The cytologic samples of 26 ovarian cystic lesions from 25 women, aspirated under guide by trans-vaginal ultrasound, were evaluated for clinicopathologic correlation. Clinically 20 women were seeking medical assistance for infertility problems, and trans-vaginal cyst aspiration was done during follow-up of ovulation induction. Among them seven cases were histologically confirmed. Twenty cases of "benign cyst" in cytologic diagnosis were follicullar cyst and two cases of "endometriotic cyst" in cytology were histologically also proven in one case. One false positive diagnosis was given to corpus luteum cyst. It is emphasized that because the cysts are aspirated transvaginally and mature squamous epithelial cells occasionally could be mixed in the sample, attention should be given not to diagnose such cases as mature cystic teratoma. According to this study. ovarian aspiration cytology is useful in the management of cystic ovarian lesions, particularly in young women.

How to efficiently manage assembly blocks at shipyard has been a hot management issue in the shipbuilding Industry, because it has significantly influenced on the productivity of shipbuilding process. This paper introduces the real practice of assembly block operations management in Hyundai Heavy Industries (HHI) and the Ship Assembly Block Operations Optimization (SABOO) project that h3s been launched in HHI as an academy-and-industry collaborative project, aimed to diagnose problems, propose possible solutions, and develop a prototype system in order to search ways of improving the assembly block operations management. Through the field interviews, observations, and benchmarking studies, the SABOO project diagnosed the most rudimental and urgent problem and proposed possible solutions. In addition, the SABOO project developed the prototype system that embodied the visual function of monitoring the shipyard on a real-time and the Interactive block assignment function that utilized the assembly block assignment algorithm developed by the project. As a whole, the SABOO project tested the possibility and gained an insight in extending the functions of block transportation/stockyard management system.

As cultural Heritages are source of the national history and a life transition, their extinction is a fatal shock as result of cutoff the genealogy of the creative national spirit. So, we have necessarily to protect them, and to get the duty and the responsibility which the cultural inheritance hands over tnem to descendants with preserving and meaning safely at present time. In these days, the risk of fire in the Cultural Heritages building is increased because of rash changing environments from the indiscreet development of them. Accordingly, in order to get the original transmission of the Cultural Heritages, this paper involves being intensive the fire safety information of the Cultural Heritage in kyonggi-do province, analyzing their diagnoses, and studying a Fire Safety Prevention Management model to protect and to maintain them continuously. Therefore, it is to contribute from this approach to collecting fire safety information, analyzing diagnostic problems in fire accidents, and to manage the prevention method for protecting and maintaining the Cultural Heritages.

In spite of considerable advances in water quality control measures within lake, many basic questions concerning an eutrophication still remains unanswered and it becomes obvious that an extensive limnological database is needed for the inter-comparison between bodies of water and for the assessment of the status of lake water quality. In order to diagnose the water environment and assess the changes of the water quality, Wangkung irrigation reservoir was investigated by a long-term monitoring program for the physical, chemical and biological water quality parameters. In addition, these data was used to determine the design elements of natural purification facilities.

In transformer fault diagnosis, dissolved gas analysis (DGA) is been widely employed for a long period and numerous methods have been innovated to interpret its results. Still in some cases it fails to identify the corresponding faults. Due to the limitation of training data and non-linearity, the estimation of key-gas ratio in the transformer oil becomes more complicated. This paper presents Intuitionistic Fuzzy expert System (IFS) to diagnose several faults in a transformer. This revised approach is well suitable to diagnosis the transformer faults and the corresponding action to be taken. The proposed method is applied to an independent data of different power transformers and various case studies of historic trends of transformer units. It has been proved to be a very advantageous tool for transformer diagnosis and upkeep planning. This method has been successfully used to identify the type of fault developing within a transformer even if there is conflict in the results of AI technique applied to DGA data.

Actinomycosis is an unusual granulomatous infection caused by gram-positive anaerobic bacteria called Actinomyces species(predominantly Actinomyces israelii), which is a common and normally nonpathogenic organism found in the nose and throat. The three major clinical presentations of actinomycosis include the cervico-facial(the most common, 55%), thoracic, and abdominopelvic region. Actinomycosis typically has a chronic, indolent course characterized by swelling and induration of the soft tissues and eventual spontaneous drainage through multiple sinus tracts. Actinomycosis is difficult to diagnose because of variable presentation mimicking neoplasm and fastidious nature of the organism in culture. We present a case of actinomycosis in the parotid tip area which was mistaken for a salivary tumor.

Stellate ganglion block (SGB) is a frequently used sympathetic block utilized to diagnose or treat various painful conditions of the cervical regions and the upper extremities. Additionally, RadioFrequency (RF) lesions of the stellate ganglion can be useful in managing sympathetically-maintained pain. Two patients were suffering from pain in the face, neck and the upper extremities were treated with stellate ganglion block. In spite of repeated blocks, the degree and duration of pain did not decrease. However, after performing radiofrequency thermocoagulation of the stellate ganglion under fluroscopy, followed by thermography on the process of treatment with RF stellate ganglion neurolysis, the patients' pain levels were alleviated after the RF lesions of stellate ganglion and the procedure also increased the temperature at the upper extremity on thermogarphy. Additionally, the patients did not complain of any remarkable complications following this procedure.
