Purpose: The ability to concentrate urine becomes an important index in determining nocturnal enuresis (NE) treatment. The aim of our study was to investigate first-morning urine osmolality (Uosm) changes at the end of treatment compared to before treatment in children with NE. Methods: A total of 71 children with NE were divided into two groups according to the level of first-morning Uosm before treatment: high group (≥800 mOsm/kg) and low group (<800 mOsm/kg). Baseline parameters were obtained from uroflowmetry, frequency volume charts for at least 2 days, and a questionnaire for lower urinary tract symptoms. All patients were basically treated with standard urotherapy and medication. The first-morning Uosm was measured twice, before treatment and at the end of treatment. Results: The response rate was higher in the low group after 3 months of treatment than in the high group (P=0.041). However, there was no difference between the two groups at the end of the treatment. In the high group, the first-morning Uosm at the end of treatment did not show a significant change compared to before treatment. In contrast, the first-morning Uosm increased in the low group at the end of treatment (P<0.001). However, it was still lower than that of the high group (P=0.007). Conclusions: The ability to concentrate nocturnal urine improved at the end of treatment compared to before treatment in the low Uosm NE children. In addition, NE improved faster in the low Uosm group before treatment than in the high group.

Between 1985 and 1990, 41 patients underwent treatment of the tracheal stenosis. Nineteen patients underwent resection and end-to-end anastomosis including three cases of the subglottic stenosis. Other patients had had treatment such as LASER therapy, bronchoscopic removal, insertion of the Montgomery silastic T-tube or stent insertion Nineteen patients which underwent resection and end-to-end anastomosis were excellent result from three years to sixth months. Other patient were followed at OPD for the other complication or restenosis. There were no hospital death but one patient was managed by bronchoscopic removal of the granulation tissue and other one patient had underwent reoperation for the dehiscence at the anastomotic site.

Clavicle medial end fracture is rare, and it has not been studied extensively. Although there is debate regarding its treatment methods, because of the complications of conservative treatment, surgical treatment has been considered more than conservative treatment. This study describes a surgical method using double-plate fixation for treatment of clavicle medial end fractures in which plates were used on each anterior and superior border according to the anatomical structure of the clavicle. In addition, we report operative results of three patients treated by double-plate fixation.

Purpose: In 2018, the Act on Decisions on Life-Sustaining Treatment for Patients in Hospice and Palliative Care or at the End of Life was implemented and the scope of official recognition for terminally ill patients was expanded. The purpose of this study was to investigate the decisions made by patients with end-stage liver disease about their life-sustaining treatment in a clinical setting. Methods: The subjects of this study were patients with end-stage liver disease hospitalized at a tertiary hospital in Seoul, Korea who wrote physician orders for life-sustaining treatment (POLST). Data collection was done using patients' electronic medical records, and a retrospective analysis of POLST was conducted. Results: Among 101 patients, 18.8% were female and 81.2% were male, and their mean age was 61.8 (±10.61) years. Sixty-three patients (62.4%) wrote their POLST by themselves. Three patients withdrew the POLST, of whom two did so for liver transplantation, and one did so for chemotherapy. Conclusion: This study shows that sufficient consideration of liver transplantation is needed for end-stage liver disease patients before making decisions on life-sustaining treatment. The self-determination of patients must be respected and effective guidelines are urgently needed.

An experiment was conducted for 20 days( from July 21 to August 10, 1996) to investigate the differences in thickness of eggshell and eggshell membrane in Korean native chicken. All the eggs were purchased from a farm located in Chinju area. All eggs were categorized into Treatment I (34.89~51.39 g), H (53.32~60.70 g), and III (34.89~60.70 g) according to their weights. Eleven items were measured in all three treatments, i.e., egg weight, egg length, egg width, breaking strength, eggshell thickness of large end(STLE), eggshell membrane thickness of large end(SMTL), eggshell thickness of small end (STSE), eggshell membrane thickness of small end(SMTS), eggshell thickness of middle part(STMP), and eggshell membrane thickness of middle part(SMTM). Correlation coefficients between egg weight and eggshell weight, among eggshell thickness of large end, small end and middle end and eggshell weight were significant (P<0.01). Correlation coefficients between egg weight and large eggshell membrane were nega-tively significant(P<0.01). Breaking strengths were higher in Treatment I than in Treatment H. Correlation coefficients among thickness of eggshell and eggshell membrane at each point at 3 parts of large end, small end and middle end were not significant.

Since the end treatments of guardrails installed on domestic roads have the shapes which can easily penetrate and turnover a vehicle, the occupant can be subjected to severe injury when a vehicle impacts the end treatments. In this study, the criteria of performance evaluation for end treatments are suggested which are suitable to domestic road circumstances. Based on the investigation for the installation and studies instances of end treatments, the mechanism of end treatments is examined and the new end treatment suitable to domestic road circumstances is suggested. The suggested end treatment was verified by computer simulation using d LS-DYNA programs and satisfied the suggested performance evaluation criteria for end treatments. And the developed end treatment was verified by full-scale vehicle crash test and satisfied the following three primary appraisal factors of the suggested performance evaluation criteria for end treatments; occupant risk criteria, structural adequacy, and after-collision vehicle trajectory. This study is the first to develop end treatments considering the occupant safety in Korea. Therefore, If the developed end treatments is installed on roads and highways, it can be expected that it will reduce the grave situation of end treatment accidents and increase the safety of roads.

This study was conducted to investigate the effects of End-coating (CO) treatment and Vapor-dam (V) treatment on the air circulating oven drying characteristics of green stock (Paulownia tomentosa) for drum. The reduction of the weight of specimens was greatly displayed in order of control (C-NC) treatment, End-coating (C-CO) treatment, Vapor-dam (V-NC) treatment and Vapor-dam/End-coating (V-CO) treatment after the beginning of drying. The V-CO treated specimen showed smoother temperature gradient compared with the V-NC treated specimen throughout whole drying stage and there was little temperature gradient between the inner and outer part of the cylindrical stock. The C-CO treated specimen showed higher value of vapor pressure in both the inner and outer part of the cylindrical stock until the middle stage of drying, while after the middle stage of drying only the inner part of the cylindrical stock presented higher value compared with the C-NC treated specimen. The distribution of the absolute vapor pressure of the V-CO treated specimen was similar to that of the V-NC treated specimen during the initial stage of drying. However, the former showed a large distribution in order of the hollow, the outer part, the inner part of the cylindrical stock after the initial stage of drying, which was entirely different model of distribution from that of the V-NC treated specimen. Surface checks and ring failures were not observed for all of the specimens, while end checks were severely occurred for the C-NC treated specimen and the V-NC treated specimen.

Purpose: The Act on Hospice and Palliative Care and Decisions on Life-Sustaining Treatment for Patients at the End of Life came into force in February 2018 in Korea. This study reviews the practices of end-of-life care for patients who withdrew or withheld life-sustaining treatment at a tertiary care hospital, addresses the limitations of the law, and discusses necessary steps to promote patient-centered self-determination. Methods: We retrospectively analyzed the medical records of patients who died after agreeing to withhold life-sustaining treatment in 2018 at our university hospital. The cause of death, the intensity of end-of-life care, and other characteristics were reviewed and statistically analyzed. Results: Of a total of 334 patients, 231 (69%) died from cancer. The decision to stop life-sustaining treatment was made by family members for 178 patients overall (53.3%) and for 101 (43.7%) cancer patients, regardless of the patient's wishes. When the patient decided to stop life-sustaining treatment, the time from the authorization to withhold life-sustaining treatment to death was longer than when the decision was made by family members (28.7±41.3 vs 10.5±23.2 days, P<0.001). Conclusion: In many cases, the decision to discontinue life-sustaining treatment was made by the family, not by the patient. In order to protect human dignity based on the patients' self-determination, it is necessary for patients to understand their disease based on careful explanations from physicians. Ongoing survey-based research will be necessary in the future.

As population aging increases the burden of cancer, the quality of death of patients with cancer is emerging as an important issue alongside their quality of life. To improve the quality of death, it is necessary to prepare for death, allowing patients to die comfortably and with dignity at the end. Considering these issues, I aim to discuss the practical aspects of notifying the patient of the terminal phase of cancer and planning for end-of-life care (i.e., advance care planning). When cancer treatment that can extend the patent's lifespan becomes difficult, the patient enters a treatment transition period. Treatment is shifted from life-prolonging care to life-enhancing care, and end-of-life care must be well planned. Medical providers often worry too much about whether the patient will be disappointed or psychologically traumatized when notified of the terminal phase of their cancer, thus delaying plans for end-of-life care. In fact, patients can accept their condition and prepare for end-of-life care better than we expect. During the treatment transition period, notification of terminal status should be given, and a well-prepared advance care plan should be established early when the patient has decision-making ability. In addition to conveying information, it is always necessary to be sensitive to whether the patient and caregiver understand the information and respond to their emotions.

Endodontic surgery is a procedure to treat apical periodontitis or abscess in cases that did not heal after nonsurgical treatment or retreatment. This might include situations with persistent intracanal infection after root canal treatment. Other reasons might be found in extraradicular infection, such as bacterial biofilm on the apical root surface or bacteria within the lesion. For many years, the treatment standard was the traditional approach with surgical burs and amalgam for root-end filling. Endodontic microsurgery is the most recent step in the evolution of endodontic surgery, applying not only ultrasonic tip and biocompatible filling materials but also incorporating high-power magnification and illumination. Although many studies have been published that advocate the use of modern technique, the traditional techniques are still widely used in the surgery community. The purpose of this study was to demonstrate the endodontic microsurgery procedure including the root-end preparation and filling with the use of a surgical operating microscope.
