Bioethical Law(= Bioethics and Law) is a branch of law that make researches in legal implications as well as ethical implications of life science and biotechnology. The development of life science and biotechnology leads to some new enactments, for example, Bioethics and Safety Act 2004. Furethermore, it brings about changes of many existing law in general. Life science and biotechnology especially present urgent legal problems in major fields of civil law i.e. law of property, law of obligation, and law of status. Nowadays legal scholars and practitioner in civil law deal with hot issues resulting from the development of biotechnologies, for example, capacity of enjoyment of rights & legal capacity, nature of property as object of rights, validity of contracts, and damages suffered by torts. Moreover, the development of biotechnology has an effect on the most fundamental principle of civil law i.e. the principle of autonomy and key concepts including property, liability, consent, agency power etc. So basic legal institutions including ownership, dealings, damages should be revised and reconstructed in accordance with the developments of biotechnology and bioethical law.

This study aims that enlarging church and Christian's social order by analyzing conscious about social welfare services of a minister and Christian in urban and rural area. By this study, many Christian's has participation social welfare service negatively but people who have faith history, recognize that they force to intervene social welfare services like giving love, serve, relief to neighborhood is essential mission and duty of Church. Normal Christian think that shortage of minister's recognition is a big obstacle of social welfare service. However minister indicates financial problem. Christianity must educate Church that social welfare service is essential occupation and duty to the church, where release Christ Testment and share, sacrificing life to another.

Phenobarbital is a long-acting barbiturate causing generalized depression of neuronal activity in the brain. Its effect is primarily achieved through enhanced GABA-mediated synaptic inhibition. Its use as an antiepileptic agent was first described in 1912. Before the introduction of phenytoin, phenobarbital is used as sedative-hypnotics. It is used for the treatment of epilepsy and status epilepticus. All barbiturates, including phenobarbital, have a high potential for abuse. They were frequently used for suicide attempts in the past, but they have in large part been replaced by benzodiazepines. The onset of symptoms depends on the drug and the route of administration. Mild to moderate barbiturate intoxication resembles ethanol inebriation with slurred speech, ataxia, and lethargy. Severe acute barbiturate intoxication is life threatening. Early deaths are generally cardiovascular-related. Hypotension, shock, pulmonary edema, and cardiac arrest that occurs with large doses are caused by depression of central sympathetic tone and as well as by direct depression of cardiac contractility. The potentially fatal oral dose of phenobarbital is 6-10g. We describe an 23-year-old woman with pulmonary edema, and cardiac arrest ingestion of 18grams of phenobarbital. She was completely recovered by successful cardiopulmonary resuscitation and homoperfusion. We report a case with literature review.

The purpose of this study was to investigate the status of current nutrition labeling on the packaging of the processed foods that provide consumers with a reliable and consistent source of information, which has been considered as a useful aid for food selection and a potent educational tool for nutrition in daily life. The 2,160 processed foods purchased at the supermarket on September, 2002, were divided by food category issued from the 2002 food codes and assessed in the terms of the nutrition composition labeling and nutrition claims. Nutrition composition labeling was found on 356 of the 2160 processed foods items. Milk and dairy products had 49.7% of nutrition composition labeling, which was the largest number among the food category. Tables were most frequently used as the type of nutrition composition labeling(79.8%). Nutrition composition including many different ways of expression, such as a table of nutrition composition, indication of nutrition composition, analysis table of nutrition composition and comparative table of nutrition composition, made frequent use of nutrition composition labeling titles(78.7%). The various unit of measures were use in the nutrition labeling of the processed foods, per 100g or 100㎖ was the highest(44.6%) under the currently practiced nutrition labeling. The correct labeling standard with nutrient content and % RDA except energy, was used on 47.8% of labels, and those with only liability indication nutrient and liability indication nutrients plus discretion indication nutrients were 25.3 and 22.5% respectively. The processed foods with nutrition claims were 8.0%(172 items). Nutrients claims were divided in two ways: nutrient content claims and nutrient comparative claims. The most frequently used claims were contained in the former(44.4%) and more or plus in the latter case(16.3%). Ca was the most popular item as a nutrition claim nutrient(50.6%).

Abstract - In this paper, we propose a bidirectional mobile Ad Hoc routing protocol based on AODV(ad-hoc on-demand distance victor routing) with QoS(quality of service) support. At presence, wireless mobile communication focuses on how to efficiently support mobility of users more than QoS guarantee. However, in order to satisfy requirement of various applications which have been or will be served, QoS guarantee between end point is a very important issue. The existing AODV routing protocol is implemented to use only BE (Best Effort) service. However, actual wireless mobile environment requires to reduce a waste of communication resources and meet with the real-time change of data paths by setting up routes with QoS support, considering available communication resources at each node in advance. Therefore, in this thesis, we propose an adaptive QoS support method using hello message in order to rapidly meet with the change of available communication resources and to smoothly perform route maintenance. For performance evaluation, we analyzed the average date reception rate. At that time, we used evaluation parameters such as node's mobility -stop time, hello message period, and packet priority, considering the node's mobility and the number of best effort/QoS data flows. As results, we found that with our proposed method the average data reception rate was increased 16.3% for 0 mobility-stop second case and 4.7% for 300 mobility-stop second case.

Background: The goal of successful resuscitation is not only to stop the process of ischemia as soon as possible but also to overcome the secondary injury process after resuscitation, which involves a complex interplay of mechanisms. Brain damage accompanying cardiac arrest and resuscitation is frequent and devastating. Cells die by one of two mechanisms: necrosis or delayed neuronal death. Delayed neuronal death may require protein synthesis. Neurons in the CA1 subfield of the hippocampus are selectively vulnerable to death after injury by ischemia and reperfusion. Death of these neurons occurs after an interval of 1 or 2 days. We assessed the effects of a protein synthesis inhibitor, cycloheximide(CHX), on hippocampal neuronal death of rats by using the ventricular fibrillation cardiac arrest(VFCA) model. Methods: The effect of CHX(3 mg/kg, s.c.) on hippocampal neuronal death was studied in two groups of 18 rats each, one group being subjected to a 2-min VFCA and the other to a 3-min VFCA. Each group was divided into three subgroups: control(groupⅠ,Ⅱ) without subcutaneous injection of CHX, "esp-12" of group Ⅰ/Ⅱ treated with CHX 12 hours after return of spontaneous circulation (ROSC), and "exe-24" of group Ⅰ/Ⅱ treated with CHX 24 hours after ROSC. The coronal sections of the hippocampus levels were stained with hematoxylin-eosin after 72 hours of survival. The histologic damage score(HDS) was used to assign a score to the total number of damaged neurons counted in each of the hippocampal CA1 subfields. Results: 1. There were not significant differences in heart rates, blood pressures, blood sugar, and blood gas in group I & Ⅱ during the pre-arrest steady state or at 5 min and 30 min after ROSC. 2. In group I & Ⅱ, the HDS, were significantly reduced in rats(I exp-12, 1.1 ±0.6;Ⅰexp-24, 1.3 ±0.5;Ⅱ exp-12, 1.4±0.7; and Ⅱ exp-24, 1.8±0.8) treated with CHX 12 hours or 24 hours after ROSC than control rats(1,2.5 ±0.9;Ⅱ,2.9±0.8)(p<0.05). Conclusion: These results suggest that delayed hippocampal neuronal death from ischemic insult after ventricular fibrillation cardiac arrest followed by resuscitation can be prevented by a protein synthesis inhibitor, CHX. Further experimental studies of the action mechanism of protein synthesis inhibitors to delayed neuronal death and clinical applications are required.

Calcium carbide solution (30g/1 liter water) was applied to the center of pineapple (Ananas comous; cv Special Amarello) planted on May 23. 1985 at 30 ml per plant on May 21, June 11 July 2, July 23, August 13, and September 3, 1986 to determine effects of calcium carbide application date on floral induction, the number of days from the treatment to maturity, fruit size and weight of pineapple grown in plastic film house in Cheju province. The results obtained are as follows; 1. Calcium carbide application induced 87 to 100% flowering compared with 13% flowering of untreated plants. However, application date did not significantly affect flowering percentage of treated plants. 2. The number of days from treatment to inflorescence emergence was 65-91 days for plants treted on May 21 to July 23 and 219 and 232 days, respectively, for plants treated on August 13 and September 3. The number of days from treatment to inflorescence emergence was highly, negatively correlated with average mean air temperture (unit GDD-1), average daily minimum air temperature (unit GDD-2) or unit growing degree days (unit GDD-3) from treatment to inflorescence emergence. 3. The number of days from treatment to maturity was 228 to 236 days for plants treated on May 21 to July 23, and 351 and 359 days, respectively, for plants treated on August 13 and September 3. 4. Plant height and the number of active leaves per plant at maturity increased with delaying application of calcium carbide. 5.The number of suckers and slips per plant and crown length at maturity was decreased by application of calcium carbide and was not significantly affected by appliaction date of calcium carbide. 6. Penduncle length tended to decrease with delaying application of calcium carbide. 7. Fruit length and diameter, fruit weight and the number of fruitlets per fruit were greater for plants treated on from May 21 to July 2 than for plants treated on from July 23 to September 3.
