Three varieties of taro flours (Altoran, Josaengjong, and Jaeraejong) were analyzed to evaluate their nutrient composition and physicochemical properties. Moisture contents of the three taro cultivars varied from 5.74-10.30%. Among the three cultivars, Altoran flour had higher protein and fat contents than other cultivars. There were 17 kinds of amino acids in the three taro flours. The major fatty acids in the three taro flours were linoleic acid (46.5-51.4%), palmitic acid (21.7-25.8%), and oleic acid (12.3-18.7%), and two thirds of the total fatty acids were unsaturated fatty acids. Potassium, phosphorus, magnesium, and calcium were the most plentiful minerals in the three taro flours, and the free sugars were glucose, fructose, and sucrose. The total dietary fiber contents of the three taro flours ranged from 12.97 to 17.60%. From these results, Altoran contained a high level of dietary fiber, minerals, essential amino acids, and free sugars. Jaeraejong showed the highest water absorption index. The water soluble index of Altoran was higher than that of the other cultivars. From the differential scanning calorimeter results, the gelatinization temperatures of the three taro flours were $84.98-89.91^{\circ}C$. The pasting temperature of the three taro flours was from 46.77 to $49.30^{\circ}C$ by rapid visco-analyzer. Among these varieties, Josaengjong had the highest peak viscosity and final viscosity, whereas Altoran had the lowest. These taro cultivars are expected to be potential material for application in taro processed foods, due to their gelatination and pasting properties.
Quality characteristics such as alcohol, acid, and sugar contents of takju brewing mashes prepared using several yeasts were investigated during 12-days of fermentation. Among the yeasts examined, S. cerevisiae led to the highest level of ethanol (10.2-13.4%) and total minor alcohols (0.729-0.831 mg/mL). Regardless of the yeasts used, the acidity showed drastic changes (pH from 3.4-4.2 down to 2.4-2.7) during the first 2 days, and displayed negligible changes from day 4. The total acid contents rapidly increased to the first 4 days of fermentation and leveled off from 4 to the end of fermentation period. The common organic acid components were lactic, succinic and acetic acids. The total and reducing sugar contents varied depending on the yeasts used, with mashes prepared using S. coreanus and S. rouxii producing the maximum total sugar contents (5.43-5.5%) at the end of fermentation. The reducing sugar showed its maximum (7.53-14.89%) at day 2, after which it decreased to its minimum levels (3.04-4.52%). The common free sugar components were glucose and fructose, while S. ellipsoideus led to a higher free sugar level (0.35-5.29%).
Purpose : This study aimed to investigate and to evaluate the present conditions of hospice programs in Korea for supplying data useful in making policy in hospice, which is not institutionalized yet. Method : For this purpose we surveyed 59 hospice programs regarding the general characteristics, manpower, patients, services, financial conditions, and facilities. Thirty-seven hospice programs answered the questionnaires. Result : They were 11 tertiary hospitals, 11 other hospitals, 3 clinics, 12 home care hospice, and 1 freestanding hospice. Only 9 hospice programs have all of the essential professionals: physicians, nurses, social workers, clergies, and volunteers. In some hospice programs, volunteers who had not been trained for hospice provided services to terminal patients. More than half of the hospice said they provided services to the patients who lost their consciousness and were not suitable for hospice care. 16% of the hospice said they did not keep the patients' record. Some hospitals including tertiary hospitals provided such intensive care as radiotherapy, TPN, injections to hospice patients. Many hospice programs other than hospitals didn't charge patients for hospice care. 60% of the hospice said they suffered from financial problems. Most of the hospice wards were not built for hospice use at first. So they did not have such supplementary facilities as dayroom, waiting room, special bathing facilities etc. Conclusion : For improving the quality of terminal patients and promoting the cost effective use of health care resources, it is necessary to consider the institutionalization of hospice. The institutionalization of hospice programs can improve the quality of hospice care and the standardization of the hospice program can hasten its institutionalization.

Purpose: The prevalence of lung cancer is increasing continuously these days. We studied clinical characters of the terminal lung cancer patients who had died in hospice units and our study is the basic report for efficient hospice and palliative care to the lung cancer patients. Methods: We retrospectively reviewed the medical records of 129 terminal lung cancer patients who had died in Sam Anyang Hospice Unit from March 2003 to December 2006. The survival days during the hospice and palliative care were analyzed using Kaplan-Meier method of SPSS 13.0. Results: There were 93 males (72%) and 36 females (28%), and median age of patients was 68 years (range $37{\sim}93$). Eighty two patients (64%) took analgesics, the others 47 (36%) not. The most prevalent reason for admission was dyspnea (47 patients, 36%) and it was different from the terminally ill cancer patients being hospitalized because of pain. And the most common symptom was general weakness (103 patients, 80%). One hundred twenty of the paitents (93%) were administered opioid analgesics, and IV morphine shots were mostly used (103 patients, 80%). Sedation was used in 87 patients (67%), and midazolam was mostly used (68 patients, 53%). The median survival in hospice and palliative care was 35 days and the median hospitalization was 24 days. Conclusion: It is very important to manage dyspnea in terminal lung cancer patients. The length of hospice and palliative care for the terminal lung cancer patients is still short. Therefore continuous education and promotion of hospice and palliative care is needed for an effective care for the patients, their families and doctors.
Purpose: Recently, health policy making is increasingly based on evidence. Therefore, Korean Terminal Cancer Patient Information System (KTCPIS) was developed to meet such need. We aimed to report its developmental process and statistics from 6 months data. Methods: Items for KTCPIS were developed through the consultation with practitioners. E-Velos web-based clinical trial management system was used as a technical platform. Data were collected for patients who were registered to 34 inpatient palliative care services, designated by Ministry of Health, Welfare, and Family Affairs, from $1^{st}$ of January to $30^{th}$ of June in 2009. Descriptive statistics were used for the analysis. Results: From the nationally representative set of 2,940 patients, we obtained the following results. Mean age was $64.8{\pm}12.9$ years, and 56.6% were male. Lung cancer (18.0%) was most common diagnosis. Only 50.3% of patients received the confirmation of terminal diagnosis by two or more physicians, and 69.7% had an insight of terminal diagnosis at the time of admission. About half of patients were admitted to the units on their own without any formal referral. Average and worst pain scores were significantly reduced after 1 week when compared to those at the time of admission. 73.4% faced death in the units, and home-discharge comprised only 13.3%. Mean length of stay per admission was $20.2{\pm}21.2$ days, with median value of 13. Conclusion: Nationally representative data on the characteristics of patients and their caregiver, and current practice of service delivery in palliative care units were obtained through the operation of KTCPIS.
Purpose: End-of-life (EoL) decisions are challenging and multifaceted for patients and physicians. This study was aimed to explore how EoL care is practiced for patients with a do-not-resuscitate (DNR) order. Methods: We retrospectively analyzed medical records of patients who died after agreeing to a DNR order in 2016 at a university hospital. Characteristics including cause of death, intensity of EoL care, and other factors were reviewed and statistically analyzed. Results: Of total 375 patients, 170 patients (45.3%) died with malignancies, and 205 patients (54.6%) with other causes involving the central nervous system (19.2%), pulmonary (14.7%), cardiologic (6.7%) and infectious (6.4%) conditions. Both the cancer and non-cancer patient groups showed a short duration from DNR to death (median 3 days vs 2 days, P=0.629). An intensive care group comprising patients who received one or more intensive treatments such as ventilator (n=205) showed a higher number of non-cancer patients and a shorter duration from DNR to death than a group that withheld treatment before DNR (P<0.05). Conclusion: EoL decisions were made very late by both cancer and non-cancer patients. About half of the patients did not have cancer, and two-thirds of them decided DNR during intensive treatment. To make a good EoL decision, a shared decision making with patients should be done at an earlier stage.

The aim of this study was to test the validity of the hypothesis that the karyotypes of four species of Lepilemuridae were formed spontaneously from their ancestral hybrid karyotype. Hypothetical ancestral haploid Karyotype of Lepilemuridae is composed of 18 autosomes and X chromosomes. Lepilemur mustelinus karyotype has four tandem fused chromosomes and one Robertsonian translocated chromosome pairs. Lepilemur septentrionalis septentrionalis karyotype has only two pairs of translocated chromosomes. We reconstruct and suggest ancestral karyotype of LMU(ancLMU) and LSS(ancLSS), from which all four studied species were derived. Hybrids of ancLMU and ancLSS were formed and produce differently fused equilibrated gametes via circular form arrangement during gametogenesis. Five unit of trivalent homologous chromosome pairs were engaged in a circular form to give new gamete corresponding to the karyotype of L. dorsalis, orientation of one unit of trivalent was inversed in the circle to gave new gamete corresponding to the karyotype of L. leucopus. Seven homologous chromosome pairs were engaged in circular form to give haploid karyotype of Lepilemur ruficaudatus. Only one homologous chromosome pair is dissociated and the other chromosome pairs rearranged in the circle to form haploid karyotype of Lepilemur edwardsi. The new gametes could be produced from these circular forms. When the new gamete fertilized with the same type of gamete, The new homozygote is produced as existing L. dorsalis, L. leucopus, L. edwardsi and L. ruficaudatus. These results support the theory that new species could be formed in hybrid population through activated chromosome fusion, chromosome rearrangement in circular from at zygotene stage and production of equilibrated gametes to form homozygote new species.

This research aims to provide basic materials for assisting DNR patient cares by understanding ICU nurses' awareness and ethical attitude regarding DNR. A total of 154 results were analyzed which were collected from Aug. 1st to Sep. 5th in 2014 by surveying nurses working in ICU (from 1 advanced general hospital in G metropolitan city and other general hospitals of more than 700 beds in Cheolla provinces). (1) For the decision attitudes of DNR, there were both consent and objection. Consent for the patient's opinion of rejecting further treatment and life extension despite of bad prognosis. And objection for no conducting DNR in the case of the patient's wish, treatment requested by the guardian, and CPR for the patient who has no chance. (2) Objection for artificial respirator and other treatment requested by the patient's family and the entrance of guardians into ICU. Consent for the passive use of artificial respirator by the doctor and the decrease of basic care to stabilize patients physically and mentally. No specific opinion for treatment not following aseptic techniques. Objection for frequent reports to primary care physician requested by the family. (3) Acknowledging less interest by the doctor, while supporting the health care team in the case of the guardian's complaint, objection for the DNR decision mede by the primary care physician. Objection for the DNR decision by the guideline. Objection or neutrality for straightforward explanation to the patient of bad prognosis. Objection for straightforward explanation of the patient's status (even near to death) to the patient him/herself or the guardian. In conclusion, the subject of DNR is the patient and the patient's opinion should be fully reflected. The conflict arising from the scope of medical practice and decision processes should be minimized. The standard and guideline for DNR decision is required for the ethical decision making for the patient along with agreements based on full explanations.

This study set out to investigate the effects of the same amount of resting(30 minutes) after $VO_2max$ 20%, 40%, and 60% exercise on the variation of cortisol and catecholamine, serum stress hormones. The research efforts led to the following conclusions: First, there were no significant differences in serum cortisol concentration between the $VO_2max$ 20% group and the $VO_2max$ 40% group, but there were some significant differences in the significance level of p=.002 in the $VO_2max$ 60% group. Second, there were no significant differences in serum catecholamine concentration between the $VO_2max$ 20% group and the $VO_2max$ 40% group, but there were some significant differences in the significance level of p=.001 in the $VO_2max$ 60% group. Third, no significant differences were found in the changing rates of serum cortisol concentration between right after exercise and during break among different levels of exercise intensity according to measuring time. Fourth, there were significant differences in the changing rates of serum catecholamine concentration in the significance level of p=.000 right after exercise and in the significance level of p=.034 during break In short, there were significant differences only in the $VO_2max$ 60% group according to exercise intensity when the different groups took the same amount of break after exercise. The $VO_2max$ 60% group was also the only group that showed significant differences in the changing rates of cortisol and catecholamine. In conclusion, taking a break after exercise can generate huge effects only when the exercise intensity level is moderate or higher. That is, taking a break will have no significant effects when the exercise intensity level is lower than moderate.
The purpose of this study was to perform quantitative comparisons of water permeable zones in both the adhesive and the hybrid layer before and after thermo cycling in order to assess the integrity of the bonding interface. Twenty eight flat dentin surfaces were bonded with a light-cured composite resin using one of four commercial adhesives [OptiBond FL (OP), AdheSE (AD), Clearfil SE Bond (CL). and Xeno III (XE)]. These were sectioned into halves and subsequently cut to yield 2-mm thick specimens; one specimen for control and the other subjected to thermocycling for 10,000 cycles. After specimens were immersed in ammoniacal silver nitrate for 24 h and exposed to a photo developing solution for 8 h, the bonded interface was analyzed by scanning electron microscopy (SEM) and wavelength dispersive spectrometry (WDS) at five locations per specimen. Immediately after bonding. the adhesive layer of OP showed the lowest silver uptake, followed by CL, AD. and XE in ascending order (p < 0.0001); the hybrid layer of CL had the lowest silver content among the groups (p = 0.0039). After thermocycling, none of the adhesives manifested a significant increase of silver in either the adhesive or the hybrid layer. SEM demonstrated the characteristic silver penetrated patterns within the interface. It was observed that integrity of bonding was well maintained in OP and CL throughout the thermocycling process. Adhesive-tooth interfaces are vulnerable to hydrolytic degradation and its permeability varies in different adhesive systems, which may be clinically related to the restoration longevity.
