After a short historical resume, screening is discussed on the basis of the current philosophy of Life insurance compaines in leading countries. This is followed by considerations with regard to the future in areas of major bearing on Life insurance screening which have emerged as important within the last decade. HIV-antibody testing is dealt with from the screening point of view followed by aspects regarding the applicability of tumour marker use in Life insurance medicine. Last but not least genetic testing will be addressed, taking into account prospects for the future, as well as the resulting responsibility in medical and underwriting terms. The major considerations and suggested guidelines can be summarized as follows: 1) Screening in Life insurance is a prerequisite for underwriting and is a well-functioning selection instrument. 2) Screening technologies are medically well defined and have to follow general clinical rules, also in the future. 3) Screening parameters should follow the patterns of diseases according to age and risk groups. 4) Screening parameters for prognostic use are legitimate as long as they are considered in conjuction with clinical medical observations and rules. 5) Screening technologies of a sensitive nature require very special rules for handling in the sense of "consequential ethies". 6) Screening parameters like HIV-antibody testing require ongoing scientific feedback in their new testing dimensions. 7) Screening in the form of genetic testing is as yet not used in Life insurance; its potential future role in Life insurfance medicine must, however, be discussed responsibly and in time. 8) Screening enables the insurance industry to rule out possible antiselection and provide for equal knowledge on the part of the insurance applicant and the insurer about impairements which shorten life expectancy. 9) Screening, informed consent, counselling and confidentiality must go hand in hand both now and to an even greater extent in the future.

October 31, 2017, a man named Saipov who follows ISIS killed 8 people and injured nearly 20 others by driving his truck to the riverside bicycle path in Manhattan, New York, in an act of terror. June 5, 2017, the Islamic extremist Yacqub Khayre held a woman hostage in a suburb of Melbourne, Australia, before being killed by the police. Various countries around the world including the UK, France, and Germany are in war against terrorism. The terrorists change their target from hard targets such as government officials to vulnerable soft target, intensifying the public's fear, and, unlike in the past when they were organized by governments or organizations, extremists such as ISIS followers are now acting on their own in the act of terrorism. Also, as they use vehicles, pressure cooker, and other objects that can be easily found for terrorism, it is becoming more difficult for the police to prepare against terrorist attacks. Meanwhile, some terrorism researchers argue that conversational techniques (negotiation) used by the police are now of no use, as shown in the cases like 9/11 attacks in 2001 and 2016 Nice attack in France in which the suspects committed terrorist attacks without leaving enough time for the police to take action and that, therefore, tactical suppression techniques need to be developed. Therefore, this study suggested police negotiation techniques are necessary not only for terrorist attacks but also for overall police work, including handling intoxicated people at police station, and proposed ways to activate conversational techniques for police organizations.

Multiple life models are useful in multiple life insurance and multiple life annuities when the payment times of benets in these insurance products are contingent on the future life times of at least two people. A reverse mortgage is an annuity whose monthly payments terminate at the death time of the last survivor; however, actuaries have used female life table to calculate monthly payments of a reverse mortgage. This approach may overestimate monthly payments. This paper suggests a last-survivor life table rather than a female life table to avoid the overestimation of monthly payments. Next, this paper derives the distribution of the future life time of last survivor, and calculates the expected life times of male, female and last survivor. This paper calculates principal limits and monthly payments in cases of male life table, female life table and last-survivor life table, respectively. Some numerical examples are discussed.

뇌성마비는 뇌 발달시기중 초기의 장애로 인하여 운동기능과 자세의 이상 등을 초래하는 질환으로 임상적으로 여러 유형으로 나누어진다. 뇌성마비 환자중에서 MRI 상 롤란도야의 이상소견을 보이는 경우 특이한 임상적 특징을 나타낸다고 보고되어있다. 본 논문에서는 이들을 대상으로 하여 뇌 단일광자컴퓨터촬영에서 나타나는 뇌혈류 이상 소견과 MRI 소견, 그리고 임상양상들을 비교해보고자 하였다. 임상적으로 뇌성마비로 진단된 80여명의 환자중 MRI상 롤란도야에 저산소성 뇌질환의 소견을 보인 7명을 대상으로 하였다. 이들에게 5-10mCi의 Tc-99m-ECD를 정맥주사후 뇌 단일광자컴퓨터촬영을 하였다. 뇌 단일광자컴퓨터촬영상에서는 특히 뇌피질, 선조체, 시상, 뇌간 및 소뇌의 혈류이상 소견을 분석하였고, 이를 MRI 소견 및 임상증상과 비교하였다. 모든 환자들은 만삭 또는 만삭에 가깝게 태어났고, 주산기 아사가 여섯명의 환자에서 있었다. 임상적으로는 긴장성 사지마비로 나타났다. Tc-99m ECD를 이용한 뇌 단일광자 컴퓨터촬영상 롤란도야의 혈류감소는 모두에서 확연하게 나타났다 MRI상에서 롤란도야의 이상소견은 5명에서는 확실하게 나타났고, 2명에서는 의심되었다. MRI상에서 이상소견을 보인 것보다 더 광범위한 부분에서 뇌단일광자컴퓨터촬영상 이상소견이 보였다. 결론적으로, 롤란도야에서 이상소견을 보인 환자는 임상적, 구조적, 그리고 기능적으로 특이한 소견을 보였다. Tc-99m-ECD를 이용한 뇌 단일광자컴퓨터촬영은 매우 민감하게 반영하였고, MRI보다 뇌의 더 광범위한 부위에서 이상소견을 보였다.

Purpose: Individual cancer patients often experience many symptoms that impair their quality of life at the end of life. Identifying symptoms at the terminal stage of cancer patients and possible imminent death prediction by using that assessment can assist physicians and patients in preparing the 'peaceful death'. This study examines symptom experience during the last 48 hours of life of terminal cancer patients, and determines whether symptom experience change with proximal to death. Methods: The medical records of 89 patients who died with terminal cancer at a hospital between July 1, 2003 and March 31, 2006 were reviewed. Symptom prevalence at the last 48 hours was analyzed along with the change of symptom experience at the admission, $48{\sim}24$ hours, and $24{\sim}0$ hours before death. Results: Median age of all patients was 62 years old (range $16{\sim}97$). During the last 48 hours, symptom prevalence was described as follows; unclear consciousness (57%), pain (30%), fever (22%), and dyspnea (19%). According to the primary site, unclear consciousness was notified the most frequent symptom, but fever was relatively high prevalence in patients of biliary origin cancer rather than other site cancer (P=0.012). As death was Impending, the prevalence of poor appetite and general weakness were decreased, while that of unclear consciousness was increased, which were all statistically significant (P < 0.05). Conclusion: The presence of unclear consciousness could be regarded as the symptom indicator as imminent death of terminal canter patients.

Purpose: To provide effective palliative care, it is important to predict not only patients' life expectancy but their discharge status at a time of inpatient admission to a hospice care facility. This study was aimed to identify meaningful life expectancy indicators that can be used to predict patients' discharge status on admission to the facility. Methods: Among 568 patients who were admitted to the hospice ward of P hospital from April 1, 2016 through December 31, 2017, 377 terminal cancer patients were selected. This retrospective cohort study was performed by using performance status, symptoms and signs, socioeconomic status, laboratory findings on admission. Results: Alive discharge was associated with a good performance status that was measured with the Karnofsky and Eastern Cooperative Oncology Group (ECOG) scales and the Global health and Mental status. Less anorexia, dyspnea, dysphagia and fatigue were also associated with symptoms and signs. Associated laboratory findings were close to normal Complete Blood Cell (CBC) count, Liver Function Test (LFT) and Blood Urea Nitrogen (BUN). Conclusion: Our findings suggest that Karnofsky Performance Status (KPS), ECOG, Global health, Mental status, anorexia, dyspnea, dysphagia, fatigue, CBC, LFT, BUN are meaningful indicators when predicting discharge status for inpatients. Further investigation is warranted.

By SDS-polyacrylamide gel elcctrophoresis (SDS-PAGE) and immunoblot analysis that a protein with 66,000 daltons in size was recognized by P. aeruginosa anti-exotoxin A from P. sp. PY002. The yields of exotoxin A in P. sp. PY002 culture were influenced by the concentration of iron in the culture media. Increasing of the exotoxin A production and siderophore production was made slight increasing in the MKB medium. On the other hand, to clone the gene encoding the exoloxin A genomic library of P. sp. PY002 was constructed in pBluescript SK(+). From this library a exotoxin A homologous gene was isolated by immunological hybridization method using P. aemginosa anti-exoloxin A as a probe. Two putative clones were isolated and designated pETA23 and pETA42. Thc restriction analysis ol pETA42 demonstrated that thc 1760 bp insert contained one NcoI, PvuII, SstI, Kpnl and EcoRI site and three SmaI and HaeD sites.

This study attempted to look into the effects of the job environment and job esteem on job satisfaction in the field of skin beauticians. To achieve this, a survey of their characteristics, job environment, job esteem and job satisfaction was carried out on 470 women in their 20s~50s working at skin care shops in the Seoul and Gyeonggi areas. First, it was found that the effects of the working environment on their vocational satisfaction, sense of belonging, level of contribution, wages and welfare, which are sub-factors of job satisfaction, are relatively high. This result shows that it is important to ensure proper resting facilities and resting areas. Second, it was shown that the higher the social evaluation, self-(implicit) assessment, future value, and self-fulfillment orientation, the higher the sub-factors of job satisfaction. This means that it is important to treat skin beauticians as professionals in order to improve their social recognition. The sub-factors of job environment-working conditions, organizational environment and job stability, and sub-factors of job environment-social evaluation, self(intrinsic) evaluation, future value and self-achievement orientation, had a major effect on the sub-factors of job satisfaction, respectively. Together with the general improvement in the sub-factors of job environment, the future value, as well as social evaluation, self(intrinsic) evaluation and self-achievement orientation, which together constituted the current value of job esteem, were the major factors affecting job satisfaction. Consequently, this study hopes to contribute to the development of the skin beauty industry by providing basic data on personnel management for skin care managers to improve skin beauticians' job satisfaction.

This study aims to identify the difference in the starting time of the dawn chorus of different species of birds and related environmental conditions. For this study, the bird songs were recorded every 2 hours a day starting from 2 hours before sunrise for a whole spring season (from April to June, 2014) in Korea. The recorded sounds were analyzed to find the starting time of each species' song by sonogram pattern using a sound analyzing program (Adobe Audition CC). To analyze the relationship between the environmental conditions and the time of the birdsong of each species, we collected the data of environmental conditions: daily precipitation, Julian date, time of sunrise and moonrise, temperature data and twilight time from the Korea Meteorological Office. As a result of this study, it was found that there are several statistical correlation between the starting time of the birdsong and environmental conditions (every environmental condition except daily precipitation and time of moonrise). Also, the difference of the starting time among each species were identified. The species were divided into 3 groups (early, mid and late) by their wake-up time. Ring-necked pheasant and yellow-throated bunting were categorized as 'Early' group and all woodpeckers were categorized as'Late' group. This study is significant as it first presented a classification of wild birds in Korea by the starting time of their dawn chorus. However, further studies are required to identify why each species to do their dawn singing at different times.
