In this paper,I present an extended two-level model using LR parsing techniques.The LR-based two-level model not only guarantees effcient morphological processing but also achieves a higher degree of descriptive adequacy than Koskenniemi's original model.The two-level model is augmented with an independent morphosyntactic module based on feature-based CF word grammar.By adopting a CF word grammar,our model is capable of dealing with complex words with discontinuous dependencies without having duplicate lexicons.It is shown how LR predictions manifested in the parsing table can help the morphological processor to minimize the dictionary lookup process.

The wind-speeds among geographically close wind-farms have high correlations seasonally. This paper presents a novel wind-speed sampling method which sincerely reflects the correlation among wind-speeds of different wind-farms. In the proposed method, the wind-speed samples are generated through the statistical data analysis of the measured past wind-speed data and are adequate to be applied to generation adequacy assessment based on random sampling. In the proposed method, the specific probability distribution need not to be assumed and sufficiently accurate wind-speed samples can be generated based only on the measured past data. The proposed method is applied to the two wind-farm problem to show its applicability.

In competitive electricity markets, the System Operator (SO) coordinates the overall maintenance schedules whenever the collective maintenance schedule reported to SO by Gencos & Transco in the pool does not satisfy the specified operating criteria, such as system reliability or supply adequacy. We propose a two-layer mathematical algorithm amenable to maintenance scheduling problem into master problem and sub-problem. The master problem coordinates the scheduling, and sub-problem, DC optimal power flew, checks the adequacy. The proposed algorithm was demonstrated with a case study.

Photographic lenses and an aspheric optical pickup-lens are designed by using damped least-squares(DLS) method. We start optimization with arbitrary initial damping factor. To improve the rate of convergence and the stability in optimization, we apply the special procedure that estimates numerical adequacy of derivative increments of variables to the DLS method. When the initial damping factor is almost equal to the median of series of eigenvalues, the convergence and the stability of the method significantly are improved. Optimized lenses have the performance of each target.

The purpose of this study is to develop a valid and reliable infant observation scale based on the national curriculum for childcare centers. The study was carried out using the final draft of the Infant Observation Scale for 1 year old infants. The scale consists of 42 items in 6 areas. Whereas the final draft of the Infant Observation Scale for 2 year old infants consists of 52 items in 6 areas. The subjects of this observation scale were 120 infants from the city of Busan. The results of the Infant Observation Scale for the 1 year old infant analysis for the purpose of test adequacy indecates that the internal consistency reliability is from .88 to .97. The results of the Infant Observation Scale for 2 year old infant analysis for test adequacy shows that the internal consistency reliability is from .76 to .97.

Chronic obstructive pulmonary disease (COPD) is an ambulatory care-sensitive condition, and effective treatment of outpatients can prevent worsening of the illness and hospitalization. Current COPD guidelines provide appropriate guidance for the diagnosis and treatment of patients with COPD. In fact, it has been shown that when appropriate guidance and treatment are performed, the morbidity and mortality rates of COPD patients are reduced. However, there is a gap between the clinical guidelines and the actual clinical treatment. Therefore, the Health Insurance Review and Assessment Service (HIRA) conducted an evaluation of the adequacy of COPD diagnosis and treatment using the Claims Database of HIRA. This review provides a summary of the COPD adequacy assessment results reported by the HIRA and some brief comments on the results.

The changes of social climate in respecting differences and needs of each diverse groups and human equality have caused the disabled to persue quality of life, through enabling their lives more independent. The purpose of this research was to find out adequacy of the residence and living behavior of the hearing impaired. Though this reach it was expected to find out environment features which have become obstacle in maintain their life independent in normal way and the way of improving their environment. Small group workshop with three hearing impaired persons was implemented. Living behavior and physical environmental characteristic of dormitory and interaction between them were identified. The need of non auditorial communication for the hearing impaired found far beyond required guidelines of the disabled Act. Design professionals need more profound knowledge with and ethical and humanistic attitude to find and satisfy the need of disabled.

Graphical paradigms for assessing the adequacy of models in logistic regression are discussed. The residual plot has been widely used as a graphical tool for evaluating the adequacy of the model. However, this approach works well only for linear models with constant variance, and the alternative approach, the marginal model plot, has its defects as well. We suggest a Chi-residual plot that overcomes the potential shortcomings of the marginal model plot.

An iterative numerical computational algorithm is presented to design a plate or shell element subjected to membrance and flexural forces. Based on equilibrium consideration, equation for capacity of top and bottom reinforcements in two orthogonal directions have been derived. The amount of reinforcement is determined locally, I. e., for each integration point, from the equilibrium between applied and internal forces. Three cases of design are performed for slab element (used by Marti(1987)) and shell element (used by Kirscher and Collins(1986), by Polak and Vecchio(1993)) to verify the adequacy of the present design method for reinforced concrete shells. Based on nonlinear analyses performed, the analytically calculated ultimate load exceeded the design ultimate load. This shows the adequacy of the design method present in this study at least for slab and shell element case studied. To generalize the conclusion more design-analyses should be performed with different shell configurations.

The purpose of this study was to empirically verify the influence of variables on leisure participation and leisure satisfaction of single working people and the relative contribution of individual leisure participation and family leisure participation. The subject of this study were 176 single working people in Pusan and interviewed with a questionnaire. The data were analyzed by SPSS/PC＋ program for the frequency, mean, standard deviation, Cronbach'$\alpha$, factor analysis and regression. The major results of this study were as follows : 1. The score of family leisure participation were higher than individual leisure participation. The Level of leisure satisfaction was relatively high. 2. Variables that affect the leisure participation were job, degree of information using and perception level of the adequacy of household income. 3. Variables that affect leisure satisfaction were perception level of the adequacy of household income and individual leisure participation.
