Purpose: The purpose of this study was to explore the chronic patients' preferences for care near the end of life. Methods: This is a descriptive survey research, with subjects of 161 outpatients with hypertension, diabetes mellitus or chronic renal failure. Results: The majority of the subjects do not want meaningless life sustaining treatment and they report thinking positively about family or health care professional to participate in their end of life decision making process. Subjects reported preferring adequate pain management and spiritual support at the end of life. In regard to advance directives (ADs), those subjects with chronic disease report thinking positively about the necessity of ADs and its institutionalization. However, the subjects report not having the detailed information on the proper time and method of writing their ADs. Conclusion: Based on these results, educational programs on end of life decision making for chronic patients need to be developed. Also, the nurse should try to reflect the opinion of chronic patients as much as possible when make an end-of-life decision.

Background： Tracheal resection and end-to-end anastomosis are the preferred treatment for tracheal tumor or tracheal stenosis. Absorbable suture material has been commonly used in case of tracheal anastomosis. But anastomosis technique is controversial. This experimental study compared between interrupted suture and continuous suture using Polydioxanone (PDS) absorbable suture material after tracheal resection and end-to-end anastomosis in rabbits. Methods : Twenty-four rabbits were used, divided into two groups of 12 animals each. The trachea was resected and then anastomosed with continuous 6-0 polydioxanone (PDS) (group 1), and intermittent 6-0 polydioxanone (PDS) (group 2). The animals were followed up for 6 months. Stenosis of the trachea was assessed at the time of death. Results : In two groups, anteroposterior diameter, transverse diameter, cross sectional area, and perimeter were greater in group 2 than in group 1 but, not significantly different. In addition, histologic findings were not different in two groups. Conclusions : This study suggest that stenosis after tracheal resection and end-to-end anastomosis using absorbable polydioxanone (PDS) suture material be not significantly different in both groups.

A total of 55 patients underwent surgical managements for postintubation tracheal stenosis from July 1975 through March 1997. All but 8 had received ventilatory assistance. The patients had S cuff lesions, 17 stoma lesions, 7 at both levels, 5 at subglottic lesions. Thirty two patients underwent the sleeve tracheal resection and end-to-end anastomosis. Five patients performed a wedge resection and end-to-end anastomosis. Twenty two patients received the Montgomery T-tube for relief of airway obstruction. Simple excision of granulation tissue was done in 7 patients. Rethi procedures(anterior division of cricoid cartilage, partial wedge resection of lower thyroid cartilage and T-tube molding) were performed in 2 subglottic stenosis patients. And the other subglottic patient was received permanent tracheal fenestration at 1975. The tracheoesophageal fistula patient was done sleeve tracheal resection and end-to-end anastomosis with interrupted double layer closure of esophageal fistula site. Cervical approach was used in 49 cases, cervicomediastinal in 13 cases and median stemotomy In 6 cases. Techniques for obtaining tension-free anastomosis included a cervical neck flexion(15-30$^{\circ}$) in all sleeve resection patients and laryngeal release in one. The length of resection was 1.5 to 5.0 on A total of 41 patients(74.5%) had good(24 patients) or satisfactory(17 patients) results. But in ten cases, the restenosis of anastomosis site which is the most common complication was developed Two of them underwent a second reconstruction and 8 patients required T-tube insertion for airway maintenance. Three patients(5.4%) died. The causes of death were tracheo-innominate artery fistula(2) and sudden obstruction of airway(1).

Superior hydrophilic properties will allow varieties of polyester(PET) fiber materials, fabrics and industrial materials a broader scope of use. The purpose of this study was to investigate the effect of water-absorbent softener treatment on the end-use properties and the hand of polyester knitted fabrics. Two different fabrics were knitted for the summer ladies' outwear; PET jersey and PET mesh. Variables were softner treatment and stitch type(jersey and mesh). Mechanical properties of the fabric samples were measured by KES-FB system. From these, primary hand values(HV) were evaluated by the conversion equation (KW-403-KTU) and the total hand value(T.H.V.) was calculated according to the KN-304 Summer. Both water-absorbent softner treatment and stitch types affected mechanical properties and hand values of PET fabrics. Mesh were thicker than single jersey stitch. As they became thicker, tensile, shear, and compressional energy increased. It appeared that coefficient of friction of mesh stitch was larger than that of single jersey stitch. The coefficient of friction and the mean deviation of surface roughness were decreased by softener treatment. After softner treatment KOSHI and SHARI of the both PET jersey and PET mesh decreased. However, FUKURAMI values of PET jersey increased and that of PET mesh decreased. The T.H.V. of the treated PET jersey was lower than that of the untreated one, while the T.H.V. of the treated PET mesh was higher than that of the untreated one. Overall T.H.V. of the single jersey was better than that of the mesh before and after softner treatment.

Objectives: This study was aimed to report changes in clinical symptoms and signs after treatment with Korean medicine in patients who suffered from calf edema due to deep vein thrombosis (DVT). Methods: A 46-year-old male patient, who discharged home after receiving standardized treatment for acute DVT in the right leg, suffered pain and heat sense due to edema of the affected calf. Oral administration of herbal medicine (Gyejibongnyeong-hwan 4 g, twice daily) and acupuncture therapy were given to him for 6 weeks. The change in chief complaints, Villalta score, the right and left side difference of the circumference and the skin surface temperature of both calves, and blood level of D-dimer were observed before and after treatment. Results: The patient's chief complaints began to significantly improve from 2 weeks after treatment, and disappeared completely within 4 weeks. At the end of the treatment, a substantial decrease in the difference between the right and left calves in the circumference and skin surface temperature was observed. This effect was maintained even at the time of follow-up 3 months after the end of treatment, and the patient completely recovered indoor and outdoor life to the level before onset. Conclusions: This case suggests that Korean medicine treatment, including Gyejibongnyeong-hwan administration and acupuncture therapy, can be a viable option to improve edema and related clinical problems in the affected limbs due to DVT.

The rolling process is an efficient and economical approach for the manufacturing of plate metals. In the rolling process, the temperature variation is very critical for plate thickness accuracy. The main cause of thickness variation in hot plate mills is the non-uniform temperature distribution along the length of the slab. Also the exit plate thickness is mainly affected by the rolling conditions such as mill modulus, plate thickness and plate width. Hence the thickness variation in top-end is also dependent on these factors. Therefore this study has concentrated on determining the correct amounts of thickness variation due to top-end temperature drop and process parameters.

The RK-temperate phage which infected with Bacillus cereus was isolated and the characters were investigated. The induction of RK-temperate phage from host bacterium attained by ultraviolet light irradiation (15W, 30cm, 30-120sec) and mitomycin C treatment (0.2-2 ug/ml). The host range of RK-temperate phage was not revealed with lysogenic and related strains of B. cereus. But B. cereus(PS) 352 which obtained by N-nitrosoguanidine treatment (1,000{$\mu}g/ml)$ to phage infected with host bacteria was sensitive bacteria of RK-temperate phage. RK-temperate phage was stabilized at the condition of nutrient broth (pH 7-8), Tris-buffer (pH 7-8) and ammonium buffer (pH 8-9) and Sorensen's phosphate buffer (pH 6-7), but unstabilized at other salt solutions and pH range. Also, thermostability was to $45^{\circ}C$ but unstabilized at above $50^{\circ}C$. At RK-temperate phage, the measurment values of head, neck, mid tail and end tail were 59nm, $9{\times}16nm,\;10{\times}189nm,\;and\;10{\times}14nm$ respectively. The morphology of head was regular polyhedron, and the end tail was coneate form. On the one hand, the number of capsid protein layer of tail were consist of 4, 35, and 1 at neck, mid tail, and end tail, respectively. RK-temperate phage was identified with DNA phage and G+C contents were 38.63. The latent time of RK-temperate phage was 30 minutes and the burst size was 70-80. And the host bacteria was lysed in case of multi-infection, above moi 1.

We investigated compensatory growth of Nile Tilapia Oreochromis niloticus in structural size and live weight in response to different deprivation periods and refeeding. Four treatments were assigned randomly to fish in 12 glass tanks, with each treatment performed in triplicate. The control group was fed to satiation three times a day throughout the experiment. The other three treatment groups were starved for 1 week (S1), 2 weeks (S2), or 4 weeks (S4) and then fed until the end of the experiment. After the experiment, no significant differences were observed among S1, S2, and the control group in average weight or length, whereas the weight and length of S4 were significantly reduced. Relative condition factors of the three starved groups decreased significantly until the end of the restricted period but recovered rapidly after refeeding. The specific growth rate in weight ($SGR_W$) of the three restricted groups recovered quickly upon refeeding and were significantly higher than the control group, but these differences disappeared gradually until the end of the experiment. No significant difference in specific growth rate in length ($SGR_L$) was noted between the control group and the three restricted groups after refeeding. All three groups showed hyperphagia for a short period upon refeeding, and no statistical differences were observed in feeding efficiency among the four groups.

This study is to observe the occurrence of heterotrophic bacteria in terms of free chlorine residuals in two different water distribution system which belongs to both K and Y water treatment plant of S city of Korea. The data analyzing in distribution systems (DS) shows that the free chlorine residuals decrease from 0.10 to 0.56 mgmg/L for K, and 0.51 to 0.78 mg/L for Y. The decay of free chlorine is clearly higher in both March and August than those of in January. The HPC in DS are ranged from 0 to 40 CFU/mL for K, 0 to 270 CFU/mL for Y, on R2A medium. In particular, its level is relatively high at consumers ground storage tanks, taps and point-of-end area of Y. The predominant genera is studied in distribution systems are Acinetobacter, Sphingomonas (branch of Pseudomonas), Micrococcus, Bacillus, Staphylococcus. The diversity of heterotrophic bacteria increase in the end-point area. Most of them are either encapsulated cells or cocci of gram-positve. In conclusion, the point-of-end area in distribution systems shows the longer flow distance from water treatment plants, the greater diversity and higher level of heterotrophic bacteria due to the significant decay of free chlorine residuals.

Depression is common in patients with end-stage renal disease(ESRD) and has a negative effect on the quality of life, functional ability, and mortality of the patients, with a prevalence rate as high as 20-25%. Especially, the increasing tendency of mortality in ESRD patients is associated with recent or current depression, and the suicide rate is also increased by depression in patients with ESRD. Therefore, accurate detection and appropriate treatment of depression is very important in ESRD patients. Also, a deferential diagnosis is needed concerning uremic symptoms and depression in ESRD patients. However, there has been little data so far particularly in terms of randomized clinical trials. This review focused on the recent knowledge of depression in ESRD, and could encourage clinical study and trials in this field.
