Depending on the living styles, the types of energy consumed by households have changed, and the consumption has increased rapidly. Consequently, those have led to environmental issues, such as exhaustion of energy and the climate changes. As one of solutions to such issues, energy efficiency can be approached. Therefore, in this study, the gas water heater(115S type Rheem products) that made in Germany and obtain hot water using gas as a heat source is selected. a 1.0㎥ water tank with a 6kW electronic heater is installed and a water temperature and pressure is maintain constantly also thermometer is injected. Two of gas meter, one of pressure regulator and three of time measurement devices are installed in a combustion facility and fuelling facility with a magnet valve so it can observe and record combustion reactions. Quantity of hot water that heated by boiler is recorded using a quantity measurement tank, and have been heated by the boiler have been to record and measure the amount and utilized the data acquired through measurement of all factors that are applied to acquire hot water in order to calculate the use rate of final energy. In conclusion, this researcher drew the economic strong points of the hot water generated by gas.Key

Gastrointestinal stromal tumor (GIST) is the most common soft tissue sarcoma of the gastrointestinal tract. Surgery is the primary treatment of choice for patients with localized or potentially resectable GIST, whereas imatinib is the main treatment for patients with advanced, unresectable, or metastatic GIST. Neoadjuvant treatment with imatinib is not routinely recommended unless there is significant justification for reducing the tumor size in order to improve surgical outcome. The authors describe a case of a 48-year-old man who confirmed huge rectal GIST, and received successful neoadjuvant treatment with imatinib for preserving anal sphincter function followed by transanal excision.

The aim of this study is to confirm the importance of a more immediate advanced cardiac life support (ACLS) through a comparative analysis of the results of cardiopulmonary resuscitation (CPR) according to the occurrence place of cardiac arrest in tertiary emergency department. The subjects were 493 patients who had received CPR in Chosun university, Emergency Medical Department, between April 2013 and March 2015. The subjects were categorized into three groups according to the occurrence place of cardiac arrest: pre-hospital, in-emergency room, and in-ward. We conducted a clinical analysis of the results. During the period, 493 cardiac arrest patients underwent CPR, 63 patients (12.8%) were discharged alive and 41 patients (8.3%) got a good score on the cerebral performance category (CPC). Concerned occurrence place of cardiac arrest, 11.3% (16 patients) of the in-emergency room group (total 288 patients) were discharged alive. Also, 9.4% (27 patients) of the In-emergency room group got a good score on the CPC. In the other two-group cases, 7.1% (10 patients) of pre-hospital group (total 141 patients) and 6,2% (4 patients) of in-ward group (total 64 patients) got a good score on the CPC. These results indicate that both the rates of alive discharge and a good CPC score of the in-emergency room group are higher than in out-of-emergency room. This difference might be due to the fact that patients could get the more immediate ACLS by emergency medicine doctors if cardiac arrest occurs in emergency room than other places.

Recently there are increasing numbers of people participating in sports activities. Accordingly, the rate of sports injuries is increasing as well. In this light, this study was conducted to investigate the extent of acute damage and its forms by examining the current state of patients with sports injuries. This research study was conducted between January of 2008 and December of 2010 in Chosun University Hospital through retrospective review of the medical records of patients with sportsrelated injuries. The total number of patients with sports injuries who visited the emergency center was 887. The number of male patients was 726 (81.85%), far more than the number of female patients (18.15%). More than half of the patients, accounting for 419 (47.23%), had injuries on their face; second and common parts, in which injuries occurred, were upper and lower body, accounting for 146 (16.45%) and 193 (21.75%), respectively. The majority of patients did not undergo surgical treatment. Only 113 (12.73%) patients underwent surgical treatment. In addition, more than 80% of them were not hospitalized but 170 of them needed to be hospitalized. Most sports injuries occurred in young male patients. This can interrupt participation in sports activities for a long time and result in lower quality of life. Hence proper preventative measures and scientific treatment methods are needed.

Ionizing radiation is known to cause chromosomal alterations such as inversions and deletions and affects gene expression within the plant genome. To monitor the genome-wide transcriptome changes by ionizing radiation, we used rice Affimetrix GeneChip microarray to identify genes that are up- or down regulated by gamma-ray (200 Gy, 60Co source), cosmic-ray and ion beam (40 Gy, 220 MeV carbon ion). The overall expression patterns between gamma-ray and ion beam were similar but cosmic-ray was regulated differently. Combined results from all 3 radiations identified 27 up-regulated genes and 188 down regulated genes. These results mean the induction of similar mechanism changes in treatments of gamma ray and ion beam. However the different expression in treatment of cosmic-ray might be due to the other environmental conditions. Among the commonly up- or down- regulated genes, we chose highly up- or down- regulated several genes and confirmed its regulation in response to ionizing radiation exposure by RT-PCR analysis. Moreover, we showed that specific co-expression networks of candidate radio marker genes by ARACNE algorithm. Our results present profiles of gene expression related to different ionizing radiation and marker gene to predict sensitivity to ionizing radiation, such as GS (glutelin subunit) and FBX322.

A new six-rowed naked waxy barley variety, ‘Saehanchal’, was developed by the barley breeding team of the National Institute of Crop Science (NICS), R.D.A. This variety was derived from a cross between ‘SB7803G-BC6-B-B-47-2’ and ‘Suwon262’ in 1989. The fi
