Recently consumption of agrochemicals rapidly increased with the demand for higher crop productivity. With this trend the role of government control over the field efficiency and safety aspects of pesticide use became more important. The government reformed the pesticides approval and management scheme in 1977. The new act became effective from April 1 1978. This paper introduces the contents of new act and the methods of herbicide registration trial

Background : Electrolarynx, Esophageal voice, and Silicone voice prosthesis with tracheoesophageal(T-E) fistula have been used as vocal rehabilitating methods for the post-laryngectomized patients. Prosthetic rehabilitation of voice after total laryngectomy has gained wide acceptance and has become a common practice in many clinics since the pioneering works of Singer and Blom In 1979. Since the introduction of tracheo-esophageal puncture and application of Blom Singer$\circledR$ voice prosthesis in 1980, several reliable voice prostheses have been developed and are successfully being used. Objectives : Even though quality of voice produced by Silicone voice prosthesis with T-E fistula is superior to other modalities, it still has some disadvantages. We devised a new cannulatyped silicone voice prosthesis. Methods : 1) Devising a new prototype of cannula-typed silicone voice prosthesis. 2) Application of the prototype using canine animal model(laryngectormized dog) and fitting trial on human patient whose previously inserted Silicone voice prosthesis is not functioning due to presumed fungal infection. Discussion : Final form of prototype was made after several times of major and minor modifications. Insertion of the newly developed Cannula-typed Silicone voice prosthesis on canine animal model and human trial were done without any difficulty. There were no serious leakage of saliva or food during swallowing. Conclusion : The newly developed Cannula-typed Silicone voice prosthesis(So-Mang$\circledR$) and the modified replacement method will further improve the results of post-laryngectomized prosthetic voice rehabilitation. Long-term animal study and human trial are planned in the near future.

Steam turbines, gas turbines, multistage centrifugal compressors are operated over the range of the first critical speed. In these rotors flexible rotor balancing technique is necessary. In such balancing, influence coefficients are measured by rotating a rotor with trial weight. But for the large rotor, the measurement of influence coefficient takes much time and it reduces the cost efficiency. In this paper the new influence coefficient with rotation of rotor is proposed. First the theoretical background of the method is presented and it is applied to the simple flexible rotor model. Then the experiments are performed and the results of presented method are compared with those of analytical method. By using the obtained influence coefficient, balancing of the flexible rotor is performed.

A new Sikbangpoong(Peucedanum japonicum Thunberg) variety, 'Sikbangpoog 1', was developed through a pure line selection at the Kyougpuk Provincial RDA during the period of 1990 to 1995. The variety was characterized to have higher stem height, leaf number and seed production, and larger root diameter compared with the check variety of Bonghwa Sikbangpoong but plant height of 'Siknagpoong 1' was similar to that of the check variety and it was also more tolerant to water and heat stress. Root color of 'Sikbangpoong 1' was yellowish brown and root shape of the variety was straight and conical. The root yields of Sikbangpoong 1 in yield trial, regional adaptation trial and farmer's field trial were always 10-28% higher than those of the check variety.

Currently major countries, including the USA, have developed and contrived to activate ADR(Alternative Dispute Resolution) in order to both choose effective means for dispute resolution and establish the reformation of the judicial system; thus meeting people's revamped expectations due to the rapid increase of, and diversification in, civil disputes. This is why there has been some haste in many countries to organize systems for this, so called, 'the Fundamental ADR Act' which regulates the essential structure to accelerate the use of ADR and strengthen the links with trial procedures. For example, in 1999 Germany revised it Civil Procedure Act, to allow for a pre-conciliation process in cases involving only small sums of money. Whilst, with regard to the Civil Procedure Act in France, new regulations have been introduced with regard to actions before either a suit or return to conciliation. In the United Kingdom, as far back as 1988, additions to the legal structure allowed for expansion of regulations applying to ADR. By 1999 the new ADR regulations were part of the legal structure of the UK Civil Procedure Act. The USA passed the federal law for ADR in 1998. Since then the world has tried to enact this model in UNCITRAL on international conciliation. When we consider this recent trend by the world's major countries, it is desirable that the fundamental law on ADR should be enacted in Korea also. This paper traces the object, and the regulatory content required, for the fundamental ADR law to be enacted in Korea's future. Firstly, the purpose of the fundamental ADR law is limited only to the private sector, including administrative and excluding judicial sector and arbitration, because in Korea the Judicial Conciliation of the Civil Disputes Act, the Family Disputes Act and the Arbitration Act already exist. Secondly I will I examine the regulatory content of the basic ADR Act, dividing it into: 1)regulations on the basic ideology of ADR, 2)those on the transition to trial procedures of ADR, and 3)those on the transition to ADR from trial procedures. In addition I will research the regulatory limitations of ADR.

During the sea trial test for the aerovane in AOE-II, a malfunction occurred in the wind detector movement around 40 to 90° on the starboard side and around 270 to 320° on the port side. The purpose of this study was to analyze and improve the cause of the above phenomenon. The wind detector was covered with a mast structure and was not affected directly by the blowing wind, and a vortex air current was formed behind the mast structure, causing the motion malfunction. The above problem was solved by moving and installing the wind detector on the newly installed mast yard. After conducting vibration analysis and reviewing the effects of vibration, the wind detector was installed in the new mast yard and verified by a sea trial test. Since the improvement plan was slightly effective, the position of the wind detector moved away from the mast on the new mast yard and was re-verified through a sea trial test. The movement malfunction of the wind detector did not occur, confirming that it is an appropriate improvement plan.

This study discusses challenges of running expandable profile liners (EPLs) to isolate trouble zones in directional section of a deep well, and summary the expandable profile liner technology (EPLT) field trial experience. Technically, the trial result reveals that it is feasible to apply the EPLT solving lost-circulation control problem and wellbore instability in the deep directional section. Propose schemes for optimizing the EPLT operation procedure to break through the existing bottleneck of EPLT in the deep directional section. Better-performing transition joints are developed to improve EPL string reliability in high borehole curvature section. High-performing and reliable expanders reduce the number of trips, offer excellent mechanical shaping efficiency, simplify the EPLT operation procedure. Application of the expansion and repair integrated tool could minimize the risk of insufficient expansion and increase the operational length of the EPL string. The new welding process and integrated automatic welding equipment improve the welding quality and EPL string structural integrity. These optimization schemes and recent new advancements in EPLT can bring significant economic benefits and promote the application of EPLT to meet future challenges.

Social interactions often involve encountering inconsistent information about social others. We conducted a functional magnetic resonance imaging (fMRI) study to comprehensively investigate voxel-wise temporal dynamics showing how impressions are anchored and/or adjusted in response to inconsistent social information. The participants performed a social impression task inside an fMRI scanner in which they were shown a male face, together with a series of four adjectives that described the depicted person's personality traits, successively presented beneath the image of the face. Participants were asked to rate their impressions of the person at the end of each trial on a scale of 1 to 8 (where 1 is most negative and 8 is most positive). We established two hypothetical models that represented two temporal patterns of voxel activity: Model 1 featured decreasing patterns of activity towards the end of each trial, anchoring impressions to initially presented information, and Model 2 showed increasing patterns of activity toward the end of each trial, where impressions were being adjusted using new and inconsistent information. Our data-driven model fitting analyses showed that the temporal activity patterns of voxels within the ventral anterior cingulate cortex, medial orbitofrontal cortex, posterior cingulate cortex, amygdala, and fusiform gyrus fit Model 1 (i.e., they were more involved in anchoring first impressions) better than they did Model 2 (i.e., showing impression adjustment). Conversely, voxel-wise neural activity within dorsal ACC and lateral OFC fit Model 2 better than it did Model 1, as it was more likely to be involved in processing new, inconsistent information and adjusting impressions in response. Our novel approach to model fitting analysis replicated previous impression-related neuroscientific findings, furthering the understanding of neural and temporal dynamics of impression processing, particularly with reference to functionally segmenting each region of interest based on relative involvement in impression anchoring as opposed to adjustment.
