In this study, we found out the relation between $FeCl_3$ recovering-concentration and stage number of extraction process for invar (Fe+Ni) etching process. In order to get the desired $FeCl_3$ recovering-concentration economically, we developed the simulation program for designing the optimal $FeCl_3$ extraction process. We got the key parameter for this simulation program through pilot scale experiments. The process simulation by the developed program could reduce the emission of waste etching solution as well as the treatment costs. In addition, the developed program could calculate the number of stage of the etchant recovering system and the process time to get the desired concentration of $FeCl_3$. This program was used to compute the optimal capacity of the etchant recovering system and applied to the optimization of the stage of the etchant recovering system in real IT industry.

Purpose: The purpose of this study was to explore the recovering process of men who had abused alcohol and has lived in a therapeutic community. Methods: Individual in-depth interviews were used to collect data from 10 of these men who has lived in the therapeutic community for more than one year. Qualitative data from field notes and transcribed notes were analyzed using the grounded theory methodology developed by Strauss and Corbin. Results: The core category about the recovering process of the men who had abused alcohol and are now in the therapeutic community was identified as "reconstructing a broken life". The recovering process of these men in the therapeutic community consisted of four phases; 'self-awareness stage', 'unfreezing stage', 'readjustment stage', and 'challenging stage'. Conclusion: In this study "reconstructing a broken life", as the core category vividly showed joys and sorrows of men who had abused alcohol and has lived in the recovering process of managing the yoke of life-long disease. In this process of recovery from alcoholic dependence the men gradually adjusted themselves to their given condition. Also they gained coping strategies to care for, and protect themselves. Therefore health care providers can establish supportive programs in the clinical field to empower these men by reflecting their proactive coping strategies.

인과적 메시지 로깅은 정상수행시 낙관적 메시지 로깅의 장점을 가지고, 회복시 비관적 메시지 로깅의 장점을 가지고 있다. 본 논문에서는 회복 프로세스들간의 비동기성을 향상시키기 위한 인과적 메시지 로깅에 기반한 새로운 회복 알고리즘을 제안하고자 한다. 기존의 인과적 메시지 로깅 기반 회복 알고리즘들은 살아있는 프로세스들의 수행을 대기시키거나, 회복 프로세스들간의 높은 동기성을 요구한다. 본 논문에서 제안하는 회복 알고리즘은 각 회복 프로세스가 자신의 회복만을 책임지게 함으로써, 여러 개의 프로세스들이 동시적으로 고장이 발생하더라도 회복시 살아있는 프로세스들의 수행을 대기시키지 않고, 회복 프로세스들 중 하나의 회복 프로세스에게만 과부하가 발생하지 않도록 한다. 또한, 제안하는 알고리즘은 각 회복 프로세스의 회복 과정이 다른 회복 프로세스의 연속적인 고장들에 의해 지연되지 않도록 한다. 본 논문에서는 제안하는 회복 알고리즘의 정당성을 증명하고, 시뮬레이션을 통해서 제안하는 회복 알고리즘이 기존 회복 알고리즘에 비해 고장난 프로세스의 평균회복시간을 단축시킨다는 것을 보여준다.Abstract Causal message logging has the advantages of optimistic message logging during failure-free execution and pessimistic message logging during recovery. In this paper, we present a new recovery algorithm based on causal message logging for improving asynchrony among recovering processes. Existing recovery algorithms based on causal message logging block the execution of live processes or require high synchronization among recovering processes. As each recovering process is responsible for only its recovery in our algorithm, the algorithm avoids blocking the execution of live processes during recovery even in concurrently multiple failures and overloading only one among recovering processes. Moreover, it allows the recovery of each recovering process not to be delayed by the continuous failures of other recovering processes. We prove the correctness of our recovery algorithm, and our simulation results show that our algorithm reduces the average recovery time of a failed process compared with the existing recovery algorithms.

Despite the importance of the marital treatment in the recovery process of alcohol dependency, the domestic situation lacks the programs for recovering alcoholic couples. It is very hard to find any program for couples with an alcoholic in recovery. Most of the related researches only deal with hospitalized patients and their families due to their limitations in contact with appropriate subjects. This imposes a limit in their expert and validity. This research finds its aim in investigating the needs of recovering alcoholic couples and of clinical professionals, and providing basic data for the development of program for recovering alcoholic couples. This research was studied with 20 recovering alcoholic couples with a mean duration of 3.9 years of sobriety and 10 clinical professionals with a mean duration of 7.5 years of alcohol-abuse counseling experience. As a result, it appeared that a marital program that covers communication skills, sex, domestic violence, financial problems and original family issues in relation with codependency would be appropriate; the program would also involve issues about relapse.

The purpose of this study was to develop the entity theory on the recovering process from gambling addiction. This study focused on "What is the process of getting out of the pit of gambling addiction?" based on grounded theory methodology suggested by Strauss and Corbin(1990). The subjects of this study were 7 male gambling addicts living in Jeonbuk area. As the result of this study, a total of 97 concepts were drawn, which were classified into 28 subcategories and 16 superordinate categories. The results of analyzing the categories by paradigm showed that in the process of overcoming gambling addiction, the casual condition was 'Being cut off money; 'Losing the will', and the contextual condition corresponding to this phenomenon was 'Shame', 'Repent', and 'Wanting to die'. The core phenomenon was 'Giving up the dream of hitting the jackpot'. The intervening condition to boost this core phenomenon was 'Being helped by friends', 'Being supported by the police', 'Being led by the family', and 'Showing the willpower'. The action/interaction strategies were identified as 'Cutting off the flow of funds', 'Overcoming the temptation of gambling', and 'Diverting attention to other things', ending up 'Being conscious of family', 'Growing up', and 'Being free'. The core concept in the process of overcoming the gambling addiction was revealed as 'Being free by giving up the dream of hitting the jackpot'. The process of getting over the gambling addiction was 'The dream of hitting the jackpot being shattered', 'Giving up the dream of hitting the jackpot', 'Getting out of it', and 'Being free'. The study participants were classified into four types; 'Challenging type', 'Enjoying type', 'Showing off type', and 'Obsessive type'. This study was expected to have significance in establishing the first theory in Korea on the recovering process of gambling addict.

This paper is concerned with a computational method for recovering a crack shape of steam generator tubes of nuclear plants. Problems on the shape identification are discussed arising in the characterization of a structural defect in a conductor using data of eddy current inspection. A surface defect on the generator tube ran be detected as a probe impedance trajectory by scanning a pancake type coil. First, a mathematical model of the inspection process is derived from the Maxwell's equation. Second, the input and output relation is given by the approximate model by virtue of the hybrid use of the finite element and boundary element method. In that model, the crack shape is characterized by the unknown coefficients of the B-spline function which approximates the crack shape geometry. Finally, a parameter estimation technique is proposed for recovering the crack shape using data from the probe coil. The computational experiments were successfully tested with the laboratory data.

In this paper, we propose a new algorithm for recovering the broken letters of relics into an original form by using Z-map and image processing. The letters of relics may have been broken by a lot of rubbed copy and a long time and tide. They need to be restored. But the manual reconstruction is a very tedious and laborious task. Thus, it is necessary to automate the restoration process. This paper presents a realistic algorithm with an application to Tripitaka Koreana by using Z-map and morphological filter.

The purpose of this study is to examine the recovering gambling addicts' overcoming process on their hardships of life which hamper their recovery. For this study, we had one to one depth interview with 10 participants who had overcome their hardships of life after stopping gambling. The data gathered from the interviews were analysed following the grounded theory process suggested by Strauss and Corbin. As a result, 131 concepts were constructed, and they were classified into 32 subcategories and 14 category. We presented "overcoming of the hardships of life through the acceptance of reality and re-determination" as a core subject which connects the whole concepts. Based on the research outcomes, we proposed some policy and practice intervention methods such as economic self-support program, social security service, and triangle support system by counselor-family-peer recovering addicts.
