Avian vocalization has been main topics in studying animal communication. The structure and usage as well as development and function of vocalization vary enormously among species and even among populations, and thus we reviewed the general patterns of song learning and the consequences of song communication in birds at the behavioural level: first, we compared the different learning phenomena between non-songbird and songbird, and we investigated the learning process of songbird both in the field and in the lab, which are needed to fully understand vocal communication. Second, we discussed a recent trend of sexual selection hypothesis explaining the structural and functional diversity of song in songbirds with repertoire and presented how the repertoire is actually used between neighbours based on individual recognition.

Congenitally corrected transposition of the great arteries is a rare congenital heart anomaly, in isolation, has no hemodynamic consequences. It is usually associated with one or more of a variety of intracardiac lesions, ventricular septal defect, valvular or subvalvular pulmonary stenosis, and deformity of the systemic atrioventricular valve with insufficiency. This report describes a successful two stage operation for congenitally corrected transposition, [SLL] type, with ventricular septal defect, pulmonary atresia, persistent ductus arteriosus, and atrial septal defect. A 9 years old patient underwent modified Blalock-Taussig operation because of severe pulmonary hypoplasia. 2 years later a corrective operation, direct closure of ASD and PDA, VSD closure with Dacron patch, Enlargement of left pulmonary artery with pericardial patch and Relief of ROTO with Rastelli procedure could be successfully performed without complication.

A. Bejancu [2] was the first who instigated the new concept in differential geometry, i.e., CR-submanifolds. On the other hand, CR-submanifolds were generalized by B. Y. Chen [7] as slant submanifolds. Further, he gave the notion of a Kaehlerian slant submanifold as a proper slant submanifold. This article has two objectives. For the first objective, we derive Simons' type formula for a minimal Kaehlerian slant submanifold in a complex space form. Then, by applying this formula, we give a complete classification of a minimal Kaehlerian slant submanifold in a complex space form and also obtain its some immediate consequences. The second objective is to prove some results about semi-parallel submanifolds.

This study describes the effects of demographic transition on the environmental changes in Korea. The basic framework of this study is a path model. This study analyzes the effects of population growth, urbanization and industrialization on the environmental deterioration. In doing this, this study illustrates the changing patterns of population growth, urbanization and industrialization. This study also shows the changing patterns of environmental conditions, focusing on air pollution, water pollution and wastes. Finally, this study deals with the consequences of the environmental deterioration, especially focusing on the changing quality of life in Korea.

Cable-stayed bridges are often used in modern bridge engineering for connecting two geographical points of long distance. A special load case to cable-stayed bridges is earthquake, which can produce horizontal as well as vertical movements on the pylons of the bridge. These movements may be transient in nature, i.e., only resulting in the transient vibration of the bridge, but causing no damage consequences. In some extreme cases, they may cause permanent subsidence on one or more pylons of the bridge. In this paper, the effect of pylons' subsidence on the dynamic deformations of the bridge and on the cables' strength is thoroughly studied. Conclusions useful to the design of cable-stayed bridges will be drawn from the numerical study.

The goal of any Model Order Reduction (MOR) technique is to build a model of order lower than the one of the real model, so that the computational effort is reduced, and the ability to estimate the input-output mapping of the original system is preserved in an important region of the input space. Actually, since only a subset of the input space is of interest, the matching is required only in this subset of the input space. In this contribution, the consequences on the achieved accuracy of adopting different reduction technique patterns is discussed mainly with reference to a linear case study.

Purpose: This study was done to clarify the concept analysis of positive psychological capital. Methods: Walker and Avant's concept analysis process was used in this study. CINAHL, ProQuest, Web of science, NDSL, RISS databases from 2004 to 2016 were searched using the keywords 'Positive psychological capital' and 'PsyCap'. Sixty-one relevant articles and three book were finally selected. Results: Analysis of identified literature indicated that positive psychological capital attributes were developable potential, positive cognition, expression of emotion, multiple psychological capability, and resources with positive effect. The antecedents were goal achievement, training, leader's motivation, and supportive organizational environment. The consequences were overall wellbeing which is composed of individual's physical, psychological and social wellbeing and enhancement of work outcome. Conclusion: The findings in this study provide a definition of the concept of positive psychological capital and theoretical evidence for the future research for nurses including program development.

Purpose: This study was to develop a substantive theory on the conquering experience of group-bullies among teenagers, and thereafter suggest a model for solving the problems. Method: Data collection and analysis was proceeded by a method of Grounded Theory. Data was collected by interviewing the participants. Five teenagers participated in this study who had already overcome the situation. Result: In the analysis 31 concepts, 6 categories, and 14 subcategories are extracted from the raw data, and all are constituted on the paradigm model. The causal condition is a painstaking of participants. The context is affirmative reconsidering and the phenomenon is conquering difficulties. The intervening condition is a positive intervention of a supporting system and the strategy for action/interaction is building a relationship. The consequences of this analysis is harmonizing. Conclusion: The results of this study suggest adequate ways of conquering group-bullies. These are positive attitudes towards solving problems and the full use of support systems surrounding them.

The objective of this study is to report the improvement of the patient with Acute Disseminated Encephalomyelitis (ADEM) with Korean Medical intervention. The patient, diagnosed as ADEM, was treated by acupuncture, moxibustion and herb medicine and wild ginseng distilled herbal acupuncture. We evaluated the consequences by checking Manual Muscle Test (MMT), Korean Version of Barthel Index (K-MBI). As a result, the patient improved significantly MMT and K-MBI inclined. In ADEM, the initial diagnosis is important, and through a Korean medicine, we were able to achieve meaningful treatment result. There is a limit on this study due to sufficient number of case, thus, further studies will be needed.

A ring R is called generalized regular if for every nonzero x in R there exists y in R such that xy is a nonzero idempotent. In this paper, we observe some equivalent conditions for the generalized regular rings that are abelian in terms of idempotents, and we also investigate the primitivity of an idempotent for such a ring. By using the investigation, we characterize such a kind of rings that are noetherian by showing that an abelian generalized regular ring R is noetherian if and only if R is isomorphic to a direct product of finitely many division rings. We also observe some interesting consequences of our results.
