본 연구는 해방 이후 현대 교육의 이상적 인간상을 살펴보기 위하여 우선 해방 이후에서 90년대에 이르는 시기를 광복 이후 분단까지의 '전환기'와, 경제성장을 통한 현대 국가 발전의 기반이 된 '산업화 시기', 그리고 다양한 계층의 사람들이 정치?경제?사회 참여를 요구하는 '민주화 시기'의 세 시기로 구분하고, 각 시기의 특성에 대해 정치 경제 사회 문화 등 다양한 측면에서의 접근을 시도하였다. 특히, 교육적 인간상의 추출을 위하여 이들 각 시기의 주요 가치를 탐색함으로써 이와 관련한 각 시기별 인간상을 고찰하였다. 시기별로 나타나는 주요가치와 인재상은 다음과 같다. 전환기의 주요가치로는 예의와 규범을 제시할 수 있으며, 추구하는 인재상은 무실역행(務實力行)하는 자세가 강조되는 실천적 지식이었다. 산업화 시기의 주요가치로는 성실, 근면, 자조, 협동을 제시할 수 있으며, 추구하는 인재상은 경제발전에 필수적이고 강력한 직업능력을 갖춘 기능인이었다. 민주화의 주요가치로는 참여, 평등, 공존을 제시할 수 있으며, 추구하는 인재상은 경제성장의 둔화라는 위기감 속에서 국가의 생존과 번영을 위하여 이바지하는 우수한 과학인재상이었다. 각 시기별 인재상은 실용적이면서도 실천적인 유형의 인간상이 드러나고 있으며 공동체적 덕성을 중시하고 있는데, 이는 전통적인 가치관의 연속선상에서 시기별 특징을 보여주고 있는 대목이기도 하다.

본 연구는 해방 이후부터 70년대 말 산업화 시기까지 한국인이 중요시 여겼던 가치가 어떻게 변화하고 있는지 탐색하는데 목적이 있다. 두 시기에 대한 구분은 본 연구의 관점에서 볼 때, 한국사회, 혹은 한국인들의 가치체계 변화에 지대한 영향을 미친 역사적 사건을 중심으로 '전환기', '산업화 시기'로 구분하였으며 정치, 경제 및 사회적 요인들을 간략히 살펴봄으로써 시기별 가치를 살펴보고자 하였다. 연구 목적에 따라 시기별로 나타나는 주요가치와 인재상을 도출하고자 하였을 뿐만 아니라 하나의 가치가 어떻게 변모하고 있는지 탐색하였다. 시기별로 나타나는 주요가치와 인재상은 다음과 같다. 전환기의 주요가 치로는 예의와 규범을 제시하였고, 추구하는 인재상은 무실역행(務實力行)하는 자세가 강조되는 실천적 지식이었다. 산업화 시기의 주요가치로는 성실, 근면, 자조, 협동을 제시하였고, 추구하는 인재상은 경제발전에 필수적이고 강력한 직업능력을 갖춘 기능인이었다. 시기별로 지속적으로 탐색한 가치는 애국심이었다. 전환기의 애국심은 초기에는 전통적 지배구조의 붕괴와 지도자의 부재로 인하여 국가와 민족이 충의 대상이었다면 지도자의 선출과 국가의 건립 이후에는 새로운 지배구조가 형성되어 국가보다는 지도자나 상급자에 대한 충성으로 변모하는 경향을 보였다. 산업화 시기 애국심은 국가경제정책을 충실히 이행하고 반공정신으로 무장하여 북한을 압도하는 통일의지를 가지는 것 등으로 비교적 다른 시기에 비하여 목적성이 매우 뚜렷한 경향을 보였다.

The assessment of personal exposure is a critical component in population-based epidemiologic studies of air pollution. This study was conducted to apply and compare the four exposure estimation methods of individual-level to air pollution concentration in a cohort including 2,283 subjects in Gwangyang, Korea. Individual-level exposure of air pollution were estimated using multiple approaches, including average across all monitors, nearest monitor, and spatial interpolation by inverse distance weighting and kriging. The mean concentrations of $PM_{10}$, $NO_2$, $SO_2$, CO, $O_3$ by four exposure estimation methods were slightly different but not significantly different from each other. Cross-validation showed that kriging was more accurate than other exposure estimation methods because kriging has probably predicted individual exposure levels equivalent to residential locations after estimating the parameters of a model according to the spatial surface of air pollution concentration. These data support that spatial interpolation methods may provide better estimates than selecting the value from the nearest monitor and averaging across values from all monitors by reflecting spatial attributes of air pollution on personal level.

Objectives: The Coronavirus Disease 2019 (COVID-19) pandemic has caused the death of 740,000 people around the world as of August 12, 2020. Foot-and-Mouth Disease, Avian Influenza, and African Swine Fever are serious livestock diseases. Government agencies in Korea have provided ingredient information and usage instructions for disinfectants used to counter those infectious diseases. The purpose of this study was to provide information on the chemical ingredients in disinfectant products used against COVID-19 and certain livestock diseases. Methods: We collected information from the Korean government. The Central Disaster Management Headquarters and Central Disease Control Headquarters provided information on disinfectant products used against COVID-19. The Animal and Plant Quarantine Agency of Korea provided information on efficacy-certified disinfectant products for use against selected livestock diseases. Health hazard and environmental hazard information on the ingredients in the disinfectants was collected from the Korea Occupational Safety & Health Agency's Material Safety Data Sheets, and toxicity value information was collected from United States Environmental Protection Agency's CompTox Chemicals Dashboard. Results: There were 76 COVID-19 disinfectant products in use, and the most common ingredients were benzalkonium chloride (51%), alkylbenzyl dimethyl ammonium (30%), and ethanol (3%). There were 216 livestock disease disinfectant products comprised of 89 acidic, 88 oxidic, 30 aldehydic, three alkaline, and six other products. Among the 49 active ingredients used in the disinfectants that were investigated, health and environmental hazard information was provided for many of them, but only 20 chemicals had official toxicological information. Conclusion: Since the disinfectants included numerous chemicals, an understanding of their chemical characteristics could be critical to prevent unintended human or environmental exposure.

Objective: Codeine may result in death or respiratory depression in children, particularly who are rapid metabolizer of CYP2D6, therefore it should be used cautiously among children under 12 years of age. This study was to investigate the prescribing pattern of codeine among children according to the age group, prescribed diagnosis, type of medical service and medical specialties. Method: We used Korea Health Insurance Review and Assessment Service-National Patient Sample (HIRA-NPS) database. Study subjects included inpatients or outpatients, who were prescribed codeine between January, 1, 2011 and December, 31, 2011. Contraindicated use of codeine was defined as the use of codeine at least one times under aged 12. Age groups were subclassified according to the <2 years, 2-4 years, 5-8 years, and 9-11 years. Frequently prescribed diagnosis (ICD-10), type of medical service, and medical specialties were also described among codeine users under aged 12. Results: Codeine users were 6,411 inpatients (9,958 prescriptions), and 3,397 outpatients (6,258 prescriptions), respectively. Codeine prescription under 12 years of age were 2.1% (210 prescriptions) among inpatients, and 12.3% (776 prescriptions) among outpatients (p-value<0.05). Outpatient prescriptions of codeine under 12 aged were issued mostly from primary care clinics and frequent diagnosis were unspecified bronchopneumonia (51.6%), and vasomotor rhinitis (23.7%). Conclusion: This study found prescribing of codeine under 12 aged is common in outpatient and primary clinics. Nationwide and community-based efforts should be needed to reduce inappropriate prescribing among children.

Objective : The purpose of this study were to examine internal reliability and internal validity for Short Sensory Profile(SSP) and to suggest the useful criteria for sensory processing abilities in Korean culture. Methods : The Short Sensory Profile(SSP) was completed by mothers of 304 children typically developing between 3 to 10 years of age in those preschool, kindergarten and elementary school located Seoul and Gyeonggi-do. The total agency for this study was 14 facilities and the period of study was from July, 2002 to June, 2003. Kim Mi Sun(2001) translated and modified the Short Sensory Profile that Macintoshi developed and the tool for the study was used. The data were analyzed with reliability test and Pearson's correlation. Results : 1. Internal reliability of the total tests and sections was estimated by calculating Cronbach's Alphas. Reliability value of the total tests was .889. 2. For internal validity the correlations range from .131 to .575 in magnitude, suggesting that the sections of the Short Sensory Profile tap relatively unique constructs and support the factor structure developed. 3. The total score of the Short Sensory Profile(SSP) range from 118 to 190, mean and SD was 163.12, 14.87. 4. Of 403 children represented by the survey, 32 children(10.5%) met criteria for sensory processing disorders based upon parental perceptions. 5. Cut scores were determined by computing the raw score cut scores for -1 SD and -2 SD. The normal group of sensory processing abilities had score which range from 190 to 149, the probable problem group had score which range from 148 to 134, and the definite problem group had score which range from 133 to 138. Conclusion : Findings from the above study suggest that Short Sensory Profile be the screening tool for sensory processing disorders within Korean culture. Further research is needed to compare with children with the various sensory processing disabilities(PDD, LD, CP ect,).

Background: Posture balance control is the ability to maintain the body's center of gravity in the minimal postural sway state on a supportive surface. This ability is obtained through a complicated process of sensing the movements of the human body through sensory organs and then integrating the information into the central nervous system and reacting to the musculoskeletal system and the support action of the musculoskeletal system. Motor function, including coordination, motor, and vision, vestibular sense, and sensory function, including proprioception, should act in an integrated way. However, more than half of stroke patients have motor, sensory, cognitive, and emotional disorders for a long time. Motor and sensory disorders cause the greatest difficulty in postural control among stroke patients. Objects: The purpose of this study is to determine the effect of visual and somatosensory information on postural sway in stroke patients and carrying out a kinematic analysis using a tri-axial accelerometer and a quantitative assessment. Methods: Thirty-four subjects posed four stance condition was accepted various sensory information for counterbalance. This experiment referred to the computerized dynamic posturography assessments and was redesigned four condition blocking visual and somatosensory information. To measure the postural sway of the subjects' trunk, a wireless tri-axial accelerometer was used by signal vector magnitude value. Ony-way measure analysis of variance was performed among four condition. Results: There were significant differences when somatosensory information input blocked (p<.05). Conclusion: The sensory significantly affecting the balance ability of stroke patients is somatosensory, and the amount of actual movement of the trunk could be objectively compared and analyzed through quantitative figures using a tri-axial accelerometer for balance ability.

Working in a research laboratory means exposure to a wide range of hazardous substances. Several studies indicated that laboratory workers, especially working with chemicals, might have an increased risk of certain cancers. However, exposure assessment data in laboratory settings are scarce. This study was performed to examine several approaches for quantitatively assessing the exposure levels to volatile organic compounds (VOCs) among workers in chemistry laboratories. The list of 10 target VOCs, including ethanol, acetone, 2-propanol, dichlormethane, tetrahydrofuran, benzene, toluene, n-hexane, ethyl acetate, chloroform, was determined through self-administered questionnaire for six chemistry research laboratories in a university, a government-funded research institute, or private labs. From September to December 2008, 84 air samples were collected (15 area samples, 27 personal time weighted samples, 42 personal task-basis short-term samples). Real time monitors with photo ionization detector were placed during the sampling periods. In this study, benzene was observed exceeding the action levels, although all the results were below the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV). From the air sampling results, we concluded that (1) chemicals emitted during experiments could directly affect to neighbor office areas (2) chemical exposures in research laboratories showed a wide range of concentrations depending on research activities (3) area samples tended to underestimate the exposures relative to personal samples. Still, further investigation, is necessary for developing exposure assessment strategies specific to laboratories with unique exposure profiles.
