Three bamboo stands(Phyllostachys pubescens(Mazel) Ohwi, P. bambusoides Sieb. et Zucc, P. nigra var. henonis Stapf ex. Rendle) were selected to determine suitable biomass equations and productivity of Gajwa and Wola National Experimental Forests, Jinju, Southern Korea. Different independent variables such as diameter at breast height(DBH) or the combination of DBH and height(H) were used to develop biomass equations(Allometric model : logY = a + blog DBH; Linear-quadratic model : Y=aDBH + bDBH2; Linear model with DBH and height : Y=a + bDBH2·H) for each bamboo component from two age-sequence(current-year, > 1-year-old) of three bamboo stands. Based on statistical indicators, the most suitable equation model to estimate biomass from bamboo stands was a linear-quadratic model. Aboveground biomass of three bamboo stands estimated by the model was 48.864 Mg ha-1 for the P. pubescens, followed by 36.632 Mg ha-1 for the P. bambusoides, and 36.504 Mg ha-1 for the P. nigra var. henonis stands, respectively. The highest biomass in the P. pubescens stand was attributed to the morphological growth characteristics such as DBH and height. Belowground biomass was also highest for P. pubescens(53.35 Mg ha-1), followed by the P. bambusoides(36.73 Mg ha-1) and the P. nigra var. henonis(29.75 Mg ha-1) stands. The results indicate that the morphological growth characteristics such as DBH and height among bamboo species were the most important factor to determine bamboo biomass productivity at a local level.

배추좀나방과 담배거세미나방 유충에 대한 30종 한방 식물체 메탄올 조추출몰의 살충활성 및 섭식 저해활성을 잎침지법을 이용하여 5,000ppm으로 검정하였다. 황련의 추출물은배추좀나방에 대해 살충작용을 보였다. 길경, 사삼, 세신, 오배자 및 자초의 추출물은 배추좀나방 유충에 대해, 목통 및 속새의 추출물은 담배거세미나방 유충에 대한 강한 섭식저해활성을 보였으나, 오배자와 황련의 추출물은 이들 나비목 유충 모두에 강한 섭식저해활성을 나타내었다.

Korea represents high suicide rate by poisoning. Especially, since a lot of people died by high concentrated paraquat which has extremely high fatality rate, paraquat sales were prohibited in 2012. We investigated to find out how the prohibition of sales affected occurrence of pesticide poisoned patients and what kinds of influences did it have for severity and death rate. By targeting patients who visited emergency room by pesticide poisoning from 2010 to 2014, we researched insecticides poisoned patients and herbicidal poisoned patients grouped into 9 categories. Before and after 2012, We compared A term (2010, 2011) and B term (2013, 2014)’s pesticide occurrence, especially distribution of herbicide occurrence and compared hospitalization rate, hospitalization period, length of stay in ICU (Intensive Care Unit), severity, and death rate. The number of insecticide patients was 219 (37.4%) and the number of herbicide patients was 367 (62.6%) who visited emergency room in five years and the rate was similar every year. In case of paraquat, there was 70.5% decrease by 105 people for A term and 31 people for B term and increase of double for glyphosate, glufosinate, and other herbicides. The death rate was decreased but hospitalization was increased. There weren’t any difference of rate in ICU admission, intubation and ventilator therapy. By prohibition of using paraquat, the death rate by pesticide poisoning was decreased. However, patients who poisoned by other herbicides were increased, so hospitalization rate increased and there weren’t any difference at patient’s severity rates.

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.

The purpose of this research is to compare between past and present resuscitation outcome of cardiac arrest patients in one emergency department. A clinical analysis of 429 cases of CPR performed in one emergency department from April 2013 to March 2015 was conducted. Then we compared this with previous paper that were written in same emergency department in 2004. During the period, 429 patients received resuscitations. Between the two studies, all patients under CPR were increased 2.27 times (94.33 pts/years to 214.5 pts/years). As the cause of cardiac arrest, traumatic cardiac arrest increased to 30.1% form 24.1%. Cardiogenic cardiac arrest showed highest survival rate in two studies, and the ratio was increased from 6.8% to 15.2%. VF/VT showed highest survival rate in two studies, and the ratio was increased from 8.8% to 20.7%. In this study, At least who once became ROSC patients was 260 people (60.6%), permanent surviving patient was 34 people (7.93 %), patients with CPC score 1-2 was 26 people (6.06%). The survival rate of patients with cardiac arrest has increased compared to the past. But in-hospital cardiac arrest survival rate is still low so it is necessary to increase the recovery rate of cardiogenic arrest survival rate to increase the permanent survival rate and good prognosis patients.

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.
