본 연구에서는 교대로 운전되는 두 개의 UV/광촉매 반응기로 구성된 폐가스 처리시스템의 운전단계와 단계별 광촉매의 비활성화의 상관관계를 사용된 광촉매에 대한 기기분석을 통하여 규명하였다. 선행연구[Lee와 Lim, Korean Chem. Eng. Research, 59(4), 574-583 (2021)]의 광촉매 반응기 시스템 운전에 사용되지 않은 광촉매를 담지한 다공성 SiO₂ 담체(A4), 1회 운전하는 동안 사용되고 재생을 경험하지 않은 광촉매를 담지한 다공성 SiO₂ 담체(A1), 2회 운전에 사용되고 1회 재생된 광촉매를 담지한 다공성 SiO₂ 담체(A2) 및 3회 운전에 사용되고 2회 재생된 광촉매를 담지한 다공성SiO₂ 담체(A3)와, 1차 재생(AD1) 또는 3차 재생(AD3)된 광촉매를 담지한 다공성 SiO₂ 담체에 대한 BET 분석, SEM, XPS, SEM-EDS 및 FTIR 분석 등을 수행하여, 광촉매를 담지한 다공성 SiO₂ 담체의 비활성화 및 재생 특성을 포함하는 특성 분석을 수행하였다. 그 결과로서, 3회 이상의 여러 번 재생을 수행하는 광촉매의 적정 재생 온도를 200℃ 미만으로 도출하였다. 이러한 광촉매의 적정 재생 온도는 BET 분석결과에서 도출된 기공에 흡착된 에탄올 산화분해 중간생성물의 대부분이 완전 분해가 되어 기공이 재생되는 재생 온도와 거의 일치하였다. 특히, XPS 분석 결과는, 선행 연구[Lee와 Lim, Korean Chem. Eng. Research, 59(4), 574-583 (2021)]에서 광촉매 반응기의 첫 번째 운전 후에 광촉매의 미세한 비활성화가 발생하였음을 나타내었다. 또한, XPS 분석 결과는, 선행연구[Lee와 Lim, Korean Chem. Eng. Research, 59(4), 574-583 (2021)]에서 광촉매 반응기의 두 번째 운전에서 비교적 큰 광촉매의 비활성화가 발생하여 첫번째 운전성능보다 약 5%만큼 못 미치는 에탄올과 황화수소 각각의 제거효율을 초래하였으나, 세 번째 운전에서의 에탄올과 황화수소의 제거효율은 두 번째 운전에서의 에탄올과 황화수소의 제거효율 실험 결과와 거의 비슷하였다는 연구 결과와 일치하였다. 한편, AD3를 사용하여 선행연구[Lee와 Lim, Korean Chem. Eng. Research, 59(4), 574-583 (2021)]에서와 같은 광촉매 반응기의 네 번째 운전을 수행할 것을 가정하면, 두 번째 운전에서보다 더 큰 광촉매의 비가역적 비활성화의 발생으로 인하여 에탄올과 황화수소 제거효율이 가장 크게 저하되리라 예상되었다. In this study, the correlation between operating stages of waste air-treating system composed of two alternatively-operating UV/photocatalytic reactors, and the deactivation of photocatalyst used in each operating stage, was investigated by instrumental analysis thereon. The repeated deactivation and subsequent re-generation of photocatalyst used in the waste air treating system of previous investigation performed by Lee and Lim (Korean Chem. Eng. Research, 59(4), 574-583(2021)), were characterized on virgin photocatalyst-carrying porous SiO₂ media (A4), used photocatalystcarrying porous SiO₂ media (A1, A2 and A3) collected from the corresponding photocatalytic reactor upon 1^st, 2^nd, and 3^rd run, respectively, regenerated photocatalyst-carrying porous SiO₂ media upon 1 time-run (AD1) and 3 times regenerated photocatalyst-carrying porous SiO₂ media upon 3 time-runs (AD3) by instrumental analysis including BET analysis, SEM, XPS, SEM-EDS and FT-IR. As a result, the proper regeneration-temperature for deactivated photocatalyst to be regenerated several times (more than 3 times), was suggested below 200℃. Such temperature of deactivated photocatalystregeneration was almost consistent to the one, according to BET analysis, at which tiny nano-pores blocked by adsorbed ethanol-oxidative and degraded intermediates (AEODI), were regenerated to be reopened through almost complete mineralization of AEODI. In particular, the results of XPS analysis indicated an incurrence of insignificant deactivation of photocatalysis upon 1^st run of UV/photocatalytic reactor (A or C) of the previous investigation. In addition, the results of XPS analysis were consistent with the experimental results of the previous investigation in that 1) deactivation of photocatalyst incurred during 2^nd run of the UV/photocatalytic reactor (A or C) resulted in decreased removal efficiency, by ca. 5% and 5%, of ethanol and hydrogen sulfide, respectively, compared with its 1^st run; 2) there was insignificant difference between the removal efficiencies of its 2^nd run and 3^rd run. Furthermore, the removal efficiencies of ethanol and hydrogen sulfide for hypothetical 4^th run of photocatalytic reactor in the previous investigation, using AD3, were expected to decrease, compared with its 3^rd run, by much more than those for 2^nd run in the previous investigation did, compared with its 1^st run.

김금순 ( Keum Soon Kim ),이명선 ( Myung Sun Yi ),방경숙 ( Kyung Sook Bang ),조용애 ( Young Ae Cho ),이정림 ( Jung Lim Lee ),이은 ( Eun Lee ) 서울대학교 간호과학연구소 2013 간호학의 지평 Vol.10 No.2

본 연구는 불쾌감 이론을 기반으로 생리적 요인(폐암 병기와 활동상태), 심리적 요인(불안과 우울), 상황적 요인(사회적 지지)과 증상경험 및 기능적 상태와의 관계를 파악하여 폐암 환자의 증상경험을 관리하는 간호실무에 적용하고자 시행되었다. 본 연구에서 대상자가 지각하는 증상경험은 일반 암 관련 증상과 폐암 특이 증상 점수를 합친 것으로 평균 12.62점이었다. 이는 일반 암 관련 증상을 살펴 본 Baek10)의 27.7점과 Lee와 Kim19)의 23.1점과 비교 시 낮았으며, 일반 암 관련 증상과 폐암 특이 증상 점수를 함께 측정한 Lee3)의 평균 17.15점보다 낮은 점수였다. 이러한 차이는 연령과 현재 치료에 의한 것으로 생각된다. 본 연구의 대상자는 70세 미만으로 60대가 50.5%를 차지한 반면에 Baek10)의 연구에서는 60대 이상이 66.5%인 것을 보면 연령이 증가할수록 증상이 심하다는 연구 결과7)를 지지하고 있다. 특히, 폐암은 연령이 증가할수록 발생이 높아져 70대에서의 발생이 34.5%로 가장 높은 것을 볼 때 증상관리에 대한 요구가 높음을 알 수 있다.2) 또한 본 연구에서는 현재 치료를 받고 있는 대상자가 38.6%로 Lee3)의 43.9%와 전체 대상자가 항암화학요법을 받고 있는 Baek10)의 연구와 비교 시 낮았기에 증상경험이 낮은 것으로 생각된다. 또한 대상자가 지각하는 영양상태나 건강상태가 좋을수록 증상경험은 낮은 것을 발견하였다. 그러나 본 연구대상자들의 56.4%가 암을 진단받은 지 2년이 경과하였고, 38.6%가 현재 치료를 받고 있음에도 불구하고 영양상태가 나쁘다고 인지하는 경우는 3.0%였으며 또한 지난 한달 간 4 kg 이상의 체중감소가 있었던 경우도 2.0%에 불과하였다. 또한 대상자의 80.2%가 현재 건강상태를 보통 이상으로 지각하고 있었다. 따라서 추후에 대상자의 영양과 건강상태에 대한 지각이 증상에 미치는 영향을 규명할 필요가 있다고 생각된다. 생리적 요인인 폐암 병기, 활동상태와 증상경험 간의 관계를 살펴보면, 폐암 병기와 증상경험 간에는 유의한 상관관계를 보이지 않았으나 활동상태와 증상경험 간에는 유의한 중등도의 순상관관계를 보여 활동상태가 저하될수록 증상경험이 심한 것으로 나타났다. 폐암 환자에 있어서 병기는 치료의 방향을 결정하는데 중요한 변수이나 대상자가 경험하는 증상과는 유의한 관계를 보이지 않았고, 오히려 병기와 상관없이 현재 항암화학요법과 같은 치료 중에 있는 대상자의 증상경험이 더 심각한 것으로 나타났다.3,19) 그러나 본 연구에서는 항암화학요법을 받고 있는 대상자의 증상점수가 그렇지 않은 대상자보다 높았지만 유의한 차이는 아니었기에, 질병 관련 생리적 요인에 대한 추가적인 탐색이 필요하다고 사료된다. 본 연구는 외래를 방문하는 환자를 대상으로 하여 활동상태가 ECOG PS 0에서 2단계로 활동상태가 저하될수록 증상경험은 유의하게 높았고, 이는 선행연구의 결과를 뒷받침하고 있다.3,10,11) 심리적 요인인 불안, 우울과 증상경험 간의 관계를 살펴보면, 불안과 우울 모두 증상경험과 유의한 중등도의 순상관관계를 보여 불안, 우울과 같은 심리적 디스트레스가 높을수록 증상경험이 심하게 나타난다는 선행연구의 결과와 일치한다.20,21) Lee3)의 연구에서 비소세포폐암 환자들이 지각하는 불안과 우울과 같은 디스트레스는 증상경험에 직접적인 영향을 주며, 증상경험을 통해 삶의 질에 매우 부정적인 영향을 주는 요인으로 밝혀졌다. 따라서 NCCN (National Comprehensive Cancer Network)의 권고와 같이 암의 진행단계마다 대상자의 불안과 우울을 평가하여 필요시 적절한 도움을 제공해야 하며,22) 이때 환자의 내적 능력인 극복력의 개념을 도입하는 것은 Lee3)의 연구에서 입증하였듯이 유용한 간호접근이 될 수 있다고 생각한다. 상황적 요인인 사회적 지지와 증상경험 간에는 유의한 상관 관계가 나타나지 않았으며, 이는 사회적 지지와 증상 간에 유의한 직접적인 관계가 나타나지 않았던 선행연구와 일치하였다.3,23) 그러나 Lee3)의 연구에서 사회적 지지는 극복력을 매개로 디 스트레스에 영향을 줌으로써 증상부담에 영향을 미치는 것으로 밝혀졌다. 또한 본 연구의 대상자가 지각하는 사회적 지지를 살펴보면, 20점 만점에 가족지지는 평균 17.69점, 친구지지는 13.63점, 의료인지지는 10.26점으로, 의료인 지지가 가장 낮으며, 이는 선행연구의 결과와 유사하였다.3,10) 이는 직접간호제공자일 뿐 아니라 옹호자, 지지자로서의 간호사의 역할 수행에 대한 도전적인 결과라 할 수 있다. 따라서 간호사의 지지를 증진시킬 수 있는 방법들에 대한 적극적인 모색이 필요하며, 아울러 증상경험에 영향을 미치는 상황적 요인들에 대한 추가적인 파악이 필요하다고 사료된다. 증상경험과 증상경험의 결과, 즉 기능적 상태와의 관계를 살펴보면, 유의하게 높은 역상관관계를 보여 증상경험이 심할수록 기능적 상태는 저하됨을 보여주고 있다. 이는 다발성 증상군의 경증군은 중증군에 비해 기능이 더 좋았다는 Lee와 Park4)의 연구결과와 호흡곤란 증상이 심할수록 기능상태는 저하되었다는 Mohan 등13)의 연구결과와 일치하였다. 또한 부작용 증상을 심하게 호소할수록 기능적 상태가 저하되었다는 Baek10)의 연구결과를 뒷받침하고 있다. 본 연구에서 폐암 환자가 지각하는 증상경험에 영향을 미치는 요인은 심리적 요인(불안과 우울), 생리적 요인(활동상태), 상황적 요인(사회적 지지)의 순으로 나타났으며, 이러한 요인들은 증상경험의 57.8%를 설명하는 것으로 나타났다. 구체적으로 살펴보면, 우울에 의해 증상경험이 43.4% 설명되었으며, 우울과 불안에 의해서는 50.7%설명되었다. 이는 Lee3)의 연구에서 폐암 환자를 대상으로 불안과 우울로 측정한 디 스트레스에 의해 증상부담이 62.8% 설명되었다는 결과보다는 낮았지만, 두 연구결과 모두 불안과 우울이 증상경험에 미치는 영향이 매우 큼을 보여주고 있다. 또한 활동상태가 증상경험에 미치는 영향을 고려하여 활동상태가 매우 저하된 중증의 환자에서의 반복연구가 필요하다고 생각된다. 또한 간호사는 폐암 환자의 증상에 대한 주기적인 평가를 기반으로 체계적인 관리를 제공함으로써 기능상태를 증진시키고 나아가 삶의 질 향상을 도모하는데 주도적인 역할을 담당해야 한다. 폐암 환자가 지각하는 증상경험, 영향요인들과 증상경험 간의 관계, 증상경험과 기능적 상태 간의 관계를 종합해 볼 때, 불쾌감 이론은 폐암 환자의 증상경험을 설명하는데 적합함을 알 수 있었다. 폐암 환자의 증상경험을 적절히 관리하기 위해서는 반드시 불안과 우울과 같은 심리적 요인들에 대한 평가와 환자상태에 맞는 간호접근이 선행되어야 하며, 이러한 과정에 간호사가 적극적으로 개입함으로써 환자 지지자로서의 역할을 수행해야 한다. 또한 불쾌감 이론과 같은 중범위 이론의 간호실무 적용이 더욱 활성화된다면 이론과 실무의 차이를 줄이고 간호실무가 과학적인 배경을 가지고 더욱 발전될 수 있으리라 사료된다. Purpose: The purpose of this study was to investigate the relationships of activity status, anxiety, depression, social support, symptom experience, and functional status in patients with lung cancer based on the theory of unpleasant symptoms. Methods: The participants for this study were 101 lung cancer patients who visited the outpatient department for treatment or follow-up at one hospital in Seoul. Data were collected from January 1 to February 8, 2013 using self-reported questionnaires and clinical records. To measure variables, the functional scale and symptom scale of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30, EORTC QLQ-Lung Cancer 13, Eastern Cooperative Oncology Group Performance Status, Hospital Anxiety and Depression Scale, and Multidimensional Scale of Perceived Social Support were used in this study. The data were analyzed using SPSS 19.0 software for Windows. Results: The symptom experience showed more severity in patients with lower activity status, higher anxiety and depression. With lower activity status and social support, functional status was lower. When anxiety, depression, and symptom experience were higher, functional status was also lower. The significant factors predicting symptom experience were depression, anxiety, activity status, and social support, which explained 57.8% of the variance. Conclusion: These results suggest that psychological factors such as anxiety and depression had a negative influence on the symptom experience of lung cancer patients. Therefore, providing emotional support based on the patients` needs prior to providing symptom management could be a useful strategy for improving symptom experience and functional status.

DEVELOPMENT OF HIGH VALUE-ADDED TEXTILE PRODUCTS WITHIN THE GLOBALIZATION OF THE KOREAN WAVE

Mi Suk Lee,Kyung Hee Chung,Song Mi Lim,Qingqing Luo 글로벌지식마케팅경영학회 2015 Global Fashion Management Conference Vol.2015 No.06

Fresh attention is being paid to lifestyle brands offering differentiated contents and value such that the 21st century is now being called the age of global lifestyle. Recently national income has been increasing and a broad lifestyle culture has been established. Thus, brands with Scandinavian (Sweden, Denmark, or Norway), culture sensitivity, and design have deeply permeated the domestic market which has led to a domestic consumers' lifestyle trend (Chung& Park, 2004; Kwon, 2013; Magnus & Chrystin, 2003). In particular, such global lifestyle brands as Marimekko (Finland), CathKidston (UK), and Muji (Japan) have secured competitiveness in the global market as textile products which reflect its country's cultural identity (Lee& Park, 2014). Meanwhile, a new word, Hanban (韓版)which refers to Korean brands or products that were created from the Korean wave (韓流), which refers to Korean dramas or songs. Korean culture has been commercialized and grafted into various industries. In particular, a strong wind of Hanban in fashion cultural products not only has spread the Korean lifestyle to the world, but has enhanced its influence on related industries as well as fashion. Although certain major Korean companies launched lifestyle brands such as Jaju, Modern House, Butter, and Pum to help realize a Korean lifestyle brand business, most products sold in Korean lifestyle brands focus on overseas imported goods,so it is difficult to find Korean images on these products(Bang, 2004; Lee & Chung, 2013). The size of the lifestyle market is growing as a high value-added industry that can lead consumers' lifestyle trends, and there is a growing interest for Korean fashion cultural products. Therefore, the purpose of this study is to attempt to develop textile designs for Korean-made high value-added products with the improvement of Korean brand values. For study methodology, the status of lifestyle brands at home and abroad was examined and textile designs were developed for lifestyle brand B. For the development of the textile designs, demand required by brand B was researched and a textile design concept was established based on fashion and interior decoration trends. Then, a textile was designed using a motive that can effectively represent the identity of brand B and the Korean image. Adobe Photoshop 6.0 and Adobe Illustrator CC programs were used for the standardized textile design motif, pattern development, and colorway. The results were as follows. First, global lifestyle brands such as Marimekko, CathKidston, and Muji sell differentiated lifestyle products from other brands by applying motifs and colors which symbolize their country's and city's cultural image on textile products and displaying their own identity and peculiarity. On the other hand, Korean lifestyle brands such as Casamia, Hanssem, Kosney, and Art Box do not plan or produce their own design, but will import and sell foreign textile fabric or textile products with high recognition, or copy imported fabric. Thus, their textile design is unsatisfactory to express their own identity and satisfy consumers' needs. Second, as to the development direction required by brand B, a Korean lifestyle brand, the focus was to first, 'design American and European products using colors and techniques which reflect Korean image trends', Second, to create a 'design with Scandinavia's peculiar simplified line and sensitive color', and finally, to make a 'flower pattern design with good sustainable market feasibility'. Based on the direction and 2015 S/S color and textile trends, three concepts were established: Global Tribe, Bunny in the Wonderland, and Beyond Nature. Global Tribe is a folk paintin g(Minhwa) representing the Korean image well, and was reinterpreted in a modern sense. Bunny in the Wonderland is a modern Scandinavian style design using a rabbit, a symbol of brand B, as the main motif. Beyond Nature used a flower motif in various expression techniques and images. A textile design was developed by extracting from a folk painting, a rabbit, and a flower motif and standardizing a motif in watercolor, pen, and graphic techniques. It was digitalized by a scanner and a pattern was made via the steps of color adjustment and repetition. Three kinds of textile designs were developed according to three concepts and four kinds of colorways were made for each design. This study attempted to develop a textile design as Korean-made high value-added textile products. It is meaningful to suggest textile design with Korean cultural images and brand identity. Further study will focus on the development of fashion cultural products and DIY products to commercialize developed textile design.

Self-Assembling Peptides and Their Application in the Treatment of Diseases

Lee,,Trinh,,Yoo,,Shin,,Lee,,Kim,,Hwang,,Lim,,Ryou, MDPI AG 2019 INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES Vol.20 No.23

<P>Self-assembling peptides are biomedical materials with unique structures that are formed in response to various environmental conditions. Governed by their physicochemical characteristics, the peptides can form a variety of structures with greater reactivity than conventional non-biological materials. The structural divergence of self-assembling peptides allows for various functional possibilities; when assembled, they can be used as scaffolds for cell and tissue regeneration, and vehicles for drug delivery, conferring controlled release, stability, and targeting, and avoiding side effects of drugs. These peptides can also be used as drugs themselves. In this review, we describe the basic structure and characteristics of self-assembling peptides and the various factors that affect the formation of peptide-based structures. We also summarize the applications of self-assembling peptides in the treatment of various diseases, including cancer. Furthermore, the in-cell self-assembly of peptides, termed reverse self-assembly, is discussed as a novel paradigm for self-assembling peptide-based nanovehicles and nanomedicines.</P>

Biofilter Modeling for Waste Air Treatment : Comparisons of Inherent Characteristics of Biofilter Models

Lim, Kwang-Hee,Lee, Eun Ju 한국화학공학회 2003 Korean Journal of Chemical Engineering Vol.20 No.2

The types of biofilter modeling may be primarily classified in accordance with whethef a biofilm is differentiated from other phases in each model. It may be a secondary classification with regard to biofilter-modeling whether sorption volume and / or adsorption are adopted as reservoirs or not. Thirdly, biofilter models are classified as to whether adsorption is assumed to exist through gas phase and / or a biofilm. Among all the biofilter-models of previous investigators all model-components including gas phase, a biofilm, sorption volume and adsorption surface are considered only in the model of Lim. Since his model does not require a numerical solution to describe the concentration of organic pollutants in waste-ari-streams along the height of a biofilter even under unsteady-state conditions, it satisfies the condition of simplicity that is one of the important model requirements. In spite of its simplicity, Lim's model predictions are fairly good to fit Hodge and Devinny's experimental data.

Effect of Photoperiod, Temperature and True-leaf Stage in Bolting Rate of Chicory (Cichorium intybus L. var. sativus)

Lim,Jung-Dae,Seo,Jeong-Sik,Lee,Hyeon-Yong,Kim,Jong-Dai,Lee,Jin-Ha,Yu,Chang-Yeon 한국자원식물학회 2004 Plant Resources Vol.7 No.1

Root chicory (Cichorium intybus L. var. sativus) is potential alternative medicinal and sugar crop which accumulates a high amount of linear polyfructan, inulin in its roots. A problem in root production is that over-wintered stock plants often flower. Once the plant becomes reproductive, stem elongation and root growth slows and floral buds arise from every node, rendering the plants useless for propagation. The objectives of this research was to examine the effectiveness of manipulating environmental factors containing photoperiod, temperature and number of leaf states. The experiment was performed in growth chamber to create two photoperiods (8 h, and 16 h) with three temperature regimes (5℃/3℃, 10℃/8℃, and 15℃/13℃ day/night temperature) for a total of six treatments on three type of true-leaf stage of plant. Data of bolting rate, shoot and root length, shoot and fresh weight was invetigated in each treatments. This is the first report on changes in bolting rate and shoots and roots production during a whole growing season and differences in the effect of cold and photoperiod treatment depending on the true-leaf stage of plant.

Lim,Jung-Dae,Yang,Deok-Chun,Lee,Hyeon-Yong,Kim,Jong-Dai,Lee,Jin-Ha,Sung,Eun-Soo,Yu Chang-Yeon 한국자원식물학회 2004 Plant Resources Vol.7 No.1

The establishment of an efficient protocol for plant regeneration and micropropagation from leaf explant cultures of Chicory, Cichorium intybus L. var. sativus. is reported. Callus formation rate appeared 100% from explant in all growth regulators, but calli formed in the prensence of naphthaleneacetic acid (NAA) were appeared very compact and non-embryogenic state. The regenerated shoots were obtained from leaf explant cultures on solid MS medium containing different concentrations of cytokinins and auxin. The highest number of shoots (5.7) per explant and shoot growth (2.8cm) was obtained on MS medium containing 0.1 mg BAP L^-1 and 0.1 mg NAA L^-1. Indole acetic acid was the most suitable auxin for root formation among three auxins tested. 2,4-D had no effect on shoot and root formation.
