본 연구는 HCI 이론을 적용하여 게임형 학습 프로그램을 평가하기 위한 준거를 개발한다. 사람들이 편리하고 즐겁게 사용하도록 하는 시스템을 개발하는 원리나 방법을 연구하는 학문인 HCI 이론은 다양한 영역의 프로그램 개발에 광범위하게 적용되어 왔다. 그리고 학습 프로그램을 평가하는 데도 널리 활용되어 왔다. 그러나 HCI 이론을 적용한 게임형 코스웨어 평가에 대한 연구는 거의 없다. 따라서, 게임형 코스웨어 평가 연구에서도 HCI 이론 적용이 필요하다. 본 연구는 HCI의 구성요소인 유용성(Usefulness), 사용성(Usability), 감성(Affect)의 관점에서 평가 준거를 개발한다. 본 연구에서 개발한 평가 준거는 게임형 학습 프로그램을 평가하는 기준으로 활용될 수 있을 것이다.

This study was conducted to investigate the contents of residual solvents and mineral components(11 kinds) in ginseng extracts with different extracting conditions(5 types) and commercial ginseng extract products(domestic, imported). Fine root was extracted with solution having various ethanol concentration after hexane treatment. Among 5 type extracts, residual solvent(hexane) was detected ginseng extracts treated ethanol mixed with hexane. But extracts that dried after soaked in hexane wasn't detected hexane. Mineral components(Al, Mn, Fe, Cu and Zn) were detected in fine root and 5 types of extracts. The contents of mineral components between fine root and extracts with various extracting conditions were similar, however, extracts that dried after soaked in hexane showed the lower amount in Al, Fe, Pb than the others. In comparison with commercial ginseng extract products(domestic, imported), the distribution pattern of mineral was similar but the contents were a little different.

This study was conducted to study the effect of horticultural therapy on the self-esteem of geriatric patients. This study was divided into two experiment. The first experiment is the effect of horticultural therapy on self-esteem depression and of the long term in geriatric patients. The subject participated in this program were 15 geriatric patients attending to Bando hospital located in Jinju. They took part in 20 horticultural therapy programs by twice a week. To investigate the effect of horticultural therapy on self-esteem scale, GDS(Geriatric depression scale), MBI(Modified barthel index), EHA(Evaluation of horticultural activity). Horticultural terapy self-esteem enhanced MBI, EHA increased and the GDS decreased gradually. The second experiment is the effect of horticultural therapy doing together with music therapy on the changes of depression and self-esteem in geriatric patients. The subjects participated in this program were 20 geriatric patients attending to Bando hospital located in Jinju. The treatments were applied on four group, group A : horticultural therapy doing together with music therapy, group B : horticultural therapy, group C : music therapy, group D : non-treatment. They took part in 20 horticultural therapy programs by twice a week and music therapy programs one time per a week. To investigate the effect of horticultural therapy on Self-esteem scale, GDS, EHA. According to the results, treatments was effectiness on group A, B and C in self-esteem scale, GDS and EHA, but not on group D.

본 연구는 초등학교 수학과 도형 영역에서의 수준별 학습을 지원하기 위한 어드벤처 게임형 학습 프로그램을 개발하는 것이다. 제7차 교육과정에서는 학생의 능력, 적성, 필요, 흥미 에 대한 개인차를 최대로 고려하는 수업을 통하여 학생 개개인의 성장 잠재력과 교육의 효율성을 극대화할 수 있도록 수준별 교육과정을 도입하였다. 그러나 수준차가 심한 다인수 학급체제에서 학생들의 개인차를 고려한 개별화 학습을 실시하여 교육의 수월성을 추구하기에는 많은 어려움이 있다. 따라서, 본 연구는 van Hiele 이론을 적용한 수준별 게임 학습을 제공하고, 학습자들의 흥미와 관심을 높일 수 있는 어드벤처 게임형 학습 프로그램을 개발하였다. 본 프로그램은 심화 보충학습이 필요한 학습자들에게 개인차를 고려한 수준별 학습을 지원하여 학업 성취도를 높일 수 있을 것이며 공간 지각 능력이 필요한 도형 학습에서 다양한 조작활동을 제공함으로써 학습자들의 공간 감각을 기를 수 있을 것이다.

We were carried out to monitor pesticide residues in herbal medicine. In Korea Pharmacy, these are no critics for pesticides except 5 kinds of organic chlorines (BHC, DDT, Aldrin, Endrin, Dieldrin) and heavy metals. We analysed 53 kinds of pesticides consisted of 14 kinds of organochlorines, 20 kinds of organophosphoruses, and 19 kinds of pesticides estimated endocrine disruptor on 373 samples consisted with 30kinds of herbal medicine. In this study, Domestic, Chinese and Japanese herbal medicines were tested with GC/ECD, GC/NPD and then confirmed with GC/MSD. Recoveries were 75～110% in ECD detector and 76～97% in NPD detector. Detection limits were 0.004～0.064ppm in ECD detector and 0.006～0.094ppm in NPD detector. Organochlorines and others were not detected in samples.

The simultaneous analysis of multi-residual pesticides was developed using a gas chromatography (GC) method. In this study, a simple and reliable methodology was improved to detect 154 kinds of pesticides in ginseng extract sample by using a liquid-liquid extraction procedure, open column chromagraphy and chromatographic analysis by GC electron capture detector (ECD) and GC nitrogen-phosphorus detector (NPD). The 154 kinds of pesticides were classified in 4 groups according to the chemical structure. The extraction of pesticides was experimented with 70% acetone and dichloromethane/petroleum ether in order, and cleaned up via open column chromatography (3×30㎝) packed with florisil (30g, 130℃, 12hrs). The final extract was concentrated in a rotator evaporator at 40℃ until dryness. Then the residue was redissolved to 2㎖ with acetone, and analyzed by GC-ECD and GC-NPD. The applied concentration of pesticides was over 1~10㎍/㎖. The recovery tests were ranged from 70.7% to 115.2% with standard deviations between 0.3 and 5.7% of the standard spiked to the ginseng extract sample (Group Ⅰ~Ⅳ). The limit of detection (LOD) ranged from 0.001 to 0.099㎍/㎖ (Group Ⅰ~Ⅳ). The 9 kinds of pesticides were not detected. The developed method was applied satisfactory to the determination of the 154 kinds of pesticides in the ginseng extract with good reproducibility and accuracy.
