This study aims to identify contributing factors to Severity-Adjusted LOS (Length of Stay) variation of patients damaged to neck in order to suggest ways of reducing the LOS at the national level and the medical institution level. 14,096 inpatients with neck injury were selected as the study population from the 2004-2009 Korean National Hospital Discharge in-depth Injury Survey Data. We developed a Severity-Adjusted LOS Model for neck injuries using data-mining methods. This study discovered that operation Y/N, sex, age, admission route, injury mechanism, comorbidities Y/N (spondylosis & intervertebral disc disorders, Spinal cord injury, Skull & facial fractures, Other fractures, sprains and strains etc.) were factors affecting LOS for patients hospitalized with neck injury. According to the results of the impact of the health-insurance type on severity-adjusted LOS, the real LOS was significantly higher than adjusted LOS for patients with the industrial accident compensation insurance or medical aid program. Therefore, in order to manage LOS of inpatients with neck injury, the government should improve the industrial accident compensation insurance review & assessment service and suggest alternatives on medical aid recipients` excessive medical utilization. Also, the hospitals should take account of objective and reliable LOS statistics to effectively manage hospital LOS.

중학교 수학교과에서 웹과 모눈그래퍼를 이용한 ICT활용 수업이 학업 성취와 태도에 미치는 효과
홍성옥 ( Sung Ok Hong ),윤주한 ( Ju Han Yoon ),은광식 ( Kwang Sik Eun ) 충북대학교 과학교육연구소 2005 과학교육연구논총 Vol.21 No.2
본 연구의 목적은 중학교 수학과 이차함수 단원을 중심으로 전통적 수업과 ICT활용 수업간에 학습자들의 학업성취도와 수학교과에 대한 태도에 있어서 차이가 있는가를 탐색해 보는데 그 목적이 있다. 이를 위해 다음과 같은 연구 문제를 선정하였다. 첫째, 중학교 수학과 이차함수 단원에서 ICT활용 수업을 받은 학생들과 전통적인 수업을 받은 학생들의 학업성취도가 문항 유형별로 의미 있는 차이를 보이는가? 둘째, ICT를 활용한 수업이 학생들의 수학에 대한 태도의 변화를 가져오는가? 이 연구는 청주 S중학교 3학년 두 반을 각각 실험반(36명)과 비교반(35명)으로 선정하여 4주간 12차시에 걸쳐 이차함수 단원을 수업하였다. 전통적 수업을 하는 비교반은 교사 중심의 수업을 교과서 위주로 전개하였다. ICT활용 수업을 하는 실험반은 6차시 동안 1인 1PC가 제공되는 컴퓨터실에서 에듀넷이 제공하는 멀티미디어 자료를 교사가 미리 선별하여 학생들에게 안내, 학습하도록 하였고 동시에 모눈 그래프 프로그램으로 학습자가 스스로 학습하는 학습자 주도형 수업을 하였고 나머지 6차시는 멀티비젼이 있는 교실에서 교사 주도형 ICT활용 수업을 하였다. The purpose of this study is to investigate the effects of ICT applied Mathematics and quadratic function class in terms of students□□ achievements and attitudes. The followings are the main results of this study. First, they make a little significant difference between traditional classes and ICT applied classes in the achievements of classwork. But analyzing classification of each question, I confirm that ICT which has dynamic and geometric expression has some positive influence.

Pinus radiata 소나무의 정아내 (頂芽內) Arginine 함량 시기적변화
홍성옥(Sung Ok Hong),지 비 수이트(Geoffrey B . Sweet) 한국산림과학회 1977 한국산림과학회지 Vol.33 No.1
Seasonal changes in free arginine concentration in Pinus radiata buds were studied in four clones from May, 1974 to June, 1975. The buds were from the tips of first order branches which had flowered the previous year, and the significant findings were as follows: (1) In general, arginine concentration in the buds of the four clones showed the highest peaks from December to March, a period spanning the time of flower initiation, and the lowest levels in Angust and September. (2) The timing of individual arginine peaks during the period of flower initiation matched roughly the timing of initiation of several female cone clusters, as determined from Clone 7 which characteristically initiates three cycles of female cones on its leading shoot. (3) The heavy-flowering clones showed higher arginine concentration than ther poorer flowering ones, especially at the time of flower initiation.

지방거주환자의 서울지역 의료기관 이용에 영향을 미치는 요인
홍성옥(Sung-Ok Hong),서원식(Won S. Suh) 한국보건교육건강증진학회 2009 보건교육건강증진학회지 Vol.26 No.4
Objectives: The primary objective of the study is to analyze the utilization patterns of provincial patients discharged from hospitals located in Seoul area. Methods: For the analysis, the study employed the nationwide data on ‘Survey of Injured Patients Discharged from Hospitals’ conducted by KCDC (Korea Centers for Disease Control and Prevention). The statistical methodology used in the measurement model is a logistic regression model. Results: The study has three major findings. First, compared to other disease groups, the discharged on both ‘neoplasm(cancer)’ and ‘congenital malformation, deformity and chromosomal abnormalities’ disease groups are more likely to utilize hospitals in Seoul area. Second, as for ‘neoplasm(cancer)’ disease group, patients with ‘bones and articular cartilage’ areas are more likely to utilize hospitals in Seoul area. Finally, Hospitals with more than 1,000 beds was primary factor in selecting Seoul-based hospitals by the discharged in provincial areas. Conclusion: In sum, the study showed that patients in provincial areas are more likely to utilize hospitals located in Seoul area regardless of the severity of their cases. Local authority, therefore, is required to monitor local hospitals on regular basis, as well as support them to establish specialized medical centers by providing human and physical resources.

Pinus radiata 엽속삽목의 (葉束揷木) 시험관내 발근 (發根)
홍성옥,지 비 수이트 ( Sung Ok Hong,Geoffrey B . Sweet ) 한국산림과학회 1976 한국산림과학회지 Vol.32 No.1
A series of rooting experiments of P. radiata needle fascicles were carried out in test tubes using peat-pumice medium to see a possibility of rooting fascicles in test tubes and, if possible, to find out whether that method can improve the rooting. Typical rooting of clones from ortets aged 3, 7, 11. 18, and over 40, respectively, was 57%, 47%, 18%, 4%, and 2%. The effect of ortet ages upon rooting of fascicle cuttings was significantly exerted in these experiments. In the older ortets these results are not as good as those often obtained in a glasshouse. Hormones tested (indolebutyric acid and abscisic acid) had no significant effect on rooting and neither did a series of fungicides tested. Needle fascicles placed in an 18 hour day at 20˚/10℃ (day/night temperature) rooted signficantly better than those in a 10 hour day at the same temperature regime. The latter in turn rooted better than those set under a 10 hour day at 15˚/5℃. Clonal differences in rooting ability were also distinct in every trial of the present experiments with needle fascicles.
