The MobileNetV3 is specially designed for mobile devices with limited memory and computing power. To reduce the network parameters and improve the network inference speed, a new lightweight network is proposed based on MobileNetV3. Firstly, to reduce the computation of residual blocks, a partial residual structure is designed by dividing the input feature maps into two parts. The designed partial residual structure is used to replace the residual block in MobileNetV3. Secondly, a dual-path feature extraction structure is designed to further reduce the computation of MobileNetV3. Different convolution kernel sizes are used in the two paths to extract feature maps with different sizes. Besides, a transition layer is also designed for fusing features to reduce the influence of the new structure on accuracy. The CIFAR-100 dataset and Image Net dataset are used to test the performance of the proposed partial residual structure. The ResNet based on the proposed partial residual structure has smaller parameters and FLOPs than the original ResNet. The performance of improved MobileNetV3 is tested on CIFAR-10, CIFAR-100 and ImageNet image classification task dataset. Comparing MobileNetV3, GhostNet and MobileNetV2, the improved MobileNetV3 has smaller parameters and FLOPs. Besides, the improved MobileNetV3 is also tested on CPU and Raspberry Pi. It is faster than other networks

The Harry Potter series is considered to represent the multicultural aspect of contemporary British society and to show critical perspectives of racism. This series, however, also includes many elements of British imperialism. This paper examines the ideas about education and Harry's role in relation to British imperialism. One of the main ideas prevalent in 19th century British boys' public schools was that people's blood origin is the most important element in determining their characteristics, ability and moral qualities. The students' inherited capacity and their family background are more highly regarded than their secondary learning and training. This reflects a 19th century concept that ultimately, inborn quality makes 'a hero', a truth presented in the educational policies of Hogwarts. Hogwarts' educational policies and systems can also be related to 'developmentalism', which defines children as imperfect, in-progress and incomplete, thus needing proper training and discipline. As this concept functioned to justify the control of children while educating them, Hogwarts adopts diverse controlling devices and oppressive policies, which are mainly justified in the name of education. On the one hand, child characters are controlled and oppressed by the school authorities, on the other hand, some of the students such as Harry have remarkable magic powers enough to resist the adult authority and even to save the magic society from the evil power. Harry plays dual roles, which the British boys of the Empire were assigned from their society; they are important heirs to conquer the 'evil' or 'barbarous' world but need to be obedient to a 'good' authority to achieve the mission. Harry's magic power and self-discipline ultimately contribute to fulfilling Dumbledore's mission, which mirrors 19th century British boys' roles as the heirs of the British Empire.

This study examined the time allocation pattern of farm wives. In particular it addressed i)the differences in extent of time spent in farming housework child care and leisure between on-farm and off-farm seasons ii)differences in the extent of time spent in such activities among farm wives and urban wives and iii) the determinants of time spent in such activities. To achieve these goals a system of time allocation equations based on household production theory was employed. On hundred and eight farm wives wiere selected in 1993 by the methods of judgement sampling and cluster sampling. Two major questions in the survey elicited sociodemographic information and time-use of farm wives using the time-diary method, The results indicate that farm wives different decisions about how to allocate their time to farming housework child care leisure during on-farm and off-farm seasons. In addition it was that farm wives are more likely to have dual responsibilities than are urban wives. Finally in the off-farm season education number of younger children and region were significant variables in explaining the time allocation decisions of farm wives. However only age was a significant factor in their time allocation decisions during the on-farm season. This leads one to conclude that time allocation is not a choice for farm wives in the on-farm season.

This study uses qualitative data to examine the dynamics and barriers of the delayed family formation phenomenon among the never-married professionals in Korea. The data was drawn from focus groups of 14 never-married professionals aged 28 through 40. The investigation depicts several dimensions of the circumstances of never-married professionals that have not garnered much attention in the literature. This research provides initial evidence of critical influences within the socio-cultural contexts of the participants' dating behaviors as well as the willingness to many. Two different realities, based on gender, were discovered: both male and female voluntarily delayed marriage to pursue their career, education and success. As both reached their career goals, however, male participants experienced a rise in their value as a marriage prospect whereas females experienced decreased value as a marriage prospect. Hence, neo-traditional familism was the dominant value among the participants, but it also functioned as a major barrier to family formation because in the present value system, female professionals, must still struggle with the dual burdens of work and family management.

The skin of the eel goby, Odontamblyopus lacepedii, consists of epidermis, dermis and subcutis. The epidermis has three layers: the outermost layer, middle layer and stratum germinativum. The outermost layer is composed of polygonal cells or rather flattened cells, and mucous gland cells of acid mucopolysaccharides. The middle layer consists mainly of swollen small or voluminous epidermal cells and shows a web-shaped structure. The thickness of the epidermis depends on the various sizes and the number of layers of the swollen cells. Well-developed lymphatic spaces containing lymphocytes exist in the stratum germinativum and small scales are embedded in the dermis. A large number of blood capillaries are present just below the basement membrane, and a definite area giving AB and PAS positive was present between the basement membrane and scales, Taste buds ave distributed on surface of the epidermis at intervals. Considering the structural features of the skin, it may be considered that O. lacepedii is more likely to be related to cutaneous respiration as a dual respiratory system.

Occupational health services in Korea have been operated as dual types: one is operated by occupational health care manager and the other is health care agency without their own personnel. The performance of occupational health service should be different due to the variety of characteristics of health care manager and workplace, qualification of health care manager. This study is to analyze performance of occupational health care services with a particular consideration of job, based on comparing those two types of health care management to show on the basic data for the settlement of more qualitative. health care management system at workplace. For this study, total 391 places in Seoul and Inchon city area: 154 places (39.4%) managed by designated. health care manager and 237 places (60.6%) by the agency with their commission are selected as research samples. Tools for data collection are questionnares have been investigated during the period of 20 September 1993-20 December 1993. Those data are compared with percentiles, mean, standard deviation due to the characterstics of each variable and analyzed for impacting factors with relation to the using multiple regression analysis using SPSS PC program, especially using t -test method in order to compare each type of health care management. Conclusions observed from the tests and each comparison could be summerized as follows : 1. Occupational health care have been accomplished at workplaces with designated people than with agencies people, and coverage rate of the occupational health care services has differences, due to management types. The reason of these results is due to visit only one or two times monthly by the agencies, while their own health care manager obsess, at the workplaces all the times. 2. The common sickness management is the most accomplished item in health care area of occupational health care services, while the preventive care and control for the workers who have serious health problems are insufficient in workers health care area. 3. An insufficient accomplishment of overall health education has been shown because it is difficult to perform health education due to almost no chance of the direct introduction at workplaces. Therefore a strong support system for making and supplying the media is necessary in order to activate indirect health education by means of media. 4. Because health care managers and the agencies managers where take the workplaces for this study are almost nurses who have been comparatively high work site rounding rate about an environmental management at the workplaces, that non-profession can also do it, the activities about the professional area not enough. Therefore, an appropriate referral system should be established in order to complement professional area. 5. Two factors which have an effect on the coverage rate of occupational health care services are : one is those from the workplaces such as type of services, the number of workers, the number of harzadous factors and safety & health committee, the other from health care organization about whether there is its own manager or not.
