This study was done for the purpose of investigating nursing students' health promotion behavior and health status and analyzing the relationship between health promotion behavior and health status. The subjects for this study were 249 nursing students obtained by a convenience sampleing from two Junior Colleges Located in Kangwon-do. The instruments used for this study were health promotion behavior scale developed by the researcher and modified Cornell Medical Index developed by Brodman, Erdmann, Lorge, Wolff & Broadbent. Data were collected from November 21 to December 10, 1994 by means of questionaire. The data were analyzed through the SPSS program by use of descriptive statistics, t-test, ANOVA and Pearson Correlation Coefficient. The results of the study were as follows; 1) The subject's degree of health promotion behavior was about middle level 2) When the relationships between health promotion behavior and their general characteristics were explored, economic status, importance of health & perceived health status were revealed to have significant differences. 3) The subject's health status was at slightly high level, therefore viewed their health as slightly good. 4) When the relationships between health status and their general characteristics were explored, age and perceived health status were revealed to have significant differences. 5) In regard to the relationship between health promotion behavior and health status, psychological health status correlated positively with health promotion behavior (r=.193, p=0.002) ; physical health status correlated positively with psychological health status (r=0.493, p=0.000). But, physical health status did not show a significant correlation with health promotion behavior. In conclusion, it is important for late adolescents including nursing students to lay the foundation for chronic disease prevention by promoting and maintaining healthy lifestyles. Many of the leading causes of disease are preventable, through changes in lifestyle. The need to increase individual awareness of relationships between lifestyle and health and to enhance knowledge regarding the long-term effects of negative health behaviors, is an important nursing strategy for health promotion.

The purpose of this study was to investigate the rate of pregnancy, abortion, delivery and contraceptive use and the relationship between the related factors and the early coitus among Korean teenagers. Method: The subjects of this study were 12,733 teenagers age 13-19 years in 7 major cities and 9 provinces in Korea. Data was collected from 2 Oct., to 28 Oct., 2000 and analyzed by using SPSS 10.0 Program. Results: The results showed pregnancy rate 4.5%, delivery rate 0.5%, abortion rate 0.4%. Adolescent girls who experienced coitus relatively went to vocational school, coeduaction school, night school in the general characteristics (p=0.000). Adolescent girls who experienced coitus tend to go to video room (18.5%), go the singing room (60.7%), the bar (54.8%), petting with the partner during the dates. There were overlapping juvenile delinquencies such as drinking (89.2%), pornography (65.3%), bond inhalation (2.7%), leaving homes (43.7%), smoking (14.5%), cyber sex (70.8%), phone sex (12.9%). Adolescent girls who experienced coitus were more suffering from Wangtta (26.1%) than who had not. They showed significant positive attitudes toward coitus; such as feeling of excitement (6.6%), nature (37.9%), beauty (8.7%). On the other hand, they had more guilty (2.8%) than the inexperienced (p=0.000). The main factors relating to early coitus were 'to confirm love' (46.9%), 'afraid of rejection' (32.2%). They think the benefits of coitus were 'more intimacy with boyfriends' (20.6%), 'satisfaction of curiosity' (16.8%). The losses on coitus were 'worry about pregnancy' (73.7%) and 'unability to refuse sexual contacts' (28.7%) Conclusion: It could be concluded that it is necessary to plan different sex education programs according to general characteristics and delinquency behaviors of teenage girls in Korea.

Since 1950s' we have come to take a deep interest in matrimonial communication as the theories of family therapy though communication came to extend. In the rapid changing modem society, especially, the dysfunctional aspect of the communication rather than functional one tends to grow high because married couples who suffer from isolation and solitary in social life want to satisfy their unfilled desire through matrimonial communication and apt to be hurt easily by their attitudes and behaviors. When these discrepancies in dysfunctional aspect take place repeatedly, the conflict between married couple which is bad in their psychological effects go from bad to worse and influence their somatic symptoms. This study was attempted to examine the relationship between dysfunctional communication patterns of married couple and complaint degree of housewives psychosomatic symptoms and to use as basic materials focusing on nursing system centered around family, which aims to reach the family centered culture of Korea. To gain the aims, some surveys were peformed at Seoul, Chinju and some areas of Kyeongki province, and the study materials were collected from 70 wives who were encountered by 12 pastrolists majoring in clinical pastrol of ‘Y’ Theological Graduate School and from neurotic patients of those who visited the internal Medicine depts of 1 university hospital and 4 hospitals ‘J’ city, among whom they used dysfunctional communication pattern in their married life. And data collection was peformed from Feb. 22, 1988 to April 22. In the survey, four types of dysfunctional communication presented by Song Sung-Ja were used as the survey tool. And the complaint degree on Psychosomatic symptoms was measured by the classification according to the complaint degree of housewives's psychosomatic symptoms through pretest after content validity, in which the housewives who dysfunctional communication wert surveyed. To learn matrimonial Communication patterns that have an effect on housewives psychosomatic symptoms in the surveyed.

Accordingly the number of smart-phone-based malicious codes is also increasing and their techniques for malicio us purpose are getting more clever and evolved. Among them, the malicious codes related to Android take the major portion and it can be estimated that they are based on open source so that the access to the system is easy. Intent is a technique to support the communication between application's components by transmitting message subjects in Android. Intent provides convenience to developers, but it can be utilized as security vulnerability that allows the developer with a malicious purpose to control the system as intended. The vulnerability of intent security is that personal information can be accessed using discretionally its proper function given to application and smart phone's functions can be maliciously controlled. This paper improves with the Intent security vulnerability caused by the smart phone users' discretional use of custom kernel. Lastly, it verifies the malicious behaviors in the process of installing an application and suggests a technique to watch the Intent security vulnerability in realtime after its installation.

This study attempts to understand women's underwear culture in the Later Chosun Dynasty, by investigating the kinds and constructions of them, which formed bulky and puffed silhouette of the lower half of the body. In the middle 17th century in Chosun, Confucianism settled down as fundamental idea of society, while whole country achieved considerable economic growth. As a result for upperclass women, female virtues was demanded more than any other period in Chosun. On the other hand, lower-class women including Kisaengs, had more freedom on their clothing behaviors. According to the literature on women's dress institutions and restrictions of the extravagance, the use of kinds of high-quality silk and false hair was criticized, compared to women's clothes in China. From this, one can see the luxury and affluence of women's clothes at that time, which also reflected in luxurious underclothes. Also, the movement of class, by economic development, led to changes in the costumes of middle-to-lower class women, relaxing restrictions on clothes. Underclothes included Bosomband(가슴띠; long sashes for bosom to wrap), Sokjucksam(속적삼), and Sokchogori(속저고리; Korean blouse, worn under the chogori) for upper garment, and Darisokkok(다리속곳; basic underwear like the panty), Soksokkot(속속곳; underwear paji to be wide of hem), Sokpaji(속바지;trouser front and back opening), Tansokkok(단속곳; large size underwear like Soksokkot), Noronpaji(너른바지; paji like the skirt or paji bulky than tansokkot,), Mujigi무지기; tiered skirt for underwear), and Daeshumchi'ma(대슘치마; Korean underskirt, shape hem as a pad into form) for lower clothes.

QoS monitoring is a kind of real-time systems which allows each level of the system to track the ongoing QoS levels achieved by the lower network layers. For these systems, real-time communications between corresponding transport protocol objects is essential for their correct behavior. When two or more entities are employed to perform a certain task as in the case of communication protocols, the capability to do so is called interoperability and considered as the essential aspect of correctness of communication systems. This paper describes a formal approach on modeling and interoperability test case generation of a real-time QoS monitoring protocol. For this, we specify the behavior of flow monitoring of transport layer QoS protocol, i.e., METS protocol, which is proposed to address QoS from an end-to-end's point of view, based on QoS architecture model which includes ATM net work in lower layers. We use a real-time Input/Output finite State Machine to model the behavior of real-time flow monitoring over time. From the modeled real-time I/OFSM, we generate interoperability test cases to check the correctness of METS protocol's flow monitoring behaviors for two end systems. A new approach to efficient interoperability testing is described and the method of interoperability test cases generation is shown with the example of METS protocol's flow monitoring. The current TTCN is not appropriate for testing real-time and multimedia systems. Because test events in TTCN are for message-based system and not for stream-based systems, the real-time in TTCN can only be approximated. This paper also proposes the notation of real-time Abstract Test Suite by means of real-time extension of TTCN. This approach gives the advantages that only a few syntactical changes are necessary, and TTCN and real-time TTCN are compatible. This formal approach on interoperability testing can be applied to the real-time protocols related to IMT-2000, B-ISDN and real-time systems.

Injury has now replaced disease as the biggest single cause of death in children after their first birthday. Each day child dies from preventable, unintentional injury and the medical cost of these injury is increasing remarkably. It is necessary to develope injury prevention models to explain, predict, manage, evaluate and analyze the information about accident. The purpose of this paper is, firstly, to investigate parent's actions regarding safety measures at home and secondly, to identify the influencing factors of parents' safety behaviors. The selection of such factors is guided by the theoretical framework of the Pender's Health Promotion Model. Method ; The questionnaire was developed on the basis of other investigations, through pilot testing, peer review, and review by field health workers. The questionnaire was completed by 231 mothers of young children. Data was collected between April and May 2002. Variable Use of three different domains of safety behavior, safety habits, supervision and perception of safety devices, were listed. Mothers were self reported on internal locus of control, mother & child relationships, and marital intimacy. Also the elements of the Health Promotion Model: perceived benefit, barrier, threat, and self-efficacy, were surveyed. Results & discussion The results indicate that most parents take considerable action to reduce household hazards. The constructs derived from the Model were statistically significant differences for a small part of the variables on parental behavior to reduce hazards in the home, such as age, education, economic status, self-efficacy, perceived benefit, internal locus of control. Future studies ought to include social influences, such as expectations, perceived norms, knowledge, and child-related variables, relevant to parental safety measures in their home.

Objectives : Prevalence of night eating habit associated with substance use and obesity is increasing rapidly in children and adolescents. Further, staying up late and eating snacks late at night were known as leading health risk behaviors for children, suggesting the potential adverse effect of night-eating habit on children. However, only few reports had been issued on the effect of night-eating habit on gastrointestinal symptom and SUI-TAI(水滯) symptom of children. Therefore, we aimed to investigate clinical characteristics of children by night-eating symptom status. Methods : Parents were asked to give a detailed answer to a systemized medical history questionnaire concerning night-eating habit, gastrointestinal symptom and SUI-TAI symptom of their children. Medical records of 28 children treated in the Department of Pediatrics, Hospital of Oriental Medicine, were the subject of this study. Clinical characteristics of two groups of children who with no night-eating habit and frequent night-eating group(eating at night more than 3 times per week) were analysed. In addition, the correlation analysis between clinical characteristics were performed. Results : Children with frequent night-eating habit(n=7, more than 3 days of night-eating a week) were observed to have more aggravated gastrointestinal symptom and SUI-TAI symptom compared with those without night-eating habit(n=13). In parallel, the association of gastrointestinal symptom and SUI-TAI symptom was demonstrated(n=28). Conclusions : It is notable that deranged gastrointestinal function and aggravated SUI-TAI symptom were observed among children generally regarded as healthy. Therefore, endeavors to correct night-eating habit as well as to treat aggravated gastrointestinal and SUI-TAI symptoms are needed for the promotion of health of children.

The conversion of fibroblasts into osteoblasts requires the activation of key signaling pathways, including the BMP pathway. Although Runx2 is known to be a component of the BMP pathway, the combination of Runx2 and BMP2 has not yet been examined with respect to the conversion of fibroblasts into osteoblasts. Here, human ligamentum flavum (LF) fibroblast-like cells from six patients were tested for their conversion into osteoblasts using adenoviruses expressing Runx2 or BMP2. The forced expression of Runx2 or BMP2 in primary cultured LF cells resulted in a variety of proliferation and differentiation behaviors. Combined treatment of BMP2 plus Runx2 resulted in better osteoblastic differentiation than treatment with either component alone. These results indicate that the Runx2 and BMP2 pathways possess both common and independent target genes. Collectively, Runx2 plus BMP2 mediated efficient conversion of fibroblast-like LF cells into osteoblast-like cells, suggesting the possible use of these components for clinical applications such as spinal fusion.

Mechanical properties of static and dynamic behavior became important since the use of conical composite tubes in large structures such as aerospace, planes, and submarines as well as leisure goods such as bicycle frames, fishing rods, and golf shafts. In the past, the mechanical property prediction model for static behavior was studied using vibration, bending, and buckling. But there is a need to study how fiber orientation error affects mechanical properties of conical composite structure because the model assumes constant fiber orientation angle. The purpose of this study is to derive an equation that can predict the static behavior of conical composite tube for bicycle frames by considering fiber orientation error with respect to various design parameters.
