This study was carried out to evaluate the adequacy of serving sizes of those packaged processed foods in Korea which are designed to provids one meal or snack for one person. There is a lack of data on reference serving sizes which are essential components in the nutrition information provided on food labels. After compiling the average weight of packaged processed foods available in the market in Korea, a questionnaire was formulated to evaluate the adequacy of the serving sizes on 56 packaged processed food items of 188products using 25 female university students as a consumer group. The results showed that 65.5% of the packaged processed foods had adequate serving sizes. In general, current packaged sizes for bread and carbonated drinks were found to be too large. The proposed reference serving sizes in this research appear to be somewhat different from the ones suggested by the Korean Nutrition Society s $7^{th}$ Recommended Dietary Allowances for Koreans and by the Food and Drug Administration (USFDA) in the U.S. The serving sizes suggested by the USFDA appear to be too large for beverages and too small for snack foods when these are applied to the Korean population. It is suggested that the size of beverages in the Korean market should be reduced, and smaller sub-packets of snacks (each for one serving) should be packaged in a larger pack, for ease of use of nutrition information by consumers as well as for the reduction of food waste. In the future, other representative population groups should be included in the determination of reference serving sizes.

Purpose : this study purposed to investigate school nursing phenomena in Korea by applying ICNP, the international standard nursing classification system developed by ICN, and to compare school nursing phenomena at elementary, middle and high schools. Method : The subjects of this study are 110 nursing teachers from 82 elementary schools, 16 middle schools, and 12 high schools. In the survey, subjects were asked to score the degree to which phenomena and characteristics of Korean school nursing, identified in previous research, on a 5 point scale. Questionnaires were distributed and recovered by mail and email. The period of data collection was 6 months from July to December 2003. The general characteristics of schools and nursing teachers were represented with frequencies and percentages, the phenomena and characteristics of school nursing with the mean score of the questions, and the phenomena school nursing by school grade with ANOVA and Duncan's posterior analysis. Results : 1) As for the characteristics of schools according to school nursing phenomena related to human behavior, the mean score of questions on inadequate stress management was highest at 3.24 points followed by the score on inadequate weight control (3.23), inadequate eating habits (3.22), the risk of spine disorders (2.68), inadequate emergency management (2.62), inadequate response to sex -related problems (2.19), and smoking and drug use (1.85). 2) As for the characteristics of schools according to school nursing phenomena related to human function, the mean score of questions on oral health management was highest at 3.11 points followed by the score on the risk of digestive system disorder (2.87), improper eyesight management (2.81), the risk of respiratory system disorders (2.75), lack of sexual identity (2.52), and inadequate contagious disease control (2.12). 3) As for the mean score according to school nursing phenomena related to environment, the score of the risk of accidents in classroom was highest as 2.68 points followed by the score of the risk of accidents around the school (2.65), maladjustment to school (2.62), the risk of accidents outside the classroom (2.43), inadequate learning environment (1.83), the risk of exposure to socially and physically harmful environment factors (1.82), and inadequate waste disposal (1.77). 4) This study tested the mean scores of questions corresponding to each school nursing phenomenon in order to see if there is a difference in the school nursing phenomenon among elementary, middle and high schools, and performed Duncan's posterior comparison for school nursing phenomena. A significant difference was found at p<.1. According to the results, school nursing phenomena found to be significantly different among elementary, middle and high schools was smoking and drug use (p<.05), which appeared more problematic in high school than in elementary school. phenomena such as inadequate eating habits, inadequate weight control, inadequate response to sex-related problems and inadequate waste disposal were also found to be statistically different at p<.1; however, according to the result of Duncan's posterior comparison, no difference was found among groups in improper eating habits and improper response to sex-related problems, and a significant difference was found between middle and high schools in inadequate weight control and inadequate waste disposal. Conclusion: Based on the results of this study, it is necessary to plan school health projects focused on the characteristic school nursing phenomena that had high scores and to develop and execute school healthe projects in accordance with the characteristics of elementary, middle and high schools. Considering that the scores of school nursing phenomena related to human behavior are high, it is necessary to introduce school health promotion projects in a systematic way.

Medication is a kind of medical service and a therapeutic nursing function which takes large portion of nursing service and requires complicated procedures. So many different medical personnel should be involved and cooporate each other in order to accomplish medication. Medication is also a vital nursing service, So nurse feels heavy responsibi lity in that she gives medication to the patient finally, so she has much responsibility if medication error is happened. Therefore it seems very important to clarify the problem of medication system and method, and find the subculture of medication situation because it may promote nursing productivity. The study was conducted to 1. Describe and interpret medication situation. 2. Find out the problem of medication system and method and on alternatives. 3. Compare the medication system and method of hospitals which are located in Seoul with object hospital Ethnographic methodology was used to study medication situation by doing participant observation and interview of health care personnel. Ten nurses and three nurse aids were interviewed. Two residents and internists, two phamacists and two accountants were also interviewed. Data was obtained and analized according to Developmental Research Sequence introduced by Spradly. On the basis of this data the results were as follows. 1. The overall flow of medication system was devided into six stage : first, checking doctor's order : second writing doctor's order, : third, transfering slip into the related departments such as account department, pharmacy : fourth, distribution of medication from pharmacy to unit : fifth, identifing medication by nurses : and finally, medicating to the patient. Behaviorors have been under a lot of stress in that they have to do much works, especially paperworks, So too much time were needed. They also have been suffered interpersonal conflicts among health care personnel and role conflicts in the process of doing medication service. 2. In the process of checking order, the problem was that too much time was required for checking order and paperwork. The more the order changes the more the paperwork is. Nurses have been suffering difficulties in calling internist in order to get bill. Even if writing down slip for medication order is doctor's job, Sometimes nurse has been expected to write slip by doctors or nurse would write slip beacuse of two much complexities and efforts for calling doctors. If the slip were incorrect, much time complicated procedures were more required for correcting it. So delay of administering drug would be resulted consequently. Drugs were delivered from pharmacy to units by delivery agent and phamacist. But because drugs were delivered without arranging room number of patient. Nurse should rearrange drugs in order of the room number So it had made waste time and effort, and Even when emergency drugs were needed, Prompt delivery of drug was not easy because of many reasons. For nurses, it took too long in the identification of the right drug. Actually nurses have heavy burden when medication error happens because nurse is the final actor who gives medication to the patient, So every three shift nurse ought to check drugs as soon as every shift begins. That's why it took too much time due to repeated confirming procedure. When nurses had to go patient room in order to give medications, there were difficulties in watching patient until the patient take medicine correctly. So it was impossible to check every patient wheather he took medicine or not especially in hectic situation. 3. There were many hospitals in Seoul which have similar medication system and method as object hospital according to the results of questionaire. This means that many hospitals have been suffering srimilar problems which were identified in object hospital. 4. Recommendations for promoting simplification of medication system and method were the following : Redesigning of slip from two pieces of paper into one : early discharge announcement system, and slip confirming through computer and controlling of period of prescreption from one day to two or three days : designing personal drug storage box for each patient and using it. If nurses follow the recommendations, they will make medication short & simple, and also have enough time of direct nursing care 5. Even though there were many difficulties in medicating patients. Medication itself has been considered as a caring among nurses because it makes rapport between nurse and patient. So nurses had better accept medication as a portion of nusing service not a original portion of phamacist. There are some limits in this research in terms of confining to only one unit of one hospital, and treating it especially in view of nurses' aspects, So further researchs should be continnued from various kmds of viewpoints of doctors, phamacists and so on. ${\cdot\cdot\cdot}$. Especially esthnographic study of computerized medication system and method seems to be followed.

축산 폐기물에서 항생제에 대해 내성을 가지는 균주를 분리하여, 다양한 항생제에 대한 내성특성을 확인하고, 감마선의 조사에 따른 내성균의 항생제 내성 특성변화와 살균효능에 관한 연구를 수행하였다. 그 결과, 돈분과 돈분퇴비에서 분리된 균주 중 Esherichia coli와 Brevibacterium sp.이 다제내성균으로 확인되었다. E. coli는 13종의 항생제 중 9종의 항생제에 대해 내성을 나타내었으며, Brevibacterium sp.는 7종의 항생제에 대한 내성을 나타내었다. 이 두 가지 대표 다제내성균에 대해 감마선을 이용한 살균실험을 시행한 결과, Esherichia coli는 항생제에 대한 내성이 돌연변이적으로 발생하기 쉬운 균주이나 감마선을 이용해 효율적으로 제어할 수 있는 것으로 나타났고, 그에 반해 Brevibacterium sp.는 저선량에서 감마선에 대한 내성을 나타내어 상대적으로 감마선을 이용한 제어가 용이하지 않았다. Brevibacterium sp.는 2.0 kGy의 조사량에 대해 Esherichia coli에 비해 약 100배 정도 낮은 살균 효율을 보임으로써, 감마선에 대한 내성이 강한 것으로 나타났다.

Consumers empty perfectly safe to intake perishable foods everyday if they are older than what prints on expiration date. The variation in expiration dating is freshness labeling represented in various terms such as sell by, package, best before, and so on. Regardless of the terms used and meanings are attached, consumers tend to conceive of freshness labeling on food as end of its shelf-life. Consequently, the food waste becomes a big issue for businesses in food sector. In an effort to demonstrate flexibility on this, KFDA(Korea Food & Drug Administration) introduced "best before" date in domestic market place to reduce food waste, based on the food safety test conducted by KCA(Korea Consumer Agency 2009). The results indicated freshness labeling on food should not be considered as the end of its life. Current study examined the underlying mechanisms(i.e. risk perception, self-construals, and indecisiveness) that influence consumers' intention on prolonged consumption of food beyond its stamped date when the KCA test results are shown to them. In addition, the moderating effect of regulatory focus is tested in the causal relationships between underlying mechanisms and different groups of prolonged consumption intention. Study participants are divided into three groups of prolonged consumption intention: no-change, moderate-change, and wide-change. The group with moderate-change in intention being as our point of reference, logistic regression analyses are conducted on 276 sample population. The results indicated that consumers with high source credibility risk are likely to show wide-change in intention on prolonged consumption while physical risk did not show significance. The consumers with independent self-construal are likely to show no-change in intention on prolonged consumption while interdependent self-construal did not show significance. Indecisiveness showed association a group with wide-change in intention on prolonged consumption. The moderating effect of regulatory focus showed valid results in most situations; the promotion-focused consumers showed wide-change in intention, while prevention-focused consumers showed no-change in intention. Furthermore, the moderating effect of promotion-focus showed a dominant position over the causal effect of indecisiveness in which decisive consumers(i.e. no-change in intention); if they are promotion-focused they tend show for the wide-change in intention instead. It is important to note that for those promotion-focused consumers(or situations), promotion-related arguments are more effective, while for those prevention-focused consumers(or situations) prevention- related arguments are more effective means of persuasion.

Recently, there have been many research on fever management using u-healthcare technology. Especially, fever of infants requires continuous monitoring of body temperature by parents. For infants between 4 weeks and under 5 years old, it is recommended to use an electronic thermometer or chemical thermometer in the axilla, or to use an infrared thermometer. However, in order to overcome the reality of not being able to waste significant time on continuous monitoring, there have been demands of patch type thermometers with the internet of things (IoT) and wireless communication technologies. Existing IoT thermometers are difficult to attach to infants' body because they do not take into account its size, and their interoperability is not guaranteed because they do not comply with standards in communication. Therefore, in this study, a patch-type thermometer with a diameter of 20 mm and a weight of 2.9 g was developed to manage the fever of infants, while it communicates wirelessly with Bluetooth Low Energy (BLE) communication protocol and complies with IEEE 11073 PHD(Personal Health Device) at the same time. We verified its performance under the requirements of thermometers regulated by the Korean Ministry of Food and Drug Safety.

심장수술시 중심 정맥 상관은 필수적으로 시행해야 하는 수기 중 하나이다. 보통은 내경 정 맥이나 쇄골 하정맥에 경피적 상관을 하는데 기흉이나 혈흉 등의 합병증을 유발할 수 있고,영유아의 경우는 반복된 상관실패로 많은 시간을 허비할 수 있다. 그래서 저자들은 몸무게 10kg이하의 영유아 개심술시 홍골절개가 완료된 상태에서 무명정맥을 노출하여 여기에 삽관을 한다. 술후 중환자실에서 이 무명정맥관은 주로 좌심방이나 폐동맥의 압력을 측정하는데 이용하고 관자가 혈역학적으로 안정되면 우심방이나 상대정맥으로 후퇴시켜 수액보급이나 약물투척 경로로 이용한다. 본원에서는 1989년 이후로 96예에서 시행하여 왔으며 이 삽관술로 인한 기흉이라 혈흉은 없었고 정맥관제거시 출혈에 의한 합병증도 경험하지 않았다.
