Fatigue is one of the most common complaints of cancer patients. In this study, we analyzed the change of fatigue level and general symptoms as time go by, so that, we could explain more on the mechanism and chance of fatigue in relation with treatment, and explore the influencing factors. Method: The subjects of this study were 50 GI cancer patients who have visited the cancer center of A hospital in Suwon. We measured fatigue by using the Revised Piper Fatigue Scale(RPFS) at the time of starting and finishing induction chemotherapy, and starting the 2nd cycle of chemotherapy. Results: 1) The fatigue score was 2.81, 3.73, and 3.82 in a 10 point scale at the time of starting and finishing induction chemotherapy, and starting the 2nd chemotherapy, respectively. This means fatigue persisted until after the treatment. 2) Fifty two percent of participants complained of some kinds of symptoms when starting the treatment, and the proportion increased up to 92% when finishing the treatment. 3) Fatigue scores were significantly high in patients with fatigue-related symptoms than for patients without those symptoms. 4) Fatigue scores showed significant differences according to patients' general characteristics such as age, educational level, economic status, occupation, diagnosis, hematocrit, weight, and amount of sleepy. Conclusion: We have to develop intervention strategies to reduce fatigue in cancer patients in the consideration of influencing factors.

A RESEARCH ON EFFECTIVE FIRE/DISASTER PROTECTION OF UTILITY TUNNEL IN KOREA

Park,Hung-joo,Son,Bong-sei,Jee,Nam-yong 한국화재소방학회 1997 한국화재소방학회 학술대회 논문집 Vol.1997 No.-

The pipes and cables buried below ground, which may have helped to improve city landscape, is becoming direct and indirect causes for various kinds of disaster in Korea. Every advantage from the use of utility tunnel can not be converted in a dollar since there is associated huge contribution to safe urban environment. The Korean government has a certain role to play in helping promote utility tunnels for the past years. Most recently, many utility tunnels have been being checked to find out safety level, especially fire safety level, and main problems and shortcomings are checked out as a result of this survey. Because the fire safety level of existing tunnel is low, possible approaches and solutions are presented according to the analysis of fire safety level. In order for these approaches to be effective, existing tunnel should be supplemented appropriately and extra equipment must be installed according to the solutions. Hopefully, by performing both improvement of existing utility tunnel that provide a fire/disaster proof and introducing new types of tunnel which influence utility management and maintenance, the recent disaster rate in Korea can be diminished up to a desirable rate in a near future.

박병희,장경준,신지용 大韓神經精神醫學會 1996 신경정신의학 Vol.35 No.3

본 연구는 Rest가 고안하고 문용린이 번안한 주제정의검사(DIT)를 사용하여 청소년기의 도덕발달수준을 알아보고 비행청소년의 도덕발달수준과 비교하여 그 차이점에 대해 알아보고자 하였다. 먼저 신지용 등(1995)이 정상 고교생군에 대해 조사하였고 본 논문에서는 비행청소년군의 조사와 두 군의 비교 분석을 통해 청소년기의 도덕발달수준과 관련된 변인의 유의성을 검증하였다. 연구대상은 정상 고교생군 254명과 비행청소년군 285명이었다. 설문지 작성시 문항에 대한 이해 부족으로 생기는 오차를 줄이기 위하여 자세한 설명과 연습을 실시하였고 충분한 시간이 주어지도록 하였다. 수집된 자료는 컴퓨터로 채점되었으며 정상군의 자료와 함께 분석되었다. 연구의 결과는 다음과 같이 요약할 수 있다. 1) 정상 고교생군에 비해 비행청소년군은 도덕발달수준이 유의하게 낮게 나타났다(p<0.05). 2) 비행청소년군의 경우 종교에 따라 도덕발달수준의 유의한 차이를 보였으며 이는 천주교와 불교간의 수준차이로 검증되었다. 3) 정상고교생군과 비행청소년군의 PM점수 차이의 상관관계 분석 결과 아버지, 어머니의 교육수준 요인에서 주효과가 유의하게 나타났으며 주성장지는 상호작용 효과에 유의한 것으로 나타났다. Objectives : This study was directed to compare the moral developmental levels between normal and delinquent adolescent groups. And the authors also intended to find the demographic variables that influence the differences of moral levels between two groups. Methods : Defining Issue Test questionnaires were applied to 285 delinquent adolescents and the data were compared and analyzed with the normal control data of previous Shin's study(1995). Results : 1) The PM scores(scores of principled morality) of delinquent group(28.6±15.01) was significantly lower than that of normal control group, 41.8±15.10(p<0.05). 2) The PM scores were not significantly different according to the age in delinquent adolescents. 3) The PM scores were significantly different according to the religious varible, especially between Catholic and Buddhism in the delinquent adolescents. The Catholic group recorded the highest and Buddhism, the lowest. 4) Comparing the scores between normal and delinquent adolescents, there were significant differences according to the educational of mother and father, and the birth places. Conclusion : The moral developmental process of adolescents requires the proper education from parents, school, religion or other social environment. The corrective reexperience of normal developmental steps are needed especially to the delinquent adolescents.

Background : The goal of this study was to establish the QA items and guidelines for preventing and improving of safety management. Therefore we investigated the nurses' recognition and knowledge of the safety and risk procedures and policies, and the agreement between the nurses beliefs on the degree of miportance of those procedures and policies, with actual implementation in hospitals. Method : The subjects of this study were 201 nurses who participated in a program called continuing education for nurses, which held in December, 1993. Result : The results of this study were as follows: 1. Among 18 types of hospital risks, the items that scored highest or the need of closer attention in safety management was the needle stick, medication errors, falling, and bed sores. 2. In most questions of the 18 incidences, the nurses showed that the estimated result would have positive signs except for hospital infections, burns, and bed sores. 3. Even though the survey shows that incidences and types of occurences varies according to the person's age and the time of incident, they mostly occur between midnight to 6AM. Falls and bed sores can be seen more in the elderly. Medication errors, hospital infections and bums are frequently found between the ages of one through twenty. 4. There was a higher mean score for recognizing the importance of those items than the importance of implementing them. Conclusion : In summary, nurses did perceive the need of safety management but the hospital policy for proper safety management was not established. So we recommended that the hospital administration would undertake an early detection and proper management system for hospital precautions, based on QA items & guidelines presented in this study.

Voltatile flavor components in salt-fermented Gizzard shad were analyzed by simultaneous steam distillation-solvent extraction gas chromatography/mass spectrometry. One hundred compounds were detected in sample. These compounds were composed mainly of aldehydes(15), ketones(14), alcohols(18), aromatic compounds(7), N-containing compounds(9), esters(15),S-containing compounds(8) and miscellaneous compounds(14). The alcohols were the large amounts in the number of flavor compounds detected in sample. But these compounds may not have an impact on sample flavor because of their high flavor thresholds. The flavor compounds such as aldehydes, ketones, N-containing compounds, esters and S-containing compounds were supposed to be playing a major role in salt-fermented Gizzard shad.

김용순,박지원,박연옥 한국의료QA학회 1997 한국의료질향상학회지 Vol.4 No.1

Background : An important issue in health care today is in trying to center service around the hospitalized patient. There is a "kindness Movement" developing now. Where in the focus of Health Care is being changed from simply treating the basic physical needs of the patient with sophisticated technology. to keeping emotional well being healthy with more humane and attentive treatment. In our attempt to reach the goal of a completely satisfied patient, we undertook a study of the common complaints of patients, and the subsequent nature of the interventions. Method : The study was carried out in two stages, first the patients made known their complaints by filling out questionnaires, then we collected data on the attempts to alleviate the complaints. The questionnaire provided 19 different complaints, which were then analysed for such variables as content, source of complaint, persons treating the complaint, and length of time and method used to solve the complaint. Result : 1. The Chief complaints made by patients(99.1%) were of physical discomfort, such as pain, nausea, vomiting, indigestion, diarrhea and constipation. 2. The complaints were vioced primarily by either a member of the patient's family, or by the patients themselves(78.4%). 3. The complaints were intervened by nurses alone(53.5%), physicians alone(25.5%), or by nurses and physicians together(19.25%). 4. The method by which the complaints were resolved included the utilization of prescriptions(55.7%), turther explanation and education (25.5%) and notification after treatment(13.2%). 5. Most complaints were voiced during the dayshift (42.6%, 7:00~15:00), followed by the evening shift(36.0%, 15:00~22:00) ;and then the nightshift(21.3%, 22:00~07:00). 6. The time required for successful resolution of the patient's problems varied from 10~88.9mi, according to the nature of the complaint. Conclusion : Hopefully by knowing beforehand the nature of both complaint and intervention, we can anticiapte problems and shorten reaction time, in order to provide for a more satisfied patient.

Background: One of the major side effects of cancer chemotherapy is myelosuppression. Neutropenia and/or thrombocytopenia are dose-limiting factors in chemotherapy. Colony-stimulating factor induces proliferation and functional maturation of hematopoietic progenitor cells. GM-CSF is primarily active on progenitor cells of granulocytic and monocytic lineage. Methods: Fifteen patients with histologically proven malignancy diagnosed at Chungnam National University Hospital from January 1993 to August 1995 were included in this study. We could evaluate the clinical efficacy of GM-CSF in 13 patients undergoing FCL(5-FU, Carboplatin and Leucovorin) chemotherapy; the first cycles involved no GM-CSF while the second cycles involved GM-CSF on day 6 through 15 of chemotherapy. Results: 1) The subjects were fifteen patients in all, there were five patients with head and neck cancer, which was the most common types of maligancy. There were four patients with colon cancer, two patients with stomach cancer, and one patient with breast cancer, gallbladder cancer, cervix cancer and cholangiocarcinoma respectively, two patients, who did not complete two cycles of chemotherapy were excluded. 2) Age distribution was from 38 years to 78 years with a median age of 57. 3) In FCL chemotherapy cycles with GM-CSF, the duration of neutropenia(<500/μL) was 0.5±0.3 day, while FCL chemotherapy cycles without GM-CSF, it was 2.9±0.7 day(P=0.008). 3) There was no significant difference in platelet count between the two chemotherapy cycles(P=0.133). 4) Febrile duration without GM-CSF was 4.9±2.1 day, but with GM-CSF the duration was 1.3±0.7 day, which was significantly different(P=0.003). The duration of antibiotics use with GM-CSF was 1.7±1.2 day and without GM-CSF was 6.8±3.2 day, also significantly different(P=0.002). But hospital stay between the two cycles were not significantly different(P=0.064). Conclusion: GM-CSF was effective in preventing or restoring bone marrow depression after FCL chemotherapy.
