This study was performed to investigate dietary behaviors and consumption of health food in cancer patients. The subjects were 163 cancer patients recruited from the general hospital in Seoul, Korea. The data were obtained by the structured self administered questionnaire. The mean age of subjects was 51 years. Most of subjects didn't eat the visual fat of meat and chicken skin. The mealtime of the subjects was generally regular and most of subjects had breakfast. The subjects of this survey liked to eat foods with sweet taste but disliked to eat hot, salty and sour taste ones. The preference for fish, marine products and vegetables was high but that for instant foods and frying foods was very low. Most of subjects consumed the foods that is generally known as anticancer foods such as vegetables and fruits. On the other hand, most of subjects didn't intake butter, margarine, and frying foods that is known as risk factors of cancer. The majority of subjects$(84.7\%)$ consumed the health food The main reasons for taking health foods by subjects were to cure disease$(58.0\%)$, to prevent disease$(45.3\%)$, to supply nutrients$(39.3\%)$, to maintain the mental state$(12.7\%)$ and to recover fatigue$(10.7\%)$. Majority of subjects$(66.0\%)$ spent money more than 200,000 won/month to buy health foods. The purchasing channels of health foods by subjects were recommendation by family or friend$(64.0\%)$, by physician/pharmacist$(18.0\%)$ and by nutritionist or dietician(6.0), and advertisement through TV or radio$(12.0\%)$. The types of taking health foods of the subjects were vegetable extracted food$(60.0\%)$, mushrooms$(51.3\%)$, Lactobacillus food$(25.3\%)$, enzyme food$(22.6\%)$ calcium containing food$(20.0\%)$ and so on. The results of the current study show that although many cancer patients already practice healthy dietary behaviors, there is a substantial proportion who do not and most of cancer patients consume health foods.' Further intervention is needed to explore the effect of health foods in cancer patients

Informatizing of society is a important factor which has been changing the method of forming human relationship and a structure of society and politics from industrial society. In information society, a person can gain useful informations in behalf of him(her)and do maximization of his(her)interests by using new-media. Individuals can extend more creativeness, capacity, and power than before without limitation. Information society which is composed of vary individuals has not massification, centralization, standardization, synchronization but demassification, decentralization, pluralization, synchronization as key concepts. As to political phenomena a socio-political group that can control other groups or individuals exists no more. In other words a hegemonic group or person isn't any more. The plural political institutions and new procedural methods of liberal democracy appear and is used in political process. Therefore the coming of information society means a change in political phenomenon as a social studies education's object. In this respects it is needed thinking about the relevancy of democratic citizenship education in social studies education. The goal, contents, and methods of political education is reviewed in view of information society.

Ethanol sorption experiments were performed for 9 kinds of particulate minerals to find novel sorbent material with a higher sorption capacity than dried soil or sand used in the spill accident of liquid hazard chemicals. Since there was no standard method for the sorption evaluation, an experimental protocol was proposed to determine sorption capacity and rate for spilled hazard chemicals over nonpermeable floor. The sorption capacity exhibited higher values for the porous minerals of expanded vermiculite (1.64 g/g), perlite (0.57 g/g), orchid stone (0.48 g/g) and diatomite (0.34 g/g) than 0.02 g/g of masato. Macropores larger than 1 μm were found more responsible for the sorption than nm-sized micropores by N2 adsorption measurements. Furthermore, the sorption was found to reach to a steady state within 10 minutes from the dependence of an immersing time on the capacity. 액상 유해 화합물 누출 사고시 사용하는 건토/모래에 비하여 큰 수착용량을 가지는 새로운 소재를 발굴하기 위하여 9종의 과립형 광물 시료들에 대한 에탄올 수착 실험을 수행하였다. 수착 성능을 평가하는 표준화된 방법이 부재하여, 비침투성 바닥에 고인 액상 화합물에 적용 가능한 수착용량 및 수착속도를 결정하는 시험법을 제안하였다. 수착용량은 마사토(0.02 g/g)에 비하여 다양한 기공 구조들이 발달한 팽창질석(1.64 g/g), 진주암(0.57 g/g), 난석(0.48 g/g), 규조토(0.34 g/g)에서 큰 값을 가졌다. 질소 흡착 실험을 통하여 nm 크기의 미세기공에 비해서 μm 이상의 큰 기공에서 효율적인 수착이 발생함을 확인하였다. 또한 침수 시간에 따른 수착용량 변화를 측정하여 수착이 10 분 이내에 대부분 이루어짐을 확인하였다.

A defect of decrease in TCP throughput can be investigated in asymmetric environment of different uplink and downlink bandwidths. Under two-way TCP traffic, the total link utilization is decreased by the successive injection of data packets in buffer. To solve these problems, terminal ACK filtering and packet scheduling mechanisms are introduced in this paper. ACK filtering eliminates the buffered ACK packets and transmits recent ACK packets in the uplink with limited bandwidth. Packet scheduling is the method of preventing 'clustering' and 'ack compression' states which are generated in the two-way TCP traffic. The guarantee of the data traffic in reverse TCP connection and the high throughput in forward TCP connection are investigated by simulation.

Hemodialysis that to maintain life quality and may be preliminary stage of kidney transplantation is essential in end-stage renal disease(Esrd) patients. Since 1996, Brescia-cimino are used to internal radio- cephalic fistula and this fistula method was the most popular in world-wide. And then variable methods (e.g, Autogenous, PTFE, Dacron etc.) were usually tried instead of above standard fistula. We experienced 75 fistulas in 62 cases from Jan. 1993 to Dec. 1996 and among 75 fistula operations standard radio-cephalic fistula was 56, brachio-cephalic fistula 10, graft fistula 9. Early patency failure rate of A-V fistula was 9 cases, 14.5%. Significant factors to effect in patency of A-V fistula were propably diabetic mellitus, venous diameter, graft material and were not related to age/sex, blood pressure, BUN/creatinine etc. In conclusion the reduction of early patency failure rate in A-V fistula is to maintain long patency rate of A-V fistula.

The structure of peace in Korean peninsular has multi-levels and dimensions. The unification for peace system building is connected with division structure of Korean peninsular. It was done by logic of powers’ strength and stuck through Korean War. Therefore, the basic nature of unification has international problems and nation interior tasks. This could be adapted logic of peace building. The peace of Korean peninsular can be possible throughout the settlement of super powers’ interests in northeast Asia and realized by exchange and cooperation between south and north Korea. Peace and unification of Korean peninsular is potential and intrinsic essentially. An individual can not control this situation. In perspective of a person’s peace keeping, it could be expressed form of a structural violence because circumstances of conflicts are ordinary and its possibility is authentic. Meaning of peace in Korean peninsular is linked with a negative that stands for absence of personal violence and positive peace that means elimination of structural violence concept. This will be also concerned with unstable and stable peace. The former means absence of war or conflict with openness for struggle. The latter pays no attention to use military power among nations. Of course, negative-unstable and positive-stable peace frames can be used real world mixed. These levels of peace are represented an integrative peace governance that is actualized by a sustainable peace. Unification education pursues a positive-stable and sustainable peace more. Peace centered unification education will be improved via sequential transformations of levels of peace gradually higher.

Purpose: The natural history of deep vein thrombosis (DVT) has been of increasing interest since the mid-1960s. Prevention, diagnosis & management of DVT has been continously development. Howerver, Early diagnosis for prevention & effectivly choice of management method of DVT has been difficult problem. Methods: We reviewed retrospectively 42 patients who were admitted and out patients department follow up to Department of Surgery, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, for treatment of DVT from November, 1990 to August, 1998. Results: There was a wide age distribution from teenage to 9th decade, and peak age distribution was 7th decade (23.8%). It occured mote old age than younger age. Sex distribution, male to female, was about 1.2 : 1 and occured more male than female. Main chief complaint in pateints with DVT at initial our hospital visit was painful swelling (57.1%), and followed by swelling (33.3%) of lower extremity. Duration of sign and symptom in pateints with DVT at initial our hospital visit was more than I month (38.1%), and followed by Iess than 1 weeks (31.0%). The left side of lower extermities was more frequently involved than that of right side, left to right ratio was 2.1: 1. Most location of involved vein of lower extremity was Popliteal vein (71.4%), and followed by Superficial femoral vein (55.4%), Calf vein (44.6%), and Common femoral vein (39.4%) in ration of 56 limbs. More frequent risk factor of DVT was major surgery (28.6%), and followed by immobility (16.7%). but most frequent risk factor was idiopatbic (31.0%). Diagnosis of DVT was made with color doppler (90.5%) and venogram (57.1%). Treatment was done with intravenous or oral anticoagulants in most pateints (90.5%), Forgarty thrombectomy (7.1%), and Bypass and A.-V. fistula (2.4%) and followed by only or combined oral anticoagulants theraphy. Treatment of DVT was wide duration from less than 3 month to more than 1 years. It was done for less than 3 month (52.4%), and followed by 6 to 12 month (19.0%), 3 to 6 month (14.3%) and 14.3% were continued more than I years. During oral anticoagulant theraphy, GOT/GPT elevation was observed in 26.2%, and 23.8% was detected bleeding tendency (hematuria). Post-treatment response of DVT was divided three group, good (31.0%), moderated (42.9%),'no response group (26.3%) in pateint complaint of before or after treatment. Most pateint were improved in 3 month. Conclusion: We have been thick that DVT in the lower extremity must done early diagnosis and choiced more massively intensively method of treatment and with only or combined oral anticoagulant therapy after operation was prevented for reccured and serious complication.

Background: The insertion of a nasogastric tube can be difficult in an anesthetized patient who has a cuffed endotracheal tube in place. The placement of a silastic nasogastric (NG) tube can lead to nasal bleeding or a submucosal dissection in the posterior pharynx. The aim of this study was to determine if the insertion of a nasogastric tube with a nasophryngeal airway can be made easy. Methods: Sixty patients were randomly assigned to one of two groups; Group 1 and Group 2. For Group 1, a nasogastric tube was inserted first. If this method was not successful with two consecutive attempts, then a nasogastric tube with a nasopharyngeal airway was inserted and if unsuccessful again with two attempts, then Magill forceps were used under laryngoscopy. For Group 2, a nasogastric tube with a nasopharyngeal airway was inserted first. If this method was not successful with two consecutive attempts, then a nasogastric tube was inserted and if unsuccessful again with two attempts, then Magill forceps were used under laryngoscopy. Results: The success rate of the 1st pass in Group 2 was significantly higher than in Group 1 (P < 0.05). The success rate with the 1st intended method in Group 2 was significantly higher than in Group 1 (P < 0.05). The rate of using Magill forceps was not significantly different between the two groups. Conclusions: The insertion of a nasogastric tube with a nasopharyngeal airway in anesthetized and intubated patients is effective in increasing success rate of insertion. Nasopharyngeal airway traverses the nasopharynx atraumatically and serves as a conduit for the smaller nasogastric tube. (Korean J Anesthesiol 2006; 50: 127~31)
