The purpose of this study was to confirm the classification of nursing activity and to analyze the time of nursing workload in a new open hospital. The data were collected from 20 nurses working in 6 general nursing units by 4 trained observers. The tools used for this study were an observation recording sheet and a classification sheet of nursing activity. The classification sheet was constructed to be adaptable to each hospital system based on the instrument described in the literature. The results of the study are as follows : The direct nursing activities consisted of 6 sections, 33 subsections and the indirect nursing activities consisted of 14 sections, 53 subsections. The direct nursing activities included medication, measuring and observation, care of therapies, care of physical comfort, laboratory and treatment. The indirect nursing activities included preparation of medical utensils, collection of information and assessment, recording, phone communication, professional interaction related to patients, personal time, assigning work to staff, patient eaucation and training, interaction with lab, transfer of administration of utensils, checking physician's order, dietary service, management of pollution and contagion, guide direction. Nurses spent 127.6min for direct nursing activity during day duty. It was 24.5% of total nursing activity. Within that activity medication had the highest percentage of time(40.09%), followed by communication and education with patient(24.76%), measuring and observation (16.93%), laboratory and treatment (12.85%), care of therapies(3.21%) and care of physical comfort (2.16%). The time breakdown for indirect nursing activities is as follows ; the preparation of medical utensils 22.3%, collection of information and assessment 20.29%, recording 20.27%, phone communication 8.14%, professional interaction related to patients 7.33%, personal time 7.24%, with the remaining timeshared by staffing, patient education and training, interaction with lab, transfer of administration of utensils, checking physician's order, dietary service, management of pollution and contagion, guide direction. In the analysis of the relationships between the working time and the work allocation characters of the nurses(including nurse's experiences. nurse-patients ratio, nurse-rooms ratio, and character of nursing unit) ; There were no significant differences in direct-indirect nursing times between nurse's career years. There was significant difference in direct nursing time between assigned patient numbers. The nurses assigned larger number of patients spent significantly more time in direct nursing care than that of the smaller. On the other hand, there was no significant difference in indirect nursing workload between the assigned patient numbers. There were no significant differences in direct-indirect nursing time between an allocated patient's room numbers. There was significant difference in working time between working places. The nurse in the medical unit spent more time in direct nursing care than her counterpart in the surgical unit. However there was no difference in direct nursing time between two groups. The study results indicate that nurses spent less time in the direct nursing care than in the previous studies even though the hospital system has been modernized. On the other hand they spent much more time for the coordinating role within the interdisciplinary team and for the overlapping paperwork. Therefore it is recommended that patient oriented job description and more efficient usage of modernized utilities be made.

It is the purpose of this study to address how to manage the urban vegitation using the concept of Urban Forestry which is relatively new to Korea. When we consider the Urban Forestry as a science, We should understand it interdisciplinary subject which includes Forestry, Horticulture, Urban Planning, Landscape Design, Landuse Planning, Business and Humanities. It may say that people and tree are the fundermental components of Urban Forestry. So there are two ways of Urban Forestry Applications-How people care for trees and How trees care for People-. For the application, this study places the focus on the monetary valuation, tree inventory system and traditional forestry application to urban forest management. Pubic Relation, Communication, Ordinances and Budget are also mentioned as a part of Urban Forestry Policy. Monetary valuation of trees and forests is very important for the proper cognition of their real value. So that, they may be equated and weighed against conflicting uses which would cause to be removed or severely mutilated. A tree inventory system which is the essential part of urban tree management can provide the pertinent information about the present condition of urban tree resource. It may aid in reducing the subjectivity of tree management decisions and stimulate them to be made rapidly and can help reduce potential municipal liability by identifying serious problems in time for corrective maintenance practices to be applied for the maximize community benefits and minimimize public nuisances or hazards. Managers can derive the information from the inventory and use it for the various management plan. When we see the structure of tree inventory system as one of the data base management system, Computer is the best equipment for the efficient management plan. Public relation and communication is also important factors to care the people for urban vegetation management. Volunteer management system is a good example for the public relation and communication. Those skills are need to develop for using the priceless, valuable human resources. Budget holds the key to the execution of Urban Forestry. Good inventory can provide for efficient budgeting stratiges through it's scientific analysis for the way of maximum benefits and minimum costs. Forest can be play a vital role for the aesthetic improvement and recreation in the city. This study suggests that the traditional sivicultural application not only improve the quality of scenic beauty and recreation but also the products of timber. So it is more needed to study for strong and scientific application to urban forest management.

IPSec(Internet Protocol Security)은 IP(Internet Protocol)계층에서 패킷에 대해 무결성(Integrity), 기밀성(Confidentiality), 인증(Authentication), 접근제어(Access Control) 등의 보안 서비스를 제공하는 국제표준 프로토콜이다. 하지만 IPSec의 지나친 복잡성으로 시스템 구현이나 상호 호환의 어려움을 겪고 있는데, 이는 IKE의 복잡성에서 기인한다. 양단간의 신뢰성 있는 암호화키의 관리와 분배를 위해 사용되는 IKEv1(Internet Key Exchange Version 1)은 시스템의 복잡하고 DoS(Denial of Service) 공격에 취약하며 호스트에 Multiple IP 주소를 지원하지 않기 때문에 무선에서 사용이 불가능했다. 이를 극복하기 위해 개발된 것이 IKEv2 프로토콜로써 기존의 IKE의 페이스 개념을 계승하고 있고 동일한 ISAKMP(Internet Security Association and Key Management Protocol) 메시지 포맷을 사용하고 있지만, 기본적으로 Phase 1에서 교환되어야 하는 기본 메시지 개수가 6개에서 4개로 줄어들었고 인증방식도 기본의 4가지 방식에서 2가지 방식으로 줄었다. 또한 Dos(Daniel of Service) 공격에 잘 견디도록 설계되었다. 본 논문에서는 SSFnet(Scalable Simulation Framework Network Models)이라는 네트워크 보안 시뮬레이터를 이용하여 IKEv1과 IKEv2의 보안전송의 키 교환 지연값을 비교 분석하여 성능을 측정하고 그에 따른 문제점과 개선 방안에 대해 연구하였다.

The article identifies and theoretically substantiates the trends of national resilience in the context of establishing the security of the country and its civilizational subjectivity. The strategy of development of the pedagogical university in the conditions of European integration into the European educational and scientific space based on certain characterological features of the personality of the volunteer in the context of allocation of personal resilience is developed. The analysis of both external and internal challenges and threats to the civilization of the country needs to be understood in the context of economic, socio-political, legal, military-political, spiritual-cultural, educational-scientific and network-information resilience. The concepts of "national resilience" and "national security" are quite close - at first glance, even identical. However, a deeper understanding clarifies the differences: national security is a state of protection of the country identity and its very existence, the realization of its national interests. In turn, resilience is a fairly effective strategy and a fundamental guarantee of national security. At the same time, it is extremely important to understand that both national security as a state and national resilience as a strategy are only means of achieving and developing a strong and humanistic civilizational subjectivity of the country. After all, such subjectivity opens for citizens the opportunity for development, dignified self-realization and a proper life. The restructuring of the volunteer's motivational sphere is due to the dominance of such leading motives, which are focused mainly on maintaining and restoring health, which leads to distorted meaningful life goals: isolation, alienation, passivity, inertia, reduced activity, limited communication, etc. The characteristics of relatively stable human behavior include several primary and secondary properties. The primary (relevant) properties include patience, trust, hope, faith, confidence, determination, perseverance, and love; the secondary - punctuality, neatness, obedience, honesty, loyalty, justice, diligence, thrift, accuracy, conscientiousness, obligation, etc. The restructuring of the volunteer's motivational sphere is due to the dominance of such leading motives, which are focused mainly on maintaining and restoring health, which leads to distorted meaningful life goals: isolation, alienation, passivity, inertia, reduced activity, limited communication, etc. The characteristics of relatively stable human behavior include several primary and secondary properties. The primary (relevant) properties include patience, trust, hope, faith, confidence, determination, perseverance, and love; the secondary - punctuality, neatness, obedience, honesty, loyalty, justice, diligence, thrift, accuracy, conscientiousness, obligation, etc. The use of information and communication technologies in volunteering will contribute to the formation of resilience traits in the structure of personality formation. Directly to the personal traits of resilience should be included methodological competencies, which include methodological knowledge, skills and abilities (ability to define ultimate and intermediate goals, plan, conduct and analyze knowledge, establish and implement interdisciplinary links with disciplines of medical-psychological-pedagogical cycles, etc.). All these competencies form the professional resilience of the volunteer.

인간 활동의 대부분이 플랫폼 안으로 빠르게 좁혀지는 비대면 사회를 지난 몇년간을 지나오면서 외부 활동에 대한 제약이 결국은 디지털 기술의 내부 확장성을 가져왔다. 그 중 메타버스는 사실상 현실을 대체하며 다양한 분야에서 활용 가능성을 높이고 있다. 그러나 메타버스, 특히 장애학생의 교육적 효과와 관련된 연구는 여전히 부족한 미지의 영역이다. 본 논문은 메타버스 교육이 사회선과 포용적 교육을 실현하기 위해 장애학생들의 다양한 요구에 부응하는 교육분야를 확대하고 있으며, 상호작용의 장벽 해소 등 소통효과가 두드러진다는 점에 주목한다. 연구방법으로는 의사소통적 기능에 중점을 준 장애학생 교육방법과 AR/VR, 메타버스를 연계한 논문에 대한 문헌연구와 전문가 인터뷰, 기사, 칼럼 등을 살펴보고, 특수장애교육에 대한 정책 제언과 시사점을 살펴본다. 연구의 한계가 확인되고 있지만, 원추이론을 통한 직접적인 몰입형 경험이 교육적 효과의 극대화를 제공하고, 사회적 선의 실천 차원에서 학습의 동기부여, 흥미, 접근성, 학습권확보 등 장애학생들의 인권을 실현하는 포용적 교육에 유의미한 결과가 있음을 발견한다. 향후 장애학생을 위한 메타버스 교육의 발전적 활용에 대한 후속 연구가 진행되길 바라며, ICT 사회에서 사회적 취약계층이 기술에서 소외되지 않도록 포용적 정책과 혜택을 꼼꼼히 관찰하기 위한 다양한 학제간 논의가 이루어지길 바란다.

The dairy industry, as part of the broader agricultural sector, is classified as a basic industry to the Korea economy. Basic industries provide income to a region by producing an output, purchasing production inputs, services and labor. An integrated, multidisciplinary approach for the next generation of dairy products with added health benefits represent the direct economic contribution. The commercialization of "nutritional" functional foods can only be successful if the consumer is confident in the scientific validity of the claims. Modern biotechnologies such as genomics, genetic expression and biomarkers of health performance suggested to whole dairy products, such as fluid milk, butter, cheese, ice cream and frozen dessert products (German, 1999). The following definition makes the point that dairy products can provide a nutritional value beyond the basic nutritional requirements: 1) The dairy industry has the opportunity to improve the health and well-being of its customers and/or to reduce their risk of disease through dairy products with added activities. 2) Functional dairy products are those that can be demonstrated to benefit target functions in the body in a way that improves the state of health and /or reduces the risk of disease. They are food products that are consumed as part of a normal diet rather than pills or supplements. 3) Dairy products based on functionality will need to link the scientific basis of such functionality to the communication of its benefit to the general public. 4) Both the efficacy and the safety of the food components with health benefits will require evidence based on the measurement of scientific biomarkers relevant to their biological responses and health end points. 5) Sound evidence from human studies based on intermediate health end points using accepted biomarkers will provide the basis for promotional messages divided into two categories-enhanced function and reduced risk of disease. 6) Success in solving key scientific and technological challenges will only be achieved by interdisciplinary research programs to exploit the scientific concepts in functional dairy science.

Background and Objectives : The current study aimed to 1) compare of Lingual function and alveolar sounds between 4-year-old Korean children with and without ankyloglossia, 2) investigate the correlation between ① maximum lingual length-protrusion(MLL-P) and percentage of consonants corrects(PCC) focused on alveolar sounds, ② lingual movement and PCC focused on alveolar sounds, ③ MLL-P and lingual movement. Materials and Method : Twenty-two 4-year-old children participated as subjects in the study: a control group of 11 normal children and an experimental group of 11 children who were previously diagnosed as having ankyloglossia. They were measured for lingual function (lingual length, lingual movement) and the performances of speech articulation. Results : Children with ankyloglossia displayed significantly shorter MLL-P than 4 year normal children. Experimental group displayed significantly worse lingual movement, lower PCC in Picture consonants test, and lower PCC of alveolar sounds than control group. Ther was significantly high correlation between MLL-P and lingual movement of experimental group. Conclusion : This paper describes clinical measure and functional aspects of the tongue. Such baseline analysis provides a more definitive appraisal of lingual function as well as a more objective basis for diagnosis and treatment of ankyloglossia.
