Sensitive issues are both common and problematic for health care providers because sensitive issues may interfere with the future provider-client relationship and effective care. Most current training for providers focuses on a particular issue, but this is inadequate because many issues may be sensitive, and which issues will be sensitive is unpredictable. We argue that issues become sensitive when they activate one or more of three common triggers, fear, stigma, and taboo. A cycle of negative internal and interpersonal responses to the sensitive issue often leads to unresolved health issues for clients and stress and feelings of inadequacy for providers. We recommend integrated pre-service and in-service skill building to help individual health care providers respond appropriately to a wide variety of sensitive issues. We also identify specific policies and procedures to strengthen organizational support for caregivers so that providers can address these sensitive issues effectively with their clients.

This paper discusses several basic issues of the 'focus' phenomenon. One of them is the issue of the nature of focus, i.e., what constituent of the sentences gets focused. Another is the issue of to what aspect of meaning the focus contributes. The other is the issue of the functions of focus-sensitive operators. As for the first issue, it is observed that the basic function of focus is to mark all and only the new information of the sentence. But for the cases in which this principle is not observed, it is proposed that the focus in these cases in general plays a secondary function of triggering an additional emphatic scalar meaning. And yet, in these cases, the state of the matter is different between free focus and bound focus. It is also shown that contrary to the general belief that free focus contributes to the meaning semantically. Concerning focus-sensitive operators, we classify them into two groups, i.e., quantificational and scalar operators, and try to formalize their meaning in the framework of Pulman's(1997) 'higher order unification theory'.

In this paper, we review several two-stage randomized response techniques for gathering self-report data when persons are asked sensitive question. Also efficiencies and privacy protections based on the two-stage randomized response procedures are compared. Finally, we find optimal parameter conditions.

Nowadays, sharing data among organizations is often required during the business collaboration. Data mining technology has enabled efficient extraction of knowledge from large databases. This, however, increases risks of disclosing the sensitive knowledge when the database is released to other parties. To address this privacy issue, one may sanitize the original database so that the sensitive knowledge is hidden. The challenge is to minimize the side effect on the quality of the sanitized database so that non-sensitive knowledge can still be mined. In this paper, we study such a problem in the context of hiding sensitive frequent itemsets by judiciously modifying the transactions in the database. Unlike previous work, we consider the quality of the sanitized database especially on preserving the non-sensitive frequent itemsets. To preserve the non-sensitive frequent itemsets, we propose a border-based approach to efficiently evaluate the impact of any modification to the database during the hiding process. The quality of database can be well maintained by greedily selecting the modifications with minimal side effect. Experiments results are also reported to show the effectiveness of the proposed approach.

Randomized response technique is a survey technique for eliminating evasive answer bias. This technique is popular in social survey for sensitive issues. In this paper we present a simple and obvious procedure for estimating the population proportion of a sensitive group. Here, we shows the weak point in the method of Kim and Warde (2005). Also, it is found that the proposed procedure is more efficient than the ones of Warner (1965) and Kim and Warde (2005). Lastly we discuss the conditions that the suggested method will be more efficienct.

Today, with the development of the internet of things, wearable devices related to personal health care have become widespread. Various global information and communication technology companies are developing various wearable health devices, which can collect personal health information such as heart rate, steps, and calories, using sensors built into the device. However, since individual health data includes sensitive information, the collection of irrelevant health data can lead to personal privacy issue. Therefore, there is a growing need to develop technology for collecting sensitive health data from wearable health devices, while preserving privacy. In recent years, local differential privacy (LDP), which enables sensitive data collection while preserving privacy, has attracted much attention. In this paper, we develop a technology for collecting vast amount of health data from a smartwatch device, which is one of popular wearable health devices, using local difference privacy. Experiment results with real data show that the proposed method is able to effectively collect sensitive health data from smartwatch users, while preserving privacy.

최근 고감성 PET 사를 이용하여 생산한 PET 직물은 고감성 의류용 직물로서 많이 사용되고 있다. 이러한 고감성 의류용 PET 직물은 다양한 공정을 거치면서 장력이나 열 등의 영향을 받음으로서 사의 물성의 변화를 초래하여 감성 의류용도의 PET 직물에 많은 결점을 유발시킴으로서 직물 생산시 공정조건 설정 등의 어려움에 직면하고 있다. 이러한 고감성 의류에 치명적인 문제를 유발하는 문제점에 관한 감성사 제조시의 공정조건 변화와 관련된 연구논문은 많이 발표가 되지 못하고 있다. 따라서 본 연구에서는 국내 7개 원사 Maker의 cake내의 Denier 별 PET 사의 물성을 균일한 길이의 Layer를 설정하여 분석, 조사하고 Layer 별 물성 차이와 습·건열 열처리 온도에 따른 사의 수축률 등을 비교함으로서 감성 의류용 직물 생산에 필요한 기초 물성 Data를 제공하고 PET 사의 품질향상을 도모함으로서 최종 감성 의류용 직물 소재 개발에 기여할 수 있는 기초자료를 제공하고자 한다.

When sensitive topics such as gambling habits, drug addiction, alcoholism, tax evasion tendencies, induced abortions, drunk driving, past criminal involvement, and homosexuality are the focus of open or direct surveys, it becomes challenging to obtain accurate information due to nonresponse bias and response bias. People often hesitate to provide truthful answers. Warner introduced an ingenious method to address this issue. In this study, a new and unrelated randomized response model is proposed to eliminate misleading responses and nonresponses caused by the stigma associated with the attribute being investigated. The proposed randomized response model allows for the estimation of the population percentage with the sensitive characteristic in an unbiased manner. The characteristics and recommendations of the proposed randomized response model are examined, and numerical examples are provided to support the findings of this study.

API(Application Program Interface) 콜 시퀀스 분석은 분석 대상 프로그램에서 API 콜 정보를 추출한 후 분석하는 기법으로 다른 기법들에 비해 대상의 행위를 특징할 수 있는 장점이 있다. 하지만 기존의 API 콜 시퀀스 분석기법은 동일한 기능을 수행하는 함수를 상이한 함수로 잘못 식별하여 분석을 수행하는 문제점이 존재한다. 본 연구에서는 API 각각을 추상화시키는 방식을 추가하여 기존의 식별 문제를 해결하고 분석 성능을 향상시키고자 한다. 그 후 분석 대상들에서 획득한 추상화된 API 콜 시퀀스에 LSH(Locality Sensitive Hashing) 기법을 적용하여 각 분석 대상들 간의 유사도를 계산하고 유사한 유형끼리 클러스터를 형성하는 과정을 수행하였다. 본 연구는 악성코드 분석 시 악성코드의 유형을 파악하는 데 요긴하게 사용할 수 있으며, 최종적으로는 해당 유형 정보를 기반으로 악성코드 분석의 정확도를 향상시키는 데 기여할 수 있다.

Human Papillomavirus (HPV) infection is known as the main factor for cervical cancer which is a leading cause of cancer deaths in women worldwide. Because there are more than 100 types in HPV, it is critical to discriminate the HPVs related with cervical cancer from those not related with it. In this paper, the risk type of HPVs using their textual explanation. The important issue in this problem is to distinguish false negatives from false positives. That is, we must find high-risk HPVs as many as possible though we may miss some low-risk HPVs. For this purpose, the AdaCost, a cost-sensitive learner is adopted to consider different costs between training examples. The experimental results on the HPV sequence database show that the consideration of costs gives higher performance. The improvement in F-score is higher than that of the accuracy, which implies that the number of high-risk HPVs found is increased.
