Chromatography has been a method of choice in the separation of complex biological mixtures for the analytical purpose in particular for the last half of century. In current years, chromatographic method extends its use to the preparative separation where the productivity per resin amount and solvent use become a matter of concern. Recently, simulated moving bed (SMB) method which claims high separation efficiency of the ideal counter-current moving bed chromatography has become a workhorse of preparative separation. SMB technology was developed in the early 1960s for large-scale hydrocarbon separation by UOP and approximately 120 Sorbex units have been licensed to date. Recently, SMB separation technology has been successfully extended from hydrocarbons and sugars to fine chemicals, particularly biochemicals, from laboratory to pilot to production plant. In this paper, the current status of SMB and its modifications were reviewed.

Chromatography has been method of choice for the separation complex biologi-cal mixtures fro analytical purpose, particularly for the last fifty years. Its use has recently been extended to preparative separation where the productivity relative to the amount of resin and sol-vent used is a matter of concern. To overcome the inherent thermodynamic inefficiency of batch chromatography, as exemplified by the partial temporal usage of the resin and dilution of the product with the solvent, chromatography has been continually modified by separation engineers. Column switching and recycling represnet some of the process modifications that have brought high productivity to chromatography. Recently, the simulated moving bed (SMB) method, which claims a high separation efficiency based on counter-current moving bed chromatography. has be-come the mainstay of preparative separation, especially in chiral separation. Accordingly, this pa-per reviews the current status of SMB along with several chromatographic modification, which may be helpful in routine laboratory and industrial chromatographic practices.

The gantry is a device that moves fine chips from the feeder to the PCB. While the gantry is moving the part, the camera checks the condition of the part. The purpose of this paper is to find the path with the shortest travel time of the gantry and calculate the travel time according to the path. stop_motion is a way to check the status of the parts currently in use. This paper presents the moving_motion method and the fly_motion method with maximum speed in front of the camera. In addition the signature method was used to inspect the condition of the parts. When comparing the moving time of the three types of gantry, the moving_motion method improved by 9.42% and the fly_motion method by 17.73% compared to stop_motion. When the fly_motion method proposed in this paper is used for the gantry movement path, it is expected that productivity will be improved.

Moving techniques is made up the physical moving status of the flow distinction modulus (FDM) and stream distinction modulus (SDM) on the shudder moving shape. Condition of the distinction modulus by the shudder moving shape is organized the dangle moving system. As to define the physical moving of special signal on the matter, we compared a shudder value of the flow distinction modulus on the flow state. The concept of stream distinction modulus is analyzed the reference of stream distinction signal and stream distinction signal by the stream state. For detecting a variation of the FDM-SDM of the maximum-minimum and average in terms of the moving shape, and shudder moving value that is a shudder value of the top variation of the $Top-{\varepsilon}$ MAX-MIN-AVG with $(-0.817){\pm}0.15$ units, that is a shudder value of the peripheral variation of the $Per-{\varepsilon}$ MAX-MIN-AVG with $(-2.53){\pm}(-0.11)$ units, that is a shudder value of the limbus variation of the $Lim-{\varepsilon}$ MAX-MIN-AVG with $(-0.29){\pm}0.03$ units, that is a shudder value of the center variation of the $Cen-{\varepsilon}$ MAX-MIN-AVG with $(-0.09){\pm}(-0.01)$ units. The dangle moving will be to assess at the capacity of the physical moving shape for the control degree of distinction modulus on the FDM-SDM that is showed the flow and stream shape by the distinction modulus system. Dangle distinction system is adjusted of a shape by the special moving and is included a shudder data of dangle moving modulus.

Pain measurement tool were used graphic rating scale and Abstract of Korean Pain Language Scale. To analize the subject's general characteristics, past and present health status, daily living activity level, characteristics about pain, pain management methods statistical SPSS for win frequency were employed. The findings were as follows ; 1. There were 33(41.8%) male and 46(58.2%) female Below 69 year old were 20(25.3%), 70-79 year old were 42(53.2%), over 80 year old were 17(21.5%), mean age was 74(from 65 to 89). 2. Buddhist were 24(30.4%), Christian were 29(36. 7%), the other religious status or non religians were 26 (32.9%). 3. Past good health status were 63(79.7%), not so good status were 6(7.6%). Present good health status were 19(24.1%), moderated health status were 6(7.6%), not so good status were 14(17.7%). 4. Daily living activity limitation were 39(49.4%), nonlimitation of activity were 5(6.3%). 5. Walking limitation were 3(3.8%), nonlimitation walking were 52(65,8%). 6. Insomnia was 23(29.1%), no difficult were 38(48.1%). 7. Chronic pain complaints were 64(81%), diseases causes of pain were 25(31.6%), bad health behavior causes of pain were 27(34.2%). 8. Most pain area were back 30(29.4%), leg 17(16.7%), knee 16(15.7%), arm 13(12.7%), teeth, chest and head were each 5(4.9%), loin, trunk were each 4(3.9%), the other areas were 3(3%). 9. Pain intensity was 3.49(mean) by Korean Language Scale, 6.59(mean) by graphic rating scale. Sensitive pain was 3.5(47.9%), affective pain was 3(20.8%) It was high pain level and sensitive pain. 10. Most pain worse causes moving was 35(44.3%), pain relieving causes rest was 29(36.7%), 11. Pain management method were medication 40(42.1%), physiotherapy 23(24.2%), hospital 12(12.6%), the others 7(7.4%), none 13(13.7%). The conclusion ; Present health status of eldery was not so good. Almost half of them have some diseases. Most common diseases of eldery were arthristis, respitatory and heart problems. Foully nine percent of elderly had limitation of daily living activities. Eighty one percent of eldely had chronic pain. Most of them was back pain (30%). Pain intensity was high(score over 3.5). The worsening pain causes was moving and releiving causes was rest. Pain management method were pain medication, physiotherapy. Therefore, Nursing care plan for the elderly have to focus on pain because majority of elderly have chronic high level of pain related to the arthritis.

In recent years, conoeptualizations of the residential crowding phenomena have developed form deterministic approaches to functionalistic ones which emphasize the interaction of environmental , social, and personal variables. The influences of each variables which are believed to mediate the crowding perception have been tested. This study examines the association of the influence of socio-demographic variables, residential setting and previous residential experience with the residential crowding. Futhermore, the residential adoptation behavior in response to the crowding phenomena is analyzed. The results of a survey are as follows; 1)The most important variables which influence residential crowding are the residential setting variables such as the floor space and the measure of persons per room. Also the household income and the family structure influence the residential crowding. No previous residential experience effects were found. 2)The residential adoptation behavior is influenced by sex, age and socio-economic status of the family. Female and the age group of 20s and 30s tend to prefer such alternatives as moving or residential alterations and additions. On the other hand, male and the age group of 40s and 50s tend to prefer staying without nay alternatives or structural family adoptation. The group of higher socio- economic status tend to show higher preference to moving and alterations, and the lower ones tend to stay or take the alternative of the structural family adoptation. Years of education and the family structure do not influence the residential adopation behavior.

High aged society is rapidly progressing in Japan. The rate of aged person more than 65 years old in the population are estimated 25 % in 2017 and rate of younger population will be decreased at same time. As a result, it is estimated that the human resources that is looking after or supporting for the aged person will be drained in Japan. In the other hand, the society has to provide high quality of life in order to be improved living environment for aged person. To decrease the share of nursing and caring for the aged person, it is required that new supporting systems for aged person have to build up as soon as possible. But it is required that various kind of measurement for posture and movement in activities with a simple and single detector for the aged person. The measurement instrument has to be lightweight and simple structure. The results give us a simple measurement method are classified that the posture of sitting down, lying down in stationary statuses and walking, running and going to up and down on the stairs in moving statuses. The detected data will plane to transmit to wireless mobile system to the host computer.

Due to the high increment in usage and built-in advanced technology of smartphones, human activity recognition relying on smartphone sensor data has become a focused research area. In order to reduce noise of collected data, most of previous studies assume that smartphones are fixed at certain positions. This strategy is impractical for real life applications. To overcome this issue, we here investigate a framework that allows detecting the status of a traveller as idle or moving regardless the position and the direction of smartphones. The application of our work is to estimate the total energy consumption of a traveller during a trip. A number of experiments have been carried out to show the effectiveness of our framework when travellers are not only walking but also using primitive vehicles like motorbikes.

The automatic determination of vehicle operation status as well as continuous tracking of vehicle location with intelligent management is one of major elements to achieve the goals. Especially, vehicle operation status can only be analyzed in terms of expert experiences with real-time location data with scheduling information. However the scheduling information of individual vehicle is very difficult to be interpreted immediately because there are hundreds of thousand vehicles are run at the same time in the national wide range workplace. In this paper, we propose the location-based knowledge management system(LKMs) using the active trajectory analysis method with routing and scheduling information to cope with the problems. This system uses an inference technology with dispatching and geographic information to generate the logistics knowledge that can be furnished to the manager in the central vehicle monitoring and controlling center.
