Soybean (Glycine max (L.) Merr.) is a representative food resource. To preserve the integrity of soybean, it is necessary to protect soybean yield and seed quality from threats of various pests and diseases. Riptortus pedestris is a well-known insect pest that causes the greatest loss of soybean yield in South Korea. This pest not only directly reduces yields but also causes disorders and diseases in plant growth. Unfortunately, no resistant soybean resources have been reported. Therefore, it is necessary to identify the distribution and movement of Riptortus pedestris at an early stage to reduce the damage caused by insect pests. Conventionally, the human eye has performed the diagnosis of agronomic traits related to pest outbreaks. However, due to human vision's subjectivity and impermanence, it is time-consuming, requires the assistance of specialists, and is labor-intensive. Therefore, the responses and behavior patterns of Riptortus pedestris to the scent of mixture R were visualized with a 3D model through the perspective of artificial intelligence. The movement patterns of Riptortus pedestris was analyzed by using time-series image data. In addition, classification was performed through visual analysis based on a deep learning model. In the object tracking, implemented using the YOLO series model, the path of the movement of pests shows a negative reaction to a mixture Rina video scene. As a result of 3D modeling using the x, y, and z-axis of the tracked objects, 80% of the subjects showed behavioral patterns consistent with the treatment of mixture R. In addition, these studies are being conducted in the soybean field and it will be possible to preserve the yield of soybeans through the application of a pest control platform to the early stage of soybeans.

The purpose of this study was to find out physical and emotional status, and nursing needs of the pregnant women who were hospitalized by premature labor. The research respondents were 96 from four university hospitals located in Seoul, from June 30, 1996 to September 15, 1995. The research instrument was consisted of 14 items of physical status(discomforts) (Cronbach's=0.86), 17 items of emotional status (Cronbach's=0.89), 33 items of nursing needs (Cronbach's=0.94), and they were measured by 5 level of Likert Scale. The data were analyzed by frequency, percentage, mean standard deviation, ANOVA, Pearson correlation coefficient as the statistical techniques in the program of SPSS/$PC^+$. The findings were as follows : 1. The perception of physical status was mainly about physicl discomforts during the hospital stay. It included four categories about 'absolute bed rest' 3.48, 'hospital foods' 3.38, 'health care teams' 2.93, 'hospital environment' 2.83 in order of mean of discomforts. The most discomfortable one was "malodor by not doing personal hygiene." The next one was "urination and defecation on the bed using bedpan." 2. The perception of the emotional status was about negative mood related to 'fetus', 'hospitalization' perse, 'personal situation.' The highest score of negative mood was "I am afraid that the baby's condition will be bad if I deliver it before full term." The next one was "I am anxious about whether my baby will be in incubator if I deliver it before full term." 3. The highest mean score among items of nursing needs was "Nurses observe whether the labor come or not with concerns." The next one was "Nurses observe the fetal movement and check up the fetal heart sound." The lowest one was "Nurses help me when I need bedpan." 4. Nursing needs were consisted of four categories : professional, educational, emotional, and physical. The mean score of them was high in professional, educational, emotional, and physical need in order. 5. The physical status was related to "Experience of treatment for maintenance of pregnancy" and "Experience of hospitalization by premature labor". The emotional status was related to "Type of delivery" and "Type of habitation." 6. In the correlation of physical and emotional status, it showed positive correlation between them. The higher score of physical discomfort, the higher score of negative mood(r=0.5113, p=0.0001).

The purpose of this study is to define the effects of the roles played by the Doulas : one group educated on the conventional Lamaze method known to have effects on birth pang during delivery process and the other group educated both on Lamaze and therapeutic touch. On the various factors of delivery, and thereby, provide for some basic data to develop an effective nursing intervention to relieve women of their birth pang. 136 mothers who were hospitalized in a general hospital from June 13, 1998 to May 13, 1998 to May 13, 1999 to deliver their first babies were sampled to be divided into control group, test group I and test group II and thus be subject to interviews and observations. As for the tool of study, melzack's(1975) 'pain scale', McCaffery's(1972) and Mcrachlan's(1974) 'pain expression scales' and Spielberger's (1975) 'anxiety scale' were used. The preparatory educational programs consisted of 5week Lamaze method and therapeutic touch. The research, design was quasi-experimental, non equivalent, posttest only control group design. The collected data were processed using the SPSS/PC statistics software for frequencies, means and one-way Anova as well as Tukey HSD and Scheffe test as post hoc for individual comparison. Moreover, chi-square test was used to test the differences between groups, while Pearson's correlation coefficients were analyzed to determine the correlations between anxiety and variables. The findings are as follows ; 1. The birth pain of the mothers delivering first babies scored in a subjective and objective pain scale; 1) There was a significant difference of subjective birth pain at 8~10cm opening of cervix between control group and two test groups. 2) There was no significant difference of objective birth pain as per opening of cervex among three groups in terms of sweating, facial movement, bodily posture and vocal changes. 2. There was no significant difference of trait anxiety among three groups. however, there was a significant difference of state anxiety during labor process between control group and two test groups. On the other hand, all the three groups showed a significantly lower level of anxiety during labor process than when they were carried to the hospital. 3. There was a significant difference of the time of total and first-stage labor among three groups, while there was a significant but small difference of the time elapsed from 8~10cm cervix open to the full among three groups. 4. Two test groups showed a higher frequency of natural deliveries than the control group. 5. Two test groups were subject to these drugs than the control group. In conclusion, it was found that the test group I and II showed a shorter delivery time than the control group, a higher frequency of natural delivery and a lesser use of anodyne or epidural. In particular, this study is significant to develop a nursing intervention service or a therapeutic touch which the nursing administrators can apply to their hospitals in marketing programs.

In this paper, a method of disassembly time evaluation for a product has been proposed. The product designer can predict the ability of disassembly for a given product in terms of time by considering a type, size, weight, connection parts, and the movement distance of the product. The equation for calculating disassembly time were derived by applying the basis motion status of worker and some informations of connection parts, various tools, and many different type of assembly structures. The developed method of evaluating disassembly time has been applied to disassemble the product by manual labor. The proposed method has shown that the actual disassembly time was well predicted.

노조가입 결정요인을 횡단면 분석한 결과 한국에서 노조가입은 노동자 개인의 노조가입의사(수요 측면)가 아닌 노조가입 가능성(공급 측면)에 주로 좌우되고, 노조 유무는 기업체 규모와 밀접한 상관관계를 가지고 있다. 직무 만족도는 무노조기업 노조가입의사에는 통계적으로 유의미한 영향을 미치지만, 노조가입에는 유의미한 영향을 미치지 않는다. 앞으로 노조 조직률을 제고하려면 노조가입 가능성을 확대해야 하며, 이를 위해서는 제도적 요인과 행위주체 요인을 중시해야 한다.

본 연구에서는 소득과 소비의 불평등을 비교하고, 소득과 소비의 상호 연계에 있어서 항상소득가설의 역할을 분석하였다. 1990년 이후 소득 불평등도는 계속 심화되는 추세를 보였으나, 소비의 불평등도는 2000년대 초반까지 오히려 완화되다가 이후 소득의 불평등도와 동행하는 양상을 보이고 있다. 이는 2000년대 초반 이후 소비에 대한 제약이 충분히 완화되어 우리나라 가구의 소비가 항상소득에 의해 결정되는 양상이 정착되고 있음을 반영하는 것으로 판단된다. 결과적으로 2003년 이후 소비와 소득의 불평등도가 동행하는 양상은 소득의 불평등도 변화에 있어서 항상적 요인의 불평등도가 변동하고 있음을 의미하는 것으로 평가된다.

The purpose of this study is to analyze the technical efficiency and its determinants for Korean Apiculture farming by using from door to door and e-mail inquiry data. The analysis was implemented through the Cobb-Douglas stochastic frontier production function (SFPF) model including the technical inefficiency effect model for cross-sectional data. To measure the SFPF model, honey production was used for a dependent variable, and for input variables labor cost, preventive cost, material cost, feeding cost, depreciation cost were used. Farmer's age, farmer's career, farming scale, full-time or half-time firm and movement or fixed firm variables were used to measure the inefficiency effect model. The average technical efficiency on apiculture farming in Korea is estimated to be 0.8112. It means that there were technical inefficiency of about 18.88% in Korea apiculture farming. In this study there are some suggestions which could increase the technical efficiency of Korean apiculture farming.

Study was made for the work study application in industry by sampling one thousand manufacturing companies. Small and medium industries are far behind in systematic application of the work study technique. Large industries are gradually introducing the work study technique systematically in line with the nation-wide quality control movement. Major sessions that the industries feel important in IE curriculum were QC, Work study and Cost accounting followed by the Organization theory, Industrial psychology, and Labor relations. Most of the industries were still less aware of the sophisticated fields such as OR, SE and Simulation. They put more emphasis on QC and TQC and as a result, work study should be closely bounded to TQC in order to systemize the work study application in the future.
