The characteristics of agricultural water rights were examined for the national rivers in Korea. We suggest that the national rivers could according to the actual management organization of agricultural water right be categorized into national management rivers KOWACO(Korea Agrcultural & Rural Infrastructure COrporation) management river. The agricultural water right between the national and KOWACO management rivers have different characteristics for irrigation period permit procedure water charge and type of water right. The agricultural water rights are granted in the natural discharge less than reference droughty discharge for most of national management rivers and in the developed discharge for the KOWACO and KARICO management rivers. The current system of agricultural water rights is complicated inconsistent and incapable of coping with unusual drought and therefore it needs to be improved.

Since water leakage and cracks are not the source of serious problems such as long-term lowering of performance and durability of a stricture, including damages to operating facilities of a structure, damages to internal finishing materials, exhibition, and goods, and pollution of residential environment, they might have led to development of positive coping skills; however, an instant loss of lives or property due to earthquake, explosion, typhoon, or a fire was indeed neglected. In these days, repair materials for leakage cannot help but being taken in temporary way without any noticeable countermeasure. This kind of repair is socially criticized many times that is defective construction even if this costs a lot. It was not arrange the standard for construction methods of sealer of injection type for leakage maintenance, even it has been used various type of construction methods for leakage part. In conclusion, we suggest that the construction methods of sealer of injection type for leakage maintenance for leakage to establish the leakage repairing technology as increase of structure demand. Therefore, it would be possible to provide a stage-by-stage solution by developing systematic research activities among the industry, schools, and research institutes to spread maintenance management techniques globally through technical solution to water leakage and cracks, acquisition of structural safety with prolonged durability for life cycle, reduction of water leakage repair expense s, and so on.

This study was undertaken to find out the causal perception of rheumatoid arthritis patients, and to understand the typology. The Q-population consisted of 236 statements of causal perception were collected. Thirty eight Q-samples of causal perception were selected. The P-sample for this study were made up of 28 first visiting female rheumatoid arthritis patients from a rheumatoid arthritis specialty hospital. Each respondent responded Q-set of causal perception according to 9-point scale. The result of Q-sorting were coded and analyzed using QUANL PC program. 1) Typological Observation on Causal Perception (1) Physical Fatigue Type : Type 1 perceived that the illness occurred due to excessive work requiring physical labor or strain that had occurred from not resting after excessive physical labor, therefore, thinking the origin of the illness was from physical strain. (2) Physical origin Type : Type 2 perceived that the major cause for the illness is not only excessive physical labour but also fecundity and old age. (3) Causality to Environment Type : Type 3 perceived that rheumatoid arthritis occurred from injury to the joints or bad and humid weather. (4) Conscience of Guilty Type : Type 4 consisted of people with guilty conscience for lack of religious commitment. They perceived that the illness was a punishment from God for not praying or because of bad luck. (5) Rationally Perceiving Type : People who belong in type 5 perceived the cause of illness in light of scientific facts such as genetics, unbalanced diet or lack of exercise. (6) Psychological Stress Type : People who belong in type 6 believed that excessive stress was the cause of the illness. 2) Emotions of Rheumatoid arthritis patients Rheumatoid arthritis patients' positive emotions included determination, courage, coping, acceptance, hope, and adoption ; and their negative emotions were prostration, worry, stupor, conflicts, grievance, giving-up, resignation, depression, loss, solitariness, fear, anxiety, avoidance, anger and loneliness. Rheumatoid arthritis patients experience different level of emotions from their suffering experience from the severe pains. Rheumatoid arthritis patients also experience negative emotions when they could not perform self-care and lose their self-esteem from painful suffering ; however, they regain positive emotions when they recover from pain with the use of drugs, physical therapy or exercise. Their emotional states are closely connected to level of and presence of pain.

The purpose of this study was to clarity the concept of health insensitivity using Hybrid model, which consists of three phases： theoretical, empirical, and analytic. In the theoretical phase, the definitions of health insensitivity were searched in korean dictionary and examples used in the websites because the concept of health insensitivity has never been studied before. Two dimensions of health insensitivity emerged out from this investigation were cognitive and behavioral. And then a working definition of health insensitivity was established. The sub-concepts and related factors of health insensitivity were identified through the extensive reviews of the literature focusing on two dimensions of cognitive and behavioral. In the empirical phase, in order to obtain description of health insensitivity, face-to-face in-depth interviews were conducted with nine persons who are not related to professional health care. Grounded theory approach was applied to analyze these qualitative data. In the final analytic phase, theoretical results and empirical results were analyzed in the integrated way and a theoretical framework of health insensitivity was established. A refined definition of health insensitivity was that decreased health risk perception in cognitive dimension and conduction of the unhealthy behaviors in behavioral dimension. Sub-concepts of decreased health risk perception were optimistic bias and decreased general fear. Sub-concepts of unhealthy behavior were doing health threatening behavior and not doing desirable health behavior. The contact of health information was a causal condition of health insensitivity. Optimistic disposition, health locus of control, and avoidance coping style were intervening conditions of health insensitivity. Three types of health insensitivity were identified： unconcern or ignorance type, optimistic bias type, and cognitive dissonance type. Finally, The implications of these findings for further research and nursing practice are discussed.
