모듈러 주택은 많은 장점이 있음에도 불구하고, RC구조에 익숙한 소비자들의 모듈러 주택에 대한 낮은 선호도가 모듈러 주택의 높은 공사비를 초래하고 있다. 모듈러 건축물의 공사비는 RC 구조 대비 130% 전후로 형성되어 있어 모듈러 건축물의 경제성 확보가 시급하다. 따라서 본 연구에서는 모듈러 주택의 공종별 절감가능 금액을 산출한 후, 장기적 관점에서의 경제성 분석을 진행하였다. 연구 진행을 위해 모듈러 주택의 내역서를 공장제작분 및 현장설치분으로 분개하여 공종별 발생하는 재료비, 노무비, 경비를 비교 분석을 진행했다. 그 후 파레토도를 작성하여 비용 누계 80% 내외에 포함되는 핵심 공종을 찾아 공사비 절감 가능대상으로 선정하였다. 국내 모듈러 건축의 시장규모가 일본, 유럽 국가 등 모듈러 선진국 수준과 비슷하다는 가정하에 전문가 인터뷰를 통해 모듈러 공법의 특성을 반영한 비용절감 방법을 설정하였고, 모듈러 업체 전문가를 대상으로 한 설문조사를 통해 비용절감 방법을 적용했을 때의 공종별 절감 가능 금액을 산출하고, 총 절감가능 금액을 산출했다. 비용절감 방법 중 '자동화 및 기계화'방법을 적용했을 때의 절감가능성이 1.54%로 가장 큰 것을 알 수 있었고, 국내 모듈러 생산 과정이 전자동화 및 기계화가 된다면 공사비 절감 뿐만 아니라 공기 단축도 기대해 볼 수 있다고 판단한다.

월동수조류의 군집에 영향을 미치는 환경요인을 파악하기 위하여 원주천을 6구간으로 나누어 조류의 군집 및 하천의 크기, 기온, 수질, 저서성무척추동물, 어류를 조사하였다. 원주천에서 수조류의 군집에 영향을 미치는 요인은 하천의 구조 및 기온, 수질이었다. 하천의 구조 중 월동수조류의 군집에 가장 큰 영향을 미치는 요인은 저수로의 폭과 흐르는 물의 넓이인 유폭으로 그 넓이가 넓을수록 월동수조류의 종수와 개체수가 많았으며, 둔치의 폭이 넓어서 저수로의 폭과 유폭이 좁아질수록 개체수는 적었다. 월동기의 기온 변화는 하천의 결빙으로 이어지므로 수조류의 군집에 영향을 미쳤으며 결빙되지 않는 구간은 기온의 하강과 상승에 뚜렷한 증가와 감소를 보였다. 수질조사 항목 중 pH, 수온, COD, BOD, T-N, T-P, 총대장균의 수치는 하류로 갈수록 증가하여 월동수조류의 개체수 증가와 높은 상관성을 보였는데 하류에 위치한 하수처리장의 영향으로 S6의 수질검사 항목의 수치가 높게 나타났으며 월동수조류의 개체수 또한 가장 많이 관찰되었다. 하수처리장 배출수는 수질에 상당한 영향을 미치는 것으로 보이는데 T-N을 비롯하여 여러 항목 수치의 증가는 하천의 영양화를 촉진시키고 이로 인해 유기물질의 축적과 수서생물의 증식을 가져옴으로 이를 먹이원으로 하는 월동수조류의 증가 원인이 될 수 있을 것으로도 여겨진다. 저서성 대형무척추동물의 군집과 어류의 군집은 원주천 모든 구간에서 대체적으로 양호한 것으로 나타났으나 월동수조류의 군집과의 상관성을 보이지 않았다.

This study was conducted to investigate the physical and chemical properties of soils in Saemangeum reclaimed lands. The investigated areas were total 5,020 ha which included 220 ha for Agricultural Life site, 2,450 ha for Tourism & Leisure site, 1,130 ha for Industrial & Research site, 820 ha for Bioenergy crop production site, and 400 ha for Rural City site. Soil samples consisting of the upper 20 cm from the surface were collected in every $200m{\times}500m$ of the each site in March and September, 2015. Particle size distribution of soils in the reclaimed land was 83.2% sand, 8.6% silt and 8.2% clay in average. Soil texture was distributed as 40.8% sandy soil, 35.5% loamy sand, and 19.7% sandy loam. Based on the investigation of soil chemical properties conducted in March, 2015, soil pH, electrical conductivity of a saturated soil paste extract (ECe), and exchangeable (Exch.) $K^+$ and $Mg^{2+}$ concentrations were higher than those of the optimum levels for upland soil, whereas soil organic matter content, available (Avail.) phosphate concentration, and Exch. $Ca^{2+}$ concentration were lower than those of the optimum ranges. Depending on the results of the soil chemical properties measured in September, 2015, soil pH, ECe, and Exch. $K^+$ concentration were higher than those of the optimum levels, but soil organic matter, Avail. phosphate, and Exch. $Ca^{2+}$ concentration were lower than the optimum ranges. In addition, distribution of sodic soil ranged between 41.4% and 50.0%, and saline soils were from 16.4 to 31.8%. Soils with pH values above 7.0 increased from 15.3% in March to 35.2% in September. Soils with ECe values over $4.8dS\;m^{-1}$ increased from 45.6% to 50.7%, whereas soils with the values below $2.0dS\;m^{-1}$ decreased from 42.8% to 36.9%.

The purpose of this study is to examine the changing process of the collective housing in Korea; focusing on the alteration process of the apartment housing, which became a representative housing type in Korea, nowadays. The alteration process of the apartment housing in Korea can be divided into three stages: the introduction stage, the trial stage and the settled stage. The introduction stage is the period between 1920, when the collective-housing buildings were constructed in Korea for the first time, and the Liberation of Korea(1945). The trial stage is the period between 1945 and 1975. During this period, common housing has been constructed. And the massive apartment buildings were started to be supplied after 1975. The settled stage is the period between 1975 and the present. The main scope of this study will be the introduction and trial stages, since a lot of in-depth studies have been executed on the settled stage. The history of the collective housing of Korea starts with City Housing of Seoul, in 1921. It is guessed that this housing was to be small-sized and row-housing type. The first-built, apartment-type building, in Korea, was Mikuni Apartment House, which was constructed as a boarding room of Mikuni Company. In the introduction stage, apartment buildings were built by Japanese architects, with Japanese housing style. Most of them were planned in dormitory type, and some of them were run as tenant houses. Most of them were constructed by bricks, but sometimes by timbers. Tadami was laid in every room and inside-corridor was located in the middle of the house. Although the major style of the apartment buildings was Japanese, the Korean dwellers of those apartments has been influencing the housing type of them. In the trial stage, apartment housing has been experienced in diverse ways. With the development of building technology, floor heating system was settled in apartment housing. This improved the amenities of apartment dwelling remarkably. Although some heterogeneous characteristics still remained in the apartments of Korea, in terms of housing style, the housing style of apartments has been changed into own style of Korea, in accordance with Korean people's life style. The results of this study give us some good implications regarding contemporary housing plan: First, if the unit size of a collective housing is small, the more space could be available for community activities. Second, when planning of collective housing, more concerns should be payed on surroundings. Third, more attention should be payed about low-rise apartment housing, and more land-friendly planning would be required.

This study is to survey the materials purchasing and inventory management status and the characteristics and opinions of the staff in charge of purchasing and inventory of the general hospitals in Busan area in order to contribute to the rationalization of its management through the grasp of actual situation and the presentation of desirable improvement plan for the materials purchasing and inventory management. The status of medical institute had been surveyed by the purchasing/ administration managers of total 26 general hospitals, and the purchasing/ management questionnaires had been commenced with 86 staff of the 26 hospitals. Its major survey results, after the analysis of 24 medical institute statuses (return rate of 92.30%) and 60 staff questionnaires (return rate of 69.76%), are as follows. First, post-purchasing evaluation system is not used actively, orders are being placed by phone or fax, and general merchandise is being purchased through free contracts in most of the hospitals participated in the survey. Second, as per the materials supplying methods, the requisition and delivery system is currently the most popular in the hospitals surveyed, however, both the requisition and delivery system and the par level transfer system are the most desired in the hospitals of more than 500 beds, and the par level transfer system is the most desired in the hospitals under 500 beds for the materials supplying system in the future. Third, as per the inventory management system that is desired the most in the future, the SPD and JIT types are preferred in the hospitals of more than 500 beds, the stockless strategy is preferred in the hospitals under 500 beds, the senior staff above section chief grade prefer the stockless strategy, and the junior staff prefer the ABC classification and SPD types. Fourth, The necessity of purchasing staff's training for the materials management is highly recognized but the effectiveness is not so much acknowledged, which is because such a training is thought to be so superficial and formal that it is not helpful much in the actual field. When summarizing the survey results as above, the materials purchasing and management system is differed for each group of hospitals according to the size of beds, and the more scientific management system is largely required by the general hospitals in Busan city. They also hope the introduction of joint purchasing system, materials management by the bar-code system, and positive execution of the market survey and training of the relevant staff for the management of purchasing affairs. So the more systematic purchasing and inventory management is regarded to be necessary through the introduction of scientific and specialized education of materials management, market survey, and post-purchasing evaluation system also through the computerization of materials purchasing and inventory management as soon as possible.

It has been contributed to public health that the hospital has multiplied in the aspect of number and has been a large size with development of modern medical science, meanwhile the problem of hospital infection is coming out seriously. Respiratory hospital infection among hospital infections develops, very commonly from patients having taken the operation of intubation or tracheostomy, which results from a big factor that the infection developed from medical appliances used for respiration aids, contamination of solution and infection of medical staff. This study is separated into four steps-the time to use normal saline and distillation water for storaging catheter which are the cause of the infection of solution to store distillation water and catheter, not to say the catheter used when the patient who should get tracheostomy operation takes suction. The purpose of this study is to offer the basic data which are needed to check contamination degree as time goes by and nurse intervention and grope for a new nursing intervention. The target of this study is hospitalized 1D an intensive care unit having 700 sickbeds which is located in IKSAN city and it targeted patients before 7 days passed after an operaion of a tracheostormy. Materials collected were analyzed by SPSS PC+ figures program. The result of this study were as follows ; 1. The gradual contamination levels of the normal saline used In suction are showing that colony increase in proportion to the length of time. 2. while colony increases in normal saline with the lapse of time. distillation water mixed with 5cc of potadine did not show any sign of the formation of colony from its preparation until it was used for 8 hours. 3. Such variables as the period of intubation insertion. the length of hospitalization in I.C.U. the age and the level of contamination of normal saline have no inter-relationship. Therefore. as the length of normal saline used In suction. the contamination level increases with the excelleration of the contamination speed. 4. Regarding the number of suction and the contamination level of the normal saline. We can observe correlation contamination level in the 3 step of suction(mean value:13.4) and the saline which was used for one hours(r=0.702. P=0.00l). four hours(r=0.694. P=0.00l). eight hours(r=0.488. P=0.029). Further we can observe contamination in the 4 step of suction (mean value: 17 .8) well as saline used for eight hours; [for one hours (r=0.64l. P=0.002). four hours (r=0.670. P=0.00l). eight hours (r=0.57 4. P=0.008)]. Thesedays clinics use normal saline by changing it. three times a day. however. the timing of saline change and the current suction methoed should be changed given the one hour used normal saline contamination number 79.850. Regarding the number of suction and the contamination lend of the normal saline.
