Purpose: This study was to investigate the quality characteristics of wet noodle added with radish juice containing with pulp. Methods: Wet noodles were prepared with different amounts of radish juice (0%, 20%, 40%, 60%, 80%, 100%, w/w) instead of water. Results: As the amount of radish juice was increased, water absorption, volume increasing rate, and turbidity of soup were decreased. Lightness (L) values of uncooked wet noodles and cooked noodles were decreased with the addition of radish juice, while redness (a) and yellowness (b) values had no tendency of increasing or decreasing, regardless of the amount of radish juice. Moreover, lightness, redness, and yellowness values of uncooked noodles were higher than those of cooked noodles. The texture of cooked noodles showed significant differences in hardness and chewiness. It was increased as the amount of radish juice was increased. Their adhesiveness and springiness were lower than those of the control. Appearance, texture, and overall acceptability of sensory evaluation revealed that the noodle added with 80% of radish juice had the highest scores, although there were no differences among noodles added with different amounts of radish juice. Conclusion: In summary, the most desirable blending ratio of radish juice and water for the kneading of wet noodles was 80:20.

Purpose: Guided bone regeneration(GBR) has emerged as a treatment in the management of osseous defects associated with dental implants. But several studies have reported different degrees of success of guided bone regeneration, depending upon the type of barrier selected, presence or absence of an underlying graft material, types of graft material, feasibility of technique, and clinician's preference. The aim of the present study was to evaluate bone formation following dental implant placement with augmentation materials at dehiscence defects in dogs. Material and Methods: Standardized buccal dehiscence defects($3{\times}5\;mm$) were surgically 2 Mongrel dog's mandibles, each 8 SLA surface, 8 anodizing surface implants. Each buccal dehiscence defect received flap surgery only(no treatment, control), $Cytoflex^{(R)}$ membrane only, Resolut $XT^{(R)}$ membrane only, Resolut $XT^{(R)}+Osteon^{TM}$. Animals were sacrificed at 8 weeks postsurgery and block sections were harvested for histologic analysis. Resuts: All experimental group resulted in higher bone formation than control. Resolut $XT^{(R)}+Osteon^{TM}$ group resulted appeared highest defect resolution. There was no difference between SLA and anodizing surface, nonresorbable and resorbable membrane. Conclusion: GBR results in rapid and clinically relevant bone closure on dehiscence defects of the dental implants.

Among the operating limits of a heat pipe, the capillary limit is significantly affected by the characteristics of the wick, which is determined by the capillary performance. The major parameters for determining capillary performance are the maximum capillary pressure and the spreading characteristics that can be expected through the wick. A well-designed wick structure improves capillary performance and helps improve the stability of the heat pipe by enhancing the capillary limit. The capillary performance can be improved by forming a porous microstructure on the surface of the wick structure through surface modification techniques. In this study, a microstructure is formed on the surface of the wick by using a surface modification method (i.e., an electrochemical etching process). In the experiment, specimens are prepared using stainless-steel screen mesh wicks with various fabrication conditions. In addition, the spreading and capillary rise performances are observed with low-surface-tension fluid to quantify the capillary performance. In the experiments, the capillary performance, such as spreading characteristics, maximum capillary pressure, and capillary rise rate, improves in the specimens with microstructures formed through surface modification compared with the specimens without microstructures on the surface. The improved capillary performance can have a positive effect on the capillary limit of the heat pipe. It is believed that the surface microstructures can enhance the operational stability of heat pipes.

유방의 세침흡인 세포검사: 수기 액상세포검사법(Liqui-$PREP^{TM}$)과 고식적 도말법과의 비교

Fine needle aspiration (FNA) cytology of the breast is a useful method for diagnosing breast lesions. Yet making the definite diagnosis with performing FNA is limited by some problems, such as the low cellularity, the poor preservation and the obscuring background. Recent studies have found that liquid-based cytology solves such problems, but it is an expensive method and it is limited by the loss of the background information. The purpose of this study is to compare the Liqui-$PREP^{TM}$, a new manual liquid-based method of cytology, and the conventional smears for analyzing breast FNA cytology materials. A total of 31 randomized FNA specimens of breast were studied. In each case, both the conventional smears and the Liqui-$PREP^{TM}$ method were performed, and the smears were evaluated for cellularity, cellular preservation, the background, the cytologic features and the architectural arrangement. The cellularity and architectural arrangement were equal for both preparations. The Liqui-$PREP^{TM}$ specimens showed better cellular preservation, loss of the obscuring background, no overlapping of cells and a smaller area to screen compared with the conventional smears. Moreover, it has the potential advantages of being able to use the remaining specimens for immunohistochemical study and ploidy analysis, and it can reduce the costs for preparation compared with the other liquid-based methods of cytology. But some background information is lost in the Liqui-$PREP^{TM}$ specimens, the same as the other liquid-based methods of cytology. In conclusion, the Liqui-$PREP^{TM}$ and conventional smears showed good correlation, but they have their respective advantages and disadvantages. These results suggest that Liqui-$PREP^{TM}$ can contribute to making the accurate diagnosis with performing breast FNA cytology when it is used along with other methods.

In order to evaluate the mutagenic potential of Intralipidos produced by Greenmate cooperation. We performed Salmonella typhimurium reversion assay, chromosomal aberration test on chinese hamster ovarian cells and in vivo micronucleus assay using mouse bone marrow cells. In the reverse mutation test using Salmonella typhimurium TA98 and TA100, Intralipidos did not increase the number of revertant at any of the concentration tested in this study. Intralipidos did not increase the number of cells having structural or numberical chromosome aberration in cytogenetic test. In mouse micronucleus test, no significant increase were observed in the occurrence of micornucleated polychromatic erythrocytes in ICR male mice intraperitoneally administered with Intralipidos. These results indicate that Intralipidos has no genetic toxicity under these experimental conditions.

대순진리회 수행의 실제

정지윤 ( Ji Yun Jeong ) 한국신종교학회 2014 신종교연구 Vol.30 No.-

모든 종교에는 각기 궁극적으로 지향하거나 추구하는 종교적 이상과 목표가 있다. 이때 종교적인 수행(修行)은 해당 종교의 교인들이 그러한 이상과 목표를 실현하기 위해 실천하고 노력하는 일체의 행위들을 가리킨다. 수행이 이상세계를 향한 것이긴 하지만 그 출발은 현실과 밀착되어 있어서 현실적인 문제의 해결과 극복이 곧 수행이라 할 수 있다. 이러한 관점에서 필자는 대순진리회 수행의 유형적 방법으로 ‘훈회(訓誨)와 수칙(守則)’, ‘포덕(布德)과 교화(敎化)’를 간과할 수 없다고 생각한다. 현재 대순진리회는 일부 수도인들이 도법에 어긋나는 방법(거리포덕)을 취하여 사회적인 물의를 일으킴으로서 부정적인 이미지로 비춰지는 부분들이 있다. 이는 지난 46년 동안 급격한 양적 성장을 맞이한 대순진리회가 자체 정비 시간을 제대로 갖지 못했던 점과 수도인들이 대순진리회의 종교적 이상과 목적에 대한 이해 부족이란 점에서 실제적 수행법인 포덕에서 몇몇 불미스러운 일이 발생했다고 보인다. 그러므로 대순진리회의 수행에 관한 바른 이해는 그 종교의 이상과 목표에 관한 이해로부터 설명될 때 충실해질 수 있으며, 수행의 실제적 방법 역시 이러한 맥락에서 그 의미가 올바로 전달될 수 있을 것이다. 이를 위해 대순진리회가 궁극적으로 지향하는 ‘상생세계’와 이상적 인간으로서의 ‘도덕군자’의 의미와 가치를 살펴보았고, ‘상생세계’에 사는 ‘도덕군자’가 되기 위한 유형적 수행의 방법으로서 ‘훈회와 수칙’ 및 ‘포덕과 교화’에 주목하였다. 대순진리회의 유형적 수행이 추구하는 것은 결국 상생의 법리에 부합하는 생활화다. 이것은 곧 인간이 인존으로서의 ‘도덕군자’가 되는 것이고 후천선경으로서의 ‘상생세계’를 현실에 구현하는 것이다. 이러한 목적을 달성하기 위해 생활 속의 수행으로서 ‘훈회와 수칙’, 도덕 실천의 수행으로서 ‘포덕과 교화’를 바르게 실천할 필요가 있다. 본 논문은 대순진리의 이상과 목표에 관하여 다시 한번 되짚어보는 유의미한 작업이 될 것이며 여기서 다루는 수행의 실제적인 방법들 역시 바른 수행으로 다가서기 위한 초석이 될 수 있을 것이다. In every religion, there is a religious ideal and objective which it aims or pursues on an ultimate ground. Here, the religious practice designates the whole behaviors which practises and strives for realizing the ideal and objective. Yet, despite its directivity towards ideal world, the starting point of practice lies in reality. Practice is the thing which adheres to the real world while solving and overcoming the problems of reality. Thus, practice should not be isolated from, nor be disregarded irrespective of reality. With this outlook in mind, I propose that we can neither overlook the importance of commandments, ethical principles, nor propagation or edification. At present, Daesoonjinrihoe is shone a negative image in that some cultivators are active in propagating contrary to the ordinances of Do. On the one hand, it is because Daesoonjinrihoe could not secure enough time to reflect its own way to development due to the rapid quantitative growth of 46 years. On the other hand, lack of understanding of cultivators on the religious ideal and objective which Daesoonjinrihoe attempt to realize should be the other reason that they have committed disgraceful behaviors in the course of their propagation which should be an actual method of cultivation. Therefore, the right understanding on the practice of Daesoonjinrihoe can be obtained faithfully when it is explained from the ideal and objective of this religion, and the right meaning on the actual method of practice can be conveyed in that context. To achieve this goal, firstly, I have overviewed the meaning and value of the world and human being that Daesoonjinrihoe is ultimately aiming at. ‘The world of mutual beneficence’ as an ideal world, and ‘the moral man of its virtue’ as an ideal man provides for the normative justifiability for an actual practice. Secondly, I have focused on commandments, ethical principles as well as propagation and edification as an actual practice to become a ‘moral man of virtue’ living in ‘the world of mutual beneficence. In conclusion, the aim of practice in Daesoonjinrihoe is making Resolution of grievances to the mutual beneficence of all life and Repaying gratitude to the mutual beneficence of all life. By making these principles the basic way of life, man can become ‘moral with one’s own virtue’ and to realize ‘the world of mutual beneficence’ as an earthly paradise of the Later world in reality. To achieve these objectives, one has to perform a ‘propagation’, ‘edification’ as well as ‘commandments’ and ‘ethical principles’ as an actual practice in life. With this critical mind, this research is expected to be a meaningful work retracing its steps to reflect on the ideal and objective, and through this reflexion, it is also hoped that the actual method of practice can strengthen its basis to edge closer to the right practice in life.

코로나 19시대의 업무시간 외 업무관련 정보통신기술의 사용이 지식은폐에 미치는 영향

정지윤(Jeeyoon Jeong) 한국산학기술학회 2022 한국산학기술학회논문지 Vol.23 No.4

코로나 19 발발 이후, 업무시간 외 업무관련 정보통신기술(ICT)의 사용이 조직에 더욱 보편화되었다. 본 연구는 업무시간 외 업무관련 정보통신기술(ICT)의 사용이 정서적 고갈을 일으킴으로써, 그에 따른 지식은폐를 탐구하는 것을 목표로 한다. 자원보존이론에 기초하여, 본 연구는 업무시간 이후 업무관련 정보통신기술의 사용이 다른 개인 및 업무영역에 투자할 수 있는 자원의 가용성을 감소시킬 것이라고 제안한다. 특히, 본 연구는 업무시간 외 업무관련 정보통신기술의 사용이 스트레스적인 업무 부담으로 작용하여 자원의 고갈을 불러일으킴에 따라, 정서적 고갈을 초래할 것이라고 주장한다. 결과적으로, 감정적으로 고갈된 직원들은 더 지식은폐를 하게 될 것이다. 직원의 정서적 고갈은 업무시간 외 업무관련 정보통신기술의 사용과 지식은폐를 매개하는 요인으로 작용할 것이다. 국내 486명의 직장인들을 대상으로 종단연구를 실시한 결과, 업무시간 외 업무관련 정보통신기술의 사용과 지식은폐는 긍정적적인 관계가 있는 것으로 나타났다. 또한, 정서적 고갈은 업무시간 외 업무관련 정보통신기술의 사용과 지식은폐의 관계를 각각 매개하는 것으로 나타났다. 본 연구의 결과를 바탕으로 하여 이론적 및 실무적 시사점을 논하였다. Work-related use of information and communication technologies (ICTs) after working hours has become more pervasive in organizations since the outbreak of the COVID-19 pandemic. This study explores the detrimental impact of work-related use of information and communication technologies (ICTs) after work-hours on emotional exhaustion and knowledge hiding. In particular, this study proposes that repeated work-related use of information and communication technologies (ICTs) after work-hours would decrease the availability of resources to attend to work domains, according to the theory of conservation of resources. In particular, I identify work-related ICT usage as a stressful work demand that depletes resources as captured by employees" emotional exhaustion. In turn, emotionally exhausted employees engage more in knowledge hiding. Employees" emotional exhaustion is the mediator between work-related ICT usage after work-hours and knowledge hiding. I found support for a theoretical model using longitudinal field data from Korean employees. Theoretical and practical implications of these findings are also discussed in this study.

패턴 형상 및 입사각에 따른 Wire Grid Polarizer의 편광 특성 해석

정지윤(JiYun Jeong),조영태(YoungTae Cho),정윤교(Yoon-Gyo Jung) 한국기계가공학회 2014 한국기계가공학회지 Vol.13 No.3

With the development of technology, the display industry has been focusing on the development of new types of displays, such as bendable and wearable displays. However, the PVA/TAC polarizing film used in the manufacturing of a normal display is associated with low luminance and low efficiency. If the existing polarization film is replaced with a wire grid polarizer, it is possible to reduce the thickness significantly. Moreover enhanced brightness can also be expected. This study confirms the optical properties of the WGP through a simulation.
