        집단미술치료의 치료요인 척도 개발

        남정 한국미술치료학회 2012 美術治療硏究 Vol.19 No.3

        The purpose of this study develop evaluative criteria for therapeutic factors in group art therapy to enable art therapists to understand the effects of the therapeutic factors in the process of therapies, let them sympathize with the counsellee and consequently derive positive changes. Detailed contents such as the four factors of group art therapy, and the definition and changes of problems set based on the analysis of the precedent researches on the therapeutic factors in group art therapy, and 10 art therapy experts were subjected to a survey through an open questionnaire for the preparation of a preliminary problem set. By analyzing the materials, the first preliminary problem set was developed, comprising five factors by adding art media-a. The first preliminary problem set finalized by expert evaluation was composed of 184 problems, after modification based on reference to and review of related questions used in the therapeutic criteria of Kivlighan, Mullton, Brossart(1996) and Yalom(1975). 295 art therapists, and art therapy trainees were subjected to analysis. As a result, stable existence of four therapeutic factor criteria were extracted 56questions 876 - a creditable level - in the case of help through interaction, and over .90 in the case of other factors. The propriety of the criteria was also proved to be within a desirable range. 본 연구는 집단미술치료의 치료요인 척도를 개발하여 미술치료자가 미술치료 장면에서 치료요인이 미치는 효과를 인식하고, 이를 적절히 활용하여 내담자를 이해하고 내담자의 긍정적인 변화를 가져올 수 있도록 하는것이다. 집단미술치료의 치료요인 선행연구 분석을 통해 설정한 집단미술치료의 4가지 치료요인에 대해 개인면접을 통한 개방형 질문지를 10명의 미술치료전문가에게 실시하여 자료를 분석한 결과 미술매체를 첨가하여 5개의 요인으로 구성하였다. Kivlighan, Mullton과 Brossart(1996), Yalom(1975)의 치료요인 척도에서 사용된 관련된 문항의 내용을 참고, 검토하여 집단미술치료의 치료요인에 적합한 문항으로 수정하고, 1차 예비문항을 개발하여 전문가의 평정을 거쳐 184문항을 개발하였다. 295명의 미술치료자와 미술치료 수련생 대상으로 분석을 실시하여 56문항 4개의 하위요인이 안정적으로 존재함을 확인하였다. 상호작용을 통한 도움의 경우 신뢰도가 .876으로 양호한 신뢰도를 보였으며, 이 요인을 제외한 다른 요인들은 신뢰도가 .90을 넘고 있어 아주 양호한 신뢰도를 가진다고 볼 수 있다. 또한 집단미술치료의 치료요인 척도의 내용타당도를 검증한 결과 비교적 양호한 타당도를 나타내었다.

        갈변억제제 첨가에 따른 열풍건조 수프용 감자 플레이크 품질 특성

        남정(Jung-Hyun Nam),천지연(Ji-Yeon Chun) 한국식품영양과학회 2021 한국식품영양과학회지 Vol.50 No.2

        본 연구에서는 건조 시 발생하는 감자의 갈변현상을 억제하고 품질 높은 건조 감자를 제조하기 위해 제주에서 재배되는 탐나 감자를 NaCl과 CaCl₂ 용액에 처리한 뒤 열풍건조 하여 색도, 갈변도, pH, 수분활성도, 경도, 비타민 C 함량을 측정하였다. 갈변억제제를 처리함에 따라 명도와 적색도가 증가하였고 갈변도는 감소하였다. 처리 농도가 증가함에 따라 갈변도가 더욱 감소하였고 이는 염 처리에 따른 당 함량 감소와 그에 따른 갈변현상 억제일 것으로 추측된다. 수분활성도는 대조구와 갈변억제제 0.05% 처리에서 비슷한 수준을 나타내었지만, 농도가 0.1% 이상으로 증가할수록 수분활성도가 감소하였다. NaCl과 CaCl₂를 처리한 것이 삼투현상을 촉진하여 수분활성도가 감소하였을 것으로 추측된다. 비타민 C 함량은 CaCl₂ 처리구의 경우 대조구보다 낮은 함량이었으며, NaCl 처리구의 경우 0.1% 농도까지는 대조구보다 높은 함량이었지만 0.15% 농도에서는 낮은 함량을 나타내었다. 처리 용액의 농도가 증가할 경우 비타민 C 함량이 감소하여 영양분이 손실되는 단점이 있었다. 갈변억제제(NaCl, CaCl₂) 용액을 이용한 데치기와 열풍건조 공정을 통하여 수분 특성을 제어할 수 있고 이에 따라 저장성이 증가한 건조감자를 제조할 수 있었다. 또한 색도 개선과 갈변도 감소로 갈변현상을 억제할 수 있음을 확인하였다. NaCl과 CaCl₂ 등의 갈변억제제 처리와 데치기 공정을 통해 품질 높은 건조감자를 제조할 수 있을 것으로 생각된다. Potato browning has been known to be caused by polyphenol oxidase. Another reason for browning is the Maillard reaction during the heating process. The polyphenol oxidase activity can be reduced through blanching or by using browning inhibitors such as ascorbic acid, CaCl₂, NaCl, citric acid, and oxalic acid. This study examined the effects of browning inhibitors (NaCl and CaCl₂) and blanching treatment on the qualities of Jeju Tamna potatoes. Various concentrations (0.05%, 0.1%, and 0.15%) of NaCl or CaCl₂ were added in the blanching and soaking process, and then the potatoes were dried by hot air (58°C, 16 hours). The brown index after NaCl and CaCl₂ treatments were seen to be lower than without treatment. The brown index of potatoes decreased with increasing concentration of NaCl. However, the brown index did not show a significant variation with changes in the CaCl₂ concentration. The L* and a* value of potato color tended to increase depending on the increase in the concentration of the browning inhibitor, while the pH and water activity tended to decrease. The hardness showed no significant variation between the NaCl and CaCl₂ treatments. Vitamin C levels decreased as the concentrations of NaCl and CaCl₂ increased. The NaCl and CaCl₂ treatments for potatoes were useful for improving color, inhibiting browning, and decreasing pH and water activity, but there was a nutritional problem as vitamin C levels decreased as browning inhibitor concentration increased.

      • 성인 지역사회 폐렴의 원인 미생물에 대한 전향적 다기관 연구 : 마이코플라즈마와 클라미디아의 역할

        주철,윤하정,남정,문미선,조영걸,우준희,강재명,신완식,김양리,김민자,정희진,이환종,김유겸 대한감염학회 2001 감염 Vol.33 No.1

        Background : The purpose of this study is to develop a rapid and sensitive method to detect M. pneumoniae and C. pneumoniae. In addition, we prospectively investigated the prevalence of M. pneumoniae and C. pneumoniae infections in community-acquired pneumonia. Methods : The nasopharyngeal aspirates were collected from truly 1997 to April 2000. PCR or nested PCR techniques were used to detect causative agents. RFLP and nucleotide sequence analysis were performed to study molecular epidemiology. Furthermore, feasibility of one-step technique to detect two microorganisms was tested by multiplex PCR. Results : Of 250 clinical specimens, 23 (9.2%) specimens were positive for M. pneumoniae and 33 (13.2%) for C. pneumoniae, including one dual-infected specimen. Most M. pneumoniae infection occurred during the colder months of the year. C. pneumoniae infection was predominantly found from December to February. Conclusion : The results indicate that M. pneumoniae and C. pneumoniae infections are frequently found from patients with community-acquired pneumonia. (Korean J Infect Dis 33: 15-23, 2001)

        This analysis is to review whether PSD(Platform Screen Door) installed in local subway stations secures amenities of sound environment among the elements of developing pleasant station surroundings. Since there has been no specific noise standard for indoor subway station in the country, would like to suggest suitable criteria based on research on other similar domestic and foreign cases. Also, this study aims at whether PSD meets the noise standards of platforms and affects noise reduction through simulation of before and after installing.

        IGHG2 and FCGRs Polymorphisms in Patients with Generalized Aggressive Periodontitis

        남정,최점일,박경숙 한국유전학회 2006 Genes & Genomics Vol.28 No.1

        Generalized aggressive periodontitis (GAP) is an inflammatory disease characterized by the rapid periodontal tissue destruction initiated by bacterial infections. Interactions between FcγReceptors (FCGRs) and IgG-opsonized bacteria play a major role in host immune defense, which may predispose to the development of GAP. We investigated genetic effects of functional polymorphisms of the FCGRs, IGHG2 genes, and the FCGRs haplotypes on GAP. Four polymorphisms, FCGR2A His131Arg, FCGR3A Phe158Val, FCGR3B, and IGHG2, were genotyped by using polymerase chain reaction-allele specific primers in 93 GAP patients and in 142 healthy controls. The genotype and allele frequencies of FCGR2A His131Arg, FCGR3A Phe158Val, FCGR3B, and IGHG2 polymorphisms did not show significant differences between the GAP patients and the controls. Frequency of individuals carrying both FCGR3A 158*Val and FCGR3B *2 alleles were higher in the patients than in the controls (40.9% vs 30.3%). In the never-smoker group FCGR3B*2 carrier frequency was significantly higher in the GAP patients than in the controls (70.8% vs 54.7%; odds ratio [OR] = 2.0, 95% confidence interval [CI] = 1.02-3.98, p = 0.044). And individuals having both FCGR3A 158*Val and FCGR3B*2 alleles were significantly more prevalent in the patients than in the controls (46.2% vs 25.6%; OR = 2.5, 95% CI=1.25-4.96, p = 0.008). Haplotype frequencies of FCGR2A, FCGR3A, and FCGR3B were not found to be different between the patients and the controls. These results suggest that each of FCGR2A, 3A, 3B, and IGHG2 polymorphisms alone was not sufficient for the development of GAP, but that combined genes of FCGR3B *2 and FCGR3A 158*Val were associated with never-smoker GAP patients, in particular.
