직무에 기반을 둔 인사관리는 공공부문의 경쟁력과 생산성 향상, 개인 동기부여와 성과향상 측면에서 강조되어오고 있다. 하지만 주로 금전적 보상과 연계되는 일련의 제도는 공공부문의 목표불명확성으로 인하여 한계에 직면하고 있다. 따라서 공공부문의 직무기반 보상은 직무의 고유한 특성과 가치를 적절하게 반영한 필요가 있다. 특히 경찰조직의 경우에는 사회의 안녕과 질서유지를 위한 다의적인 목표를 추구하는 만큼 중요직무급의 도입에 있어서 구성원들의 인식과 판단기준, 의사소통 구조를 반영한 제도의 설계가 필요하다. 본 연구에서는 경찰조직에서 중요직무급의 도입에 있어서 고려해야 할 중요한 요인들과 그것이 제도에 대한 기대효과에 미치는 영향력을 분석하였다. 경찰관을 대상으로 한 온라인 설문조사를 실시하였으며, 총 3,354명을 최종분석에 활용하였다. 인구사회학적 특성에 따른 업무의 중요도와 난이도, 상관의 지시수준을 살펴보고 다중회귀분석을 통해 기대효과에 미치는 영향력을 분석하였다. 분석결과, 중요도, 난이도, 상관의 지시는 모두 기대효과에 긍정적인 영향을 미치는 것으로 나타났다. 조절효과 분석에서는 중요도×상부지시가 부(-)의 효과를 미치는 것으로 나타났다. 즉, 중요직무급의 운영에 있어서 직무의 중요도와 난이도, 상부지시와의 연관성이 높은 업무 위주로 중요직무를 선정할 필요가 있다. 또한 상부지시는 중요도의 긍정적인 효과를 감소시킬 수 있는 만큼 업무 자체가 내포하고 있는 중요도를 우선적으로 고려해야할 것이다. A human resource management system reflecting a job-based payment has drawn attention in the public sector as means to raise productivity, competitiveness and performance. However, a series of HRMSs focusing on the monetary and external rewards has faced its limitations because of goal ambiguity in the public sector. Therefore, many researchers stressed that a job-based payment should appropriately assess and reflect innate features and value of the job. Police organization pursues multiple goals in order to maintain public security and social order. Therefore, the introduction of the job-based payment system need to be designed reflecting police officers’ perception of their duties and a way of communication among them. This study examined the several influential factors and their impacts on the expected effectiveness of the job-based payment system. The impacts of independent variables were inspected by applying a multiple regression analysis. Results showed that all the independent variables had a positive and statistically significant effects on the dependent variable. Additionally, the moderating effect of the interaction term ‘job importance × instructions from the upper part’ turned out to be negative, which was statistically significant. Based on the empirical test results, theoretical and practical implications were discussed.

경찰 성과관리 제도이해 및 기대효과에 미치는 영향변수에 대한 연구

강영철 ( Young Cheol Kang ),최낙범 ( Nak Bum Choi ),임준형 ( Joon Hyung Lim ) 한국경찰학회 2015 한국경찰학회보 Vol.17 No.6

공공부문에서 성과관리제도는 신공공관리의 흐름에 맞춰 본격적으로 도입되었음에도 불구하고 여전히 제도의 이해와 효과성에 대한 심도 있는 논의는 부족한 실정이다. 성과관리 제도를 통한 조직 관리는 성과를 중심으로 관련된 조직 내의 제도시행 및 운영방향 등이 서로 유기적으로 연계되어 지속적인 성과 및 업무의 개선이 나타나는 것을 의미한다. 성공적인 성과관리제도 운영을 위해서 조직구성원들이 제도운영을 통하여 성과를 인식하는 수준과 제도에 대한 이해를 바탕으로 지속적인 관리와 제도개선을 이루어 나가는 것이 핵심요인이라 할 수 있다. 따라서 구성원들이 제도에 대하여 인식하는 수준을 파악하는 것은 매우 중요하다고 볼 수 있다. 이러한 문제의식에 따라서 본 연구에서는 경찰 조직을 대상으로 성과관리 제도의 이해와 기대효과에 대한 인식에 영향을 미치는 중요 영향변수들을 도출하고 이들 간의 관계를 실증적으로 분석하고자 하였다. 실증분석을 위해서 전국의 경찰관을 대상으로 한 설문조사를 실시하였다. 분석결과 성과지표의 명확성, 참여, 업무관련성은 제도에 대한 이해와 기대효과에 직,간접적인 영향을 미치는 것으로 나타났으나 기관장의 관심은 제한적인 수준에서만 영향을 주는 것으로 나타났다. 실증분석결과를 토대로 경찰조직의 성과관리에 필요한 정책적 시사점을 도출하였다. Performance management system(PMS) has been widely adopted in the public sector in keeping with prevailing new public management (NPM) trends. However, considerable debate about understanding of the system and its effectiveness is still limited. Organizational management through performance management system implies that implementation of the system and related factors are systematically connected and innovation of tasks and improvement performance plans are centered around employees` performance. Examining employees` levels of understanding of the system itself and facilitating continuous innovation of the system are essential for successful implementation of PMS. Therefore, this study tries to examine the impact of determinants affecting understanding and expected effectiveness of PMS of police agency. A survey was conducted and a structural equation modeling was used in order to test hypotheses. Results show that clarity of performance measures, participation, and job relevance are positively related to understanding of the system and to expected effectiveness. However, leader`s concern doesn`t show statistically significant impact. Based on the empirical test results, theoretical and practical implications are discussed.

전자정부시스템이 공공조직 의사결정에 미치는 영향

임준형(Joon Hyoung Lim),강영철(Young-Cheol Kang) 한국지역정보화학회 2013 한국지역정보화학회지 Vol.16 No.4

본 연구는 공공부문에서 정보기술이 의사결정에 미치는 영향에 대한 실증 연구가 부족한 가운데, 국정운영을 위한 기간시스템으로서 전 중앙행정기관에서 활용되고 있는 정부업무관리시스템을 대상으로 의사결정지원효과와 그 영향요인을 규명하였다. 정보기술이 조직의사결정에 미치는 영향에 관한 선행연구를 검토하여 가설을 도출하고, 중앙공무원들을 대상으로 설문조사를 실시한 결과에 대한 경로분석을 실시하였다. 분석 결과, 다수의 조직이 동일한 시스템을 도입하더라도, 이를 통한 의사결정의 향상은 조직문화와 리더십과 같은 조직특성과 시스템을 활용하는 사용자의 직무태도, 정보기술역량, 직무특성 등에 따라 달라진다는 점이 발견되었다. 본 연구의 의의는 정부조직에서 어떠한 조건들이 정보기술도입에 의한 의사결정향상을 촉진하거나 저해하는지 실증적으로 규명한 점에 있다. 향후 스마트기술 등을 대상으로 하는 다양한 후속 연구들을 통해 정부조직의 의사결정을 위한 정보기술의 역할에 대한 보다 풍부한 논의가 지속될 필요가 있다. This research explores what organizational and individual factors explain the performance impact of an information system on decision making in government agencies. Drawing insights from the relevant literature, a conceptual framework was developed to explain the utilization of an information system and its impact on decision efficiency and effectiveness. Data were collected from a questionnaire survey of public officials in central-level agencies. Results of analysis find that the utilization of an information system is significantly and positively associated with a user’s IT competency and non-routineness of a task, whereas negatively associated with a user’s withdrawal behaviors at work such as absenteeism and tardiness. In addition, IT-aided decision performance is positively associated with human-oriented culture, managerial leadership, and the level of the system utilization. The system utilization is also found that mediate the impact of user characteristics on the decision performance.

강영철,김예철,문석배,김국기,이영근 대한신경외과학회 1977 Journal of Korean neurosurgical society Vol.6 No.1

Choriocarcinoma, a rare malignant neoplasm of trophoblastic tissue, is characterized by early blood borne metastasis to distant organs such as lung, liver and brain. Involvement of central nervous system by metastatic choriocarcinoma may be manifested as acute or subacute apoplexy due to vascular invasion with tumor emboli. Therefore the diagnosis of cerebral choriosarcinoma should be suspected in women of child bearing age presenting the signs of acute or subacute intracranial pathology. We present and discuss 2 cases of intracerebral metastatic chorioiarcinoma simulating cerebrovascular accident. One case, a 35 years old Korean housewife, was admitted to the department of neurosurgery, Kyung Hee University Hospital, with the chief complaints of headache, vomiting, focal seizure and right sided hemiplegia for 2 weeks' duration. She had a history of irregular vaginal bleeding from 3 months before admission. On admission, there were flaccid paralysis of the right extremities with right sided facial palsy, central type and neck stiffness in moderate degree. Gynecologically, round tumor mass about 1.5㎝ in size at vagina was palpable and urine HCG was positive. Chest X-ray film showed scattered multiple nodular densities at both lung fields. Carotid angiogram showed vascular tumor in the fronto-parietal region. Brain scan revealed increased uptake in the parietal area. She died suddenly 3 days later at home. Another case, 39 years old housewife, was admitted to the hospital with unconscious state. Although she had an operation of hysterectomy 5 months before admission due to massive vaginal bleeding, she was quite well till several hours prior to admission when she complained of headache and vomiting followed by sudden loss of consciousness. Neurologic examination revealed deep comatose state with full dilated and fixed pupil. Chest film showed several nodular densities at both lung fields. Carotid angiogram revealed avascular space occupying lesion at right posterior parietal region. On operation, Dura was tense and scanty subdural hematoma and massive brain swelling were identified and intracerebral hematoma estimated 80cc was evacuated. Atypical trophoblast was found microscopically from biopsy material. She died on the 2nd postoperative day.

The ever-growing traffic on the roads is one of the main causes of the rise in the number of head injured patients, fall and violence are also increasing constantly, so that more and more people are suffering from head injuries. These many present-day accidents frequently result in the victims receiving multiple complex injuries beside head injuries and the prognosis of such patients become unfavorable. For example, it is well, known that the combination of head injuries and chest injuries is hazardous. This paper is concerned with the problem of associated injuries , in 575 head injured patients admitted to Department of Neurosurgery, Kyung Hee University Hospital from January to December. in 1975. The results were as follows; 1) In head injured patients, males outnumbered females by almost 2 to 1. The age incidence was greatest in 3rd decade. 2) The head injuries were caused by traffic accident(72.8%), falls from heights (18.2%), direct blow(8.7%) and bullet injury(0.35%). 3). Significant associated injury was present in 24% of the total patients and the most frequent nature of the associated injuries was fracture. 4) The sites of the associated injuries were distributed as limbs(39. 7%.), chest (15.4%), pelvis(11.6%) and abdomen(8.5% in order. 5) Each, mortality rate of the associated injuries was as follows; 25.0% for abdomen, 24. 1% for chest and 13.6% for pelvis. 6) Overall mortality rate of head injured patients was 8.3%, in contrast, that of the patients with, associated injuries was 10.9%.

The precipitation samples were collected at a site in Cheju National University and investigated for the major ion components of them during the period of October, 1996 to May, 1997. During this period, the volume-weighted average value of pH was 5.09 and that of electric conductivity was 16.61μS/㎝, and the concentrations of ions were shown in the order of SO₄²?> Cl?> NO₃?>Na?> NH₄?> Ca²?> K?> Mg²?. For the precision of the analytical data, the correlation coefficient between the sum of the cation equivalent concentrations and that of the anion equivalent concentrations showed r²=0.8745 (r=0.940), and the correlation coefficient between the measured conductivity and the calculated conductivity was r²=0.9898, showing quite satisfactory agreement each other. Also, the correlation coefficient between the acid fraction from the equivalent concentrations of each ion and that from the measured pH and electric conductivity showed r²=0.9107. In the investigations of sea-salt effect, the enrichment factor of SO₄²?, Ca²?, K? was 9.1, 12.8, and 8.2, respectively, showing that most of these were coming to the air by the other factors rather than from seawater. On the other hand, it was found that the Cl? and Mg²? were mostly due to the origin of seawater. In the case of the effect of soil particulates, the enrichment factors of SO₄²?, Cl?, NO₃?, and NH₄? showed quite high values indicating suspending in the air through the other factors, however, some of Na?? and Mg²? and most of K? were found mainly due to the soil particulates. Moreover, for the effect on the pH of rainwater, the calculated neutralization factors of NH₄?, Ca²?, and Mg²? were 0.415, 0.274, and 0.101, respectively. It has shown that the hydrogen ions in the rain of Cheju city were neutralized about 52% by NH₃, and the Ca²? and Mg²? have neutralized them about 35%, and 13% respectively.

The increase in the prevalence of head injury amongst civilian population and the provision of adequate hospital services have become matters of world-wide concern. Many present-day accidents may result in the victims receiving multiple complex injuries beside head injuries and the prognosis may become unfavorable in these patinets. Therefore, the neurosurgeon must be alert to the possibility that his patients have injuries to areas outside the brain and be capable of rendering necessary, often lifesaving, treatment during the initial phase of management. We analysed associated injuries in 1523 head injured patients admitted to Department of Neurosurgery, Kyung Hee University Hospital from October, 1971 till September, 1977. The results were as follows; 1) The incidence of associated injury was 23.6% of all 1523 head injured patients. 2) In all head injuries, male outnumbered female by almost 2 to 1 and the ratio was similar in associated injury group (2.4 : 1). 3) The age distribution of all head injuries was 3rd, 1st and 4th decades in order, but in associated injury group it was 4th, 3rd and 5th decades in order. 4) Common causes of head injuries were traffic accidents (76.6%) and fall (11.6%), but in associated injury group traffic accident was the most frequent cause (90.8%). 5) The incidence of associated injury was higher in relation to the severity of head injury. 6) The sites of associated injuries were distributed as limbs, chest and face in order and the most frequent nature of associated injuries was fracture. 7) Single associated injury was more frequent than multiple, associated injury, about 5 to 1. 8) Overall mortality rate of all head injuries was 9.3% in contrast that of associate injuries was 17.5%. 9) Surgical mortality rate was significantly higher in associated group (40.3%) than nonassociated group (26.1%). 10) In multiple associated injuries the mortality rate was higher (21.3%) than in single associated, injury (16.4%). 11) Mortality rate according to associated injured sites was as follows; 36% for visceral injuries and 34.1% for chest injuries. 12) The mortality rate was highest in serious chest injuries such as hemo and/or pneumo-thorax and in hypovolemic shock on admission (60%).

뇌질환에 대한 CT 소견의 분석고찰

김예철,강영철,문석배,김국기,이봉암,이영근 대한신경외과학회 1978 Journal of Korean neurosurgical society Vol.7 No.2

Only a few years following its original development by the English Physicist G.N. Houns-field at 1971, cranial computed tomography has proved to be of revolutionary importance for the diagnosis of brain disorders. This is reflected not least by the almost immediate and worldwide acceptance of the diagnostic method. First in Korea, The EMI Scanner (CT 5005/7, 160×160 matrix) was introduced at Kyung Hee University Hospital on October 1977. Since then, we reviewed 444 CT scans for 1 year. 216 representative examples of abnormal CT findings among these have been chosen from this group of cases for more detailed discussion and illustration. The results were as follows; 1) 216 abnormal CT findings were subdivided into brain neoplasm 50, orbital tumor 6, AVM 1, intracerebral hemorrhage 44, occlusive CVD 30, craniocerebral trauma 46, cerebral abscess 3, meningoencephalitis 8, hydrocephalus 13, atrophy 16, parasite 4. 2) In most brain tumor cases the tissue undergoes a change of density. Vascularized tumors were enhanced after contrast infusion. Solid tumor area are well differentiated against cystic area and necroses, and hemorrhage in tumor is also well visualized. Tumor type is often surmised, exact classification is not possible. Thus a glioblastoma multiforme of the ring type can not lie differentiated from a metastatic tumor with central necrosis. But tumor density, appearance of contrast enhancement, predilection site of tumor, relation to adjacent structure, a degree of perifocal edema and clinical data are aid to identify the tumor type. 3) Spontaneous intracerebral hemorrhage can be identified with certainty because of high absorption values. Extent of hemorrhage and invasion of the ventricle are usually exactly visualized. Blood filling of basal cisterns and interhemispheric fissure is also well demonstrated. As opposed to spontaneous intracerebral hemorrhage, cerebral infarction shows as a region of low absorption values as early as 6 to 8 hours after ictus, which is often poorly defined with irregular borders and having mass effect during the 1st week thereafter. Sharper margins and more homogenous low density are developed 1 to 2 weeks after ictus and surrounding edema subsides with shrinking of hypodense area. Ipsilateral ventricular dilatation, homogenous low density area and sharp margins are usually found in older infarcts. 4) CT is the best method of assessing craniocerebral injuries. Since extravascular blood is set off by its high density and edematous tissue by its lower density from normal brain tissue, sequelae from injuries whose existence could only be suspected on account of the clinical symptoms but escaped detection regardless of the method used, can now be visualized directly in the CT. 5) Brain abscess has a charcateristics but non specific appearance as CT, consisting of a ring configuration of the abscess capsule which .shows marked enhancement after injection of contrast material. In acute stage of the meningoencephalitis, routine CT scan may be normal. During the course of illness, diffuse enhancement of the basal cisterns and varying degree of ventricular dilatation may be found. 6) Brain atrophy is diagnosed by an enlargement of internal and external CSF spaces. Using standard sections a classifications of the grade and form of the atrophy is made. The diagnosis of cysticercosis is made primarily calcification and multiple solid dense mass or cystic lesion surrounded by edema which may become enhanced following infusion of contrast media.

Computed tomography (CT) is a new and innovative radiologic technique, the diagnostic value of which has been well established by many reports. On account of its rapidity and non-invasiveness, CT has become the diagnostic procedure of choice for the initial evaluation of head trauma patients. The authors have performed CT scan Eusing EMI-5005 on 5 cases of subdural hematoma during the period of 8 months from October 1977 to May 1978 at the Department of Neurosurgery, Kyung Hee University Hospital. Various attenuation coefficients of hematoma such as hyperdense, hypodense, isodense and of mixed density were observed by the CT images. One case of isodensity hematoma were clearly identifiable by delayed enhancement technique, which had been confused by ordinary, noninfused method.
