizzi's method. The results and validity are proved to be credible by means of the individual checking of the interviewed mothers. The results of this study are as follows : 1. When the mother is first informed of the diagnosis of cerebral palsy on her child, she usually misses the crucial timing needed for proper treatment of the child's disorder because she is notified through the doctor's indifference and his apparently inactive, matter-of-fact attitude. At first she suspects the doctor's diagnosis and tries to attribute it to the unknown cause from a certain genetic problem and then she quickly wants to deny the whole situation that her child is really suffering from the cerebral palsy. The reality is too much for her to accept as it is and she would not believe her child is abnormal. Therefore, she even attempts depend on the power of God for its solution. 2. The mother, who goes thorough this kind of uncommon experiences, is totally devoted to the treatment and care of the child and completely ignores her own life and happiness. At the same time, she feels sorry for her other normal children she believes having not enough care and concern. Also, she feels sorry for the sick child when the child's brothers or sisters show special concern for the patient out of sympathy. It is sorry and not satisfied for her that the child is growing with abnormality and neighbor other around have inappropriate attitudes. Likewise, she is discontent with her husband's lack of concern about the child's treatment. She believes that the health care system in this society isn't fulfilling its due purpose. In the state of her utmost distress and anxiety, she always feels the need of competent consultants, and is angry about that her child is treated as an abnormal being, she is trying to hide the child from other people and to make him or her disappear, if possible. Although she doesn't have harmonious relation with her husband, she id happy when he shows his affection for the child and she feels relieved and thankful when the relatives don't mention about the child's condition Since the child's overall status of health is continuously in unstable conditions, requiring her all-time readiness for an emergency, she feels guilty of her child's illness toward the fEmily members as if it was her own fault to have borne such an abnormal child and she feels responsible for the child morally and financially if necessary Because her life is centered on taking care of the child, she cannot afford to enjoy her own life and happiness. She is a lonely mother, fatigued, with no proper relationship with other people around her. With this sense of guilt and responsibility as a mother of an unusual disease, she has no choice but to grieve her destiny from which she is not allowed to escape. 3. Nevertheless, the mother with the child suffering from the cerebral palsy does not easily give up the hope of getting her child cured and she believes that in the long run, though slower than hoped, her abnormal son or daughter will be eventually cured to become a normal sibling someday. This kind of hope is sustained by the mother's strong faith coming from observing the progress of other similar children getting better. Sometimes she is encouraged to have this faith by other mothers who share the same painful experiences, believing that her child will improve even more rapidly than others with the same palsy. Full of hope, she painstakingly waits for the child's healing. Moreover, she plans to have another child. she thinks that the patient child's brothers and sisters only can truly understand and look after the patients. However, when she notices that the progress of other children under the treatment does not look so hopeful, she is distressed by the thoughts that her child may never get well. Too, she is worried that the patient's brother or sister will be born as the same invalid with the cerebral disease. She is discouraged to have another baby as much as she is encouraged to. She is also troubled by the thought that in case she has another baby, she will have to be forced. to neglect the patient child, especially when she does have an extra hand or some reliable person to help her with taking care of the patient.

Clubroot disease of crucifers has occurred since 1957. It has spread to the whole China, especially in the southwest and nourtheast where it causes 30-80% loss in some fields. The disease has being expanded in the recent years as seeds are imported and the floating seedling system practices. For its effective control, the Ministry of Agriculture of China set up a program in 2010 and a research team led by Dr. Yueqiu HE, Yunnan Agricultural University. The team includes 20 main reseachers of 11 universities and 5 institutions. After 5 years, the team has made a lot of progresses in disease occurrence regulation, resources collection, resistance identification and breeding, biological agent exploration, formulation, chemicals evaluation, and control strategy. About 1200 collections of local and commercial crucifers were identified in the field and by artificiall inoculation in the laboratories, 10 resistant cultivars were breeded including 7 Chinese cabbages and 3 cabbages. More than 800 antagostic strains were isolated including bacteria, stretomyces and fungi. Around 100 chemicals were evaluated in the field and greenhouse based on its control effect, among them, 6 showed high control effect, especially fluazinam and cyazofamid could control about 80% the disease. However, fluzinam has negative effect on soil microbes. Clubroot disease could not be controlled by bioagents and chemicals once when the pathogen Plasmodiophora brassicae infected its hosts and set up the parasitic relationship. We found the earlier the pathogent infected its host, the severer the disease was. Therefore, early control was the most effective. For Chinese cabbage, all controlling measures should be taken in the early 30 days because the new infection could not cause severe symptom after 30 days of seeding. For example, a biocontrol agent, Bacillus subtilis Strain XF-1 could control the disease 70%-85% averagely when it mixed with seedling substrate and was drenching 3 times after transplanting, i.e. immediately, 7 days, 14 days. XF-1 has been deeply researched in control mechanisms, its genome, and development and application of biocontrol formulate. It could produce antagonistic protein, enzyme, antibiotics and IAA, which promoted rhizogenesis and growth. Its The genome was sequenced by Illumina/Solexa Genome Analyzer to assembled into 20 scaffolds then the gaps between scaffolds were filled by long fragment PCR amplification to obtain complet genmone with 4,061,186 bp in size. The whole genome was found to have 43.8% GC, 108 tandem repeats with an average of 2.65 copies and 84 transposons. The CDSs were predicted as 3,853 in which 112 CDSs were predicted to secondary metabolite biosynthesis, transport and catabolism. Among those, five NRPS/PKS giant gene clusters being responsible for the biosynthesis of polyketide (pksABCDEFHJLMNRS in size 72.9 kb), surfactin(srfABCD, 26.148 kb, bacilysin(bacABCDE 5.903 kb), bacillibactin(dhbABCEF, 11.774 kb) and fengycin(ppsABCDE, 37.799 kb) have high homolgous to fuction confirmed biosynthesis gene in other strain. Moreover, there are many of key regulatory genes for secondary metabolites from XF-1, such as comABPQKX Z, degQ, sfp, yczE, degU, ycxABCD and ywfG. were also predicted. Therefore, XF-1 has potential of biosynthesis for secondary metabolites surfactin, fengycin, bacillibactin, bacilysin and Bacillaene. Thirty two compounds were detected from cell extracts of XF-1 by MALDI-TOF-MS, including one Macrolactin (m/z 441.06), two fusaricidin (m/z 850.493 and 968.515), one circulocin (m/z 852.509), nine surfactin (m/z 1044.656~1102.652), five iturin (m/z 1096.631~1150.57) and forty fengycin (m/z 1449.79~1543.805). The top three compositions types (contening 56.67% of total extract) are surfactin, iturin and fengycin, in which the most abundant is the surfactin type composition 30.37% of total extract and in second place is the fengycin with 23.28% content with rich diversity of chemical structure, and the smallest one is the iturin with 3.02% content. Moreover, the same main compositions were detected in Bacillus sp.355 which is also a good effects biocontol bacterial for controlling the clubroot of crucifer. Wherefore those compounds surfactin, iturin and fengycin maybe the main active compositions of XF-1 against P. brassicae. Twenty one fengycin type compounds were evaluate by LC-ESI-MS/MS with antifungal activities, including fengycin A $C_{16{\sim}C19}$, fengycin B $C_{14{\sim}C17}$, fengycin C $C_{15{\sim}C18}$, fengycin D $C_{15{\sim}C18}$ and fengycin S $C_{15{\sim}C18}$. Furthermore, one novel compound was identified as Dehydroxyfengycin $C_{17}$ according its MS, 1D and 2D NMR spectral data, which molecular weight is 1488.8480 Da and formula $C_{75}H_{116}N_{12}O_{19}$. The fengycin type compounds (FTCPs $250{\mu}g/mL$) were used to treat the resting spores of P. brassicae ($10^7/mL$) by detecting leakage of the cytoplasm components and cell destruction. After 12 h treatment, the absorbencies at 260 nm (A260) and at 280 nm (A280) increased gradually to approaching the maximum of absorbance, accompanying the collapse of P. brassicae resting spores, and nearly no complete cells were observed at 24 h treatment. The results suggested that the cells could be lyzed by the FTCPs of XF-1, and the diversity of FTCPs was mainly attributed to a mechanism of clubroot disease biocontrol. In the five selected medium MOLP, PSA, LB, Landy and LD, the most suitable for growth of strain medium is MOLP, and the least for strains longevity is the Landy sucrose medium. However, the lipopeptide highest yield is in Landy sucrose medium. The lipopeptides in five medium were analyzed with HPLC, and the results showed that lipopeptides component were same, while their contents from B. subtilis XF-1 fermented in five medium were different. We found that it is the lipopeptides content but ingredients of XF-1 could be impacted by medium and lacking of nutrition seems promoting lipopeptides secretion from XF-1. The volatile components with inhibition fungal Cylindrocarpon spp. activity which were collect in sealed vesel were detected with metheds of HS-SPME-GC-MS in eight biocontrol Bacillus species and four positive mutant strains of XF-1 mutagenized with chemical mutagens, respectively. They have same main volatile components including pyrazine, aldehydes, oxazolidinone and sulfide which are composed of 91.62% in XF-1, in which, the most abundant is the pyrazine type composition with 47.03%, and in second place is the aldehydes with 23.84%, and the third place is oxazolidinone with 15.68%, and the smallest ones is the sulfide with 5.07%.

公司生产不同功能, 设计, 颜色的产品. 产品扩散的出现有三个不同的原因. 当存在规模经济, 当这种产品和别的产品一起生产时, 单位成本比单独生产要低. 二, 消费者是异构的, 即它们具有不同的品味, 喜好, 或价格弹性. 一家公司可赚取细分为具有类似特点的不同群体的消费者更多的利润. 例如, 产品扩散通过更准确地满足不同消费者的需要来帮助公司增加利润. 产品扩散的第三个原因是基于战略. 生产一定数量的产品, 不仅可以阻止通过提供给一些少数市场的产品进入, 也使得公司可以有效地应付低价格进入. 通过生产各种产品, 公司可以减少利基, 使潜在进入者有较少进入的诱因. 此外, 企业可以生产新产品来应对进入, 我们称之为战斗品牌. 也就是说, 当一个进入者试图以低廉的价格吸引消费者, 已存在者介绍新的低质量的产品, 同时保持现有产品的价格. 产品扩散的缺点是同型装配. 一些买了高价位的产品的消费者会转向低价位的产品. 此外, 当新产品与对手现有的产品的异化程度不高时, 由于激烈的竞争, 产品扩散会降低利润. 许多研究已经在经济分析和市场营销等领域的产品线竞争的影响. 它们展示了一个垄断者可以通过调整质量来解决市场中的消费者对质量的偏好不同的同型装配的问题. 他们发现, 喜欢高品质的产品的消费者将获得他或她最喜欢的质量, 但没有这方面的偏好的消费者将获得比他或她所喜爱的质量低的产品. 本研究分析了产品的竞争在一个双头垄断市场, 两种不同类型的消费者对质量偏好的影响. 我假设这两家公司将在这个意义上的不对称, 一个运营商可以同时生产高, 低质量的产品, 而一个进入者只能产生低质量的产品. 产品扩散的影响是可以通过比较市场结果来解释, 当已存在的运营商生产两种产品和只生产一种产品时. 在这个案例中, 当已存在的运营商只生产高品质的产品, 由于激烈的竞争, 在喜欢低质量产品的消费群中低质量的产品价格趋于下降. 但由于缺乏竞争, 在喜欢高质量产品的消费群中价格会上涨. 据了解, 当企业在进行价格竞争时, 理想状况是当公司的对 手提高价格时, 此公司也提高价格, 这被称为战略补充. 由于价格是战略性的补充, 我们有两种相反的效果. 事实证明, 一个高品质的产品价格上升, 因为竞争力减弱的积极作用超过了战略互补的负面影响. 这意味着, 已存在的运营商推出了低质量的产品时还需要增加高品质产品的价格. 然而, 在进入者的低质量产品的价格变化是模糊的. 二, 此案例中, 已存在的运营商只生产低品质的产品, 在偏好低质量的消费群中价格往往增加. 但在偏好高质量的消费群中价格往往下降. 低质量产品的价格下降是因为负面影响大于正面影响. 而且, 当已存在的运营商生产两种产品时, 其低质量产品的价格往往较高, 尽管两家的低品质的产品质量一样. 此原因由于对高品质产品价格的负面影响, 运营商没有较大的动机去降低低品质产品的价格. 事实上, 竞争的产品线对利润的影响不仅取决于价格变化, 还取决于销售和同型装配. 如果在边际成本同产品质量的差异相比是适中的话, 产品扩散的积极影响大于负面影响, 从而增加利润. 此外, 如果成本差异是非常大(小), 运营商最好只生产一种低 (高)质量的产品. 而且, 本研究还分析了当公司通过关注战斗品牌来决定产品特征时, 竞争产品线的影响. 最近, 大韩航空和韩亚航空公司建立了廉价航空线路, 分别是Jin线路和釜山线. 来应对Hansung航空和济州航空. 另外, 很多网上书店也进入市场, 例如处于领先地位的实体书店Kyobo已经有了自己的网上书店. 通过战斗品牌, 在它的低品质产品跟新成员比起来有差别时, 一个具有高品质产品的运营商通过生产更多的低质量产品可以增加利润.

언어모델은 순차적으로 입력된 자료를 바탕으로 다음에 나올 단어나 문자를 예측하는 모델로 언어처리나 음성인식 분야에 활용된다. 최근 딥러닝 알고리즘이 발전되면서 입력 개체 간의 의존성을 효과적으로 반영할 수 있는 순환신경망 모델과 이를 발전시킨 Long short-term memory(LSTM) 모델이 언어모델에 사용되고 있다. 이러한 모형에 자료를 입력하기 위해서는 문장을 단어 혹은 형태소로 분해하는 과정을 거친 후 단어 레벨 혹은 형태소 레벨의 모형을 사용하는 것이 일반적이다. 하지만 이러한 모형은 텍스트가 포함하는 단어나 형태소의 수가 일반적으로 매우 많기 때문에 사전 크기가 커지게 되고 이에 따라 모형의 복잡도가 증가하는 문제가 있고 사전에 포함된 어휘 외에는 생성이 불가능하다는 등의 단점이 있다. 특히 한국어와 같이 형태소 활용이 다양한 언어의 경우 형태소 분석기를 통한 분해과정에서 오류가 더해질 수 있다. 이를 보완하기 위해 본 논문에서는 문장을 자음과 모음으로 이루어진 음소 단위로 분해한 뒤 입력 데이터로 사용하는 음소 레벨의 LSTM 언어모델을 제안한다. 본 논문에서는 LSTM layer를 3개 또는 4개 포함하는 모형을 사용한다. 모형의 최적화를 위해 Stochastic Gradient 알고리즘과 이를 개선시킨 다양한 알고리즘을 사용하고 그 성능을 비교한다. 구약성경 텍스트를 사용하여 실험을 진행하였고 모든 실험은 Theano를 기반으로 하는 Keras 패키지를 사용하여 수행되었다. 모형의 정량적 비교를 위해 validation loss와 test set에 대한 perplexity를 계산하였다. 그 결과 Stochastic Gradient 알고리즘이 상대적으로 큰 validation loss와 perplexity를 나타냈고 나머지 최적화 알고리즘들은 유사한 값들을 보이며 비슷한 수준의 모형 복잡도를 나타냈다. Layer 4개인 모형이 3개인 모형에 비해 학습시간이 평균적으로 69% 정도 길게 소요되었으나 정량지표는 크게 개선되지 않거나 특정 조건에서는 오히려 악화되는 것으로 나타났다. 하지만 layer 4개를 사용한 모형이 3개를 사용한 모형에 비해 완성도가 높은 문장을 생성했다. 본 논문에서 고려한 어떤 시뮬레이션 조건에서도 한글에서 사용되지 않는 문자조합이 생성되지 않았고 명사와 조사의 조합이나 동사의 활용, 주어 동사의 결합 면에서 상당히 완성도 높은 문장이 발생되었다. 본 연구결과는 현재 대두되고 있는 인공지능 시스템의 기초가 되는 언어처리나 음성인식 분야에서 한국어 처리를 위해 다양하게 활용될 수 있을 것으로 기대된다.
