Large corporations have the work and roles of employees clearly defined in accordance with their established internal structure whereas small and mid-sized firms may lack an official job specification or a written job description, causing ambiguity in the role of employees. In IT service companies, especially, there is a relatively large number of tasks requiring one person to play multiple roles and they are often highly dependent on few key players. In this reality where about 80% of the job seekers end up in SMEs, it is therefore necessary to look into how the turnover factors such as job strain and occupational burnout caused by the role ambiguity from extra work affect the turnover intentions of small and medium sized IT service firm employees. The outcome of this study is as follows. First, the relationship between job strain and turnover intention has been examined to find that a weak inverted U shaped relationship exists between role overload, which is a subset of job strain, and turnover intention. Second, the hypothesis based on the competing values framework has been tested that the fitness with organizational leadership and culture would moderate the relationship between job strain and turnover intention and it has been confirmed that the degree of relationship between role conflict and role ambiguity, the subsets of job strain, and turnover intention has changed. In conclusion, in order to discourage turnover intention, it is necessary to increase the fitness with the organization and leadership or generate a sufficient level of strain in case of an organization with low fitness.

This study analysed marital comflicts, related factors, and adjustments to those conflicts described by urban Korean women. The purpose was to discover directions for resolution that would enhance the helpfulness of volunteers or prfessionals working with women in counselling settings. The investigator interviewed 20 married women, all mothers and housewives living in Seoul, attending marriage encounter programs and the Lifeline telephone counselling service. An interview schedule using six open-ended questiona guided the data colleciton which took place between May 31 and December 29, 1988. Content analysis of the data revealed, in order of reported frequency, the following areas of conflict: relationships between husband wife, relationships with children, relationships between the wife and her mother-in-Law, unsatisfied sexual needs, the husband's extra marital relationships, lack of self actualization and finacial matters. Analysis of the data suggested the following factors were related to the conflicts: reasons for marriage, traditional views about marriage and divorce including to accept a marriage arranged by the parents, the husband's traditonal attitude toward the sex role of the wife, the husband's patriarchical authoritarianism, and his attitude toward the wife;s empolyment outside the home. The women thought these conflicts severely affected their relationships within the famaily, particularly with their children. Literature suggests links with such poor parent-child-family relationships and adolescent or young people's social problems. Volunteers or professionals working with married women in counselling situation need to be conscious of the possibility of these conflict during assessment, and direct their guidance toward such conflict resolution. The researcher makes several suggestions which include the need for the husband to give emotional supports to his wife, to recognize the worth of housework, to share the work of the home, to fine ways to enhance the wife's self-actualization and to ease dreary housework routines by prviding modern appliances.

Objective: This work aims to investigate the therapeutic regimen of brain metastatic cancers and the relationship between clinical features and prognosis. Methods: Clinical data of 184 patients with brain metastatic cancers were collected and analysed for the relationship between survival time and age, gender, primary diseases, quantity of brain metastatic foci, their position, extra cranial lesions, and therapeutic regimens. Results: The average age of onset was 59.1 years old. The median survival time (MST) was 15.0 months, and the patients with breast cancer as the primary disease had the longest survival time. Females had a longer survival time than males. Patients with meningeal metastasis had extremely short survival time. Those with less than 3 brain metastatic foci survived longer than patients with more than 3. The MST of patients receiving radiotherapy only and the patients receiving chemotherapy only were all 10.0 months while the MST of patients receiving combination therapy was 16.0 months. Multiple COX regression analysis demonstrated that gender, primary diseases, and quantity of brain metastatic foci were independent prognostic factors for brain metastatic cancers. Conclusions: Chemotherapy is as important as radiotherapy in the treatment of brain metastatic cancer. Combination therapy is the best treatment mode. Male gender, brain metastatic cancers originating in the gastrointestinal tract, more than 3 metastatic foci, and involvement of meninges indicate a worse prognosis.

Background Polydactyly of the foot is one of the most frequent anomalies of the limbs. However, most classification systems are based solely on morphology and tend to be inaccurate and less relevant to surgical methods and results. The purpose of this study is to present our new classification of polydactyly of the foot, which can serve as a predictor of treatment and prognosis. Methods To find a correlation between the various morphologic traits of polydactyly of the foot and the treatment plan and outcomes, we reviewed 532 cases of polydactyly of the foot in 431 patients treated in our hospital, expanding on our previous study that described polydactyly based on the importance of metatarsal bone status and varus deformity. The records of patients were evaluated and compared with previous studies at other centers. Results Unsatisfactory results were seen in 36 cases, which included 5 cases of incomplete separation due to syndactylism, 23 cases of axis deviation, and 8 cases of remnants of extradigit metatarsal bones. The locus of the polydactyly, or the digit which was involved, did not seem to affect the final postoperative outcomes in our study. Three factors-syndactylism, axis deviation, and metatarsal extension-are the major factors related to treatment strategy and prognosis. Therefore, we developed a new classification system using three characters (S, A, M) followed by three groups (0, 1, 2), to describe the complexity of polydactyly of the foot, such as $S_1A_2M_2$. Conclusions Our new classification could provide a communicable description to help determine the surgical plan and predict outcomes.

Objectives : Halitosis is a common human condition, exact pathophysiological mechanisms of which are unclear. This study, which investigates halitosis patients' characteristics and their related factors, was done with intent to establish a foundation for the Oriental Medical treatment of halitosis. Methods : 329 patients were surveyed by reviewing medical charts and questionnaires from the East-West Halitosis Clinic of Kyunghee Medical Center from May 1, 2001 to December 31, 2002. Sex, age, illness duration, coating on the tongue, postnasal drip, globus pharyngeus, indigestion, condition of feces, halimeter measurements and results of the salivary scans were analyzed. Results : The thick and yellowish coating on the tongue was not a major cause of halitosis in the patients studied. Among the halitosis patients, 21.6% complained of postnasal drip, 15.6% of globus pharyngeus, 37.4% of indigestion, and 23.8% of diarrhea or constipation, suggesting the possibility of extra-oral origin in oral malodor. Conclusions : This study suggests that, when treating halitosis patients, intra-oral causes of halitosis aside, Oriental Medical treatments such as solving qi-stasis(氣鬱), augmenting deficiency of the spleen qi(碑氣虛) and treating gastric fever(胃熱) constitute effective management for oral malodor patients.

The gold standard method for diagnosis of tuberculosis is the isolation of Mycobacterium tuberculosis through culture, but there is a probability of cross-contamination in simultaneous cultures of samples causing false-positives. This can result in delayed treatment of the underlying disease and drug side effects. In this paper, we reviewed studies on false-positive cultures of M. tuberculosis. Rate of occurrence, effective factors, and extent of false-positives were analyzed. Ways to identify and reduce the false-positives and management of them are critical for all laboratories. In most cases, false-positive is occurring in cases with only one positive culture but negative direct smear. The three most crucial factors in this regard are inappropriate technician function, contamination of reagents, and aerosol production. Thus, to reduce false-positives, good laboratory practice, as well as use of whole-genome sequencing or genotyping of all positive culture samples with a robust, extra pure method and rapid response, are essential for minimizing the rate of false-positives. Indeed, molecular approaches and epidemiological surveillance can provide a valuable tool besides culture to identify possible false positives.

스무딩(Smoothing)은 가변 비트율로 저장된 비디오 데이터를 고정 비트율로 변환하는 전송 계획이다. 이러한 스무딩 알고리즘들에는 CBA, MCBA, MVBA 알고리즘 등이 있다. 그러나 이 알고리즘들에서는 서버에서 제공할 수 있는 여분의 대역폭의 크기를 고려하지 않아서 서버에서 비디오 데이터를 보다 많은 클라이언트들에게 제공하는 것을 어렵게 할 수 있다. 본 논문에서는 제한된 네트워크 대역폭을 갖는 동영상 서버에서 보다 많은 클라이언트들에게 비디오 데이터를 제공할 수 있게 하기 위하여 전송률 감소량(증가량)이 최대(최소)로 하는 스무딩 알고리즘을 제안한다. 제안 알고리즘의 성능을 평가하기 위하여 여러 가지 평가 요소를 사용하였으며, 제안 알고리즘은 기존의 다른 알고리즘들과 비교하여 최대 클라이언트 서비스 개수, 평균 클라이언트 서비스 개수 등과 같은 평가 요소에서 우수함을 보였다.
