본 연구는 원예치료와 미술치료가 학교부적응 청소년의 자아개념, 내적 통제력, 불안감소에 미치는 영향을 조사하고자 실시되었으며, 그 결과는 각 치료의 효과성이 비교·분석되었다. 인천 남구에 위치한 W공업고등학교에서 대조군 15명, 원예치료군 15명, 미술치료군 15명을 주 2회씩 2001년 9월 27일부터 12월 13일까지 원예치료군에는 원예치료 프로그램을 미술치료군에는 미술치료프로그램을 실시하였다. 원예치료 및 미술치료는 각각 전문 치료사에 의해서 행해졌다. 원예치료 및 미술치료 프로그램의 효과를 알아보고자 자아개념(Self-Concept Scale), 내적 통제력 척도(Inner-Control Scale), 특성불안 척도(Trait-Anxiety Scale)을 각 프로그램의 실시전과 실시후로 조사하여 비교하였다. 원예치료군에 있어서는 자아개념척도 중 자아수용, 성격적 자아, 총 자아 긍정 항목에서 통계적으로 유의한 향상을 보였고, 특성불안척도에서는 우울 및 불안 항목에서 매우 유의한 감소를 나타내었다. 한편, 미술치료군에 있어서는 내적통제력과 특성불안척도중 자신감이 유의하게 향상된 것으로 나타났다. 이상의 결과를 종합하여 볼 때, 원예치료군은 프로그램 과정중 자기표현의 기회를 제공함으로써 자아개념이 향상되었으며, 또한, 공동작업을 하는 집단 프로그램을 통하여 내면의 불안과 갈등이 완화되었다고 판단된다. 반면, 미술치료군은 치료자와의 개인적인 상담과정을 통하여 내면의 불안과 갈등이 완화되었고, 지점토 및 칼라믹스 만들기 등 활동적인 프로그램을 통하여 내면의 감정을 통제하는 능력이 향상되었다고 판단된다. This study was conducted to evaluate the effect of HT (horticultural therapy) and AT (art therapy) on the changes of self-concept, inner control, trait anxiety of the school maladjusted adolescents. 45 school maladaptive of teenage students participated in therapy program at the W high school were randomly assigned to 3 groups: 15 for the horticultural therapy, 15 for art therapy, 15 for control group. The program were carried out from Sep. 27 to Dec. 13, 2001 as an activity group. Activity group attended twice a week for 1 hour. For evaluation of the effectiveness of each therapy, Self-Concept Scale, Inner-Control Scale, Trait-anxiety Scale were used 2 times, that is, before/after HT or AT program. According to the results, self satisfiction, personal self, and total positive self items among Self-Concept Scale were significantly improved, and tension and anxiety item among Trait anxiety Scale were significantly decreased in HT group. On the other hand, in AT group, both inner control and self confidence item in Trait-anxiety Scale were significantly improved. In conclusion, in HT group it was suggested that the improvement of self concept could be brought about by being provided the chance of self expression during program and the alleviation of inner anxiety and discord resulted from group therapy program in which joint work have been provided. In case of AT group, it was logically postulated that the alleviation of inner anxiety and discord resulted from personal counselling with AT therapist during program and the improvement of inner control was caused by active program such as painting paper clay, making color mix, and etc.

The purpose of this study was to investigate the effects of application of maker education program in school maker space on the creative problem solving ability and self-directed learning ability of elementary students. For research, we secured 18 periods of creative experience activities with 5 categories appropriate for elementary students, and integrated these activities into an elementary maker education program in school maker space. Pre and post tests were done before and after application of this maker education program to assess the changing in participants’ creative problem solving ability and self-directed learning ability. The results of this study can be summarized as follows: First, the maker education program meaningfully improved the creative problem-solving abilities of elementary school students. Second, the maker education program meaningfully improved the self-directed learning abilities of elementary school students. From interview with the students, we could know that this program made the students have self-confidence and gave them favorable impression.

소결금속섬유필터에 대한 압력손실, 먼지통과율, 부분집진효율 등의 기초 여과성능특성을 수행하였다. 두 종류의 필터가 적용되었고, 두 필터의 공극률 및 두께는 동일하고, 통기도와 여과정밀도는 다른 물리적 특성을 가지고 있다. 기초성능특성은 300×300 ㎜크기의 필터를 실험할 수 있는 필터성능실험장치를 가지고 조사하였다. 시험용 먼지로는 AC fine dust가 사용되었다. 압력손실은 여과속도와 먼지부하가 증가함에 따라 증가하였다. 먼지층 형성 초기 단계에는 여과포의 공극내에서 단일섬유 주위에 먼지입자가 응집되어 수지상 형태로 부착형성되었고, 먼지부하가 증가하여 가교형성에 의해 먼지층 형성이 진행된다. 균일먼지층 형성단계는 먼지부하가 계속 증가하여 먼지층 형성에 의해 여과포의 공극이 완전히 채워지고, 여과포 전체표면에 먼지층이 일정하게 포집되는 단계로 진행되었다. 먼지통과율은 먼지부하 초기단계에는 여과속도 증가에 따라 급격하게 증가하였고, 먼지부하가 증가함에 따라 급격하게 감소하였다. 압력손실 및 먼지통과율은 먼지부하 및 여과속도와 같은 운전변수로 상관관계식을 도출하였다. 상관관계식으로부터 계산된 압력손실 및 먼지통과율은 실험치와 잘 일치함을 알 수 있었다. 부분집진효율은 먼지부하에 따라 증가하였다. Basic filtration characteristics including pressure drop, penetration and fractional collection efficiency were investigated for sintered metal fiber filters. Two filters were applied. It was found that the porosity, weight and thickness were same, the air permeability and filtering accuracy were different. The performance test of fabric filter was investigated using a flat sheet filter testing unit, which can be applied to the filter of 300×300 ㎜ size. The test dust was AC Fine Dust. The pressure drop increased with filtration velocity and dust loading. The initial stage of dust cake formation was a growing process of particle dendrites on a single filament in the pore and the second stage was a bridge formation process with increasing dust loading. The final stage was a process of constant deposition of dust on a fabric surface under heavy dust loading conditions. The penetration sharply increased with filtration velocity in the intial stage of dust loading. It sharply decreased with dust loading, but the rate of decrease gradually diminished under heavy dust loading conditions. The pressure drop and penetration have been correlated in terms of operating variables such as dust loading and filtration velocity. The pressure drop and penetration calculated from the correlation equation have been compared with the experimental data and the agreement between the two data was fairly good. The fractional collection efficiency increased with dust loading.

Background: Rubus coreanus has been used as traditional alternative medicine for treatment of asthma and allergenic disease for centuries. Recent studies reported that the anti-inflammatory effect and immune-modulation effect of Rubus coreanus in cultured cell system or animal model. Though many previous reports proved potent mechanisms of Rubus coreanus for treatment of atopic disorders but its topical effect in clinical examination was not reported yet. Objectives: To measure the moisturizing effect of a cosmetic lotion containing 1% of R. coreanus Methods: Single application of the R. extract lotion increase skin hydration level and lasted for 24 hours. Results: Skin barrier function disturbed by tape stripping was recovered faster than non-treated control. 4 weeks of repeated treatment of the lotion significantly increase hydration level of skin from the baseline Conclusion: These results are the first clinical report for the Rubus coreanus regarding its topical treatement and moisturizing effect. Rubus coreanus extract lotion can be a good topical moisturizer for atopic skin.
