  • Autophagy is a process tightly regulated by various autophagy-related proteins. It is generally classified into non-selective and selective autophagy. Whereas non-selective autophagy is triggered when the cell is under starvation, selective autophagy is involved in eliminating dysfunctional organelles, misfolded and/or ubiquitylated proteins, and intracellular pathogens. These components are recognized by autophagy receptors and delivered to phagophores. Several selective autophagy receptors have been identified and characterized. They usually have some common domains, such as motif, a specific cargo interacting (ubiquitin-dependent or ubiquitin-independent) domain. Recently, structural data of these autophagy receptors has been described, which provides an insight of their function in the selective autophagic process. In this review, we summarize the most up-to-date findings about the structure-function of autophagy receptors that regulates selective autophagy.

  • Lately each country tends to provide neutrality and ease of enforcement in order to settle disputes related to international trade through commercial arbitration. In order to expand the use of arbitration systems, most countries accept arbitration agreements as an effective tool agreed between parties that express their intent to settle disputes by the arbitration. It is applied equally to selective arbitration agreements and parties can select either arbitration or lawsuit to settle disputes based on the contract intent for selective arbitration agreements. However, China does not admit the effectiveness of selective arbitration agreements. Chinese courts regard selective arbitration agreements as not valid because the contract of a selective arbitration agreement between parties is not a definite expression to only use the arbitration and there is no exclusion of court jurisdiction. Therefore, the study attempts to consider effective conditions for selective arbitration agreements in the Chinese arbitration act and other relevant regulations, and also verifies the judgment by Chinese courts on relevant disputes. As a result, the study explores some problems and implications of Chinese selective arbitration agreements and suggests some precautions in case Korean companies pursue selective arbitration agreements with Chinese enterprises and investors.

  • The objectives of this study were to assess the current practices of implementing selective menus and to identify the perception of foodservice manager and customer on selective menus for hospital foodservice would be fulfilled. Two types of questionnaires for hospital foodservice managers as well as customers were developed. Questionnaires were distributed to managers of 8 hospital foodservice department and 317 customers of patient meal service, and 6 managers and 139 customers were responded. The data were analyzed using frequency and t-test. The results of this study can be summarized as follows : 1. In hospital foodservice operations, the selective menu pattern was first introduced by L hospital on June 1994 in Seoul and recently 8 hospitals were currently implementing selective menus. But using rate of selective menus by patients were relatively low(23.2%), ranging from 15% to 32%. 2. Customers' needs for selective menus were rated significantly higher in the group of patients(4.24/5) who chose the selective menus than their counterpart(3.88/5). 3. The main reason not choosing selective menus was identified by patients as 'not knowing the implementation of selective menus'(52.6%), inconvenient factors in using selective menus for customer were also identified as orders : 'lack of nutrition information on menu item'(38.6%), 'complexity in procedure'(29.8%), and 'lack of menu variety'(26.3%). However managers considered 'managerial burden' and 'limited human resource' as main obstacle to implement the selective menu pattern. 4. Customers indicated 'variety of menu', 'active public relations' as effective methods to enhance using rate of selective menus, however, foodservice manager indicated 'variety of menu'(50%), 'improvement of quality'(16.7%), and 'simplicity in procedure'(16.7%). Based on the results of this study, following recommendations have been suggested : Managers in patient meal service should recognize customer needs for implementing selective menus and pay more attention in implementing selective menus and activating this program. For more effective implementation of activating selective menu program, the foodservice department should establish action plan on 'active publicity work', 'simplicity in procedures', 'variety of menu' and 'improvement of quality'. Especially nutrition informations on meals should be provided for customers in order to elevate participation rate.

  • Most high efficiency silicon solar cells use a passivated selective emitter. It have been an important research subject for crystalline silicon solar cells for decades. It is being used in production for high efficiency solar cells. Most of the selective emitter process require expensive extra masking, etching steps, and a double diffusion process making selective emitters not cost effective. In this paper, we study method for single diffusion step selective emitter process as an alternative to not cost effective double diffusion process. Cost effective selective emitter that the efficiency should be increased significantly (mare than 0.2%) and that the process should simple, robust and cheap.

  • Objectives : The purpose of this study was to investigate the adult attachment style characteristics of mothers with selective mutism children and their relations to selective mutism. Methods :The subjects of this study were 15 mothers with selective mutism children who were diagnosed by DSM-IV criteria at psychiatry outpatient department of Kyungpook National University Hospital from March 1998 to February 2005. The controls of this study were 30 mothers with normal children who are in the second grade of elementary school in Daegu. We assessed the adult attachment style characteristics of these mothers by Revised Adult Attachment Scale, and Reciprocal Attachment Questionnaire-Korean version, self-report attachment style questionnaire. Results : 1) On the self-report attachment style questionnaire, it revealed that mothers with selective mutism children had both of the secure and the dismissing-avoidant types predominantly and the tendency that mothers with selective mutism children more commonly had dismissing-avoidant type than controls did. 2) On the comparison of attachment quality of mothers, although only the anxiety subscale difference was significant, it revealed that mothers with selective mutism children had generally lower score pattern in all of closeness, dependence and anxiety subscale than controls did. It was consistent with the consequence of self-report attachment style questionnaire in this study. Conclusion : This study showed that the distribution of adult attachment style of mothers with selective mutism children was different from those of controls. The dismissing-avoidant attachment style was predominant in mothers with selective mutism children. we suppose the possibility that the dismissing-avoidant attachment style of mothers with selective mutism children has relation with selective mutism.

  • Arbitration agreement is an agreement by the parties to submit to arbitration all or certain dispute which have arisen or which may arise between them. Arbitration agreement is an important factor to judge the existence of the mutual arbitration agreement and it should be the object of examination before anything else to judge the existence of the mutual arbitration agreement. Recently the Supreme Court seemed to make negative position about validity of selective arbitration agreement. However theoretically and scientifically selective arbitration agreement is a valid arbitration agreement. Examine selective arbitration agreement throughly according to the autonomy of the parties rules, wide jurisdiction rules of interpretation, principle of kompetenz-kompetenz, and moses cone presumption rule of interpretation, selective arbitration agreement is a valid arbitration agreement. Also analyze precedents in accordance with validity of selective from all angles which are voluntary agreement of the parties, agreement in writing, principle of private autonomy, comparative study of domestic and foreign precedents and mutual relation of arbitration and trial, selective arbitration agreement based on principle of private by the parties is considered a valid arbitration agreement. Courts should actively accept selective arbitration agreement as a valid arbitration agreement to make foreign companies prefer arbitration in Korea and in oder for arbitration to be widely used in disputes.

  • A method is proposed for the improvement of deposition reproducibility in the selective electrodeposition process using laser masking and DC voltage. Selective electrodeposition using laser masking and DC voltage can achieve a deposited layer with micro patterns. However, selective electrodeposition using laser masking and DC voltage have a critical problem: the lack of reproducibility in selective deposition. The reproducibility of selective electrodeposition can be improved by a new process that consists of laser masking, two-step electro-deposition, laser scribing, and ultrasonic cleaning. The experiments in this study show that the reproducibility of selective deposition can be successfully improved by the combination of two-step electrodeposition and laser scribing.

  • This paper presents the technology of selective emitter for high efficiency crystalline silicon solar cell. The effect of selective emitter is analyzed by using the simulation program for solar cell, PC1D. The selective emitter shows better spectral response in short wavelength regions compared to homogeneous emitter. Therefore, the efficiency of solar cell with selective emitter can be improved by changing the sheet resistance from 60 $\Omega/\square$ to 120 $\Omega/\square$. In addition, the power loss of solar cell can be minimized by optimizing width and gap of the finger electrodes on the selective emitter.
