Background/Aims: Westernization in many Asian countries have changed lifestyles and diets, so once rare diseases have now become prevalent. The aim of this study is to investigate the changing pattern of digestive and liver disease in Korea, from 1990 to 2006. Methods: We extracted data specific gastrointestina (GI) disease based on the International Classification of Diseases code from the in-patients records at the Kangnam St. Mary`s Hospital in 1990, 1996 and 2006. This hospital is a tertiary-care hospital in Seoul, Korea, which has a capacity of 800 beds. Results: The admission rate for GI disease increased between 1990 and 2006. Overall in-patients were 1,623 persons in 1990, 2,368 persons in 1996 and 4,166 persons in 2006. The mean age of in-patients increased as time went by. A stomach cancer was the most common diagnosis during all periods, but its prevalence has decreased. Colon cancer ranked the 7th in 1990, but markedly increased and now ranks the second. The third was a hepatocellular carcinoma. The bile duct and gallbladder cancer, pancreas and esophageal cancer ranking followed with little interval change. In cases of cancer patients, a regular admission dramatically increased for chemotherapy. The number of patients admitted with pre-malignant neoplasm of stomach and colon increased remarkably with the development of endoscopy. The liver transplant, inflammatory bowel discase, and reflux esophagitis emerged form mid-1990s with greater frequencies, yet much below the levels found in the West. The admission rate for peptic ulcer, especially ulcer bleeding remained relatively stable, despite a decreased rate for ulcer perforation. Liver cirrhosis, hepatitis, cholelithiasis with cholecystitis-cholangitis, appendicitis, hemorrhoid and gastritis all decreased. Conclusions: The stomach cancer is the leading cause of admission, despite a recent decline. Colon cancer showed a marked rise. The liver transplant, inflammatory bowel disease and reflux esophagitis were new diagnosis with an increased tendency.

최근 4차 산업 혁명 및 코로나19로 인해 비대면 서비스 시장의 수요가 증가하고 있으며, 전 세계적으로 로봇을 이용한 다양한 서비스들이 개발되고 있는 추세이다. 본 논문에서는 사람 대신 로봇이 테이블 위에 놓인 물체들을 적절한 수거함들로 옮겨 테이블을 정리해주는 지능형 로봇 서비스를 구현함으로 목표로 한다. 효과적인 목표 서비스 개발을 위해, 본 연구에서는 딥러닝 기반의 심층 물체 자세 추정기를 이용해 물체들의 실시간 위치를 파악하고, 시멘틱 웹 기반의 지능형 로봇 체계를 활용하여 작업 환경에서 동적 상황 정보를 추론해낸다. Recently, due to the 4th Industrial Revolution and COVID-19, demand in the non-face-to-face service market has been increasing and there is a trend to develop various useful robot services around the world. In this paper, we aim to develop an intelligent robot service that the robot cleanups a table by picking and placing objects placed on the table into proper bins instead of human users. In order to develop the target service effectively, we use a deep learning-based object pose estimator to find out real-time pose of individual objects, and make use of a robot intelligence framework based on semantic web technology to infer dynamic context from the task environment.

Song, Jung Sub,Jang, Jie Young,Shinn, Kyung Sub,Lee, Sun Hee,Choi, Ihl Bhong,Kim, In Ah,Kang, Ki Mun,Park, Jae Gil,Kuak, Mun Sub THE CATHOLIC UNIVERSITY OF KOREA 1997 Bulletin of The Catholic Research Institutes of Me Vol.25 No.-

This study was tried to evaluate the potential benefits of concurrent chemoradiation therapy(low dose daily cisplatin combined with split course radiation therapy) compared with conventional radiation therapy alone in stage Ⅲ non-small cell lung cancer. The end points of analyses were response rate, overall survival, survival without locoregional failure, survival without distant metastasis, prognostic factors affecting survival and treatment related toxicities. Between April 1992 and March 1994, 32 patients who had stage Ⅲ non-small cell lung cancer were treated with concurrent chemoradiation therapy. Radiation therapy for 2 weeks (300 cGy given 10 times up to 3000 cGy) followed by a 3 weeks rest period and then radiation therapy for 2 more weeks(250 cGy given 10 times up to 2500 cGy) was combined with 6㎎/M^2 of cisplatin. Follow-up period ranged from 13 months to 48 months with median of 24 months. Historical control group consisted of 32 patients who had stage Ⅲ non-small cell lung cancer were received conventionally fractionated(daily 170-200 cGy) radiation therapy alone. Total radiation dose ranged from 5580 cGy to 7000 cGy with median of 5940 cGy. Follow-up period ranged from 36 months to 105 months with median of 62 months. Complete reponse rate was higher in chemoradiation therapy(CRT) group than radiation thernpy(RT) group(18.8% vs. 6.3%). CRT group showed lower in-field failure rate compared with RT group(25% vs. 47%). The overall survival rate and no significant differences in between CRT group and RT group(17.5% vs. 9.4% at 2 years). The survival without locoregional failure (16.5% vs. 5.3% at 2 years) and survival without distant metastasis(17% vs. 4.6% at 3 years) also had no significant differences. In subgroup analyses for patients with good performance status(Karnofsky performance scale≥80), CRT group showed significantly higher overall survival rate compared with RT group(62.5% vs. 15.6% at 2 years). The prognostic factors affecting survival rate were performance status and pathologic subtype(sqamous cell cancer vs. nonsquamous cell cancer) in CRT group. In RT alone group, performance status and stage (Ⅲa vs. Ⅲb) were identified as a prognostic factors. RTOG/EORTC grade 2-3 nausea and vomiting(22% vs. 6%) and bone marrow toxicities(25% vs. 15.6%) were significantly higher in CRT group compared with RT alone group. The incidence of RTOG/EORTC grade 3-4 pulmonary toxicity had no significant differences in between CRT group and RT group(16% vs. 6%). The incidence of WHO grade 3-4 pulmonary fibrosis also had no significant differences in both group(38% vs. 25%). In analyses for relationship of field size and pulmonary toxicity, the patients who treated with field size beyond 200㎠ had significantly higher rates of pulmonary toxicities. Conclusions: The CRT group showed significantly higher local control rate than RT group. There were no significant differences of survival rate in between two groups. The subgroup of patients who had good performance status showed higher overall survival rate in CRT group than RT group. In spite of higher incidence of acute toxicities with concurrent chemoradiation therapy, the survival gain in subgroup of patients with good performance status were encouraging. CRT group showed higher rate of early death within 1 year, higher 2 year survival rate compared with RT group. Therefore, to evaluate the accurate effect on survival of con- current chemoradiation therapy, systematic follow-up for long termsurvivors are needed.

Ⅰ. 연구개요 1. 연구의 배경 및 목적 □ 최근 한국사회의 노인돌봄과 관련한 대표적인 변화는 ‘남성(남편, 아들 등)’이 독립적으로 일상생활을 영위하는데 제한이 있는 노인에게 돌봄을 제공하는 주된 역할을 수행하는 비율이 꾸준히 증가하고 있다는 점임. - 그러나, 기존 국내 노인돌봄 연구는 ‘여성’ 돌봄자의 돌봄 경험, 부양부담 및 부담경감 방안에 초점을 두고 수행되었으며, ‘돌봄의 주체’로서의 남성과 남성의 돌봄자로의 역할 전환(transition) 과정에 초점을 둔 연구는 제한적으로 수행됨. - 국외에서는 증가하는 남성돌봄자의 이슈를 탐색하기 위해 돌봄 수행방식 및 주돌봄자가 인지하는 노인돌봄 부담에 있어서의 성별차이(Akpinar et al., 2011; Montgomery, 1992; Pinquart & Sorensen, 2006; Stoller, 1992), 남성의 노인돌봄 경험(히라야마 료, 2015; Pretorius et al., 2009; Ribeiro et al., 2007; Sanders & Power, 2009) 및 남성성이 남성돌봄자들의 노인돌봄 경험에 미치는 영향(Baker et al., 2010; Russell, 2007) 등에 관한 다양한 연구가 진행된 바 있으며 국내에서도 노인을 돌보는 남성돌봄자에 대한 심층적 연구가 필요하다고 제안된 바 있으나(이순미·김혜경, 2009; 최희경, 2012a) 남성들의 돌봄 경험을 면밀히 탐색한 연구는 제한적으로 수행되었음. - 이에 본 연구는 남성들의 노인돌봄 경험을 남성의 관점에서 분석하고, 돌봄을 둘러싼 젠더정체성 및 가족관계 변화양상을 포착하여 선제적인 가족정책을 수립하는데 필요한 기초자료를 제공하고자 함. □ 본 연구의 목적은 남성(남편, 아들 등)에 의한 노인돌봄 현황 및 남성의 돌봄자로의 역할 전환 과정을 살펴보고, 이들의 정책지원 욕구를 파악하여 제도보완 및 남성 가족돌봄자를 위한 정책개발의 시사점을 제공하는 것임. 2. 연구의 주요 내용 □ 본 연구의 주요 연구문제는 다음과 같음. - 첫째, 배우자 또는 (조)부모를 돌보는 남성의 가족돌봄 현황(예: 돌봄기간, 시간, 돌봄 이유, 돌봄자 및 요보호노인의 건강상태, 사회적 지지망 등) 및 돌봄부담(burden)은 어떠한가? - 둘째, 남성이 배우자 또는 (조)부모를 돌보게 되면서 경험하게 된 변화(예: 관계적 측면, 돌봄의 의미 등)는 무엇인가? - 셋째, 배우자 또는 (조)부모를 돌보는 남성의 삶의 질은 어떠한가? - 넷째, 배우자 또는 (조)부모를 돌보는 남성의 가족돌봄 지원 정책(예: 노인장기요양보험제도 등)에 관한 인지도 및 이용 경험, 정책지원 욕구는 어떠한가? 3. 연구방법 □ 문헌 연구 - 본 연구에서는 남성의 노인 돌봄에 관한 국내외 선행연구 및 우리나라와 일본의 가족돌봄자 지원제도에 관한 자료를 검토하였음. □ 2차 통계자료 분석 - 2014년도 노인실태조사 (정경희 외, 2014)를 활용하여 요보호노인의 일상생활을 수행하는데 도움을 주는 사람, 가족원 중 가장 도움을 많이 준 사람 및 주당 돌봄시간 등을 분석하였음. □ 설문조사 및 분석 - 조사대상은 일상생활을 스스로 영위할 수 없는 55세 이상 노인을 조사시점에서 3개월 이상, 주당 15시간 이상 돌보고 있는 가족원 중 남성(남편, 아들 등) (N=247)으로 설정하였고, 구조화된 설문지를 이용하여 1:1 면접조사를 수행하였음. 조사표는 1) 가족 및 돌봄대상자 특성, 2) 돌봄현황, 3) 사회적 지지, 4) 응답자의 건강 및 경제활동, 5) 가치관 및 삶에 대한 태도, 6) 정책지원 욕구로 구성하였으며, 수집된 자료를 분석하여 남성의 돌봄 현황 및 돌봄 부담, 역할전환 과정, 돌봄지원 정책 및 서비스 이용 경험과 정책지원 욕구 등을 파악하였음. □ 심층면접 조사 및 분석 - 남성돌봄자의 돌봄 경험을 보다 입체적으로 파악하기 위해 일상생활을 독립적으로 영위할 수 없는 배우자 또는 부모를 조사시점에서 3개월 이상, 1주 평균 15시간 이상 돌보는 남성(17명)을 대상으로 1:1 면접을 수행하였음. 심층면접에서는 돌봄 상황 및 관계적 특성이 돌봄에 미치는 영향, 돌봄 경험의 의미, 돌봄지원 정책 및 서비스 이용 경험과 정책지원 욕구 등에 대해 살펴보았음. □ 전문가 자문회의 - 관련 분야 전문가를 대상으로 전문가 자문회의를 개최하여 연구설계 및 방법, 정책대안에 대한 관련 부처 및 전문가 자문의견을 수렴하였음. 4. 연구의 기대효과 및 한계점 □ 본 연구는 그동안 제한적으로 수행된 연구인 ‘남성’ 가족돌봄자의 노인돌봄 경험을 탐색하고, 학술적·정책적 시사점을 도출하였다는 점에서 연구의 의의를 찾을 수 있음. - 그러나, 노인을 돌보는 남성 가족돌봄자 모집단을 추정할 수 있는 자료의 부재로 임의할당추출에 의한 설문조사를 시행하여 결과를 일반화하는데 한계가 있음. - 남성돌봄자만을 대상으로 조사를 시행하여 여성돌봄자와의 돌봄 경험 및 부양부담의 차이를 직접적으로 비교하지 못 The number of male family caregivers in Korea, especially those providing spousal caregiving in old age, has been steadily increasing. However, since women have long predominated in the family caregiving role, few studies have explored the experience of caregiving by males in terms of the breadth and depth of care work and its meaning. The purpose of this study was to explore the caregiving experience of husbands and sons providing care to a spouse or parent(s) aged 55 and older who showed limitations in activities of daily living (ADL) or instrumental activities of daily living (IADL) for a period of at least six months. Both quantitative and qualitative methods were utilized for this study. Survey data were collected from a purposive sample of 247 male caregivers who served as the primary care providers for a dependent spouse or parent(s). Descriptive statistics and multivariate models were obtained using SPSS Statistics. In addition, semi-structured in-depth interviews with 17 male caregivers were conducted. For the qualitative analysis, a comprehensive content review of all data, including line-by-line analysis, was conducted. Informed consent was obtained from the participants. Some of the major findings are as follows: First of all, approximately one-fourth of respondents identified personal bonds as being their motivation for taking care of a dependent spouse or parent(s). The average caregiving period was around 47.7 months, and respondents spent approximately 34.1 hours per week on average on caregiving. Secondly, the majority of respondents in our sample reported that they experienced caregiving to be burdensome to some degree, especially in the areas of assistance with bathing (52.9%), voiding (49.5%), household management (44.6%), and meal preparation (50.6%). A significant number of respondents reported that one of the most difficult aspects of caregiving was balancing a personal life with the caregiving role, and most respondents stated that the initial phase of caregiving was the most difficult as they made the transition to the new role as caregiver and restructured their life. In addition, spousal caregivers generally experienced a higher level of caregiving burden compared to son caregivers since they are more likely to be older, unhealthier, and have fewer resources. However, a majority of male caregivers also found caregiving to be a very rewarding experience in that they felt useful (72.9%) by providing care to a dependent family member or they had grown closer to their dependent spouse or parent(s) as a result of the caring (54.7%). Thirdly, about 65% of respondents reported that they had secondary caregivers available to support them regularly in their caregiving. This finding supports previous research in which male caregivers were found to be more likely to have access to additional informal caregivers than were female caregivers. Fourth, although a significant number of respondents in our sample reported that they were aware of long-term care insurance (LTCI) benefits, the number of respondents who were receiving LTCI benefits was relatively smaller. Likewise, while approximately 80% of respondents reported being satisfied with the overall services available, the in-depth interview participants suggested that service adequacy, especially in-home care service, was insufficient for assisting family caregivers with balancing work life with the caregiving role. They also suggested that overall service quality should be improved to enhance quality of life among both older adults and family caregivers. However, in the regression analysis, use of LTCI benefits was not a predictor of male caregivers’ burdens.

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

순산소 연소기술은 화력발전에 적용 가능한 유망한 온실가스 감축 기술로 평가되고 있다. 본 연구는 환경적 관점에서 순환유동층을 활용한 순산소 연소조건에 로 내 탈황 및 탈질법을 적용하여 NO 및 SO₂의 거동을 살펴보는 한편, SO₃, NH₃, 그리고 N2O의 발생 경향도 관측하였다. 이를 위해, 연소로 내 석회석 및 요소수를 투입하였다. 로 내 탈황법은 연소가스 내 SO₂ 농도를 ~403에서 ~41 ppm까지 저감하였다. 또한 SO₃ 형성의 주원료인 SO₂가 저감되면서 연소가스 내 SO₃ 농도도 ~3.9에서~1.4 ppm까지 감소되었다. 그러나 석회석 내 CaCO₃가 NO의 발생을 촉진하는 현상도 관측되었다. 연소가스 내 NO 농도는로 내 탈질법을 적용하여 ~26 - 34 ppm까지 저감되었다. 요소수 투입량 증가에 따라 연소가스 내 NH₃ 농도가 증가하여 최대~1.8 ppm으로 나타났으며, N₂O의 농도도 ~61에서 ~156 ppm까지 증가하였다. N₂O 발생량 증가 현상은 요소수의 열분해 과정에서 생성된 HNCO가 N₂O로 전환되어 나타난다. 본 연구의 결과를 통해 로 내 연소가스 세정법을 적용할 경우 NOx 및 SOx의 저감뿐만 아니라, 다른 오염물질의 발생에 대한 주의가 필요할 것으로 보인다. Oxy-fuel combustion is considered as a promising greenhouse gas reduction technology in power plant. In this study, the behaviors of NO and SO₂ were investigated under the condition that in-furnace deNOx and deSOx methods are applied in oxy-fuel circulating fluidized bed combustion condition. In addition, the generation trends of SO₃, NH₃ and N2O were observed. For the purpose, limestone and urea solution were directly injected into the circulating fluidized bed combustor. The in-furnace deSOx method using limestone could reduce the SO₂ concentration in exhaust gas from ~403 to ~41 ppm. At the same experimental condition, the SO₃ concentration in exhaust gas was also reduced from ~3.9 to ~1.4 ppm. This trend is mainly due to the reduction of SO₂. The SO₂ is the main source of the formation of SO₃. The negative effect of CaCO₃ in limestone, however, was also appeared that it promotes the NO generation. The NO concentration in exhaust gas reduced to ~26 - 34 ppm by appling selective non-catalytic reduction method using urea solution. The NH₃ concentration in exhaust gas was appeared up to ~1.8 ppm during injection of urea solution. At the same time, the N₂O generation also increased with increase of urea solution injection. It seems that the HNCO generated from pyrolysis of urea converted into N₂O in combustion atmosphere. From the results in this study, the generation of other pollutants should be checked as the in-furnace deNOx and deSOx methods are applied.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

The study aimed to identify leaf sheath through the investigation a characteristic of leaf by planting depth and leaf sheath function through the investigation of effect of leaf sheath removals on growth and flowering in forcing of Lilium cultivars. The number of leaf sheath of 'Jolanda', 'Dream Land', 'Casablanca' were 6, 5, 11 in 0㎝ planting depth and 6, 5, 14 in 6㎝ planting depth. The number of leaf sheath in 'Jolanda' and 'Dream Land' were little different in according to planting depth. The other hand, the number of leaf sheath in 'Casablanca' were increased 3 when it were planted in 6㎝ planting depth. As leaf sheath were removed, plant height and stem root growth were decreased in 'Le Reve' and 'Casablanca'. Whereas the growth of basal root and flower number varied among of Lillium and stem diameter, the days of flowering and flower size were little different.

In this study, the frequencies and types of questions about LIFE areas of the Science Curriculum of elementary school students were investigated through in-depth interviews with twelve 4th and 5th graders. The results of the research can be summarized as follows: (1) In conjectural question, the proportions of 'object exploration question' and 'object verification question' were high in all of the 4th graders and the students of low achievement level. (2) The numbers of causal questions generated by the 4th graders were much higher than those of the 5th graders. (3) The frequencies of the predictive, methodological, applicative questions were very low both in 4th and 5th grade students. (4) The numbers of conjectural questions were more in all students except the low achievement level of 4th graders at not-yet-taken contents than at already-taken ones. (5) The numbers of causal questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (6) The numbers of the predictive, methodological, applicative questions of the 4th graders were more at not-yet-taken contents than at already-taken ones, whereas opposite trend in the 5th graders. (7) The numbers of students' curriculum-related questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (8) As ways for solving or seeking answers about questions, the 4th graders suggested methods of consulting experts or teachers (23.9%), internet searching (21.6%), and books or science-related encyclopedia (20.3%), while the 5th graders suggested the internet searching (36.5%), consulting experts or teachers (24.8%), and books or science-related encyclopedia (17.7%). Based an these results, we suggest several ways for improving the question-posing abilities of the students and adequate use of students' questions in the process of science teaching learning.
