Purpose: This study was designed to identify the factors affecting the nurses' experience of non-reporting adverse incidents in hospital. Methods: This study is a cross-sectional, descriptive survey design and nonrandom, convenience sampling. Study subjects were 392 clinical nurses, who have agreed to be the subject of this research. The measuring instrument of attitudes toward incident reporting was developed by the authors. The questionnaire which consisted of 17 items about worry about appraisal, the belief in improvement, the intention of reporting, and knowledge was measured by 5-point Likert-type scale. The estimate of internal consistency was alpha =.84. Analysis of data was done with use of mean, t-test, ANOVA, logistic regression with SPSS program. Results: Clinical nurses had experience of reporting incident (51.3%), non-reporting incident (76.5%). Statistically, significant differences were found between experiences group and non experience group in intention on reporting, belief on improvement, and worry about appraisal. Logistic regression analysis showed that the significant predictors were caused by report no-fault cases, belief on improvement, worry about appraisal. Conclusion: The result also indicated that, to improve the incident reporting and risk management, it might be necessary to give a belief that it results on improvement and remove concern about punishment through construction of no-blame system.

Purpose Customer Loyalty is the most important factor of customer relationship management (CRM). Especially in retailing industry, where customers have many options of where to spend their money. Classifying loyal customers through customers' data can help retailing companies build more efficient marketing strategies and gain competitive advantages. This study aims to construct classification models of distinguishing the loyal customers within a Korean retailing company using data mining techniques with R language. Design/methodology/approach In order to classify retailing customers, we used combination of support vector machines (SVMs) and other classification algorithms of machine learning (ML) with the support of recursive feature elimination (RFE). In particular, we first clean the dataset to remove outlier and impute the missing value. Then we used a RFE framework for electing most significant predictors. Finally, we construct models with classification algorithms, tune the best parameters and compare the performances among them. Findings The results reveal that ML classification techniques can work well with CRM data in Korean retailing industry. Moreover, customer loyalty is impacted by not only unique factor such as net promoter score but also other purchase habits such as expensive goods preferring or multi-branch visiting and so on. We also prove that with retailing customer's dataset the model constructed by SVMs algorithm has given better performance than others. We expect that the models in this study can be used by other retailing companies to classify their customers, then they can focus on giving services to these potential vip group. We also hope that the results of this ML algorithm using R language could be useful to other researchers for selecting appropriate ML algorithms.

Background: Korea is considered to have an integrative health system where both western medicine and Korean (traditional) medicine are officially recognized and provided. Although Korean medicine has been covered by National Health Insurance over 20 years, equity in the utilization of Korean medical care has rarely been examined. Methods: We examined medical care utilization and expenditure of outpatient Korean medicine using panel fixed effects model to remove selection bias. Then we compared it with pooled ordinary least square (OLS) model. This study used Korea Health Panel data, which provides accurate information on out-of-pocket health care payment, including non-covered medical services. Results: Principal findings indicate that the frequency of the utilization of Korean medicine is related with unobservable individual choices different from western medicine, so the panel fixed effect model is appropriate. But pooled OLS model is better fitted for the expenditure of Korean medicine, after controlling for western medical care expenditure. After adjusting for the selection bias, socioeconomic status (income, education) was significantly associated with the expenditure of Korean medicine, but not with the frequency of the utilization of Korean medicine. Conclusion: This study shows that expenditure of Korean medicine utilization is inequitable across socioeconomic groups, which implies that health insurance coverage of Korean medicine is not sufficient.

Objective : To evaluate the effect of Oriental Medical Treatment on a patient with Hypoxic Ischemic Encephalopathy followed by Cardiopulmonary Resuscitation Method : We applied various methodology of Oriental Medical Treatment including Acupuncture, Electroacupuncture, Physical treatment, Herbal Medicine, Moxibustion treatment and Western medication as well. Result: Herbal medicine was applied on the basis of the patient's history. We applied formular to remove phelgm as a pathogenic factor after Hypoxic Ischemic Encephalopathy. At the same time, considering the patient spent more than a month in ICU lacking appropriate nutrition, we used formuli on the basis of 'Deficiency of Spleen' focusing to vitalize the function of digestive system. As the condition of the patient changed, we also adapted formular accordingly. We prescribed Herbal medication to strengthen Yin and Yang equally as she got hospitalized for long time. Also we applied Acupuncture treatment and Moxibustion treatment to control Qi flow. The general condition of the patient got better with successful removal of Foley catheter and elevated Glasgow Coma scale. We used Electroacupuncture, Physical treatment and Western medication at the same to get maximized effect on relaxing the contracted muscle. According to the Modified Ashworth Scale (MAS), we have some changes in muscle spasticity but later, the effect was not that significant. Conclusion : We had a patient with Hypoxic Ischemic Encephalopathy followed by Cardiopulmonary Resuscitation. In the management of Hypoxic Ischemic Encephalopathy, Conservative treatments are the mainstream but there are not many alternatives. Therefore, We suggest that Oriental medical approach may contribute to the management of Hypoxic Ischemic Encephalopathy.

2007년 6월 29일, 중국은 전국인민대표대회 상무위원회 제28차 회의에서 노동계약법을 통과시켰다. 동 법규는 2008년 1월 1일부터 시행된다. 새로운 노동제도는 중국 대내 외적으로 큰 영향을 미칠 것으로 전망되고 있다. 중국의 새로운 노동제도는 중국 내에서 활동하고 있는 기업들뿐만 아니라 세계 경제에도 직접적인 영향을 미칠 수 있다. 이미 중국내에서 활동하고 있는 기업들은 노동계약법의 본격 시행에 대비한 대응 방안 마련에 부심하고 있다. 중국 정부는 노동환경 개선의 필요성 때문에 노동계약법을 제정했으나, 이미 기존의 노동법 하에서 활동해온 기업들은 당분간 새로운 제도에 대한 적응에 적잖은 어려움을 겪을 것으로 예상되고 있다. 이번 중국의 신노동계약법은 기존 근로계약의 문제점을 개선하고 노사관계를 규범화하여 노동자들의 권익을 보호하기 위한 기본 지침임을 강조하고 있다. 그러므로 근로계약법을 전체 사회 관계를 재조정하는 법률 규범으로 보고, 중국 정무의 집행 의지와 적절한 실행조치를 시험하는 동시에, 기업이 인력자원과 노사관계관리가 장기적 발전에 도움이 된다는 점을 인식하고 일정한 사회책임의식을 갖도록 요구하고 있다. 이에 따라 노동계약법 실행은 노동비용 및 기준의 상승, 기업의 인력자원관리에 대한 자주성 침해, 노사관계의 경직화과 같은 문제점을 외자기업들은 지적하고 있지만, 또 한편으로는 이번 법안의 입법 성공에 대해 노동계약법이 근로조건 개선과 노사관계의 조화 발전을 그 목표로 한다는 데에는 동의를 표하고 있다. 이러한 상황 하에서 노동계약법이 본격 시행될 경우 인건비 상승, 노무관리 부담 증가가 예상됨에 따라 인력 의존도를 낮추는 방향으로 경영체제를 정비하고 신노동계약법 시행에 대비한 직원 채용 퇴직제도, 급여시스템 등 제반 노무관리 시스템의 재정비가 요구된다. 예를 들어, 고용 인력을 최소화하는 경영체제의 도입, 장기고용 상황에 대응하는 인사노무관리체제의 정비, 공회와의 협력적 관계 구축, 노동쟁의 리스크 관리 대책 등을 수립할 필요가 있을 것이다.

본 논문에서는 한국의 전통 돌담을 생성하는 프랙탈을 이용한 절차적 모델링 알고리즘을 제시한다. 각 단계의 삼각형 메쉬를 세분하여 다음 단계의 메쉬를 얻는 것이 알고리즘의 주요 내용이다. 메쉬의 세분화 과정은 원하는 단계까지 재귀적으로 적용된다. 삼각형의 각 변에서 세 점을 무작위로 선택하여 네 작은 삼각형으로 나눈 후 각 정점이 법벡터 방향으로 조금씩 이동하면서 돌담의 울퉁불퉁한 모양을 만들어낸다. 매 단계마다 세분화한 메쉬에서 모양에 변화를 주지 않는 평평한 정점을 제거한다. 평평한 정도는 이산 곡률로 측정한다. 제거된 정점 주변의 점들로부터 새로운 삼각형들을 만들어 삼각형 메쉬를 완성한다.

Both raw wastewater and effluent from a rubber products manufacturing factory were found to be toxic to Daphnia magna though the effluent satisfied current water quality standards. Thus, in order to reduce toxicity, advanced oxidation processes (AOPs) such as gamma-ray (${\gamma}-ray$) treatment and ozonation ($O_3$) were applied. A combined ${\gamma}-rays/O_3$ treatment at 20 kGy after coagulation significantly reduced toxicity of raw wastewater, changing 48-h toxic unit (TU) value from 201.21 to 23.92. However, toxicity of treated water was higher than that of effluent (TU = 12.15). This shows limitation of gamma-ray treatment to remove toxicity of raw wastewater. In case of effluent, the combined ${\gamma}-rays/O_3$ treatment at 20 kGy efficiently decomposed toxic compounds down to non toxic level. This work strongly supports the necessity of toxicity reduction evaluation as well as toxicity-based effluent management.

추락, 감전, 전도, 충돌, 화재, 신체절단 등 건설현장에서 발생하는 재해는 다양하다. 그 중에서 가장 많이 발생하는 재해는 추락이다. 그러므로 건설현장에서 건설재해를 줄이기 위한 첫 번째 단계는 추락재해를 줄이는 것이라고 할 수 있다. 이미 추락재해 감소를 위한 많은 연구가 이루어지고 있지만, 최근 추락재해의 증가 추세를 볼 때 이러한 연구는 구체적이지 못하다고 할 수 있다. 그러므로 본 연구에서는 추락재해 감소방안의 방향을 구체적으로 제시하고자 최근 07년 1월부터 08년 6월까지의 건설현장 추락재해의 원인들을 파악하였다. 이를 바탕으로 추락재해의 핵심요인을 파악하였으며 이러한 접근방법을 통하여 파악된 핵심요인을 집중적으로 관리함으로써 추락재해를 줄일 수 있을 것으로 예상된다. 나아가 전체 건설재해의 감소에 기여할 수 있을 것으로 예상된다.
