2006년부터 5년 계획으로 시작한 제3차 전국자연환경조사를 비롯한 우리나라 자연 환경조사의 실태와 일본, 독일, 미국, 영국의 자연환경조사체계를 비교 검토하였다. 국내 여건을 토대로 선진 외국과 우리나라 조사체계를 비교 검토한 결과, 생물종 중심의 자연환경조사에서 벗어나 서식지, 생태계 및 생태권역에 대한 조사를 실시하고, 나아가 위성영상이나 항공사진을 이용하여 토지자원의 공간분포를 주기적으로 파악하여야 할 것이다. 특히 위성영상은 생물종, 서식지, 생태계 조사를 위한 기초 자료로 활용하여야 한다. 조사내용 확대 및 다양한 정보수집을 위해 다방면의 전문인력을 확보하고, 지역주민의 자연환경 보전의식을 고취시키기 위해 자원봉사자의 참여를 유도해야 할 것이다. 전국에 걸친 생물종 및 생태계 조사, 데이터베이스 구축은 물론 자료의 분석 가공을 통해 자연환경정책 수립이나 생물다양성 국제협약에 대처하기 위해서는 독립된 전문조사기관의 설립이 필요하다. 전문조사기관의 설립을 통해서 물리적인 서식환경을 포함한 다양한 분야의 자연환경조사를 체계적으로 수행하고 생물다양성에 대한 종합적인 현황파악과 변화예측을 통해 보다 신속 정확한 자연환경 정보를 생성할 수 있을 것이다.

Purpose: The Korean Gastric Cancer Association (KGCA) has been conducting nationwide surveys on patients with surgically treated gastric cancer, every 5 years, since 1995. This study details the results of the survey conducted in 2019. Materials and Methods: This survey was conducted from March to December 2020 using a standardized case report form, which was sent to every member of the KGCA via e-mail. We collected data on 54 items, including patient demographics, tumor characteristics, surgical procedures, and surgical outcomes. We compared the results of the 2019 survey with previous surveys. Results: Data of 14,076 cases were collected from 68 institutions. The mean patient age was 62.9 years and the proportion of patients who were aged ≥71 years increased from 9.1% in 1995 to 28.8% in 2019. The proportion of upper-third tumors steadily increased from 11.2% in 1995 to 20.9% in 2019 and that of early gastric cancer increased from 57.7% in 2009 to 63.6% in 2019. Regarding operative procedures, a total laparoscopic approach was used in more than half of the cases (55.1%) in 2019. The most common anastomotic method was the Billroth II procedure (45.0%) after distal gastrectomy and double tract reconstruction (81.2%) after proximal gastrectomy in 2019. The postoperative mortality rate was 1.0%, and the overall postoperative complication rate was 14.5%. Conclusions: The results of the 2019 nationwide survey demonstrate the current status of gastric cancer treatment in Korea. This information will provide a basis for gastric cancer research in the future.

BACKGROUND/OBJECTIVES: The prevalence of malnutrition among hospitalized children ranges between 12% and 24%. Although the consequences of hospital malnutrition are enormous, it is often unrecognized and untreated. The aim of this study was to identify the current status of in-hospital nutrition support for children in South Korea by carrying out a nationwide hospital-based survey. SUBJECTS/METHODS: Out of 345 general and tertiary hospitals in South Korea, a total of 53 institutes with pediatric gastroenterologists and more than 10 pediatric inpatients were selected. A questionnaire was developed by the nutrition committee of the Korean Society of Pediatric Gastroenterology, Hepatology and Nutrition. The questionnaires were sent to pediatric gastroenterologists in each hospital. Survey was performed by e-mails. RESULTS: Forty hospitals (75.5%) responded to the survey; 23 of them were tertiary hospitals, and 17 of them were general hospitals. Only 21 hospitals (52.5%) had all the required nutritional support personnel (including pediatrician, nutritionist, pharmacist, and nurse) assigned to pediatric patients. Routine nutritional screening was performed in 22 (55.0%) hospitals on admission, which was lower than that in adult patients (65.8%). Nutritional screening tools varied among hospitals; 33 of 40 (82.5%) hospitals used their own screening tools. The most frequently used nutritional assessment parameters were weight, height, hemoglobin, and serum albumin levels. In our nationwide hospital-based survey, the most frequently reported main barriers of nutritional support in hospitals were lack of manpower and excessive workload, followed by insufficient knowledge and experience. CONCLUSIONS: Although this nationwide hospital-based survey targeted general and tertiary hospitals with pediatric gastroenterologists, manpower and medical resources for nutritional support were still insufficient for hospitalized children, and nutritional screening was not routinely performed in many hospitals. More attention to hospital malnutrition and additional national policies for nutritional support in hospitals are required to ensure appropriate nutritional management of hospitalized pediatric patients.

This nationwide survey was conducted to evaluate the current status of clinical practice for gastric cancer patients in Korea. The Information Committee of the Korean Gastric Cancer Association (KGCA) sent questionnaires containing 45 items about the preoperative diagnosis, medical and surgical treatment, and postoperative follow-up for gastric cancer patients to all 298 KGCA members in 108 institutes. Response rates were $32.6\%$ (97/298) for individuals and $59.3\%$ (64/108) for institutes. Most university hospitals responded (response rate of university hospitals: $71.6\%$, 48/67). The preoperative staging work up was performed primarily by abdominal CT, followed by bone scans, abdominal ultrasound, endoscopic ultrasound, and so on. Gastric cancer patients with stages II, III, and IV usually received adjuvant chemotherapy after a curative operation. About half of the surgeons regarded 2 cm as a safe resection margin in early gastric cancer and 5 cm in advanced gastric cancer. More than half of surgeons usually performed a D2 lymph node dissection in early gastric cancer and D2+$\alpha$ lymph node dissection in advanced gastric cancer. About $20\%$ of surgeons performed less invasive surgery and/or function-preserving surgery, such as a pylorus-preserving gastrectomy, a laparoscopic wedge resection, or a laparoscopy-assisted distal gastrectomy.

National surveys on the prevalence of intestinal parasitic infections have been carried out every 5-7 years since 1971 in the Republic of Korea in order to establish control measures. The present nationwide survey was conducted from June to December 2004. The 10% population sampling data of Population and Housing Census by the Korean government in 2000 was used as the survey population. One sample was selected randomly from each of the 22,858 registered subjects, and a total of 20,541 people were ultimately included in this survey. Fecal examinations were performed by the cellophane thick smear and saturated brine flotation techniques. Pinworm infection was examined by cello-tape anal swab method. This survey also included a questionnaire study for a socioeconomic analysis. The total helminth egg positive rate was 3.7%, and the estimated total positive number among nationwide people was 1,780,000. The rates in urban and rural areas were 3.1% and 6.8%, respectively. As the total egg positive rate in the 6th survey in 1997 was 2.4%, the present survey showed that there was a considerable degree of increase in the prevalence rate of intestinal parasitic infections over the 7-year period following the 6th survey. The largest increases occurred in the egg positive rates of Clonorchis sinensis and heterophyids including Metagonimus yokogawai.

Purpose: The Korean Gastric Cancer Association (KGCA) has conducted nationwide surveys every 5 years, targeting patients who received surgical treatment for gastric cancer. We report the results of the 2014 nationwide survey and compare them to those of the 1995, 1999, 2004, and 2009 surveys. Materials and Methods: From March 2015 to January 2016, a standardized case report form was sent to every member of the KGCA via e-mail. The survey consisted of 29 questions, regarding patient demographics as well as tumor-, and surgery-related factors. The completed data forms were analyzed by the KGCA information committee. Results: Data on 15,613 patients were collected from 69 institutions. The mean age was $60.9{\pm}12.1$ years, and the proportion of patients more than 70 years of age increased from 9.1% in 1995 to 25.3% in 2014. Proximal cancer incidence steadily increased from 11.2% in 1995 to 16.0% in 2014. Early gastric cancer incidence consistently increased and accounted for 61.0% of all cases in 2014. The surgical approach was diversified in 2014, and 7,818 cases (50.1%) were treated with a minimally invasive approach. The most common anastomosis was Billroth I (50.2%) after distal gastrectomy, and the proportion of Roux-en-Y anastomoses performed increased to 8.6%. Conclusions: The results of this survey are expected to be important data for future studies and to be useful for generating a national cancer control program.

The Ministry of Environment have started the 'National Ecosystem Survey' since 1986. It has been carried out nationwide every ten years as the largest survey project in Korea. The second one and the third one produced the GIS-based inventory of species. Three survey methods were different from each other. There were few studies for species distribution using national survey data in Korea. The purposes of this study are to test species distribution models for finding the most suitable modeling methods for the National Ecosystem Survey data and to investigate the modeling results according to survey methods and taxonominal group. Occurrence data of nine species were extracted from the National Ecosystem Survey by taxonomical group (plant, mammal, and bird). Plants are Korean winter hazel (Corylopsis coreana), Iris odaesanensis (Iris odaesanensis), and Berchemia (Berchemia berchemiaefolia). Mammals are Korean Goral (Nemorhaedus goral), Marten (Martes flavigula koreana), and Leopard cat (Felis bengalensis). Birds are Black Woodpecker (Dryocopus martius), Eagle Owl (Bubo Bubo), and Common Buzzard (Buteo buteo). Environmental variables consisted of climate, topography, soil and vegetation structure. Two modeling methods (GAM, Maxent) were tested across nine species, and predictive species maps of target species were produced. The results of this study were as follows. Firstly, Maxent showed similar 5 cross-validated AUC with GAM. Maxent is more useful model to develop than GAM because National Ecosystem Survey data has presence-only data. Therefore, Maxent is more useful species distribution model for National Ecosystem Survey data. Secondly, the modeling results between the second and third survey methods showed sometimes different because of each different surveying methods. Therefore, we need to combine two data for producing a reasonable result. Lastly, modeling result showed different predicted distribution pattern by taxonominal group. These results should be considered if we want to develop a species distribution model using the National Ecosystem Survey and apply it to a nationwide biodiversity research.
