편백나무 잎 추출물로 염색한 모직물의 염색성 및 기능성
고은숙 ( Eunsook Ko ),이혜선 ( Hyesun Lee ),한충훈 ( Chunghun Han ) 한국의류학회 2019 한국의류학회지 Vol.43 No.2
This study examined the proper dyeing conditions, color fastness and functionality for wool fabrics dyed with Chamaecyparis obtusa leaf extract. FT-IR and UV-Vis spectrum analysis showed that tannin and flavonoids were contained in the extracted colorant. The dyeing of wool fabrics using Chamaecyparis obtusa leaf was good without pretreatment or mordant treatment. Optimal dyeing conditions for wool fabrics were a colorant concentration of 70%(v/v), dyeing temperature of 100℃, dyeing time of 100 minutes and dyebath pH of 5.8. Color fastness of dyed wool fabrics to washing, rubbing, perspiration was good, whereas light was grade 3. The UV protection rate and deodorization rate of wool fabrics dyed with Chamaecyparis obtusa leaf improved. Reduction rate of Staphylococcus aureus/Klebsiella pneumoniae were excellent at 99.9%. Therefore, it was confirmed that Chamaecyparis obtusa leaf can be used as environ-mentally friendly natural dye.

대학생의 진로 미결정 경험에 관한 현상학적 연구: "90년대 생 졸업예정자를 중심으로
고은숙(Eunsook Ko),이호준(Hojune Lee) 한국진로교육학회 2021 진로교육연구 Vol.34 No.3
본 연구는 대학생의 진로미결정 경험의 의미를 대학 "90년대 생 졸업예정자에 초점을 맞춰 이해하는데 목적이 있다. 이를 위해 “진로미결정은 어떻게 경험되며, 그 의미는 무엇인가?”라는 물음을 가지고 2~3회의 개별 면담을 진행하였고, 수집된 자료는 van Manen이 제안한 해석학적 현상학 연구방법에 따라 분석하였다. 분석 결과, 5개의 대주제, 12개의 주제, 53개의 의미단위가 도출되었다. 연구 결과, 5개의 대주제는 <무거운 숙제 앞에서 깊어지는 고민>, <힘들지만 넘어야 하는 현실의 장벽>, <한없이 왜소한 나의 모습>, <부모 앞에서는 진로도 의무>, <나의 길을 갈 것임> 이었다. 이를 통해 대학졸업을 앞두고 경험하는 진로미결정은 ‘본인의 능력에 대한 의심과 부모에 대한 의무감으로 진로를 무거운 숙제로 인식하면서 현실의 장벽 앞에서 고민을 거듭하고 있으나, 분명한 자기주장을 가지고 성장에의 의지만은 지키고 있는 상태’ 라는 의미를 갖는다는 결론에 도달할 수 있었다. 본 연구를 통해 얻을 수 있는 시사점은 다음과 같다. 첫째, 진로미결정을 결정과 미결정의 이분법적 시각에서 벗어나, 진로 숙고라는 제3의 관점에서 바라볼 필요가 있다. 둘째, 진로상담의 역할이 취업성공이라는 목표에만 한정되기보다 대학생들이 고민의 시간을 충분히 활용할 수 있도록 지지해주는 인식 전환이 필요하다. 셋째, 진로상담 및 진로 교육에서 부모와의 관계가 비중 있게 고려될 필요가 있다. 넷째, 진로를 ‘합리적인 결정’에만 초점을 맞춰 왔던 기존의 시각에서 벗어나 청년세대의 성장의 과정이라는 관점에서 이해할 필요가 있었다. The objective of this study is to understand the meanings and essence of university students’ experiences in career indecision by describing and interpreting them focusing on the graduates-to-be born in the 1990s. In order to do that, two to three times of separate interviews which is designed with the questions - ‘How the career indecision undergone, and what is the meaning of that?’ were conducted. Collected data which is from the interviews were analyzed by using the hermeneutic phenomenological research method suggested by van Manen. Analysis of interview data resulted in 5 major subjects, 12 topics, and 53 semantics. As the results, the five main topics are that <Deepening worries of heavy tasks>, <A barrier of reality to be difficult to cross>, <Endlessly small look of me>, <Even career is an obligation before the parents>, and <Going My Way>. The graduation senior students experience thinking of their career indecisions as heavy tasks because of their doubt of their own abilities and obligation to their parents and continue to worry before the wall of reality, but it has been come to conclusion that they keep their will of growth with clear self-assertion. Through this study, first, it is necessary to look at career indecision with the third view of career consideration, getting off the dichotomous view of decision or indecision. Second, it is needed to change the perception to support that undergraduates have enough time consider rather than the role of career counselling is limited to succeed in getting a job. Third, the relationship with parents is needed to be considered heavily in career counseling and career education. Fourth, it is necessary to understand the career in the view of youth generation’s growth process from existing point of view focused only on ‘rational decision’

This study investigated the proper dyeing conditions, color fastness and functionality of wool fabrics dyed with Zizania latifolia Turcz. We also tried to improve light fastness through treatment with benzophenone ultraviolet absorber. The dyeing of wool fabrics using Zizania latifolia Turcz was good even without pretreatment or mordanting treatment. Optimal wool fabric dyeing conditions were colorant concentration of 200% (o.w.f.), dyeing temperature of 100oC, dyeing time of 80 minutes and a dye bath pH of 3. Color fastness of dyed wool fabrics to washing, rubbing, perspiration and light was 4-5, 5, 4-4-5 (acidic), 4-5 (alkaline) and 2 respectively. The results after treatment with ultraviolet absorber for improving the fastness of daylight were improved to 3-4 grade. The UV protection rate were increased after dyeing and the deodorization of ammonia gas improved to 98%. Bacterial reduction rate (Staphylococcus aureus) of wool fabrics was excellent at 99.9%. All dye fastness (except for light fastness) was excellent; in addition, the functionality of wool fabrics dyed with Zizania latifolia Turcz also improved. The results are expected to be applied to various fields because they indicate excellent results after treatment with ultraviolet absorber for improving the fastness of daylight.

근대국어 명사형 어미의 세력 확장에 관한 일고찰 : 의사 타진 구문을 대상으로
고은숙 한국어학회 2007 한국어학 Vol.34 No.-
The aim of this paper is reveals that the distributional reduction of some connective endings caused a enlargement of the nominalizational endings in Morden Korean. The some constructions was having two types in Middle Korean. One was the type where some connective endings was used and another was the type where the nominalizational endings was used. But the former type was not used frequently in Morden Korean. So, the latter was increased relatively in Morden Korean. I try to observe the aspect and the frequency of using the connective endings and the nominalizational endings in the construction to sound a person's opinion. On investigation, the distributional reduction of connective endings had an effect on the enlargement of nominalizational endings in Morden Korean indirectly.
