Since korean mobile communication companies each use different mobile platforms, developers must configure and translate their game contents to run under each of the smart phone platforms so that they can be serviced correctly. Nevertheless, such translation tasks require lengthy times and costs. This is one of the reasons why a variety of contents could not be provided. In order to mitigate such difficulty, this paper implemented the mobile contents converter system that converts mobile game contents of the GNEX platform to smart phone contents of the iPhone platform(iOS). The GNEX-to-iPhone automatic mobile contents translation system helps minimize the amount of time and cost required in servicing contents to different mobile communication companies by promptly translating platform-specific-contents to run under iPhone smart phone platforms. Also, the automatic translation and servicing of existing contents increases the reusability of these contents and also the productivity of new contents thereby offering users with a more variety of games.

In order to investigate the content of heavy metals in soil according to vertical profiles, 72 soil samples were collected from 4 sampling sites : Ulchiro-2 ga, Dugdo, Sungnaedong, and Amsa- dong. The content of mercury was measured by a mercury analyzer and those of lead, copper and zinc were measured by an atomic absorption spectrophotometer. From the results of this study, it was shown that the content of heavy metals decreased gradually from the surface soil to the 2 m- depth soil. But, there was no difference in the contents of the heavy metals in the 3m, the 4m and the 5m-depth soil.

Since Korean mobile communication companies each use different mobile platforms, developers must configure and translate their game contents to run under each of the platforms so that they can be serviced correctly. Nevertheless, such translation tasks require lengthy times and costs. This is one of the reasons why a variety of contents could not be provided. In order to mitigate such difficulty, this paper implemented an automatic mobile contents translating system that automatically translates mobile C game contents of the GNEX platform to mobile java contents of the WIPI platform. The GNEX C-to-WIPI Java automatic contents translation system helps minimize the amount of time and cost required in servicing contents to different mobile communication companies by promptly translating a platform-specific-content to run under other platforms. Also, the automatic translation and servicing of existing contents increases the reusability of these contents and also the productivity of new contents thereby offering users with a more variety of games.

The seven trace metals contents of agricultural products in Kwang-ju were investigated to provide the basic data for its residual limits. Ten kinds of agricultural products (onion, welsh onion, garlic, lettuce, cabbage, pepper, spinach, radish, pear, peach) collected within from Kwang-ju in 1999 were analyzed by Mercury Analyzer for mercury. Inductively Coupled Plasma spectrometer and Atomic Absorption spectrophotometer equipped with Vapor Generation Accessory for Cu, Cd, Mn, Pb, Zn and As. Hg contents were not detected in all samples and As content were detected N.D. ∼0.005 ppm. Cd and Pb contents were detected N.D ∼0.088 ppm and N.D.∼0.096 ppm, respectively, Cu, Mn and Zn contents were 0.109∼1.072 ppm. 0.829∼6.195 ppd and 0.731∼6.176 ppm, respectively. The trace metal concentrations of the agricultural products in Kwang-ju called clean area were within the background level which growth is facilitated.

To know a degree of pollution in agricultural products cultivated around 4 unworked mines located in Chollanam-Do, we investigated a concentration of heavy metal and trace metal to provide the basic data for its residual limits. 28 samples of seven kinds of agricultural products(lettuce, onion, potato, radish, pepper, pumpkin, bean) collected from 4 unworked mines located in Chollanam-Do in 2001 were analyzed by Mercury Analyzer for mercury and Atomic Absorption spectrophotometer for Pb, As, Cd, Cu, Mn, and Zn. Hg contents were detected N.D. ∼trace level(0.01 ppm and less) and As content were detected N.D. ∼ 0.029 lpm but most of same)leE were not detected. Cd contents were detected N.D∼0.124 ppm. The results of Hg, As, Pb and Cd content showed that for all the 7 species of agricultural products studied, none have accumulated levels dangerous enough to Pose health problems. The average contents of Cu were 3.070 ∼ 7.825 ppm in bean, the Mn were 3.688 ∼23.935 ppm in lettuce ailed the Zn were 5.690 ∼21.171 ppm in bean, respectively.

This study was conducted to determine the contents of heavy metal in commercial herbal medicines. The monitoring of lead, arsenic, cadmium and mercury was carried out on 100 samples with 10 kinds of herbal medicines. The contents of heavy metal were measured by inductively coupled plasma atomic emission spectrometry (ICP-AES) and mercury analyzer. The mean values of heavy metal contents for herbal medicines were Pb 1.87 mg/kg, As 0.39 mg/kg, Cd 0.26 mg/kg and Hg 0.021 mg/kg. Of the total samples, 19 samples (19%, 4 types) were violated the KFDA regulatory guidance of heavy metal in herbal medicines (9 samples on Pb, 10 samples on Cd). Among these 19 unsuitable samples, 16 samples were domestic and 3 samples were imported. Therefore, we need continuously monitoring to ensure confidence and safety for these herbal medicines.

In this paper, we describe a software implementation of a digital TV stream analyzer that can be used for analyzing and verifying digital TV bitstreams on personal computes. It accepts as input MPEG-2 transport streams (TS's) already stored on hard disks and doesn't require any special hardware. After classifying TS packets into program specific information(PSI) TS section auido, video, program clock reference (PCR) private data and null packets, it displays their contents through a graphic user interface along with the syntax elements of the TS header. Also it displays the decoded I frame nearest in time axis the TS packet currently shown This feature helps pin pointing the specific location of problematic parts in bitstreams. The bitsteam analyzer provides the compliance test of MPEG-2 Systems standard and the data injection functionality with which one can easily insert additional data to existing MPEG-2 bitstreams. Using the resulting system one can produce at low test streams for interactive broadcasting and data broadcasting for laboratory use.

Based on deep learning technology, speech recognition method has began to be applied to commercial products, but it is still difficult to be used in the area of VR contents, since there is no easy and efficient way to process the recognized text after the speech recognition module. In this paper, we propose a Korean Language Command System, which can efficiently recognize and respond to Korean speech commands. The system consists of two components. One is a morphological analyzer to analyze sentence morphemes and the other is a retrieval based model which is usually used to develop a chatbot system. Experimental results shows that the proposed system requires only 16% commands to achieve the same level of performance when compared with the conventional string comparison method. Furthermore, when working with Google Cloud Speech module, it revealed 60.1% of success rate. Experimental results show that the proposed system is more efficient than the conventional string comparison method.
