거대한 데이터베이스로부터 중요하고 의미 있는 정보를 찾아내기 위해 데이터 마이닝 기법들이 사용되며, 패턴 마이닝은 이러한 데이터 마이닝을 위한 중요한 기법 중에 하나이다. 패턴 마이닝은 거대 데이터베이스로부터 유용한 패턴을 찾아내는 기법이며, 패턴 마이닝 분야 중에 하나인 빈발 패턴 마이닝은 데이터베이스에서 최소 임계치 이상의 빈도수를 가지는 빈발 패턴을 마이닝 한다. 전통적인 빈발 패턴 마이닝은 전체 데이터베이스에 대한 단일 최소 임계치를 기반으로 중요 빈발 패턴을 마이닝 한다. 단일 최소 임계치 모델은 데이터베이스 내 모든 아이템이 동일한 특성을 가진다고 암묵적으로 가정한다. 그러나 실제 응용에서는 각 아이템들이 개별적인 특성을 가지고 있을 수 있으며, 따라서 이를 반영한 패턴 마이닝 기법이 요구된다. 데이터베이스 내 아이템들의 이러한 특성이 반영되지 않은 빈발 패턴 마이닝 모델에서, 중요한 희귀 아이템이 포함된 패턴을 마이닝 하기 위해서는 낮은 최소 임계치를 설정해야 한다. 그러나 너무 낮은 최소 임계치는 의미 없는 아이템들을 포함하는 수많은 패턴을 야기한다. 반대로 높은 최소 임계치는 희귀 아이템이 포함된 패턴을 마이닝 하지 못하는 희귀 아이템 문제라 불리는 딜레마가 발생한다. 이러한 문제의 해결을 위한 초기 연구들은 아이템 빈도수에 따라 데이터를 몇 개의 블록으로 분할하거나 관련 희귀 아이템들을 하나의 그룹으로 만드는 방법을 사용한 근사적 접근법을 제안하였다. 그러나 이러한 기법들은 근사적 방법의 적용에 의해 모든 희귀 패턴을 포함한 빈발 패턴을 마이닝 하지 못한다. 다중 최소 임계치를 고려한 패턴 마이닝 모델은 아이템들의 개별적인 특성을 반영하여 희귀 아이템 문제를 해결하기 위해 제안되었다. 다중 최소 임계치 기반의 빈발 패턴 마이닝 모델에서 각 아이템은 MIS (Minimum Item Support)라고 불리는 개별 최소 임계치를 가지며, 아이템들의 데이터베이스 내 빈도수를 기반으로 계산된다. 다중 최소 임계치 모델은 MIS를 통해 수많은 의미 없는 패턴을 생성하지 않고도 손실 없이 모든 희귀 빈발 패턴을 찾아낸다. 한편, 빈발 패턴을 마이닝 하는 과정에서 후보 패턴들이 생성되며, 단일 최소 임계치 모델에서는 각 후보 패턴의 빈도수가 유일한 최소 임계치와 비교된다. 따라서, 희귀 아이템 문제가 발생할 뿐만 아니라 후보 패턴을 구성하는 아이템들의 특성이 고려되지 않는다. 다중 최소 임계치 모델에서는 이 문제를 다루기 위해 후보 패턴을 구성하는 아이템들의 MIS 값 중에서 가장 작은 MIS 값을 해당 후보 패턴의 최소 임계치로 설정하여 패턴 내 아이템들의 특성을 반영한다. 이를 적용하여 효율적으로 희귀 빈발 패턴을 마이닝 하기 위해 트리 구조 기반의 알고리즘은 빈도수 내림차순으로 트리 내 아이템들을 정렬하는 단일 최소 임계치 모델과는 달리 MIS 내림차순으로 아이템들을 정렬하여 마이닝을 수행한다. 본 논문에서는 다중 최소 임계치 기반의 빈발 패턴 마이닝 알고리즘에 대한 특성을 살펴보고, 일반 단일 임계치 기반 알고리즘과의 성능평가를 수행한다. 성능평가는 실행 속도, 메모리 사용량, 그리고 확장성의 관점에서 수행된다. 성능평가 결과, 다중 최소 임계치 기반의 빈발 패턴 마이닝 알고리즘은 희귀 빈발 패턴을 포함한 모든 빈발 패턴을 단일 임계치 기반의 빈발 패턴 마이닝 알고리즘보다 더 빠른 속도로 마이닝 하였으며, 각 아이템의 최소 임계치 정보를 위한 추가적인 메모리를 필요로 하였다. 또한, 비교 알고리즘들은 좋은 확장성 결과를 보였다.

The Law amending the Conflict of Laws Act of the Republic of Korea ("Korea"), which had taken two years to prepare, was promulgated on April 7, 2001 and finally took effect as of July 1, 2001. Accordingly, the old earlier Conflict of Laws Act which was called "Seoboesabeop" in Korean ("Prior Act"Old Act) was replaced by the new Conflict of Laws Act called "Gukjesabeop" in Korean ("New Act"). In fact the Old Act Prior Act was promulgated in 1962, but it was regarded as outdated from the moment of its promulgation. However, since the Old Act because it was modeled after the chapter of the Private International Law of the Einfuehrungsgesetz zum Buergerlichen Gesetzbuch (EGBGB) of the Federal Republic of Germany ("German PIL") and the Japanese Private International Law ("Japanese PIL") which had been promulgated toward the end of the 19th century., the Old Act was viewed as outdated from the moment of its promulgation. As a result of the drastic change of the environment for international trade of which that has taken took place in parallel with the global information technology revolution on a global basis, the scope of issues to be addressed which should be resolved by the conflict of laws principles has been remarkably expanded, and various new issues of an entirely which are quite new in its type and nature have arisen been raised. In the field of conflict of laws in its narrow sense, a revolution or crisis of the traditional conflict of laws has been brought about by the advent in the United States rise of a the new methodology for of the conflict of laws, of the United States of America and in the process of overcoming the such crisis the conflict of laws of the European continent has undergone substantial changes such as the diversification of the connecting principles, the expansion of the principle of party autonomy and the consideration of the value of the substantive law to protect socio-economically weaker parties of. The Prior Act, which was based on However, with the mechanical connecting principles and contained various outdated the inappropriate provisions, the Old Act could not cope with the issues raised by the internationalization and globalization of the Korean society. Furthermore In addition, the Old Act Prior Act was regarded as insufficient in that it lacked rules on international jurisdiction to adjudicate, or international adjudicatory jurisdiction, whereas the expectation of the public was that the Conflict of Laws a Act should function as the "Basic Law of the International Legal Relationships"encompassing rules on international jurisdiction given the increase of international disputes. Furthermore the private international law has also attracted more attention from the Korean At the beginning of the new Millennium, thanks to the promulgation of the New Act, I believe that Korea has succeeded in achieving the modest goal of reflecting in the its codification substantial parts of the major developments of the private international law which the leading advanced continental European countries had achieved during the last century. The New Act has followed the approach of the traditional conflict of laws of the European continent. It is a product of the efforts to eliminate the then existing problems of the Prior Old Act and to adapt the Korean private international law regime to the standard of international conventions and national laws of advanced countries. Unlike the Prior Old Act which was heavily dependent upon the prior Japanese PIL and the prior German PIL, the New Act has been prepared by taking into full account the Rome Convention, the Swiss PIL, the new German PIL which took effect in 1986 and various conventions adopted by the Hague Conference. Therefore, the New Act has substantially reduced dependence upon the Japanese PIL and the German PIL, and has gained relatively greater universal validity. The fact that the New Act expressly declares that the determination of international jurisdiction is a matter of conflict of laws is a clear sign that it has departed from the German tradition which confines the conflict of laws principles to choice of laws rules, and moved toward a broader and more practical approach widely accepted in the area of conflict of laws. It is hoped, and I am personally confident, that the New Act will be able to achieve its intended objectives in the 21st century as the basic law for the ever-increasing legal relationships with a foreign element.

Although it has been well known that ventricular fibrillation is the most important complication during hypothermia, much investigation has failed to show the exact nature of the etiology of ventricular fibrillation. Recently, there has been considerable research on the relationship between sympathetic activity and ventricular fibrillation under hypothermia. Cardiac muscle normally contains a certain amount of norepinephrine and the dramatic effect of this catecholamines on the cardiac muscle is well documented. It is, therefore, conceivable that cardiac catecholamines might exert an influence on the susceptibility of heart muscle to tachycardia, ventricular fibrillation and arrhythmia, under hypothermia. Hypothermia itself is stress enough to increase tonus of sympatheticoadrenal system. The normal heart is supplied by an autonomic innervation and is subjected to action of circulating catecholamines which may be released from the heart. If the reaction of the heart associated with a variable amount of cardiac catecholamines is. permitted to occur in the induction of hypothermia, the action of this agent on the heart has not to be differentiated from the direct effects of cooling. The studies presented in this paper were designed to provide further information about the cardio-physiological effects of reduced body temperature, with special reference to the role of catecholamines in ventricular fibrillation. Healthy cats, weighing about 3 kg, were anesthetized with pentobarbital(30 mg/kg) intraperitoneally. The trachea was intubated and the endotracheal tube was connected to a C.F. Palmer type A.C. respirator. Hypothermia was induced by immersing the cat into a ice water tub and the rate of body temperature lowering was $1^{\circ}C$ per 5 to 8 min. Esophageal temperature and ECG (Lead II) were simultaneously monitored. In some cases the blood pH and serum sodium and potassium were estimated before the experiment. After the experiment the animals were killed and the hearts were excised. The catecholamines content of the cardiac muscle was measured by the method of Shore and Olin (1958). The results obtained are summarized as follows. 1) In control animal the heart rate was slowed as the temperature fell and the average pulse rates of eight animals were read 94/min at $31^{\circ}C$, 70/min at $27^{\circ}C$ and 43/min at $23^{\circ}C$ if esophageal temperature. Ventricular fibrillation was occurred with no exception at a mean temperature of $20.3^{\circ}C(21-l9^{\circ}C)$. The electrocardiogram revealed abnormal P waves in each progressive cooling of the heart. there was, ultimately, a marked delay in the P-R interval, QRS complex and Q-T interval. Inversion of the T waves was characteristic of all animals. The catecholamines content of the heart muscle excised immediately after the occurrence of ventricular fibrillation was about thirty percent lower than that of the pre-hypothermic heart, that is, $1.0\;{\mu}g/g$ wet weight compared to the prehypothermic value of $1.41\;{\mu}g/g$ wet weight. The changes of blood pH, serum sodium and potassium concentration were not remarkable. 2) By the adrenergic receptor blocking agent, DCI(2-3 mg/kg), given intramuscularly thirty minutes before hypothermia, ventricular fibrillation did not occur in one of five animals when their body temperature was reduced even to $16^{\circ}C$. These animals succumbed at that low temperature, and the changes of heart rate and loss of myocardial catecholamines after hypothermia were similar to those of normal animals. The actual effect of DCI preventing the ventricular fibrillation is not predictable. 3) Administration of reserpine(1 mg/kg, i.m.) 24 hours Prior to hypothermia disclosed reduced incidence of ventricular fibrillation, that is, six of the nine animals went into fibrillation at an average temperature of $19.6^{\circ}C$. By reserpine myocardial catecholamines content dropped to $0.045\;{\mu}g/g$ wet weight. 4) Bretylium pretreatment(20 mg/kg, i.m.), which blocks the release of catecholamines, Prevented the ventricular fibrillation under hypothermia in four of the eight cats. The pulse rate, however, was approximately the same as control and in some cases was rather slower. 5) Six cats treated with norepinephrine(2 mg/kg, i.m.) or DOPA(50 mg/kg) and tranylcypromine(10 mg/kg), which tab teen proved to cause significant increase in the catecholamines content of the heart muscle, showed ventricular fibrillation in all animals under hypothermia at average temperature of $21.6^{\circ}C$ and the pulse rate increased remarkably as compared with that of normal. Catecholamines content of cardiac muscle of these animals markedly decreased after hypothermia but higher than control animals. 6) The functional refractory periods of isolated rabbit atria, determined by the paired stimulus technique, was markedly shortened by administration of epinephrine, norepinephrine and isoproterenol. 7) Adrenergic beta-blocking agents, such as pronethalol, propranolol and sotalol(MJ-1999), inhibited completely the shortening of refractory period induced by norepinephrine. 8) Pretreatment with either phenoxftenbamine or phentolamine, an adrenergic alphatlocking agent, did not modify the decrease in refractory period induced by norepinephrine. From the above experiment it is possible to conclude that catecholamines play an important role in producing ventricular fibrillation under hypothermia. The shortening of the refractorf period of cardiac muscle induced by catecholamines mar be considered as a partial factor in producing ventriculr fibrillaton and to be mediated by beta-adrenergic receptor.

The pathogenesis of atherosclerosis can not be summarized as a single process. Lipid infiltration hypothesis and endothelial injury hypothesis have been proposed and investigated. Recent developments show that there are many points of potential interactions between them and that they can actually be regarded as two phases of a single, unifying hypothesis. Among the many risk factors of atherosclerosis, plasma homocysteine and lipoprotein(a) draw a considerable interest because they are independent indicators of atherogenicity. Triglyceride (TG)-rich lipoproteins (chylomicron and VLDL) are not considered to be atherogenic but they are related to the metabolism of HDL cholesterol and indirectly related to coronary heart disease (CHD). LDL can of itself be atherogenic but the oxidative products of this lipoprotein are more detrimental. HDL cholesterol has been considered to be a favorable cholesterol. The so-called 'causalist view' claims that HDL traps excess cholesterol from cellular membranes and transfers it to TG-rich lipoproteins that are subsequently removed by hepatic receptors. In the so-called 'noncausalist view', HDL does not interfere directly with cholesterol deposition in the arterial wall but instead reflects he metabolism of TG-rich lipoproteins and their conversion to atherogenic remnants. Approximately 70-80% of the human population shows an effective feedback control mechanism in cholesterol homeostasis. Type of dietary fat has a significant effect on the lipoprotein cholesterol metabolism and atherosclerosis. Generally, saturated fatty acids elevate and PUFA lower serum cholesterol, whereas MUFA have no specific effect. EPA and DHA inhibit the synthesis of TG, VLDL and LDL, and may have favourable effects on some of the risk factors. Phospholipids, particularly lecithin, have an antiatherosclerotic effect. Essential phospholipids (EPL) may enhance the formation of polyunsaturated cholesteryl ester (CE) which is less sclerotic and more easily dispersed via enhanced hydrolysis of CE in the arterial wall. Also, neutral fecal steroid elimination may be enhanced and cholesterol absorption reduced following EPL treatment. Antioxidants protect lipoproteins from oxidation, and cells from the injury of toxic, oxidized LDL. The rationale for lowering of serum cholesterol is the strong association between elevation of plasma or serum cholesterol and CHD. Cholesterol-lowing, especially LDL cholesterol, to the target level could be achieved using diet and combination of drug therapy. Information on the link between cholesterol and CHD has decreased egg consumption by 16-25%. Some clinical studies have indicated that dietary cholesterol and egg have a significant hypercholesterolemic effect, while others have indicated no effect. These studies differed in the use of purified cholesterol or cholesterol in eggs, in the range of baseline and challenge cholesterol levels, in the quality and quantity of concomitant dietary fat, in the study population demographics and initial serum cholesterol levels, and clinical settings. Cholesterol content of eggs varies to a certain extent depending on the age, breed and diet of hens. However, egg yolk cholesterol level is very resistant to change because of the particular mechanism involved in yolk formation. Egg yolk contains a factor of factors responsible for accelerated cholesterol metabolism and excretion compared with crystalline cholesterol. One of these factors could be egg lecithin. Egg lecithin may not be as effective as soybean lecithin in lowering serum cholesterol level due probably to the differences of fatty acid composition. However, egg lecithin may have positive effects in hypercholesterolemia by increasing serum HDL level and excretion of fecal cholesterol. The association of serum cholesterol with egg consumption has been widely studied. When the basal or control diet contained little or no cholesterol, consumption of 1 or 2 eggs daily increased the concentration of plasma cholesterol, whereas that of the normolipemic persons on a normal diet was not significantly influenced by consuming 2 to 3 eggs daily. At higher levels of egg consumption, the concentration of HDL tends to increase as well as LDL. There exist hyper-and hypo-responders to dietary (egg) cholesterol. Identifying individuals in both categories would be useful from the point of view of nutrition guidelines. Dietary modification of fatty acid composition has been pursued as a viable method of modifying fat composition of eggs and adding value to eggs. In many cases beneficial effects of PUFA enriched eggs have been demonstrated. Generally, consumption of n-3 fatty acids enriched eggs lowered the concentration of plasma TG and total cholesterol compared to the consumption of regular eggs. Due to the highly oxidative nature of PUFA, stability of this fat is essential. The implication of hepatic lipid accumulation which was observed in hens fed on fish oils should be explored. Nutritional manipulations, such as supplementation with iodine, inhibitors of cholesterol biosynthesis, garlic products, amino acids and high fibre ingredients, have met a limited success in lowering egg cholesterol.

The present study is purported to provide a basic information to be utilized by nurses to care and attend effectively for patients nearing the moment of death. Therefore, the primary purpose of the study has been placed upon grasping an understanding of the trends of death in general. For this purpose: 1. By utilizing the schneidman questionnaire, the trend of death has been categorized by 6 parts and analyzed. 2. A search has been conducted to find out dying patient's needs, nurse's attitudes viewed by the patient, and nurse attitudes to dying patient. The followings are itemized results of analysis: 1. Analysis by the schneidman questionnaire. (1) In general concepts of death. the first sighting of the occurrence of death was experienced upon strangers, grandfather and great grandfather. The death is openly discussed among people of all ages and sex. Ages in which the death is mostly feared were from 12 to well over 70 yews old that are evenly distributed regardless of difference in age. (2) As to the attitudes toward death the occurrence of death to most closely associated person influenced most upon the attitude of their own termination of lives. Among the reading materials, the maximum influence was effected by the Bible. In terms of religion, the thoughts of death were Influenced by religions education in case of the believers of the western religions (36%), and by their own health and physical conditions in case of the believers in the oriental religions (35%). In case of non-believer, their attitude toward death were largely determined through their own thinking meditation (45%). People aged 20 or thereunder revealed that they wished to know the day of their own death to be occurred (58%). However, the older the less thor wanted to know. (3) As to the choosing the time of death, 57% preferred senility, and 30% preferred the time in mediately following the prime period of their lives in general. In terms of religion, 85% of the believer in the oriental religion preferred senility, and 67% in the western religion, 58% in others, Therefore. the desiring of their lives to be terminated in earlier stage, not by the natural senility. sequenced as follows : Others, western religions and oriental religions. (4) Referring to the disposal of the corpse under the assumption that it had already occurred, majority desired the burial system. There has been seen a slight tendency to consider the importance of holding funeral services for the sake of survivors. Concerning the life insurance policy, it showed that the nurse had less belief in it than the patient (5) Upon the subject of life-after-death. religion wise, 72% of western religion believers preferred to have an existence of life-after-death: Among the believers of oriental regions, 35% desired this category, 30% did not mind either way. and 35% did not desire the existence of such a life-after-death. In others, 53% did not mind whether or not such a life existed. (6) In general, serious thoughts were not being attended to the commitment of suicide. 37% emphasized that such an act should be prevented. However, 30% insisted that such commitment should not be bothered, and that society possesses no right to prevented it. More male wished to commit suicide (13%) than females (9%). 2. Nurse's attitudes toward terminal patients and patient's needs. In the instance where the patient realized that their death is imminent, most of them showed desire to discuses mainly on the problems of life. When faced a situation of this nature, it is revealed that 40% of nurses could not furnish appropriate care for them.

Metropolitan rapid transit system plays an essential role in the public transportation system of any large city, and its managing agency is usually charged with the responsibility of storing and managing the design drawings of the system. The drawings are important and historically valuable documents that must be kept permanently because they contain comprehensive data that is used to manage and maintain the system. However, no study has been performed in Korea on how well agencies are preserving and managing these records. Seoul Metropolitan Rapid Transit Corporation(SMRT) is the managing agency established by the city of Seoul to operate subway lines 5, 6, 7, and 8 more efficiently to serve its citizens. By the Act on Records Management in Public Institutions(ARMPI), SMRT should establish a records center to manage its records. Furthermore, all drawings produced by SMRT and other third party entities should be in compliance with the Act. However, SMRT, as a form of local public corporation, can establish a records center by its own way. Accordingly, the National Archives & Records Service(NARS) has very little control over SMRT. Therefore, the purpose of this study is to research and analyze the present state of storage and management of the drawings of metropolitan rapid transit in SMRT and is to find a desirable method of preservation and management for drawings of metropolitan rapid transit. In the process of the study, it was found that a records center is being considered to manage only general official documents and not to manage the drawings as required by ARMPI. SMRT does not have a records center, and the environment of management on the drawings is very poor. Although there is a plan to develop a new management system for the drawings, it will be non-compliant of ARMPI. What's happening at SMRT does not reflect the state of all other cities' metropolitan rapid transit records management systems, but the state of creation of records center of local public corporation is the almost same state as SMRT. There should be continuous education and many studies conducted in order to manage the drawings of metropolitan rapid transit efficiently by records management system. This study proposes a records center based on both professional records centers and union records centers. Although metropolitan rapid transit is constructed and managed by each local public corporation, the overall characteristics and processes of metropolitan rapid transit projects are similar in nature. In consideration of huge quantity, complexity and specialty of drawings produced and used during construction and operation of metropolitan rapid transit, and overlap of each local public corporation's effort and cost of the storage and management of the drawings, they need to be managed in a professional and united way. As an example of professional records center, there is the National Personnel Records Center(NPRC) in St. Louis, Missouri. NPRC is one of the National Archives and Records Administration's largest operations and a central repository of personnel-related records on former and present federal employees and the military. It provides extensive information to government agencies, military veterans, former federal employees, family members, as well as researchers and historians. As an example of union records center, there is the Chinese Union Dangansil. It was established by several institutions and organizations, so united management of records can be performed and human efforts and facilities can be saved. We should establish a professional and united records center which manages drawings of metropolitan rapid transit and provides service to researchers and the public as well as members of the related institutions. This study can be an impetus to improve interest on management of not only drawings of metropolitan rapid transit but also drawings of various public facilities.

The purpose of this research lies in presenting logical viability for the measures that curtail access to lewd Internet contents by middle school students amidst the reality in which lewd contents are circulated freely through the Internet, a medium that the middle school students find most easy to access. In order to establish right form of awareness towards sex, this research identified the ways they access the lewd Internet contents, their reaction after the exposure to those contents, their knowledge of sex, their concerns regarding sex and their accessibility to sexual activities in order to conduct a comparative analysis on the relationship between lewd Internet contents and their awareness of sex. First, realities of accessing lewd Internet contents and reactions according to the demographics of middle school students There isa significant difference in the experience of accessing lewd Internet contents in terms of gender. Mostly, male students tend to access the contents more. As for the way they access the lewd Internet contents, both male and female students replied that they access through spam mail of lewd nature. Thus, measures to address this problem are needed urgently. As to when they first accessed the lewd contents, most of the research subjects replied that they accessed either in elementary school period or in the early middle school period. This shows that most of the students got exposed to lewd contents even before they could establish positive, correct awareness of sex. Thus, there is a risk that they may formulate wrong kind of sexual awareness. Accordingly, it is necessary to develop measures through focused sex education. Students are divided into two groups according to the time they spend on the contents averagely: those who spend over one hour and those who spend less than an hour on the lewd contents. If the students spending longer hours are not to be checked and properly guided, it may lead to increasing cases of sexual delinquencies due to their wrongly formed awareness of sex. When the question of existence(non-existence) of guardian was addressed, students with both parents tend to access the lewd Internet contents in a more diverse manner and tend to access more compared to those students from single parent or no-parent families. Accordingly, guardians need to pay attention to how their children are using the Internet. Second, awareness of sex depending on the middle school students' demographics In case of sexual knowledge, middle school students shows relatively high level of knowledge. In particular, female students are found more knowledgeable than male students, and the students in upper years are more knowledgeable as well. As a result, this research recommends that the students in lower years should be guided with more basc and detailed information, while those in upper years need to be taught to form and express their own thoughts and attitudes and to build up independence on this matter. In case of worries about sex, both male and female students don't worry too much about it. However, male students are more concerned about sex than female students in a more diverse ways. As for the differences by academic year, concerns for sex increase, as students get older. Accordingly, sex education that helps establish sound perception of the opposite sex and that focuses on the etiquettes that one must adhere to at the presence of the opposite sex need to be conducted against middle school students. In case of accessibility to sex, male students manifest higher tendency than female students. As for the differences by academic year, those in the first and second years show higher accessibility than those in their third year. In general, younger students tend to be more open-minded toward sex. Accordingly, students in lower academic years need to undergo basic knowledge oriented sex education, whereas those in upper academic years need to undergo discussion centered sex education where they subject to questions regarding their attitude and opinion. Third, relationship between the reactions after the exposure to the lewd Internet contents and their awareness of sex As the frequency of contact with lewd Internet contents increases, awareness of sex increases as well. Thus, the lewd Internet contents contribute to the increase in students' concern for sex as well as increase in accessibility to sex, which eventually become barriers to students' establishment of a healthy perception of sex. Reactions to sex after the exposure to lewd Internet contents and awareness of sex indicate a significant correlation. However, negative correlation is manifested with knowledge of sex. Thus, it is possible to know that the greater access to lewd Internet contents does not necessarily translate into increase in knowledge of sex. However, the study showed there is a correlation between concerns for sex and the level of accessibility to sex. In more detail, the more reactions to the contents they show, the more concerns for sex they have and the more positively they take acceptability to sex. Moreover, it is necessary to develop necessary measures since textbooks today do not include measures needed to address the lewd Internet contents. Given the above findings, it is necessary to continue to complement structural measures in order to prevent easy access of lewd Internet contents by middle school students. Moreover, it is necessary to be considerate of the students so that they themselves can form a healthy Internet culture and grow up within positive framework for the sex education.

In spite of the great progress of the theory and skill of the Nursing Care & Medical area in relation to pregnancy, nurses in clinics face up to many challenges in maternity nursing care areas. The reason is that the mobility and mortality of mothers was sharply decreased and the unknown high-risk diseases of pregnancy woman in the past is made public. That's why it is difficult to meet the pregnancy woman in natural process from pregnancy to delivery in recently. Admission rooms are filled with high-risk pregnancy women. As a matter of fact, we have done nursing care into the surface symptoms and diseases of high-risk pregnancy women so far. We have been indifferent to a long period hospitalization, separation from family, and conflict of repeated examination. Therefore, it is widely spread to understand the emotional conflict experienced by high-risk pregnancy women and to need for nursing intervention to bring up about emotional support and the ability of perception in psychological crisis. Although the pregnancy woman judged in high-risk should carry out normal task of pregnancy, she have to be confronted with secondary risk situation. The health of self & fetus threatened by the risk situation could be decreased through care plan, but psychological stress increases. Therefore, the pregnancy brings into non-control state. It is important to ask that what the hospitalized pregnancy women in high-risk think of themselves status. Because misunderstanding or serious anxiety of themselves status put into mother and fetus in danger. And adaptation mode makes all the difference. I would like to consider how nurses could deal with this high-risk circumstances in the position of pregnancy woman on the basis of the above fact. This study uses phenomenological method to suggest the basis material for nurses to do nursing intervention in view of pregnancy woman. Because this method understands the nature of true life of pregnancy woman throughly. The phenomenological method is the sources to describe or explain affluently the process generated in confirmation areas and environment and is the application for readers to understand and recognize clinic reality and then apply this method to reasoning study place or other places. Specifically, the phenomenon study method, one of the phenomenological method, is applied. The use of that method is to describe and generalize the experience in environment exactly. The study of this study is as follows : Among 187 descriptive stamens from 8 study participants are classified into 42 theme cluster at the stage of the first analysis. Those theme is categorized into 8 sub-subjects such as anxiety of uncertainty, foreknowledge about risk circumstance, will power about overcome, unsettled feeling about hospital, relief, optimistic thought, family support, and indifferences. At the last stage of analysis, those things are categorized into 3 subjects. When high-risk pregnancy woman foretell the situation, they feel unsettlement about uncertainty and untrust feeling about hospital. But they are ease with family support and hospital support. On the other hand, they express indifferent 3-way structure response to the situation having will of overcome and exceeding optimistic thought. In those statements, the experience by pregnancy woman shows 3 respect subjects. 1. They are anxious of this situation and are in desperation and don't recognize their role to be carried out 2. They think of this situation as normal process of pregnancy and are not concerned that this can give themselves and fetus fatal damage. 3. The pregnancy women will never confront this situation. This study shows the pregnancy woman has anxiety and optimistic relief about the situation, and ignores and optimistic relief about the situation, and ignores many things. Therefore, nurses in clinic should give pregnancy woman knowledge and information about the high-risk and help them to deal with the situation spontaneously. High-risk pregnancy woman should have the care plan in respect of the right perception. And the nurse know that their support help out pregnancy woman overcome the crisis in this respect of the special nursing intervention.

본 연구는 초등학교 환경교육을 통해서 우리 자연자원의 소중함을 인식시키고, 실제 학교환경을 이용한 자생식물 교육을 위하여 제도적 교과서에서의 식물이용현황 및 학교현장의 녹지공간 현황, 자생식물 식재여부를 통하여 다음과 같은 결론을 도출할 수 있었다. 첫째, 향후 7차 교과 개정시에는 교과서에 자생식물에 대한 개념 및 훨씬 더 많은 자생식물이 그림이나 사전과 함께 실리며, 학생들이 접하기 힘든 어려운 식물들을 초기단계부터 교육하기 보다는 일상생활에서 늘 접할 수 있는 쉬운 가존의 소재들을 바탕으로 중기단계에서는 직접 실생활에서 응용되는 실용적 소재로 학생들에게 흥미를 유발하여 말기에는 희귀종, 어려운 식물 및 우리 자생식물을 '먹을 수 있는 식물', '나비와 벌이 모여드는 식물', '약으로 쓰이는 식물', '습지를 좋아하는 식물'들로 테마를 설정해 제시하는 단계별 방안이 모색되어져야 한다. 둘째, 현재의 학습원은 작물, 초화류 위주의 식물식재로 학생들에게 다양한 식물교육, 특히 자생식물 교육의 효과를 가지지 못하고 있다. 더욱이 교사와 학생들에 의해 식물이 식재되고, 관리되어지는 실습의 장으로써가 아닌 일부 교사, 또는 담당관리에 의해 조경수목 식재지의 일부로 관리되어지는 경우가 많음을 현황조사 결과 알 수 있었다. 학습원과 더불어 학교 녹지공간 전체의 배치, 식생의 층위구성, 자생식물의 식재수종 등에 변화가 요구된다. 학교환경을 효율적으로 이용하기 위한 방안으로 현재 조성되어 있는 학습원(재배원 교재원) 및 조경공간 등의 적극적인 활용과 비조성 학교에서의 학습원 조성을 위해 모델제시와 더불어 "어린이 자생식물 연구회", "우리꽃 가꾸기 모임", "1인(人) 한 나무 가꾸기" 등의 다양한 모임을 토대로 우리꽃 이름짓기 대회, 관찰일기 쓰기, 우리학교 자연이야기 신문 만들기 등의 다양한 프로그램 개발을 활성화하여 학교 내에서의 자생식물 실습교육을 유도한다. 향후 위 자료를 기초로 교사와 학생에 대한 식물교육 및 자생식물에 대한 향후 의식조사를 실시하여 현재 학교에서의 오염중심 환경교육에서 벗어나 자연과 접하며 실제 환경의 소중함을 체험할 수 있는 정확한 정보 및 다양한 자료를 통하여 생명의 소중함을 느끼게 하고, 환경 문제의 근본적인 해결을 위한 방안이 요구된다.
