The purpose of this study is to compare the verbal control modes used by fathers or mothers toward their children. The subjects of this study are 148 fathers and 159 mothers whose children attend kindergartens. For data analysis, t-test, one-way ANOVA and Scheffe's test, Pearson's correlation, and two-way ANOVA were used. The major findings are as follows: First, the status-oriented verbal control mode was most frequently used by both fathers and mothers, while the order-oriented verbal control mode was used less frequently by parents. Second, both fathers and mothers used three verbal control modes more often toward boys than toward girls. Third, the comparison of verbal control modes between fathers and mothers revealed that mothers, rather than fathers, used three verbal control modes more frequently toward their children. Fourth, mothers with higher education, rather than fathers with higher education, used the status-oriented verbal control mode and personality-oriented verbal control mode more frequently toward their children.

This study aimed first to correctly understand informationalization of distribution, that is POS System, EDI, EOS, and distributing VAN, second to observe the present condition and preceeding examples of construction of informationalization of distribution in our country and to execute analysis of corroborative evidence regarding informationalization of distribution centered on distributing companies in Pusan and Taegu districts, third to grasp the impeding primary factors when informationalization is built up, and fourth to present effective building up lans of informationalization of distribution in Pusan and Taegu districts which will be the foundation of informationalization of distribution in the distributing business circles. The writer studied, for the method of study, by dividing into theoretical study, research portion of the present condition and preceeding examples of building up informationalization of distribution, and analysis of corroborative evidence. For the theoretical study portion and analysis examples, the study method by documentary records was applied, and domestic and foreign books, theses and periodicals related to the informationalization of distribution were consulted. For the analysis of corroborative evidence, the writer studied by questionaires regarding opening of distributing markets, distriubuting environment and distributing information system of the distributing market by the retail dealers as its objects, and selected research by questionaires to collect information by personally visiting each company. About 15 universities and junior colleges related to the distributing industry in our country produce about 1,280 of fundamental manpower related to distrribution every year, and a portion of large-sized distributing companies established and are managing even inter-company colleges, but it is the real situation that these are not sufficient in quality and quantity. In order to cultivate manpower specialized in distribution, the industry, universities and government, forming a trinity, should cope with the matter jointly, and especially, the government level should newly establish subjects of study related to the distribution drastically and political and financial support should be necessarily followed. Also, if POS system is induced, as the source of tax revenue is completely exposed, compared with those companies which do not induce POS System, they will suffer disadvantage, so preferential treating method is necessary in case of application of valued added tax or income standard. The customary practice of dealing without data harmful to normal commercial transaction order and against equity is pointed out as the most fundamental problem point being held by the distributing business circle in our country. For the sake of effective building up the distributing information system, the source making rate shall be raised, the ratio of domestic made instruments of POS System shall be increased, by developing EOS System which can be connected with manufacturing companies, POS System shall be utilized effectively by connecting with the management information system of the whole enterprises, EIS (Executive Information System) and various data base, and shall be connected with EOS with other components of distributing channel and EOS and EFT (Electronic Fund Transfer) system shall be connected through EDI or VAN. Such distributing information system can accomplish composite distribution information systematization, so it can promote greatly the management power not only of distributing business but manufacturing business.

<P>Inorganic‐based flexible light‐emitting diodes (LEDs) using single‐crystalline GaN/ZnO coaxial nanorod heterostructures grown directly on large graphene films are reported on page 4614 by Gyu‐Chul Yi and co‐workers. The LEDs demon‐strate reliable operation in a flexible form, with no significant degradation in their electroluminescent or electrical characteristics. This approach provides a general and rational route to develop many different inorganic optoelectronics in flexible or stretchable forms. </P>

Cryptococcosis, which is caused by the Cryptococcus species complex (including Cryptococcus neoformans and Cryptococcus gattii), is well known as one of the most important medical problems. However, the of the Cryptococcus species complex is still limited to pneumonia and meningitis. In particular, the differences in virulence among the five major serotypes of the Cryptococcus species complex are not fully understood. To elucidate the virulence of the Cryptococcus species complex when it is disseminated hematogenously, rats were infected by different strains of the Cryptococcus species serotype, and their histopathological characteristics were compared after infection. The cumulative mortality ratio of rats infected with serotype B strain was slightly higher than in the other experimental groups. In addition, the average recovery of the Cryptococcus species complex from rats infected with serotype B strain was significantly higher than in the other groups in almost all organ samples except spleen. The recovery of the Cryptococcus species complex was associated with the severity of histopathological lesions, including bleeding, inflammation, and tissue damage in all organs. In rats infected with serotype B strain, the virulence was the most severe, especially in the lungs and liver. These results indicate that the pathophysiology of the Cryptococcus species complex infection differs according to serotype.

The formation of brown colonies due to phenol oxidase activity on classic agar media containing natural material extracts of Helianthus annuus or on medium containing L-3,4-dihydroxyphenylalanine has been used to identify Cryptococcus species complex. In this study, various natural materials were used to develop a modified medium and to identify five major serotypes of Cryptococcus species complex. Serotypes A, D, and A/D were pigmented on medium using Perilla frutescens var. japonica Hara (PerJ agar) after a three-day incubation. Serotypes B and C were pigmented on PerJ agar after four- and five-day incubations, respectively. Growth time and pigmentation of the five serotypes occurred more rapidly on PerJ agar than on the other media. In addition, colony morphology, size, and pigmentation were specific by serotype. In conclusion, PerJ agar should be used in clinic settings to identify Cryptococcus species complex and its serotypes rapidly.
