The advances of medical technologies have not only prolonged human life span, but also extended suffering period for the patients with incurable medical diseases. Hospice movement was developed to help these patients keep dignity and lives peaceful at the end of their life. Since many patients prefer to spend the last moment of life at home with their family, hospice home care has become very popular worldwide. The purpose of this study for a promotion and development of hospice home care in Korea, and features basic research on medical profession's knowledge and attitudes to hospice home care. This study which was used for the research questionnaires developed by the researcher that were answered by 100 physicians and 127 nurses in a general hospital. Data were collected from April 22, 2002 to May 10, 2002. The SPSS was used to make a comparative analysis of the frequency, percentile, ANOVA, and x2-test. The results of the study were as follows; 1.The medical profession showed high level of knowledge of the definition and philosophy of hospice. However, the physician group of the examinees showed insufficient knowledge of the fact that hospice care includes bereavement care, while the nurse group's response to the same question showed a significant difference(x2=10.752, p=.001). 2.For whom the hospice home care is provided, 95.6% of the respondents showed very high level of knowledge as answering that the incurable terminal illness patients and their families are the beneficiaries of hospice care. The respondents counted nurses, volunteers, pastors, physicians and social workers, consecutively, as hospice care providers. More nurse were positive toward pastors than physicians in regarding as a hospice care provider by a significant difference(x2=11.634, p=.001). 3.For when to referral hospice home care to the patients, only 34.2% answered that patients with less than 6 months of survival time are advised to receive hospice care, reflecting very low level of knowledge. 23.0% of the physicians and 48.0% of the nurses answered that hospice care should be provided when death is imminent, making a significant difference between the two groups(x2=6.413, p=.000). 4.To promote hospice activities, 87.2% pointed out that it is crucial to make general people, including those engaging in the medical field, more aware of hospice. 79.7% answered that a national hospice management should be developed, marking a significant difference between the physician group and nurse group(x2=10.485, p=.001). 5.Advantages of hospice home care are 87.2% responded that patients can have better rest at home receiving hospice home care. Economical merit was brought forward as one of the advantages also, where there was a significant difference between the physicians group and nurse group(x2=7.009, p=.008). 6.The medical professions' attitude to hospice home care are 92.8% of the physicians answered that they would advise incurable terminally ill patients to be discharged from hospital, with 44.3% of them advising the patients to receive hospice home care after leaving the hospital. From the nurses' point of view, 20.9% of the terminally ill patients are being referred to hospice home care after discharge, which makes a significant difference from the physicians' response(x2=19.121, p=.001). 7. 30.6% of physicians have referred terminally ill patients to hospice home care, 75.9% of whom were satisfied with their decision. Those physicians who have never referred their patients to hospice home care either did not know how to do it(66.7%) or were afraid of losing trust by giving the patients an impression of giving up(27.3%). 94.9% of the physicians responded that they would refer their last stage patients to a doctor who is involving palliative care. 8.Only 36.2% of nurses have suggested to physicians that refer the terminally ill patients discharged from the hospital to hospice home care. Once suggested, 95.8% of the physicians have accepted the suggestion. Nurses were reluctant to suggest hospice home care to the physicians, as 48.8% of the nurses said they did not want to. From the result of this study the following conclusion can be drawn, the medical profession's awareness of general hospice care has been increased greatly compared to the results of the previously performed studies. However, this study result also shows that their knowledge of hospice home care is not good enough yet. There is a need for high recommended that medical education institute and develop regular courses on various types of hospice care. Medical field training courses for physicians and nurses will be very helpful as well. It is also important to train hospice experts such as palliative physicians and develop a national hospice management urgently in order to improve the hospice care in Korea.

This study was conducted to compare the characteristics of high performane areas for family planning with that of low performance areas and to find factors which strongly affected contraceptive practice behavior. For the study, eight areas were selected from 274 rural family planning canvassing areas of Korean Population Policy and Program Evaluation Study, which was an action study operated in all areas of Cheju Island from July 1, 1976 until December 31,1979. As a first step of the action study, Cheju Island was devided up 318 family planning canvasser areas Each area was consisted of 200 households in rural district and 300 households in urhan one Duriog the period of project, each canvassing area had been managed by a female family planning canvasser, selected by director of health center considering several individual conditions needed for family planning activities Basic activities of canvassers were to counsell all the eligihie couples in own charged area about family planning methods and also to distribute contraceptives such as condoms and oral pills. In case couples desire to accept sterilization including vasectomy and tubal-ligation, the canvassers played a linking role connecting potential client with family planning field workers. Canvassng areas shows significant differentce in performance for family planning, nevertheless they are supposed to have almost the same conditions regarding family planning distribution channel. Because the purpose of the Cheju project was to eliminate all the problems that existed in governmental distribution system, that is to remove geographic, economic, cognitive and administrative barriers Accumulated performances of family planning methods accepted by residents in each area were calculated by eligible women aged 14-49. And then canvassing areas were ranked according to performance score. Consequently, 4 areas in extremely high and low family planning performance areas were selected respectively. Major results were obtained by comparing characteristics of high performance area with that of low performance areas, which are as follows: 1. The mean number of living children was about the same both in high and low performance areas for family planning. But respondents' mean age (38.5) in high performance areas was higher than that (37.0) in low performance areas 2. Respondents' perception in the expectant educational level of others' children in high performance areas was higher than that in low performance areas, although respondents educational level, monthly expenditure and ratio of children in high school and above was not different. 3. Ratio of ownerships of TV and newspaper in high performance areas was highen than that in low performance areas 4. The duration of canvasser' charge in high performance areas was longer than that of low performance areas, showing the fact that canvassers didn't move cut in high performance areas 5. In high performance areas, canvassers' houses were relatively located in the center part of the village. And so villagers resided in near distances from the anvasser's house 6. 4H clubs' activities in high performance areas were more active than those in low performance areas Therefore it was assumed that cohesiveness of community in high performance areas were stronger than that in low areas. 7. Canvassers' family planning practice rate was higher than that in low performance areas, and also canvassers' human relationship was more sociable than that of canvassers in low performance areas. 8. Fourteen variables which showed relatively high significance level in $X^2$ and F test were selected as independent variables for stepwise regression analysis. According to the results of regression analysis. five of 14 variables-distributors education level ($R^2$=.4439), duration of distributor's charge ($R^2$=.6166), 4H club activities ($R^2$=.6697), canvasser's contraceptive practice ($R^2$=.7377) and location of distributions house ($R^2$=.8010) explained 80.1 percent of total variance.

Recently, there is a substantial interest in implementing Business Process Management System(BPMS) among enterprises with the purpose of business process innovation. BPMS redesigns and coordinates business processes in terms of both automated steps and human involvement in order to maximize the value of both involved people and systems. The reason why BPMS is getting attention from top managers is that it has the possibility to optimize the business processes by cycling the process of modeling, execution, monitoring, evaluation, and redesigning work processes. Thus, it has created high expectations about not only productivity improvement but also business process innovation. However. having an innovative nature, which is used for process innovation, BPMS implementation has great potential to stir up employee resistance. The analysis and the discussion about the prevention of the resistance against IS(Information Systems) is important because IS change the way people work and also alter the power structure within the organization, in general. The purpose of this study is to investigate factors that have an impact on the effective adoption of BPMS at the enterprise level. To find out these factors, this study considers two characteristics of BPMS: First. BPMS shares some characteristics with other enterprise-wide IS such as ERP. Second, it has special BPMS-specific characteristics. Due to the lack of previous research on BPMS adoption, interviews were carried out with IT-consultants and CIOs who conducted BPMS projects previously to find out BPMS-specific features that would make BPMS unique when compared to other enterprise-wide IS. As a result, the monitoring function was chosen as the main BPMS-specific factor. Thus, this paper reviewed studies both on enterprise-wide IS adoptions, which applied Technology Acceptance Model (TAM) and secondly on computer based monitoring to find out factors that would influence the employees' perception on the monitoring function of BPMS. Based on the literature review, the study suggested three factors that would have an impact on the employee's perception of the monitoring function: fairness of enterprise evaluation system, fairness of the boss, and self-efficacy of their work. Three factors that would impact the enterprise-wide IS adoption were also set: the shared belief in the benefit of BPMS, training, and communication. Then, these factors were integrated with TAM. Structural equation modeling was used to test hypotheses, out factors that would impact the employees' perception on the monitoring function of BPMS. Based on the literature review the study suggested three factors that would have an impact on the employee's perception of the monitoring function: fairness of enterprise evaluation system, fairness of the boss, and self-efficacy of their work. Three factors that would impact the enterprise-wide IS adoption were also set: the shared belief in the benefit of BPMS, training, and communication. Then, these factors were integrated with TAM. Structural equation modeling was used to test hypotheses. The data analysis results showed that two among three monitoring function related factors - enterprise evaluation system and fairness of the boss - were significant. This implies that employees would worry less about the BPMS implementation as long as they perceive the monitoring results will be used fairly for their performance evaluation. However, employees' high self-efficacy on their job was not a significant factor in their perception of the usefulness of BPMS. This is related to cases that showed employees resisted against the information systems because they automated their works (Markus, 1983). One specific case was an electronic company, where the accounting department workers were requested to redefine their job because their working processes were automated due to BPMS implementation.

북한에서는 한민족의 전통 구비설화를 개작하여 아동들을 위한 동화로 활용한다. 한민족의 대표적인 설화 <해와 달이 된 오누이> 역시 그들의 사관에 따라 변형되었다. 북한 애니메이션 <오누이와 나무군>은 본래의 설화형태에서 오누이가 하늘로부터 구원되고 해와 달이 되는 결말이 다른 모습으로 대체되어 있다. <오누이와 나무군>의 각색은 북한의 문예사관이 반영된 형태이자, 북한의 옛이야기 수용문화를 잘 이해하게 한다. 이에 본고는 분단이전의 설화자료를 통해 이 설화의 원형을 파악하고, 남북의 현대적 매체로 재창작된 작품들을 대상으로 그 서사 상의 공통점과 차이점을 분석하였다. 또한 북한의 독특한 관점이 발견되는 애니메이션의 개작 범위와 그로 인해 전환된 의미에 대해 분석하여 서사적 가치에 대해서 논하였다. 이 애니메이션은 오누이가 위압적인 호랑이의 공격을 이겨내고 승리하는 과정을 충실히 담아내어, 여타 남북의 현대적 창작물에 비해 이 설화의 본래 의미를 풍요롭게 구현하고 있다. 다만 본래 설화의 결말 속 하늘의 상징성이 축소되어, 아무도 지켜주지 못할 때 오누이의 내면에서 긍정적 신념이 발동되는 가능성의 정도가 약화되는 한계점을 보인다. 그럼에도 구체적인 성공과정으로 오누이의 역량에 대해 사실적으로 이해하게 하는 특장을 지녔다는 점은 부인할 수 없으며, 오누이 성공의 또 다른 형상으로 본래 설화의 의미를 잘 담아내고 있는 색다른 작품이라고 할 수 있다. 통일된 미래사회에서 이 애니메이션은 당시 북한의 사회문화를 이해할 수 있게하는 중요한 자료이자, <해와 달이 된 오누이>의 핵심을 잘 담고 있으면서도 오누이의 성공을 실제 삶과 가까운 범위로 이해하고 능동적 실천력을 공감하게 하는 아동문학으로 활용될 수 있을 것이다.

인간의 기본 욕구 중 하나인 존중의 욕구를 충족시키지 못하는 사회적 배제는 이를 지각한 사람들로 하여금 물리적 따뜻함을 추구하도록 만든다고 알려져 있다. 그러나 사회적 배제가 따뜻함을 추구하게 만드는 현상이 조명의 색 같은 감성적이고 상징적인 차원에도 일반화될 수 있을지에 대해서는 연구가 드물었다. 본 연구는 지각된 사회적 배제가 따뜻한 조명 선호에 미치는 효과를 검증하기 위해 이루어졌으며, 이를 위해 두 가지 실험을 수행하였다. 실험-1은 어제 사람들로부터 존중받은 사람은 사회적 배제를 지각하지 않은 집단으로, 존중받지 못한 사람은 사회적 배제를 지각한 집단으로 구분한 후, 따뜻한 조명(3000K), 중립적 조명(4000K), 차가운 조명(6000K)에 대한 선호도를 측정하였다. 결과적으로 사회적 배제를 지각한 집단은 그렇지 않은 집단보다 따뜻한 조명 선호도가 강했고, 차가운 조명 선호도는 약했다. 또한 사회적 배제를 지각한 집단은 중립적 조명보다 따뜻한 조명을 강하게 선호하는 반면, 차가운 조명을 약하게 선호함을 확인하였다. 실험-2는 실험-1과 동일한 방식으로 집단을 구분한 후, 따뜻한 조명이 적용된 공간, 중립적 조명이 적용된 공간, 차가운 조명이 적용된 공간에 대한 선호를 측정하였다. 결과적으로 사회적 배제를 지각한 집단은 그렇지 않은 집단보다 따뜻한 조명이 적용된 공간에 대한 선호도가 강했고, 차가운 조명이 적용된 공간에 대한 선호도는 약했다. 아울러 사회적 배제를 지각한 집단은 중립적 조명이 적용된 공간보다 따뜻한 조명이 적용된 공간을 강하게 선호하는 반면, 차가운 조명이 적용된 공간은 약하게 선호함을 관찰하였다. 본 연구는 장애인, 다문화 가정, 이주 노동자와 같이 사회적 배제를 경험한 사람들의 생활공간 디자인, 이들을 대상으로 한 인공지능 상담 서비스 및 친구 캐릭터 개발 등에 시사점을 준다.

이번 연구는 한국 다문화 사회에서 한반도 통일의 가치토대를 어떻게 확립할 것인지를 탐구하는데 주요 목적이 있다. 이번 연구의 주제는 다문화 구성원들, 특히 북한 주민들과 새터민, 외국인 노동자, 국제결혼 이주자 및 그 자녀들이 과연 한번도 통일의 가치를 공유할 수 있는지, 즉 한민족 정체성과 그것의 가치분담이다. 이를 위해 이번 연구에서는 '문화 개념의 다문화 수준별 적용'에 관한 기존의 연구논문을 활용하고, 그 한계를 밝히며, 이를 보완할 수 있는 하나의 대안으로서 '정서(emotion)'의 다문화적 적용 가능성을 제시해보고자 한다. 기존의 문화 개념의 적용의 양상은 다음과 같다. 첫째, 문화 개념을 '의미의 패턴'으로 간주하는 경향으로서 주로 상징과 해석에 초점을 둔다. 이는 주로 타문화를 이해하는데 유용한 방식이라고 할 수 있다. 예컨대, 국제결혼 이주민이 초기 한국 사회의 정착시기에 한국 사회를 이해하는 방식이라고 할 수 있다. 둘째, 문화 개념을 지속적인 완전성을 향한 과정으로 이해하는 경향으로서, 이는 주로 자문화를 확인하는 방식이라고 할 수 있다. 예컨대, 국제결혼 이주민이 한국 사회에 정착하면서 본격적인 삶을 영위할 때 '한국인'으로서 정체성을 확인하는 방식이다. 하지만 이와 같은 기존의 연구성과를 북한 주민, 새터민, 국제결혼 이주민 가정의 자녀에게 적용했을 때에는 일정한 한계가 보인다. 첫째, 북한 주민들은 현재 북한 정권의 특성상, 다문화 사회에 대한 거부감이 크고, 단일민족주의를 이데올로기적 차원에서 이해할 가능성이 매우 크다. 즉 북한 주민들이 자문화 차원에서 민족 정체성을 강하게 확인하더라고, 매우 폐쇄적이라고 할 수 있다. 둘째, 새터민의 경우에는 자문화 확인의 정도는 강하지만, 한국 사회의 정착과정에서 경험하게 되는 사회경제적 차별로 인해 자신들만의 정체성 확인에 그친다. 셋째, 국제결혼 이주민 가정의 자녀들과 그 부모들은 모두가 '한국인'이라는 정체성 수준은 매우 높았다. 다만 이주민 부모의 경우에는 자신들의 문화에 대한 정체성은 그대로 유지하고 있었다. 그러나 순혈주의의 측면에서 이들 모두에 대한 차별적 인식은 여전히 강하게 남아 있는 실정이다. 한반도 통일에 대한 가치의 토대는 다문화 구성원들 모두가 분담할 수 있는 '정체성'의 문제이다. 이를 삶의 영역에서 확인하고 전개할 수 있는 방안은 각 구성원들의 특성들을 모두 고려할 수 있을 때에만 가능하다. 기존 연구의 문화 개념을 다문화 수준별로 접근했을 때 근본적인 문제는 내면적으로 구성원들 모두가 한국 다문화 사회에서 한민족 정체성에 대한 어떤 공통된 분담을 가질 수 있는지에 대한 답을 명료하게 제시하지 못했다. 이런 점에서 다문화 사회에서 한반도 통일의 가치토대는 외면적이고 제도적인 문제라기보다는 내면적이고 정체성에 관한 문제이다. 이 문제는 결국 다문화 구성원들이 관계의 삶의 영역에서 도덕적 행위자라는 점에서 이들의 정서가 문화적으로 전개되는 과정에서 보다 세밀하게 진행되어야 할 것이다.

As a result of measuring illumination and making up a question at home visit directly by investigator who trained over twenty days period from October 4 to 24, 1990, in order to render help which illumination problem against house, society against eyes or framing of health instruction potgram by seizing natural lighting actual conditions of house and actual conditions of wearing spectacles and by investigating interrelationship, I can summarize as follows. 1) In property of investigation subject, woman 66.9%, In an age, the twenties was largest of 27.4%, the forties was 20.2%, the fifties was 18.6%, the thirties was 17.4%. In academic career, those of upper secondary school grauates was largest of 28.6%, those who possess university career was 25.9%, those who middle school career was 20.9%, decoding of Korean alphabet was 2%. 2) By a residence area, a big city was 43.3%, farming and fishing villages were 20.3%, the rest was a small town and the administrative office of town, township. In positon of house, the middle area was 43.6%, resident of suburb area was 38.0%. In form of house, a Korean-style house was 40.8%, a western-style house was 34.8%, an apartment house was 11.0%. In the a standard of living, the middle classes 77.2%, the lower classes were 15.3%. In residential house unit of area, from 21 to 30 unit of area was largest of 31.5%, from 10 to 20 unit of area was 19.9%, from 31 to 40 was 18.7%. 3) The wearing spectacles rate of study user was 44.1%. By the area, those who wearing spectacles was more than a half of 50.8% in the resident of big city area. As passing from the farm area to the city, that is being resident of big city was high wearing spectacles rate. In position of house, as being residence in central street showed high wearing spectacles rate. (central street was 51.5%, the middle area was 44.5% and the suburb area was 40.1%.) It seemed similarity difference a variable by position of house from wearing spectacles in standard of 1%. By form of house, wearing spectacles rate those who resident in apartment house was 49.5%, that rate those who resident in a western-style house was high of 49.0%, that rate those who resident in a Korean-style house was the lowest 39.0%. By social position of resident in room, in students case who study showed very high, as university students were very high of 62.3% idn wearing spectacles rate, middle and high school students 'were 50.0%, members of society were 47.6%, workers 20.3%. It seemed similarity difference from academic career in standard of 1%. By an age, the thirties was high of 54.1% in wearing spectacles rate, the twenties was 43.2%, the teenage was the lowest of 11.8%. 4) In illumination of study, over 200Lux was high of 40.1%. but below 99Lux which inappropriate illumination to see the books was 32.4%. Average by area, below 99Lux was 22.7% and over 400Lux was 50.0% in case of wooden floor. As examine by area, below 99Lux was high of 27.0% a case of wooden floor in the big city area, it was not good in illumination passing from the farm area(15.0%) to the city(19.0%). Average illlumination by area of the main living room below 99Lux was high of 37.5%, less than 200Lux was 58.5% of whole. In general, illumination of the main livingroom was inappropriate. By area, the big city was 32.5% below 99Lux, the middle and small city area were 33.8%, town and township area were 45.0%, farming and fishing area were 42.8%. By area, in the big city, illumination of study was 52.5% over 200Lux and 28.9% below 99Lux. In case of the middle and small city, study user of below 99Lux was 38.8% and over 200Lux was 46.9%. In case of the seat of town township, below 99Lux was 34.1% and over 200Lux was 39.7%. In case of farming and fishing area, illumination of study was 33.4% below 99Lux and 48.4% over 200Lux. It tends to high rate of inappropriate illumination. 5) By position of house, in case of wooden floor, less than 100Lux was 24.5% in central street. It was bad illumination than others position of house. In case of the main livingroom, less than 100Lux was 40.4% in the suburb area. It was bad iliumnation than others position of house. In case of study, less than 100Lux was 35.4% in the middle area, it was worse in illumination. In case of the main living room, is seemed similarity difference in standard of 1%. 6) By form of house, in case of wooden floor, illumination of less than 100Lux was 23.8% in a western-style house, it was bad illumination than others form of house. In case of the main livingroom, illumination of less than 100Lux was 47.4% in a Korean-style house, it was remarkably bad illumination than others form of house. In case of study, a Korean-style house was 38.8%, it was very bad illumination than others form of house. In case of the main livingroom and study, it seemed similatrity difference each as P < 0.01 and P < 0.05 in standard of 1%. 7) The wearing spectacles rate of those who use room of illumination over 400Lux was 40.7%, and that of those who use room of illumination less than 100Lux was 28.1%. It seemed similarity differecce in standard of 1%. 8) In period of wearing spectacles, 21.3% of total investigator-highest-was from before five years, 8.6% was from before three years. Among those who use of illumintion less than 99Lux, 34.0% began to wear spectacles from before two years 31.7% was from before five years, 30.3% was from before four years. It seemed similarity difference from period of wearing spectacles by illumination in standard of 1 %. 9) Among cause which sight grow worse, the first was that it was each 33.2% and 27.4% in response rate because watch TV nearly to wearing spectacles person and non-wearing person. The second was that a lot of seeing books was 25.3% in wearing spectacles person and response rate for dark illumination was 7.4% in nonwearing spectacles person. It seemed similarity difference in standard of 1%. (P < 0.01). 10) In experience which take medicine good for eyes, it was 50.1% in wearing spectacles person and 8.5% in non-wearing spectacles person. It seemed similarity difference in standard of 1%(P < 0.01). As we have seen above, inappropriate illumination can be a cause of wearing spectacles. Nevertheless, actually, is realities to indifferent against illumination of house. So it must learn knowledge about health obstacle of illumination through society instruction and school eduction against students as well as general residents. In case that natural lighting is inappropriate structural of house, we must be able to maintain appropriate illumination through artificial illumination. And so eyes which is core of human life have to be protected, related the authorities, related group, and all health medical personnel will organically cooperate with and make efforts.

현대시대는 환자에 대한 의료제도가 의료서비스 개념으로 변화되고 있다. 이렇게 인간의 권리가 높아지고 환자가 고객이 되는 시대로 변화됨으로써 환자의 권리나 요구도 날로 증가되고 있으며 이를 바탕으로 여러 가지 병원 시스템도 환자의 편의나 요구에 맞춰지고 있는 것이 현실이다. 이로 인해 일반촬영 검사 중 Portable 검사의 Case도 점차 증가하고 있는 추세이다. Portable 검사의 Case가 증가하면서 병실, 중환자실, 수술실, 회복실에서 Portable검사로 인하여 주변 환자들의 원하지 않는 의료 피폭이 발생하기 때문에 법적으로도 이를 규제하고 있다. 실제로 진단용 방사선 발생장치의 안전관리에 관한 규칙 중 방사선 방어시설의 검사기준에서 "수술실, 응급실 또는 중환자실 외의 장소에서 촬영할 경우 반드시 이동형 진료용엑스선 방어칸막이를 갖추어야 한다."고 명시되어 있지만 이는 거의 시행되어지지 않고 있다. 따라서 X-ray Potable 검사를 통해 주변 환자가 받는 피폭선량을 알아보고 피폭선량 감소 방안을 알아보고자 하였다. 본 연구는 Mobile Portable 장비에서 Collimator 주변을 차폐하여 차폐 전과 후의 선량 변화, Portable tube와 Collimator의 각도 변화에 따른 차폐 전과 후의 선량 변화, 환자 침대의 거리변화에 따른 차폐 전과 후의 선량 변화를 각각 측정한 뒤 차폐효과를 알아보았다. 연구 결과 Collimator 주변을 차폐한 후 선량 변화는 차폐하지 않았을 때보다 약 20%의 차폐효과를 보였다. Portable 검사 중 비 차폐 시 각도가 $0^{\circ}C$, $90^{\circ}C$, $45^{\circ}C$ 순서로 피폭선량이 증가하였으며, 각도를 주었을 때 Collimator 주변을 차폐하면 피폭 선량은 감소하였다. 또한 환자 침대 거리는 비 차폐 시 0.5m보다 1m에서 피폭선량이 현저히 감소하였고 침대 간 거리 변화 시 Collimator 주변 차폐 후 선량 변화는 감소하였다. 주변 환자 피폭선량 감소 측면에서 볼 때 침대거리를 가능한 멀리 떨어뜨리는 것이 가장 좋은 방법이며 차폐효과가 약 100% 내외로 상당한 효과를 볼 수 있다. 그 다음은 Collimator를 차폐하는 방법으로 차폐효과가 약 20% 정도를 나타내며, 각도를 제한하는 방법으로 약 10% 내외의 효과를 나타낸다. Portable 검사 시 환자 피폭선량을 감소하기 위해 가능한 환자 및 보호자를 적정거리 이상으로 이동시킨 후에 실시하는 것이 가장 좋겠지만 환자가 움직일 수 없고 침대가 고정되어 있는 상태에서는 Collimator 주변을 차폐하는 방안을 제안한다. 또한 검사를 시행할 때 tube와 Collimator의 각도를 가능한 90도로 시행하도록 하고 90도가 안될 경우는 0도로 시행하되 45도는 가능한 지양하도록 한다. 방사선관계종사자들은 Portable 검사에서 위와 같은 결과들을 인식하고 실제 본인에게 적용시켜야 하며 효율적인 방사선 방어와 피폭선량을 감소시킬 수 있는 방안에 대한 노력과 연구에 힘써야 할 것으로 사료된다.

E-commerce 환경의 발전으로 소비자들은 다양한 상품들을 한 자리에서 폭 넓게 비교할 수 있게 되었다. 하지만 온라인 쇼핑몰에 올라와있는 상당량의 주요 상품 정보들이 이미지 형태이기 때문에 컴퓨터가 인지할 수 있는 텍스트 기반 검색 시스템에 반영될 수 없다는 한계가 존재한다. 이러한 한계점은 일반적으로 기존 기계학습 기술 및 OCR(Optical Character Recognition) 기술을 활용해, 이미지 형태로 된 키워드를 인식함으로써 개선할 수 있다. 그러나 기존 OCR 기술은 이미지 안에 글자가 아닌 그림이 많고 글자 크기가 작으면 낮은 인식률을 보인다는 문제가 있다. 이에 본 연구에서는 기존 기술들의 한계점을 해결하기 위하여, 딥러닝 기반 사물인식 모형 중 하나인 SSD(Single Shot MultiBox Detector)를 개조하여 이미지 형태의 상품 카탈로그 내의 텍스트 인식모형을 설계하였다. 하지만 이를 학습시키기 위한 데이터를 구축하는 데 상당한 시간과 비용이 필요했는데, 이는 지도학습의 방법론을 따르는 SSD 모형은 훈련 데이터마다 직접 정답 라벨링을 해줘야 하기 때문이다. 본 연구는 이러한 문제점을 해결하기 위해 '훈련 데이터 자동 생성 프로그램'을 함께 개발하였다. 훈련 데이터 자동 생성 프로그램을 통해 수작업으로 데이터를 만드는 것에 비하여 시간과 비용을 대폭 절감할 수 있었으며, 생성된 훈련용 데이터를 통해 모형의 인식 성능을 높일 수 있었다. 더 나아가 실험연구를 통해 자동으로 생성된 훈련 데이터의 특징별로 인식기 모형의 성능에 얼마나 큰 영향을 끼치는지 알아보고, 성능 향상에 효과적인 데이터의 특징을 분석하였다. 본 연구를 통해서 개발된 상품 카탈로그 내 텍스트 인식모형과 훈련 데이터 자동 생성 프로그램은 온라인 쇼핑몰 판매자들의 상품 정보 등록 수고를 줄여줄 수 있으며, 구매자들의 상품 검색 시 결과의 정확성을 향상시키는 데 기여할 수 있을 것으로 기대한다.
