Objective : The purpose of this study was to investigate establishment status of the mandatory courses designated by Ministry of Health & Welfare for qualification of sensory developmental rehabilitation specialist(SDRS), within curriculum of baccalaureate occupational therapy(BOT) programs in Korea Methods : This is a narrative study to investigate and analyze certain courses established in curriculums of all 4-years occupational therapy(OT) programs, which is 32 schools. Results : 1) The shared mandatory subject, 'Understanding Children with Disabilities(UDC)', has been established at 9 schools. For the branch mandatory subjects, 'Neuroscience(NS) or Neuroanatomy' has been established at all 32 schools, 'Sensory Processing Dysfunctions and Intervention(SPDI)' or 'Sensory Integration' has been established at 31 schools, and each of 'Assessment & Evaluation for Children(AEC)' and 'Practicum of Sensory Rehabilitation(PSR)' has been established 7 schools for same. 2) For the mandatory courses, all 32 schools were offering designated- and alternative courses of NS, SPDI, AEC, but there was no change in the number of schools offering the practicum course since there was no case of alterative for it. 3) In terms of general provision score, there were 4 schools for score 7, 4 schools for score 6, 2 schools for score 5, 1 schools for score 4, 2 schools for score 3, and 19 schools for score 2. Conclusion : Establishment of the mandatory courses required to the qualification of SDRS among the BOT programs in nation were investigated. Including alternative courses, all the branch mandatory courses except practicum course are established in all the 32 schools. However, the shared mandatory subject, UDC and the practicum subject were established in only few schools. In the provision level evaluation of BOT programs for the SDRS qualification, it is shown that many schools has been started the provision already but still many schools' curriculum did not reflect the willingness and accuracy well. For the schools planning successful accreditation in near future, it is recommended that they prioritize the establishment of the shared mandatory course and the practicum course since these two subjects are recognized as critical factors for that. In addition, it is also needed of comparative inspections for course title and syllabi based on the guideline provided by Ministry of Health & Welfare.

In the royal publishing process of the Joseon Dynasty, the main species of wood used for woodblock printing was recorded as Jajak-mok. Although the name Jajak-mok may suggest Jajak-namu(white birch), it is presumed to refer to a different type of wood than Jajak-namu based on its recorded habitat and usage in historical documents. The aim of this paper is to clarify that during the Joseon Dynasty, the term Jajak-mok referred to Geojesu-namu (Korean birch), while Jajak-namu was called Hwa-mok(樺木). Additionally, this paper explores how the term Jajakmok eventually became the name of white birch, Jajak-namu, used today. In the mid-18th century, Japan used the character 樺(hwa) to refer to Beot-namu(Sargent cherry). As Japanese encyclopedias entered Joseon, the term Hwa-mok began to refer to both Beot-namu and Jajak-namu, which is also called Bot-namu. Since the pronunciation of Boet-namu and Bot-namu are similar, the two trees were eventually unified under the name Boet-namu. In the 20th century, the official names of three trees were established. According to notifications issued by the Ministry of Agriculture and Commerce of the Korean Empire in 1910 and the Governor-General of Chosen in 1912, Hwa-mok(white birch) was renamed asJajak-namu. In 1968, Beot-namu(Sargent cherry) retained its original name, and Jajak-mok(Korean birch) was remained . In modern Chinese character dictionaries, the meaning of 樺(hwa) is listed as "1. Beot-namu(Sargent cherry), 2. Jajak-namu(white birch)." From this, we can infer the historical background in which the names of these three trees were mixed up.

In 1983 Harmand and Lima [5] proved that if X is a Banach space for which K(X), the space of compact linear operators on X, is an M-ideal in L(X), the space of bounded linear operators on X, then it has the metric compact approximation property. A strong converse of the above result holds if X is a closed subspace of either $\elll_p(1 < p < \infty) or c_0 [2,15]$. In 1979 J. Johnson [7] actually proved that if X is a Banach space with the metric compact approximation property, then the annihilator K(X)^\bot$ of K(X) in $L(X)^*$ is the kernel of a norm-one projection in $L(X)^*$, which is the case if K(X) is an M-ideal in L(X).

LA, Yong Joon (Coll. of Agr., Seoul National Univ.) Condial production of Cercospora beticola Sacc. on tomato juice agar. Kor. Jour. Bot. VI (1):8-10, 1963. Agar media containing various amount of tomato juice were tested to determine the degree of conidial production of Cercospora beticola. Non-sporulating culture on potato dextrose agar readily sporulated on agar media containing various amout of tomato juice 48 hours after transfer. Considerably small amount of sporulation occurred on agar media containing 10% of tomato juice. Sporulation increased considerably on media containing more than 20% of tomato juice; the higher the proportion of tomato juice in a medium, the greater the number of spores produced.

We propose time-optimal cornering motion trajectory planning and control algorithms for differential wheeled mobile robot with motor actuating voltage constraint, under piecewise constant control input condition. For time-optimal cornering trajectory generation, 1) we considered mobile robot's dynamics including actuator motors, 2) divided the cornering trajectory into one liner section, followed by two cornering section with angular acceleration and deceleration, and finally one liner section, and 3) formulated an efficient trajectory generation algorithm satisfying the bang-bang control principle. Also we proposed an efficient trajectory control algorithm and implemented with an X-bot to prove the performance.

The shoe last which is the framework for the shoemaking is intensively combined with the 3D data and technologies. International shoe companies have already commercialized 3D printing technology in producing the shoe, but domestic shoe companies are still in their early stages. This study used the 3D scanning, 3D modeling and 3D printing of the high-technology to make the shoe last. This 3D producing processes should be helpful in building competitiveness in domestic shoe industry. The 3D foot scanning data of men in 30s(n=200) were collected in SizeKorea(2010). The basic statistics, factor and cluster analysis were performed. They were categorized in 3 groups by 3D foot measurement data, and the standard models were selected in each group. The cross sections in XY, YZ and XZ planes sliced from 3D scan data of the standard model were used in the sketches of the 3D shoe last modeling. The 3D shoe last was modeled by Solidworks CAD and printed by MakerBot Replicator2; a desktop 3D printer. This research showed the potential for utilization of 3D printing technology in the domestic shoe industry. The 3D producing process; 3D scanning, 3D modeling and 3D printing is expected to utilized widely in the fashion industry within the nearest future.

This paper proposes an IoT-based indoor autonomous driving system that applies SLAM (Simultaneous Localization And Mapping) and Navigation techniques in a ROS (Robot Operating System) environment based on TurtleBot3. The proposed autonomous driving system can be applied to indoor autonomous wheelchairs and robots. In this study, the operation was verified by applying it to an indoor self-driving wheelchair. The proposed autonomous driving system provides two functions. First, indoor environment information is collected and stored, which allows the wheelchair to recognize obstacles. By performing navigation using the map created through this, the rider can move to the desired location through autonomous driving of the wheelchair. Second, it provides the ability to track and move a specific logo through image recognition using OpenCV. Through this, information services can be received from guides wearing uniforms with the organization's unique logo. The proposed system is expected to provide convenience to passengers by improving mobility, safety, and usability over existing wheelchairs.
