Since 1982, female agricultural workers are populous than male in Korea. Previous study was suggested that female workers are more sensitive to the agricultural medicine poisoning than male. This study was conducted with the aim of evaluating the impact on plasma components and nutrient intakes in female agricultural workers by the use of pesticides. Data were obtained from 44 females residing in Wonjoo, Kangwon-do area. Analysis for the general characteristics, nutrient intakes, and plasma components of the subjects were performed by physical examination, 24-hour recall method and venous blood sampling. They were divided into 3 groups according to the degree of the pesticide use: 8 in none(Non-expose group), 14 in low(<4/yr)(Low-expose group), and 22 in high$({\geq}4/yr)$(High-expose group). The results are summarized as follows. Serum glucose, SGOT, SGPT, triglyceride, HDL-cholesterol did not correlated with pesticide use and were not different among the groups. But serum total cholesterol was higher in pesticide use group. With increasing the number of pesticide use times, leukocyte count was tended to increased. Eighty two percent of the subjects were hemoglobin less than or equal to 12g/dl. Hematocrit, MCV, MCH, MCHC, serum Fe, Serum ferritin belonged to normal range and did not correlated with pesticide use. Intake of energy, Fe, vitamin $B_2$ were lower than RDA. Fe, K, and vitamin A intake were higher in don't use group than the other groups. There are not many differences according to using the pesticide in anthropometric measurements, nutrient intakes, and blood components, except for serum total cholesterol level and some nutrients intake. But these results suggest the need the systemic researches about the effects the pesticide using on nutritional status in Korean agricultural workers.

For understanding skin temperature based on clothing design from a viewpoint of comfortable wearing, the skin temperature, physiological reactions(body temperature, blood pressure and pulse) and physilolgical response(thermal sensation, comfort sensation and perceptive sweaty sensation) were measured on condition tha t5 naked healthy male exposed to serveral environmental temperatures,( $20{\pm}1.0^{\circ}C$ ,$28{\pm}1.0^{\circ}C$ and $32{\pm}1.0^{\circ}C$). As the results of this testing, the regional skin temperature was varied for 90min just after expose to those the environment but was generally stabilized for the nest 90min. It was proved the difference of the regional skin temperature at low temperature environmental($20{\pm}1.0^{\circ}C$) was larger than at high temperature environmental($32{\pm}1.0^{\circ}C$) and inder serveral environmental temperature,the degree of the regional skin was not equal. Except in case of the thigh, the front of all regional skin temperature turned out higher than the back of them. According to change of environmental temperature, body temperature and pulse were altered. In the pshycological response, 'thermal sensation-comfort sensation' was felt to 'slightly warm - comfortable' at $28{\pm}1.0^{\circ}C$of the environmental temperature, and 'perceptive sweaty sensation', wneh it was said 'sweat' at only $32{\pm}1.0^{\circ}C$ of it.

This paper presents a new algorithm for the K shortest paths Problem which develops initial K shortest paths, and repeat to expose hidden shortest paths with dual approach and to replace the longest path in the present K paths. The initial solution comprises K shortest paths among shortest paths to traverse each arc in a Double Shortest Arborescence which is made from bidirectional Dijkstra algorithm. When a crossing node that have two or more inward arcs is found at least three time by turns in this K shortest paths, there may be some hidden paths which are shorter than present k-th path. To expose a hidden shortest path, one inward arc of this crossing node is chose by means of minimum detouring distance calculated with dual variables, and then the hidden shortest path is exposed with joining a detouring subpath from source to this inward arc and a spur of a feasible path from this crossing node to sink. If this exposed path is shorter than the k-th path, the exposed path replaces the k-th path. This algorithm requires worst case time complexity of O(Kn$^2$), and O(n$^2$) in the case k$\leq$3.

The purpose of our study was to determine the entrance surface dose and absorbed dose in ovary when using the metal speculum and plastic speculum in hysterosalpingography respectively. The examinations was performed in anthropomorphic phantom into which calibrated photoluminescence glass dosimeter were placed on symphysis pubis level surface and ovary area. We checked average fluoroscopy time and spot expose times during the hysterosalpingography. It was average fluoroscopy time 58 sec, spot expose 5 times. We divided the subjects into two different groups to used metal and plastic speculum. We measured 10 times of absorbed dose in the same condition of the anthropomorphic phantom. We compared two groups adsorbed dose on ovary with speculum material-related. The entrance surface dose on of plastic Speculum using group was average 17.23 mGy, absorbed dose on ovary was average 3.51 mGy. The entrance surface dose on ovary of metal Speculum using group was average 19.95 mGy, absorbed dose on ovary was average 4.14 mGy. Plastic speculum using group shows a decrease absorbed dose(17.9%) as compared with metal speculum using group. The method of plastic speculum using in hysterosalpingography. might provide us with lower radiation dose, especially in patients with childbearing stage.
