지적장애인의 작업수행능력과 지역사회적응수준과의 상관연구
The purpose of this study is to find out the correlation between work performance and community integration skills of intellectual disabilities, and contribute to the research about their employment and its maintenance. The results of job assessment given to intellectual disabilities from special schools and classes in Daegu from 2009~2011 are used as a sample. Community Integration Skills-Assessment(CIS-A) and Work Sample Test including AMOS #2(TAP #6), Purdue Pegboard, and Work Activities #206, #303 were conducted on 122 students. Students with severe disabilities who had many difficulties with performance were excluded from the study, and thus 105 participants were used. Compared to a general group, most participants' performance skills were below average. With in the group of disabled students, however, average and above average results were found. The level of community adaption ability was also lower in the general group, in the disabilities group however, more than 98% of participants were above-average. After analyzing the correlation between work performance and community integration skills of intellectual disabilities, only a few secondary factors of community integration skills and work performance were statistically non-significant but most of the primary factors were significant. Currently vocational rehabilitation systems know the importance of community integration skills because of intellectual disabilities' employment and they place emphasis on educations and training to it. For their employment and its maintenance, therefore, this research newly reveals the importance of adaptive skills and can give direction for development and application of vocational rehabilitation programs. As work performance is limited to packaging and fine and gross hand motor skills, further research should be expanded to other areas. Further research about education contents and their placement results are required, though these are not dealt with in this study.

이 연구는 대학생의 성인애착과 관계중독 간의 관계에서 마음챙김이 매개하는지 알아보고자 하였다. 이를 위해 서울, 경기도, 강원도, 충청도에 소재하는 4개 대학의 4년제 대학생 300명을 대상으로 성인애착, 마음챙김, 관계중독에 대한 설문을 실시하였다. 성인애착을 측정하기 위해 Brennan 등(2000)이 문항반응이론을 활용하여 개발한 성인애착유형검사(ECR-R)인 친밀관계경험척도를 김성현(2004)이 번안하여 확증적 요인분석을 통해 구인타당도를 검증한 척도를 사용하였다. 마음챙김은 위빠사나 명상이론에 근거해서 Brown과 Ryan(2003)이 개발한 마음챙김 주의-자각척도를 사용하여 박성현(2006)이 타당화한 척도를 사용하였다. 관계중독은 Susan(2005)이 임상경험을 바탕으로 제작한 40문항의 임상질문지를 이수현(2009)이 타당화한 척도를 사용하였다. 이 연구의 결과를 요약하면 다음과 같다. 첫째, 각 변인들 간의 상관관계를 살펴보면 성인애착은 관계중독과 유의한 정적상관이 있는 것으로 나타났다. 성인애착은 마음챙김과 유의한 부적상관이 있는 것으로 나타났으며 마음챙김과 관계중독과는 유의한 부적상관이 있는 것으로 나타났다. 둘째, 성인애착과 관계중독의 관계에서 마음챙김의 역할을 분석한 결과, 성인애착과 관계중독을 마음챙김이 부분매개하는 것으로 나타났다. 이것은 성인애착이 관계중독에 직접적인 영향을 미치기도 하지만 성인애착이 높을수록 마음챙김이 낮아지고, 마음챙김이 관계중독을 감소시키는 간접효과가 있다는 것을 의미한다. 특히 성인애착의 하위요인인 애착불안은 관계중독 간의 관계에서 마음챙김이 부분매개 하는 것으로 나타났다. 마지막으로, 이와 같은 결과를 바탕으로 본 연구의 의의 및 시사점과 제한점에 대해 논의하였다. 주요어 : 성인애착, 관계중독, 마음챙김 The study sought to ascertain whether the mindfulness mediates in the relations between adult attachment and relationship addiction of university students. For this, a survey was conducted on adult attachment, mindfulness and relationship addiction among 300 university students from 4 university located around 4 provinces; Seoul, Gyeonggi-do, Gangwon-do and Chungcheong-do. To measure the adult attachment, Kim(2004)’s adaption of Brennan et al.(2000)’s the Experiences in Close Relationships Scale-Revised: ECR-R which utilizes the item response theory was used. Brown and Ryan(2003)’s Mindfulness Attention Awareness Scale, adapted and validated by Park(2006), was used as mindfulness scale, based on Vipassana Mediation theory. Susan(2005)’s 40-item questionnaire based on clinical experience, validated by Lee(2009) was used as relationship addiction scale. The findings are summarized as follows. Firstly, examining correlation analysis results between variables revealed a significant positive correlation between adult attachment and relationship addiction. The adult attachment was found to negatively associated with mindfulness while it was positively associated with relationship addiction and the mindfulness was found to negatively associated with relationship addiction. Secondly, the analysis result of mindfulness’s role in the relation between adult attachment and relationship addiction discovered that mindfulness partially mediates adult attachment and relationship addiction. This suggests that adult attachment not only affects relationship addiction directly, it raises the mindfulness. Which, in turn, the relationship addiction, having an indirect effect on relationship addiction. Especially, the mindfulness partially mediates attachment anxiety, which is sub-factor of adult attachment, and relationship addiction while the mindfulness has no mediating effect in the relationship between attachment avoidance and relationship addiction. Finally, a discussion of implications, suggestions for future research and limitations are presented. Keywords : Adult attachment, Relationship addiction, Mindfulness.

In fact, discrimination is very severe depending on whether or not Nongak is designated as an intangible cultural asset at the site of the transmission of Nongak. So I was curious. Among many nongak, only a small number of nongak have been designated as intangible cultural assets. That's how I started my research. This study reviewed the process of designating a holder in the field of nongak at the time of the designation of intangible cultural assets of the state. So far, there have been six Nongak designated as intangible cultural properties, starting with Jinju Samcheonpo Nongak in 1966, Pyeongtaek Nongak and Iri Nongak and Gangneung Nongak, in 1985, Imsil Pilbong Nongak in 1988, and Gurye Jansu Nongak in 2010. Nongak, which has been designated as a national intangible cultural asset, is currently representative of the area. Nongak in each region, which is currently designated as an intangible cultural asset, was mostly related to the recruitment of professional Nongak celebrities and cultural heritage Committee members. The planning of the Cultural Heritage Committee and the active activities of the parties led to the designation of the holder. Nongak is considered to be different, representing each region, but the distinction was meaningless in the process of designating intangible cultural assets. It was selected and reconstructed as necessary in the a hereditary genealogy or in the activities of the holder. Various forms of nongak have also been changed to the practice of performing pangut. Above all, it was shown that the transmission of Nongak was more focused on individual owners than on organizations in the process of designating intangible cultural assets, and the importance of the position and role of Nongak was recognized. 본 연구는 국가무형문화재 지정 당시 농악분야의 보유자 지정과정을 검토하였다. 지금까지 국가무형문화재로 지정된 농악은 1966년 ‘진주삼천포농악’을 시작으로 1985년 ‘평택농악’·‘이리농악’·‘강릉농악’, 1988년 ‘임실필봉농악’, 2010년 ‘구례잔수농악’까지 모두 6개다. 국가무형문화재로 지정된 농악은 현재 그 지역을 대표하는 존재로 자리하고 있다. 현재 무형문화재로 지정되어있는 각 지역의 농악은 대부분 전문적으로 활동한 농악예인들의 지역 영입과 문화재위원이 관련되어 있었다. 문화재위원의 기획과 당사자들의 적극적인 활동은 보유자 지정으로 이어졌다. 농악이 각 지역을 대표하며 각기 다른 것으로 여겨지지만 실제 무형문화재 지정과정에서는 그 구분이 무의미하였다. 전승계보나 보유자의 활동에서 필요에 의해 선택되어 재구성되기도 하였다. 또한 다양한 형태의 농악은 대회용 판굿 연행의 양상으로 변화되기도 하였다. 무엇보다 무형문화재 지정과정에서 농악의 전승양상은 단체보다 보유자 개인에게 집중되어 있었음을 알 수 있었으며, 그만큼 농악의 전승에 있어 보유자의 위치와 역할에 대한 중요성을 인식할 수 있었다.
Many of the persistent organic pollutants (POPs) had been banned several decades ago. However, most of these compounds, including organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) have been frequently detected in various environmental media, biota, and human biological samples worldwide. In addition, new POPs - such as polybrominated diphenyl ethers (PBDEs) - have also been frequently detected because of their extensive use and bioaccumulative characteristics. Among various toxic effects of POPs, endocrine disruption that may link to changes in growth and development, metabolic disorders and obesity is one of the important adverse health effects. Thyroid hormones and adipokines are key hormones related to normal development and energy metabolism. Early life stages are particularly susceptible to these hormones and the endocrine disruption. Endocrine disrupting effect during these sensitive periods may lead to permanent adverse effects in later stages of life. Therefore, association between POPs exposure and endocrine disruption among the susceptible human populations, including fetuses, newborn infants, and pregnant women deserves scrupulous investigation. However, current understanding on endocrine disruption effects of POPs is still limited among these vulnerable populations and previously reported results are frequently controversial. In order to address these issues, the present study investigates the association between POPs exposure and thyroid hormones or adipokine levels among pregnant women or matching newborns. For this purpose, pregnant women and their matching newborn infants without any known occupational exposure pathways to major POPs were recruited from five university hospitals located in four cites of South Korea in 2011-2012 (Children’s Health and Environmental Chemicals of Korea Panel: CHECK Panel). Maternal and cord blood serum samples were collected at delivery, and breast milk samples were collected between 15th and 30th day of lactation. Target chemicals including 19 OCPs, 19 PCBs, and 19 PBDEs, and hormones were measured in serum samples, and chemicals which were detected > 60% and sum of the isomers (ΣPCB, ΣPBDE, Σdichlorodiphenyltrichloroethane (DDT), Σchlordane (CHD), Σhexachlorhexane (HCH)) were used in statistical analysis. This study was conducted in three parts. In the first part, the associations between major groups of POPs and thyroid hormone balances among pregnant women were assessed. Blood samples were collected within a day before delivery from 105 pregnant women of CHECK Panel in 2011. Serum was then analyzed for target POPs along with five thyroid hormones (free and total T3 and T4, and TSH). Several PCBs, such as CB 28, -52, and -118, showed negative associations with T3 or T4. BDE 47 and ΣPBDEs showed significant associations with T3 or T4. For OCPs, ΣDDT and hexachlorobenzene (HCB) were generally associated with the reduction of T3 or T4. While the thyroid hormone levels of all subjects were within the reference range, the levels of exposure to several target POPs were clearly associated with alteration of thyroid hormone balance among pregnant women without any known occupational sources of exposure. In the second part, the associations between prenatal exposure to major POPs and thyroid hormone levels among newborn infants were investigated (n=104). As thyroid hormone levels in cord blood serum could be influenced by the input of thyroid hormones of maternal origin, thyroid hormone concentrations of the matching mothers at delivery were adjusted. In addition, TSH measured in bloodspot samples of newborn infants on 2 day after birth was used. In cord serum, BDE47, BDE 99, ΣCHD, and p,p'-dichloro-diphenyldichloro-ethylene (DDE) showed significant positive associations with cord blood serum or bloodspot TSH. At the same time, p,p'-DDE and HCB showed negative association with total T3 and T4 in cord serum, respectively. Maternal exposure to β-hexachlorhexane (β-HCH), ΣCHD, ΣDDT, or p,p'-DDE were also associated with neonatal thyroid hormones. Although the sample size was small and the thyroid hormone levels of the subjects were within the reference range, our observation clearly supported endocrine disrupting effects of several POPs among newborn infants at the levels occurring in the general population. In the third part, the associations between several kinds of maternal POPs exposure and the levels of adipokines in breast milk were investigated (n=50). As the effect marker hormones related to obesity and diabetes, leptin and adiponectin in breast milk were selected. Significant negative association between breast milk leptin concentration and oxy-chlordane (oxyCHD), ∑CHD, BDE 47, or CB 138 levels in maternal serum was observed. P,p’-DDT, oxyCHD, tNCHD, ∑CHD, BDE 47, CB 153, or ∑PCB body burden were significantly associated with increased adiponectin concentrations in breast milk samples. Thus, the results of this study provide a line of evidence that POPs at the current level of exposure may link to the alteration of lipid metabolism, which might possibly lead to obesity in later stages of life. Through a series of cross-sectional studies, it was established that the current levels of exposure to POPs could be associated with the disruption in thyroid hormones and lipid metabolism among pregnant/lactating women or newborn infants. These findings are supported by previous experimental studies, but should be confirmed in prospective birth cohorts with a greater number of subjects for the biological significance. Considering the importance of thyroid hormones and adipokines during gestation and early life stages, health implication of endocrine disruption effects by low level POPs exposure deserves further investigation.

고온초전도체의 터널 접합 특성을 이용한 3단 소자 응용 및 Intrinsic Josephson 효과 연구
고온초전도체에 대한 tunneling 특성을 조사하기 위해 금속/고온초전도체, 강자성체/금속/고온초전도체 및 유기물/고온초전도체의 tunnel 접합을 제작하고 tunneling spectroscopy를 통해 고온초전도체의 pairing symmetry를 논의 하였다. 초전도 박막은 molecular beam epitaxy(MBE) 장비로 제작된 Bi_(2)Sr_(2)CaCu_(2)O_(8+d) (BSCCO) 박막과 pulsed laser deposition(PLD) 장비로 제작된 YBa_(2)Cu_(3)O_(y) (YBCO) 박막을 사용하였다. Au/BSCCO 접합은 tunneling 전도 특성 (dI/dV)을 통해 에너지 갭 특성을 관측하였다. Zero bias 근처에서는 전도성의 향상을 나타내는 zero bias conductance peak (ZBCP)를 관찰하였다. ZBCP의 온도 의존성 및 방향 의존성은 고온초전도체의 d-wave 적인 에너지 갭 대칭성을 나타내는 증거이다. 금속/고온초전도체 경계면에서의 Andreev 반사 이론을 통해 설명할 수 있다. 강자성체/금속/고온초전도체 tunnel 접합 형태로 제작된 Co/Au/YBCO tunnel 접합을 이용하여 실험한 결과, spin polarized quasiparticle(QP) 주입에 의한 tunnel 전도 특성은 Andreev 반사를 감소시키는 효과를 가져왔다. 이는 spin에 의한 QP polarization의 영향 때문이다. 새로운 터널 접합 형태의 광전도성 유기물/고온초전도체 (Cu-Pc/BSCCO) tunnel 접합을 이용하여 tunnel 특성을 측정하였다. 경계면에서서 ZBCP가 금속/고온초전도체 터널접합에 비해 broad한 특성을 보임을 관측하였다. ZBCP의 관측은 d-wave 고온초전도체 경계에서의 Andreev 반사를 반영한 tunneling으로 확인되었다. UV광 조사에 의한 ZBCP의 향상은 photoexcite된 polaronic QP들의 효과에 의해 변화를 보였다. 이와 같은 tunnel 접합 특성들을 이용하여 고온초전도체의 3단 소자에 대하여 연구하였다. QP 주입소자의 낮은 전류 이득과 spin 주입 소자의 spin 경계면 degradation등의 단점을 극복할 수 있는 방법으로 유기물을 이용한 3단 소자를 처음으로 제작하여 polaronic QP 주입 고온초전도 3단 소자 연구를 하였다. 소자 제작을 위해 전류 주입 층으로 유기물 Cu-Pc 층을 BSCCO 박막 위에 증착 하였고 전극으로 Au층을 올려 초전도성 3단 소자를 제작하였다. 제작된 유기물/초전도체 소자의 소자의 전류-전압(Ⅰ-Ⅴ) 특성은 주입전류에 의해 효과적으로 조절 되며 높은 전류 이득을 얻을 수 있었다. 위 결과들은 polaronic QP 주입에 의한 비평형 효과에 의해 설명 될 수 있으며 UV광 조사에 의한 전류 이득의 향상은 광 조절 소자로의 가능성을 보였다. Anisotropic한 BSCCO 단결정으로부터 intrinsic Josephson 접합의 수송 특성 및 마이크로파 특성에 관해 연구하였다. 측정 샘플들은 BSCCO 단결정 위에 mesa 형태로 제작하였다. Mesa 층에 수직인 c-축 방향으로의 QP 주입은 intrinsic Josephson 접합의 Ⅰ-Ⅴ 특성에서 다수의 branch 구조를 형성하며 branch 구조에 따라 강한 마이크로파 방출 특성을 보였다. 전류-전압 곡선의 많은 branch 수는 mesa내 존재하는 intrinsic Josephson 접합의 수와 대응되며 Ⅰ-Ⅴ 곡선의 negative resistance는 c-축으로 주입되는 QP들에 의해 형성된 비평형 효과에 의해서 형성됨을 설명하였다. 마이크로파 특성은 세가지 다른 모드 특성을 보였으며 negative resistance 영역에서 강한 마이크로파 자발 방출 특성은 Josephson plasma 여기에 의해 설명될 수 있다. 두 mesa 구조를 mutual phase interaction 하였을때 coherent한 마이크로파 자발방출의 synchronize 효과를 실험적으로 관측하였다. To study the tunneling mechanism of high Tc superconductor (HTSC), we measured the tunneling specta at metal/HTSC (Au/YBa_(2)Cu_(3)O_(y)(YBCO), Au/Bi_(2)Sr_(2)CaCu_(2)O_(8+d)(BSCCO)) tunnel junctions, ferromagnet/metal/HTSC (Co/Au/BSCCO) tunnel junctions, and organic material/HTSC (copper Ⅱ phthalocyanine (Cu-Pc)/YBCO, Cu-Pc/BSCCO) tunnel junctions. Tunneling conductance spectrum showed a zero bias conductance peak (ZBCP) at Au/[110]YBCO tunnel junction. However it was not observable at Au/[100]YBCO tunnel junction. These evidences indicate that HTSC has a d-wave pairing symmetry. For the Co/Au/BSCCO tunnel junction, the suppressed ZBCP was observed and it may be interpreted by the modification of Andreev reflection due to the presence of the exchange interaction. In the Cu-Pc/BSCCO tunnel junction, ZBCP appearance means Andreev scattering of polaronic QP from organic Cu-Pc at organic material/d-wave superconductor junction. Under the UV excitation, the enhancement of ZBCP may be interpreted due to the photo-generated carriers in Cu-Pc. By using tunnel junctions we studied three terminal devices for the application of HTSC. In order to obtain high current gain, we fabricated a new polaronic quasiparticle(QP) injection device using an organic photoconductor of copper Ⅱ phthalocyanine (Cu-Pc). The observed current gain was about 2.5 due to a nonequilibrium effect by polaronic QP injection. Under the UV excitation, we observed the enhanced current gain about 2.8 dueto an additional nonequilibrium effect by the photogenerated carrier in Cu-Pc. For the application of high frequency devices, we studied the intrinsic Josephson junctions. We fabricated the micron-size mesa structures using a BSCCO single crystal. To excite Josephson plasma, we carried out the c-axis QP injection into the BSCCO mesa and measure the microwave emission from centimeter to millimeter wave range. We observed three different microwave emission modes depending on the bias voltage in the hysteretic current-voltage characteristics; Josephson emission, nonequilibrium broad emission and sharp coherent emission. In order to increase the microwave emission power, mutual phase interactions between two-mesas structures of BSCCO intrinsic Josephson were studied. The measured output power of the two-mesa structures of intrinsic Josephson junctions was almost four times larger than that of the single junction, indicating an exact phase-locking state between the two intrinsic Josephson junctions. It was explained in the framework of the Josephson plasma excitantion model due to quasiparticle injection.
