Thriving at work is defined as the individual’s experience of vitality and learning, which means that a team member feels vitality and confidence in their work and feels that they are growing by themselves. This study examines the effect of thriving at work, which is the positive psychological state of the airline crew, on the task performance and the effect of leader-member exchange as moderating variables. The results show that the thriving of airline crew has a positive (+) effect on the task performance, and the leader-member exchange strengthens this effect as a moderating variable. The result of this study provides practical implications that the service companies can expect performance improvement by helping the employees to have a balance of vitality and sense of learning(thriving), and creating a favorable atmosphere for leader and member. Key words: thriving at work, task performance, leader-member exchange, airline crew 번영감은 활력감과 학습감이 결합된 개념으로서 구성원이 업무수행에 있어 활력과 자신감을느끼고 일을 통해 스스로 성장하고 있다고 느끼는 상태를 의미한다. 본 연구는 긍정적 심리상태로서의 번영감이 서비스 종사자의 업무성과에 어떤 영향을 미치는지 파악하고 분석하는데 목적이 있으며 상사-부하 간의 지지와 상호작용이 번영감과 업무성과와의 관계에 어떤 영향을 미치는지 밝히는데 의의가 있다. 본 연구는 항공사 승무원들을 대상으로 번영감이 업무성과에 어떠한 영향을 미치는지, 그리고 상사 부하 간 교환관계가 조절 변수로서 어떤 효과를 갖는지를 실증 분석하였다. 연구결과 항공사 승무원의 번영감은 기업의 업무성과에 유의한 정(+)의 관계가 있는 것으로 나타났고, 상사- 부하 간 교환관계는 조절변수로서 이러한 효과를 강화하는 것으로 나타났다. 본 연구의 결과는 서비스 기업들이 직원들이 번영감의 두 요소인 활력감과 학습감을 균형있게 가질 수 있도록 지원하고 상사와 부하의 관계가 우호적인 분위기를 조성함으로써 성과향상을기대할 수 있다는 점에서 실무적 시사점을 제공한다. 키워드: 번영감, 업무성과, 상사-부하 간 교환관계, 항공사 승무원

Paper-mulberry is the main raw material used to manufacture traditional Korean paper. About 20 workshops across Korea inherited the traditional method of Korean paper. How- ever, the common name for the paper-mulberry tree varies based on the region. Although an attempt at classification occurred using the dendrologic method, erroneous identifica- tion by researchers due to a variation in leaves was reported, and it was not possible to identify flowers or fruits. The precise scientific name is given via molecular phylogenetic analysis through gene sequencing of the paper-mulberry to solve this problem, and the effect on the pulp paper was investigated according to the morphological characteristics of the paper-mulberry bast fiber. In this study, paper-mulberry used in the manufacture of Korean paper were classified into two scientific names through taxonomic analysis: hybrid (B. kazinoki x B. papyrifera) and B. kazinoki. The hybrid has a relatively long fiber length, showing superior strength characteristics,B. kazinoki, has a relatively thick fiber width and cell thickness, thus rendering a bulky and highly absorbent paper. The morphological characteristics of bast fibers are different according to molecular phylogenetic classifica- tion, and the results of this study provide an opportunity to select the quality of paper in accordance with the intention of the consumer. .

고인희,정혜영,박주현,정서린,조아현 한국문화재보존과학회 2015 보존과학회지 Vol.31 No.4

본 연구에서는 천연 안료 중 남동광(Azurite)으로 제조된 청색계열 안료 입도의 단계별 분포특성을 파악하고자국내 ․ 외 청색계열 안료 57종을 선정, Malvern사의 Mastersizer2000을 이용하여 입도분석을 실시하였다. 실험 결과, 국내 ․ 외에서 시판되고 있는 청색 안료 일부를 제외하고는 비교적 단계별 입도 분리가 잘 되어 있으며, 안료의 입도가작아질수록 Span 값은 증가하고 입도 분포 범위는 넓어지는 특징을 확인할 수 있었다. Friedman and Sanders가 제안한Grain size를 기준으로 보면 대부분의 안료는 주로 모래와 실트영역에 해당하였으며 B-100은 72.2%가 점토영역에 해당되었고 A-14는 자갈에 해당하는 영역이 2.5%를 차지하였다. 나아가 동일 성분의 안료라 할지라도 입자 크기에 따라안료의 발색특성이 다르며 흡유량, 비중, 작업성 등 중요물성에 밀접한 영향을 미친다. 이에 대한 추가적 실험이 필요하며물리적 특성과 입도분포 특징에 대한 정보는 천연 안료의 취급을 위한 기초자료로 활용될 수 있을 것이다 . This study were conducted the particle-size analysis on 57 blue pigments to understand the step distribution characteristics of blue pigments made out of Azurite by using Malvern’s Mastersizer 2000. As the result, most of the conventional blue pigments in Korea, Japan, and Chinese showed good granularity step separation except for few, and the smaller the particle, the more the Span value increased and the wider the granularity distribution range. On the basis of Friedman and Sanders’s Grain size, most of the pigments were sand size to silt size. 72.2% of B-100 was clay size and 2.5% of A-14 was gravel size. Even the same components can differ by the grain size directly affecting the important property such as color formation, oil absorption, specific gravity, usability, etc. so the information about the granularity distribution would be used for basic data to deal with natural pigments.

고인희,정선화 한국문화재보존과학회 2018 보존과학회지 Vol.34 No.6

This study using a method different from those employed previously, the anatomical characteristics of paper-mulberry wood were confirmed by observing three different sections. In addition, the factors affecting the pulp and papermaking processes were analyzed in terms of morphological properties such as the fiber length and width, lumen width, and chemical composition of the paper-mulberry bast fiber. The anatomical characteristics of the paper-mulberry wood were a ring porous or semi-ring porous structure with the vessels showing solitary pore and radial array. The medullary ray of the tangential section showed 1-3 rows and common helical thickening. Consequently, the paper-mulberry wood has the same anatomical characteristics throughout. The morphological characteristics of the paper-mulberry bast fiberare a fiber length of 6.58 to 9.01 mm, fiber width of 15.85 to 27.80 μm, lumen width of 4.50 to 12.54 μm. The D sample of Gangwon was the most suitable for the pulp and papermaking processes, in terms of its derived morphological ratios. Comparing the chemical compositions, the C sample of Gyeongsang had a high holocellulose content (90%). Thus, the findings herein will aid in determining the quality of Korean paper post production. 본 연구는 닥나무의 삼단면 관찰을 통하여 공통된 해부학적 특성을 가지는지 확인하고 닥나무 인피섬유의 섬유장·폭, 내강폭과 같은 형태학적 특징과 화학적 특징을 통해 펄프, 제지공정에 영향을 미칠 수 있는 인자들을 분석하였다. 닥나무는 환공재, 반환공재이며 대도관이 고립관공으로 방사상배열이다. 접선단면 방사조직은 1~3열이고 나선비후가 관찰되어져 공통적으로 동일한 해부학적 특성이 나타났다. 인피섬유의 형태학적 특징으로는 섬유장 6.58~9.01 mm, 섬유폭 15.85~27.80 μm, 내강폭 4.50~12.54 μm로 나타났다. 펄프, 제지공정에 중요한 특성으로 여겨지는 runkel ratio, slenderness ratio 등을 고려했을 때 강원도 D시료가 가장 적합하였다. 인피섬유의 화학적 특성으로 경상도 C시료가 낮은 추출물 함량과 높은 셀룰로오스 함량을 가지는 것을 확인하였다. 섬유의 형태학, 화학적 특성은 한지 제조 후 품질을 결정하는 주요 인자의 기초자료로 활용될 것이다.

Indigo (Polygonum tinctorium L.) is a typical blue dye which had been used from ancient times. This study was going to shade the complicated traditional methods extracting indigo dye by the fermentation and producing as adsorbate on calcium hydroxide, which says so called as the ‘Indigo lime’. Accordingly we were going to make indigo through the hydrolysis of the hot water extractives of indigo leaves simply. During hot-water extraction, β-glucosidase which required hydrolysis of the linkage between indigo and glucose was not activated. To achieve this goal, indican was acid-hydrolyzed to glucose and indigo. The acetic acid, citric acid, hydrochloric acid, and sulfuric acid were used for the hydrolysis of hot water extractives. The hydrolysis conditions of extractives performed in water bath at 80℃ for 120 minutes and in an autoclave for 120 minutes. In the acid hydrolysis of extracted indican by hot water, the indican yields of acetic acid and hydrochloric acid hydrolysis were higher than sulfuric acid in water bath. Also, the indican yield of hydrochloric acid hydrolysis was better than sulfuric acid in autoclave. The hot water extracted indican was confirmed by HPLC analysis and its structure was confirmed by UV-Vis and FT-IR spectroscopy, compared with isolated indigo and commercial synthesized indigo. This improved extraction and hydrolysis methods can be replace the traditional indigo making method.

Since the 1980s, paper relics, including funeral odes, have been excavated during the process of urbanization, including land development and change of burial sites. However, these relics are extremely difficult to study because they are seriously damaged and may not be in their original shape. For safe conservation and restoration of such excavated paper relics, it is important to accurately characterize their fibers through appropriate scientific analyses. This study details optical analyses using stereoscopic microscopy, fluorescent microscopy, field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS), and Fourier-transform infrared spectroscopy (FT-IR), conducted on the paper fibers of seven funeral odes excavated from the burial site of Gwon Goeng (1494−1563). They were excavated from Gagoli, Pungcheonmyeon, and Andongsi in Gyeongsangbugdo, Korea, in March 2017. The investigation revealed that these materials are extensively damaged by pollution, hardening, and molds. Microscopic analysis showed that all the paper fibers of the funeral odes had a transparent membrane, suffered dislocation, and had cross-markings that are distinctive characteristics of paper mulberry bast fibers. SEM-EDS analysis of the foreign substances found between the fibers showed that these fibers comprise 14 different kinds of elements such as carbon, oxygen, calcium, sodium, and iron. The purpose of this study is to report on the kind of paper materials used in funeral odes during the middle Joseon period.
