This is the report of a study carried out during the months of April to July in 1974, on the fisheries in regard to its labor management. At here the word of adjacent seas fisheries in Korea denotes the fisheries carried out by fishing boats for one or two boats trawling, purse seinning, shrimp trawling, and whale catching. For the objective of this above study the auther randomly selected 257 crew-members for the questionaires and direct interviews and, with this method, proceeded surveys and investigations on the following factors such as the organization and its functions, personel administration in regard to placement and merit system, regulations and rules of working, wages and salaries, welfare facilities or considerations, safety and sanitation, human relations within organization and cooperation, and thus covered the whole important factors with the modern management system. The results of the studies are; The factors above the standard level are only on those of organization and functions, merit system and placement and human relations and for the rest the judgement are to be laid as below the standard level. And particularly revealing the problems on the following factors; 1) Wages and salary particulary on the payment upon laid out, and the payment of wages in advance. 2) Welfare facilities such as of the insurance and crew members' welfare for the good use of leisure time. 3) Placement and merit system in regard to ite method of appointing or empioying 4) Regulations and rules of working in regard to the vacation or leave of absence. 5) Safety problem particularly on the matter of sanitation or hygene. 6) Coopertion on the matter of participation on the interested problems on both parties. The above points indicated are, methinks, all derived out of the out dated method of management. Therefore, for the improvement of the labor management, first of all, nothing is more urgent than to adopt the modern labor management method as well as to encourage and enlighten the social responsibilities burdened on the enterprise.

Glycyrrhiza uralensis Fischer is one of the most commonly used herbs. Recently, the stem and leave of the plant have been interested in physiological activities because the aerial parts have been thrown away. Finding out cultivation method of Glycyrrhiza uralensis Fischer to improve chemical ingredients and biological activities has been tried these days. In this study, different wavelengths of light emitting diode (LED) were used for a cultivation of Glycyrrhiza uralensis Fischer. Antioxidant activities and inhibitory effect on mutagenecity of samples were evaluated. The stem and leave cultivated under blue light (BL-0) showed the strongest antioxidant activities of $3.02{\pm}0.13{\mu}g/ml$ ($EC_{50}$) and $2.18{\pm}0.18{\mu}g/ml$ ($EC_{50}$) in DPPH and ABTS radical scavenging test, respectively. Total phenolic content of BL-0 was $2.93{\pm}0.11g/100g$, the highest value between cultivation conditions. However, antioxidant activities of the stem and leave cultivated under red light were the weakest between samples. All of the stem and leave used in this study showed inhibitory effect on mutagenecity of 1-nitropyrene. BL-0 showed stronger inhibitory effects on mutagenicity of Trp-P-1, Trp-P-2, and AFB1 than samples cultivated under other conditions. Only on mutagenecity of 2-aminoanthracene, the stem and leave cultivated at 1 m apart from red light (RL-1) showed the strongest inhibitory effect. These results indicate that blue LED might be the most effective condition for improvement of physiological activities for the aerial parts of Glycyrrhiza uralensis Fischer in cultivation. The components were identified with GC/MS. Cytidine was detected only in RL-1 at 25 min of retention time and 2-bromotrimethylene glycol was detected only in BL-0 at 37 min.
A field experiment was conducted to evaluate effect by split-application of slow-release fertilizer on the tea plant. The yield of the 2nd harvested tea leaves was not different to the slow-release fertilizer of two time split manuring had been doing Sep. or Mar. compared with the traditional manuring had been doing four time split manuring, but that of the slow-release fertilizer to one time split manuring in Sep. had decreased $12.5{\pm}1.5%$. In case of the 2nd harvested leave, the contents of chemical components related to quality such as total nitrogen, total amino acid were somewhat higher in the slow-release fertilizer (two time split manuring) than in the traditional manuring, but those of tannin, and caffeine were low, and those of chlorophyll, vitamin C, free sugar and theanine were not different to out of treatments. In scoring test, appearance and quality of green tea were more excellence in the two time split manuring compared with one time split manuring of slow-release fertilizer and with the traditional manuring (four time split manuring). Therefore, I thought that use of slow-release fertilizer be increased yield and quality of tea leaves, and improved efficiency nature of nitrogen, phosphate and potassium out of soil fertilizer components.
Using grounded theory method, this study analyzed the in-depth interviews with 11 parents of institutionalized children in order to find out how the experience of the parents on the process of the children's family reunification. According to the results, it was 'leaving one's child' that composed causal conditions, and also it was 'sentenced life' and 'adapting to a life without child' that composed existing conditions. Thus, the contextual condition was found out as 'a belief of family' and 'a belief of child caring' and the mediation conditions were 'power to recover' and 'not being as one's intentions'. Also, reaction/interaction strategies turned out as 'preparing a basis of child-care', 'playing a parent', 'standing against being adapted' and 'adjusting as their children back to family'. Finally, the analysis showed 'burdens on caring', 'wanting to leave one' child again', 'having stronger family membership' and 'being hopeful in a future' as results. The specific levels of the process were found out as following 4 steps, as time goes by. 1)Fostering children at institutions: become harsh parents(or a harsh parent), 2)After fostering: rebuild collapsed family in order to take the children back, 3)Family reunification: become aboveboard to oneself, family and the world, 4)After family reunification: try to keep the family taking precautions against resending. While taking their children back, the parents turned out to experience long, unremitting tension. Reflecting results of the analysis above, and in order to promote sending institutionalized children back to their families this article suggests practical alternatives for parents who left their children in institutions.
Arbitration is one of alternative dispute resolution systems which settle a dispute by arbitrators(private persons) based on a contract between contracting parties without a judicial litigation system involved. As a valid arbitration agreement is an essential requirement for commencement of arbitration, the first thing to be determined is whether there is a valid arbitration agreement or not when a dispute is submitted. A consumer arbitration agreement usually exists as an arbitration clause in an adhesive contract between consumers and a seller. When consumers buy a product from a seller, they are requested to agree on a general terms and conditions which are unilaterally drafted by a seller in advance. These terms and conditions are not negotiable because it is an adhesive contract and consumers are placed in "take-it-or-leave-it" position. Therefore, even though there is an arbitration agreement between consumers and a seller, it has to be carefully considered whether it has a legal effect or not. In this respect, a court will examine if an arbitration agreement has procedural unconscionability and substantive unconscionability. Therefore, as U.S is a well-advanced and arbitration-friendly country, this paper analyzes four U.S cases to find out (i) what a court considers, (ii) how a court examines and interprets procedural and substantive unconscionability and (iii) if there has been a change in regard to a court's decision. By doing so, it will provide some suggestions and guidelines for a consumer arbitration in Korea.
Safety service improvement and development of efficient maintenance strategies for corroded steel structures are undeniably essential. Therefore, understanding the influence of damage caused by corrosion on the remaining load-carrying capacities such as tensile strength is required. In this study, artificial neural network (ANN) approach is proposed in order to produce a simple, accurate, and inexpensive method developed by using tensile test results, material properties and finite element method (FEM) results to train the ANN model. Initially in reproducing corroded model process, FEM was used to obtain tensile strength of artificial corroded plates, for which surface is developed by a spatial autocorrelation model. By using the corroded surface data and material properties as input data, with tensile strength as the output data, the ANN model could be trained. The accuracy of the ANN result was then verified by using leave-one-out cross-validation (LOOCV). As a result, it was confirmed that the accuracy of the ANN approach and the final output equation was developed for predicting tensile strength without tensile test results and FEM in further work. Though previous studies have been conducted, the accuracy results are still lower than the proposed ANN approach. Hence, the proposed ANN model now enables us to have a simple, rapid, and inexpensive method to predict residual tensile strength more accurately due to corrosion in steel structures.
Variable selection k nearest neighbor QSAR modeling approach was applied to a data set of 80 3-arylisoquinolines exhibiting cytotoxicity against human lung tumor cell line (A-549). All compounds were characterized with molecular topology descriptors calculated with the MolconnZ program. Seven compounds were randomly selected from the original dataset and used as an external validation set. The remaining subset of 73 compounds was divided into multiple training (56 to 61 compounds) and test (17 to 12 compounds) sets using a chemical diversity sampling method developed in this group. Highly predictive models characterized by the leave-one out cross-validated $R^2$ ($q^2$) values greater than 0.8 for the training sets and $R^2$ values greater than 0.7 for the test sets have been obtained. The robustness of models was confirmed by the Y-randomization test: all models built using training sets with randomly shuffled activities were characterized by low $q^2{\leq}0.26$ and $R^2{\leq}0.22$ for training and test sets, respectively. Twelve best models (with the highest values of both $q^2$ and $R^2$) predicted the activities of the external validation set of seven compounds with $R^2$ ranging from 0.71 to 0.93.
Sam Shepard is one of the leading American playwrights who represented Off-Off Broadway in the l960s and 1970s. In his early days, he wrote many experimental plays but later he turned to realism. However, under the superficial realism in his later plays, we find that they contain experimental devices and themes. True West (1980) is the last play of ills realistic family trilogy. This play shows that the tradition of Old West, which is symbolized and replaced by desert, disappeared in the industrialized clues of modern West. The Old West is compared which the modern West through the struggle of two brothers, Lee and Austin. Their father, 'Old Man', ran out on his family and went to the desert but did not succeed there. He shows that he failed in achieving the American Dream. The family appears unusual and demolished The relationships of the characters are not based on love and belief. The family symbolizes the negative aspects of modern American society. After Austin recognizes the actual situation finding that there is no real life in the modern West, he tries to leave the city and his family. He wants to go to the desert in search of a new life. However, in the last tableau Lee blocks the exit and the two brothers square off. It implies that they are doomed to continue their struggle. The message Implies that American society today is lacking the same positive values they once had in the Old West.
We investigated the structure-activity relationships on use of multi-layer neural networks. The relationships are techniques required in developments of medicines. Since many kinds of observations might be adopted on the techniques, we discussed some points between the observations and the properties of multi-layer neural networks. In the structure-activity relationships, an important property is not that standard deviations are nearly equal to zero for observed physiological activity, but prediction ability for unknown medicines. Since we adopted non-linear approximation, the function to represent the activity can be defined by observations; therefore, we believe that the standard deviations have not significance. The function was examined by "leave-one-out" method, which was originally introduced for the multi-regression analysis. In the linear approximation, the examination is significance, however, we believe that the method is inappropriate in case of nonlinear fitting as neural networks; therefore, we derived a new index fer the relationships from the differential of information propagation in the neural network. By using the index, we discussed physiological activity of an anti-cancer medicine, Mitomycine derivatives. The neuro-computing suggests that there is no direction to extend the anti-cancer activity of Mitomycine, which is close to the trend of anticancer developing.
Spatial prediction methods have been useful to determine the variability of water quality in space and time due to difficulties in collecting spatial data across extensive spaces such as watershed. This study compares two kriging methods in predicting BOD concentration on the unmonitored sites in the Geum River Watershed and to assess its predictive performance by leave-one-out cross validation. This study has shown that cokriging method can make better predictions of BOD concentration than ordinary kriging method across the Geum River Watershed. Challenges for the application of cokriging on the spatial prediction of surface water quality involve the comparison of network-distance-based relationship and euclidean-distance-based relationship for the improvement in the predictive performance.
