The purpose of this study was to present basic data in the nursing practice for the management of living kidney donor by understanding the nature and meaning of kidney donors, experiences. The research subjects were 11 living kidney donors who had donated from Mar 1991 to Feb. 1994 and discharged from the 3 hospitals in Pusan. Data has been collected by Intensive interview with donors. The data analysis has made by phenomenological method of Van Kaam for understanding the phenomenon and meaning of their experiences. The experiences of kidney donors were analyzed into the 4 situations, that is,'motivation of kidney donor', 'decision time to make kidney donation', 'pre-opperation','after donation'. The descriptive expression and common elements were drawn from original data of each situation on the basis of subjects' own words. From each situation, the com-mon elements of kidney donors' experiences were integrated, summarized and described as follows 1. Motivation of kidney donation They wanted to donate their kidney because of empathy of pain on the groung of love to the recipient and with exppectation of successful kidney transplant or as a solution of economic difficulty. 2. Experiences in deciding to make kidney do-nation In deciding to make kidney donation, donors had love toward the recipients. But they experienced conflict too. 3. Experiences before being operated on donated kidney In experiences from deciding to make kidney do nation to preoperation, donors had love toward the recipients. But they also felt anxiety or dissatisfaction. Therefore, they controlled their mind by their faith, support of medical staff or support of society. And they experienced regret for the sociological cognition or financial apprehension. 4. Experiences after kidney donation After kidney donation, donors experienced satis-faction and accompplishment in spite of mental and physical discomfortness, while they felt sense of loss / disappointment, repentance, regret, and apprehension of progress toward their condition. Thus, kidney donors donated their kidney on the ground of empathy and love to the recipient and with expectation of successful kidney transplant. But during the process of kidney donation, they ex perienced conflict, love, anxiety, regret, apprehension of economy. And after donation, they felt sense of satisfaction and accomplishment, while they felt sense of discomfortness, loss / disappointment, re-gret, repentance, or apprehension of progress toward their condition. This result contribute to nurses' role not only for the management of living kidney donors but also for the management of cadaver donors' family.
This study examines ERPT with asymmetric response and both import and export market shares, using wool trade data. The study found that, asymmetric response may be as common as symmetric response. In addition, the responses (both in price and quantity demanded) to the changes in exchange rate are considerably different across goods, and even for the homogenous goods, across countries. In case of depreciation, the export price changes more than appreciation case in general, and as a result the destination price changes less. It is also found that the cases of excessive or perverse pass-through are found more frequently than reported by previous studies. This finding points out that strategic behavior of firms or unexpected response to exchange rate fluctuation takes place more frequently than we commonly expect or take, in particular at disaggregated levels. When the model considers asymmetric responses of the export price to appreciation and depreciation (of exporter's currency), the estimation provided that for 39 trade cases out of 83, export price responded to appreciation and depreciation in different fashions, although the normal response was the dominating phenomenon with 99 cases or about 60% out of 166 cases. Market shares affected the extent and direction of responses in select cases. These findings will have important implications for policy makers and traders.

Results of an experiment on the behavior of rats and mice in order to explore the possible pharmacological actions of Panax ginseng upon the central nervous system can be summarized as follows: 1. Spontaneous motor activity. In the case of mice, those groups who were administered 2.5 mg and 5.0mg of ginseng saponin per kilogram of body weight were observed to have increased their activity compared with the control group, while the 50.0 mg and 100.0 mg per kilogram body weight groups demonstrated lower levels of activity, with the peak of activity appearing at 30 minutes after administration of drugs. In the case of rats, those groups of animals who were given injections in the dosage of 2.5 mg, 5.0 mg and 50.0 mg per kilogram body weight demonstrated higher activity than the control group, while the 100.0 mg per kilogram group appeared to have decreased in their activity, with the peak action appearing 30 minutes after the administration of ginseng saponin. The 50.0 mg per kilogram group demonstrated no significant differential. 2. General behavior analysis. In the case of mice, decrease in sleeping component of behavior and increase in the walking and roaring components, compared those with the control group, turned out to be a common phenomenon among the groups who were administered 2.5 mg, 5.0 mg and 50.0 mg of ginseng saponin per kilogram body weight, with the 5.0 mg per kilogram group standing out of all the other groups in terms of their reactions. In the case of rats, ginseng saponin appeared to reduce sleeping component with 2.5 mg, 5.0 mg and 50.0 mg per kilogram body weight groups, while increased the walking and rearing components. It was observed that administratoin of ginseng saponin in a dose of 2.5 mg per kilogram appeared to markedly increase the lying and grooming components of animal behavior. 3. Open-field exploratory behavior. Adminstration of ginseng saponin to mice in doses of 5.0 mg, 50.0 mg and 100.0 mg per kilogram body weight decreased activity, but increased their exploratory behavior. In the case of rats, however, administration of ginseng saponin in the doses of 2.5 mg and 5.0 mg per kilogram body weight markedly increased their activities, while decreased activities with the 50.0 mg per kilogram and 100.0 mg per kilogram groups. The exploratory behavior of rats appeared to have decreased, while grooming increased ramarkably. 4. The above findings from a series of experiment appear to suggest a stimulating effect on the central nervous system when ginseng saponin is administered in small doses, but that larger doses might result in an inhibitory effect, though differential results can be anticipated with modification of experimental conditions.

It is common to analyze volatile organic compound (VOC) or semi-VOC (SVOC) in a sample composed of a complex matrix consisting of multiple components such as bloods through a separation process. Adsorption is a physical phenomenon in which certain components accumulate on the surface of other phases. In order to overcome difficulties in the pretreatment process, an adsorption is frequently used. Solid phase microextraction (SPME) equipment with porous carbon carboxen (CAR) is an example of adsorption application. In this study, the adsorption of 4-octylphenol to carboxen was examined. To do so, the extraction efficiency for such solvents as dichloromethane ($CH_2Cl_2$, DCM), ethylacetate ($CH_3COOC_2H_5$, EA) and diethylether ($C_2H_5OC_2H_5$, $Et_2O$) was studied and also the derivatization reaction for 4-octylphenol with reagents of bistrimethylsilyltrifluoroacetamide (BSTFA), methylchloroformate (MCF) and pentafluorobenzylbromide (PFBBr) was compared. The combination of DCM and BSTFA showed good performance thus they were adopted for this study. Thermodynamic adsorption experiments showed that the adsorption process was endothermic and Freundlich isotherm equation was more suitable than Langmuir isotherm. It was also found that the adsorption followed a pseudo-$2^{nd}$ order kinetic model.
In a variety of eukaryotic cells, autophagy sequesters a portion of the cytoplasm and targets it to a lytic compartment for degradation in bulk. Autophagy is a dynamic process for degrading cytoplasmic cargoes with various degrees of selectivity, and its activity is tightly regulated in a nutrient- and development-dependent manner. Autophagy research has drawn much attention since autophagy not only is an interesting cell biological phenomenon but also has great potential for medical and agricultural applications. For example, autophagy is associated with cancers and neurodegenerative diseases in human and mammalian cells and is also suggested in remobilization of nutrients during the senescence of plant leaves. In this general review, we describe genetic components of the core autophagic machinery conserved among yeast, animals, and plants and briefly explain how these components are responsible for major steps in plant autophagy. We discuss four common features of autophagic processes: (i) autophagy as a degradation pathway, (ii) the concept of flux in autophagy research, (iii) dependency on developmental and nutritional cues, and (iv) diversity of autophagy, focusing on selective types of autophagy. We also summarize cell biological and physiological functions of plant autophagy. Our intention is to provide a quick guide to autophagy for those who are new to autophagy research.
According to recent rapid price drop and capacity growth of main memory, the number of applications on main memory databases is dramatically increasing. Cache miss, which means a phenomenon that the data required by CPU is not resident in cache and is accessed from main memory, is one of the major causes of performance degradation of main memory databases. Several cache-conscious trees have been proposed for reducing cache miss and making the most use of cache in main memory databases. Since each cache-conscious tree has its own unique features, more than one cache-conscious tree can be used in a single application depending on the application's requirement. Moreover, if there is no existing cache-conscious tree that satisfies the application's requirement, we should implement a new cache-conscious tree only for the application's sake. In this paper, we propose the cache-conscious generalized search tree (CC-GiST). The CC-GiST is an extension of the disk-based generalized search tree (GiST) [HNP95] to be tache-conscious, and provides the entire common features and algorithms in the existing cache-conscious trees including pointer compression and key compression techniques. For implementing a cache-conscious tree based on the CC-GiST proposed in this paper, one should implement only a few functions specific to the cache-conscious tree. We show how to implement the most representative cache-conscious trees such as the CSB+-tree, the pkB-tree, and the CR-tree based on the CC-GiST. The CC-GiST eliminates the troublesomeness caused by managing mire than one cache-conscious tree in an application, and provides a framework for efficiently implementing arbitrary cache-conscious trees with new features.
From the mid-1980s '91s, remarkable Ethnicism and Primitivism in the Europe fashion trend could be represented as an exotic taste longing for secenery and emotion of non-europe area in the West. These phenomenon could be found out in connection with Acculturation, which means when two different cultures or more were contacted they were identified or merged in process of diffusion and change of them. This point of view was the culture anthropologic one that make a comparison and analysis of sameness and difference between cultures. The purpose of this study was to illuminate exotic taste represented in costume in the cluture-anthroplogic aspect, to compare with beauty of costume that each culture of costume and the meaning of the times due to those differences. an aspect of the exotic taste and character in the western costume that was inspected by dividing into 'Primitivism', 'Oriental element' and 'the element of a national costume in the East European bloc ' were as follows; First, Primitivism had something in common with what was pursued in the trend of Modern Art, through the late 19th century to the early 20th century. In fashion fettered by technique, the creation expressed in a free was and showed simple beauty of costume. At the same time, pure emotion expression, creative power and witty strong expression give the cognition of transcendency breaking the routine and the cognition of complexity of an included conception. Those are garments showing not only the primitive thought and mysticism but a fancy, an abstraction, and a life. Colors and accessaries which described nature and matched simple costume composition to the expression of various material or patterns transmitted the image of the primitive strongly. Second, "Drental element" which had an effect on western custome historically in a long time had outstanding luxurios adornmental beauty of custome. Extending from the Arab stated India, China, Korea, Japan, each national costume with a gay national culture became one of motif. Various ornamental factors expressed on Trapez Line, Sime Line and Drape, or Raied style, which did not restrict the body. Those were not only functional Easy Look, but were also satisfying human's ornamental desire. Third, national factors in the East European bloc are theme that begins to be embossed in the late 80's. In view of a political change and cultural situation with a double character of Europe and Orient, it was estimated that national factors have great importance in fashion. Item concerned with new concern appeared at Autumn & Winter collection. It shows elegant and graceful beauty of costume by adding a fur or jewel to simple form. These national factors in the East European bloc are simple form, but shows the difference in more cubic formation than form expressed in Primitivism or Oriental factors Exotic taste appeared form 80's to 91's, is thought to create an forgotten romantic emotion and traditional fashion

A two-phase (gas-liquid) flow is a common phenomenon in fluidic systems, e.g., fluidic systems in the electro-magnetic or nuclear power generation industry and in the steel industry. The measurement of a two-phase flow is important for guaranteeing the safety of the system and for achieving the desired performance. The measurement of the void fraction, which is one of the parameters of the two-phase flow that determines the pressure drop and heat transfer coefficient, is very important. The time resolution achieved by employing the impedance method that can be used to calculate the void fraction from the impedance of the fluid is high because the electric characteristics are taken into account. Therefore, this method can be employed to accurately measure the void fraction without distortion of flow in real time by placing electrodes on the walls of the tubes. Coney analytically studied a ring-type impedance meter, which can be employed in a circular tube. The aim of this study is to experimentally verify the robustness of a three-ring impedance meter to variations in the electric conductivity of the fluid; this robustness was suggested by Coney but was not experimentally verified.
Purpose: Presently, silicone rubber is chosen most frequently for nasal augmentation. However, there is a possibility of extrusion with this material. Sometimes, noses are prone to be traumatized, and then silicone rubber has a possibility of deformity or deviation resulting in trauma. We experienced cases with complications and traumatic deformities after the augmentation rhinoplasty. Methods: A retrospective review was performed to determine the characteristics of the implanted nasal silicone prosthesis after trauma. The patients' data such as deviation of implant, shape of fracture, age and sex of the patient, time of treatment, operative methods were reviewed. From March 2001 to March 2008, this study was performed in 30 patients. The patients were 25 females and 5 males, from 24 to 60 years of age, with an average of 42. All patients had previous augmentation rhinoplasty with silicone implant. Results: All of the 30 patients were confirmed as deviation of silicone and nasal bone fractures in the facial bone CT scan. The most common cause of fracture was traffic accident. The classification of nasal trauma after augmentation was done by facial bone CT. Class I: Deviation of silicone without nasal bone fracture without extrusion(12 cases, 40%), Class II: Deviation of silicone without nasal bone fracture and with extrusion(4 cases, 13%), Class III: Deviation of silicone with nasal bone fracture and without extrusion(8 cases, 27%), Class IV: Deviation of silicone with nasal bone fracture and with extrusion(3 cases, 10%), Class V: Mild deviation of silicone with nasal bone fracture(3cases, 3%). Specially, the comminuted or trapezoid nasal fracture was confirmed in 11 cases(Class III, IV). Conclusion: The problems of silicone implant have generally been related to foreign body reactions, rigidity of the material, encapsulation, infections, and extrusion. We experienced 11 cases of comminuted or comminuted trapezoid shaped fracture below nasal implant. So, we think this phenomenon could be used in late problem of silicone implant.
Sternal fractures, once thought of as an uncommon phenomenon, have occurred with an increasing frequency, paralleling the incidence of motor vehicle accidents. The tremendous force necessary to cause sternal fracture and this bone's prominent position overlying major intrathoracic and mediastinal structures, have important implications in the assessment and treatment of patients. This evaluation is based on the review of 72 patients of traumatic sternal fracture treated at the Department of Thoracic and Cardiovascular Surgery, Seoul Adventist Hospital during the last 4 years from March 1993 to February 1997. The frequency was 12.2% of nonpenetrating chest trauma and average age was 43.2 years old. Automobile accidents(84%) and sternal body fractures(95.8%) with anterior displacements(19.4%) was the most common cause and fracture site. Increase of cardiac isoenzymes was more frequent and higher in sternal fracture than chest contusion but there was no relationship between the time to take normalization of them and the mode of trauma.
