This paper proposes a path planning algorithm for dispensers to increase the productivity in printed circuit board assembly lines. We analyze the assembly sequence of the dispenser, and formulate it as an integer programming problem. The mathematical formulation can accomodate multiple heads and different types of heads through extended cost matrix. The TSP algorithms are then applied to the formulated problem to find the near-optimal solution. Simulation results are presented to verify the usefulness of the proposed scheme.

Laryngeal amyloidosis is a rare benign disease. It is characterized by extracellular deposition of homogeneous and eosinophilic protein material in the form of fibrils. Diagnosis of this disease is made by histologic examination of involved tissue. It is ususlly primary or localized but rarely associated with a systemic or generalized disease. We present a case of primary laryngeal amyloidosis that was treated with KTP 532 laser vaporization.

For an efficient operation of today's power system, power engineers are required to analyze enormous amount of data. Owing to the development of technology, a variety of power systems computational tools have been developed and commercialized. However, the practical use of computational tools not only requires that people be able to understand the results the tools produce but also extract the required information from the simulation results which generally involves massive amount of information. This paper introduces a novel interface that would complement the drawbacks in the visualization of data of the pre-existing tools and assist the user in readily retrieving the required information, in this case the rotor angle data, of the simulated system thereby making power system analysis more feasible to be effectuated.

In this paper, an analysis is being performed on the effect of harmonics on loads in a distributed generation environment which includes renewable energy sources such as wind farms. The paper will assess the limits of the harmonic content that is allowed to be present in the adjacent loads while conforming to the distributed generation connection standards. The analysis is being performed in PSCAD/EMTDC where field measurements of wind data is being employed for the study.

Korea has recently seen reduction in Gihyeolbujog(氣血不足)-related woman disease due to low birth rate and elevated nutritional intake. In particular Uterine Prolapse usually result from malnutrition in days of need and also from earlier resumption of social activity after childbirth. Nowadays some women still develop Uterine Prolapse, of which the reasons are earlier resumption of social activity after childbirth, malnutrition due to harsh diet, contaminated food, and Gihyeolbujog by stress. This research has determined that GamibojungiggiTang would be effective for the treatment of those diseases. This research found that the combination of BojungiggiTang with Sugjihwang(熟地黃)and Noggaggyo(鹿角膠), which were used for Sinsubujog(腎水不足) and IghyeolbojeongJe(益血保定劑). Respectively, produced satisfactory treatment outcomes for prolapse.

The present study was undertaken to classify and describe the weed communities of the fields in Korea by methods of the ZM school of phytosociology. On the basis of the data obtained, the following vegetation units were recognized: A. summer weed community of rice field A-1. Oryzetea sativae: Sagittario-Monochorietum, A-2. Lemnetea minoris: Lemna paucicostata-Spirodela polyrrhiza community B. spring weed community of rice field B-1. Bidentetea tripartitae: Stellario-Ranunculetum cantoniensis C. summer weed community of arable land C-1. Chenopodietea Pinellio ternatae-Euphorbietum pseudochamaesyceslsynonym: Acalypho australis-Digirietum pectiniformis and Cephalonoploso segetti-Geranietum eriostemonii of North Korea in Dostal다 et al.(1990)] and Phyllantho urinariae-Lindernietum crustaceae D. weed community of fallow field D-1. Erigeron sumatrensis-Erigeron anmus community, D-2. Digitaria adscendens-Portulaca oleracea community, D-3. Chenopodium album community, and D-4. Erigeron canadensis-Erigeron annuus community. Generally compared to the Korean Peninsula, the weed communities in the fields of Cheju Island is much plentiful in their species composition.
