Food labelling is the primary means of communication between the producer and purchaser and plays an important role in consumer's choice of food. Food labelling applying to livestock products, such as meat products (ham, sausage etc.), milk products(milk, fermented milk, butter and cheese etc.) and egg Products is regulated by 'Livestock Products Labelling Standard', National Veterinary Research & Quarantine Service (NVRQS) Notification. This study presents the principles of Korean milk products labelling provision and its recent revision to prevent consumer from misunderstanding and facilitate fair trade practices in market and also keep consistencies with international and relative national regulations. This study also suggests milk products labelling policy direction in the future.

The determination of response characteristics for pressure sensors is routinely limited to static calibration against a deadweight pressure standard. The strength of this method is that the deadweight device is a primary standard used to generate precise pressure. Its weakness lies in the assumption that the static and dynamic responses of the sensor in question are equivalent. Differences in sensor response to static and dynamic events, however, can lead to serious measurement errors. Dynamic techniques are required to calibrate pressure sensors measuring dynamic events in milliseconds. In this paper, a dynamic calibration using negative going dynamic pressure is proposed to determine dynamic pressure response for piezoelectric sensors. Sensitivity and linearity of sensor by the dynamic calibration were compared with those by the static calibration. The uncertainty of calibration results and the goodness of fit test of linear regression analysis were presented. The results show that the dynamic calibration is applicable to determine dynamic pressure response for piezoelectric sensors.

1. To define 'Korean medicine industry' through study on existing medicine related industries, Korean medicine industry means all industrial activities related to Korean medicine. It covers material resources such as herbs and products made with herbs, medical instruments, Korean medical service and related information service based on Korean medicine theories. 2. According to Korea National Statistical Office standard industrial branch, Korean medicine industry was classified as a large branch. There were industries such as agriculture, food and beverage manufacture, publishing, copy of prints and record media, manufacture of compound and chemical products, medical service, manufacture of precise optical instruments, wholesale trade and product mediation, retail trade, restaurant, research and development, education service, health preservation service, entertainment, culture and sports industry related to the Korean medicine industry. 3. If we classify this according to the industry branch of English economists Clark, Colin Grant, herb cultivating industry will be classified as primary industry, manufacture of foot and beverage related to Korean medicine, secondary industry and wholesale and retail sales of herb, research and development, education, health preservation, social welfare, tertiary industries.

The mass measurement of solid density standards using weight exchanger is described. KRISS(Korea Research Institute od Standards and Science) has several solid density standards. Their mass have been measured manually only using a mass comparator(Mettler, 1kg - 0.01mg). However, the uncertaity of the manual mass measurement is up to 300 microgarm much more than 32 microgram of advanced NMIS(National Metrology Institutes) for 1 kg silicon sphere which is primary density standards due to an eccentric error and buoyancy correction error. The new system with a weight exchanger is designed and built to improve the measurement accuracy. It comprises a weight exchager, a mass comparator, air density instruments, and application program for automatic measurement. It is evaluated by measuring several elements in an air tight chamber to verify the performance of it.

The successful launch of Arirang satellites allow the acquisition of high resolution satellite imagery of Korean territory and enables the transition from the conventional cultivation area survey method to new image based methods adopted in advanced nations. In this study, we suggested reasonable sizes of the primary sampling unit and the secondary sampling unit for the satellite imagery based sampling design in 8 provinces preselected for this research. The PSU size was determined mainly in consideration of intracorrelation that shows the degree of homogeneity within each cluster and the efficiency of the image process. For the SSU size, we considered the relative standard error and the differences between the land cover maps produced by the Ministry of Environment and the satellite imagery processed by the National Statistical Office.

The latest version of the HLA(High Level Architecture) standard developed by the US Department of Defense was established as an open and internal IEEE 1516 HLA standard in 2000. Commercial applications based on the IEEE 1516 have already developed in the non-defense industry. We participated in several development projects for NTS (Nuclear Training Simulator). Extensive modifications are necessary to make a new and/or upgraded NTS because the previously developed simulation softwares have not two desirable property: reusability and interoperability. We reviewed the IEEE 1516 specifications to develop NTS having the capability of reusability and interoperability. Our review activities were forced on application development process, supporting tools, and software structure of NTS. The primary goal of this review is to identify what are constraints or problems to be resolved when we apply IEEE 1516 to NTS development. In this paper we suggest several recommendations for NTS developers.

Reliable and fine-grained musical metadata are required for efficient search of rapidly increasing music files. In particular, since the primary motive for listening to music is its emotional effect, diversion, and the memories it awakens, emotion classification along with genre classification of music is crucial. In this paper, as an initial approach towards a "ground-truth" dataset for music emotion and genre classification, we elaborately generated a music corpus through labeling of a large number of ordinary people. In order to verify the suitability of the dataset through the classification results, we extracted features according to MPEG-7 audio standard and applied different machine learning models based on statistics and deep neural network to automatically classify the dataset. By using standard hyperparameter setting, we reached an accuracy of 93% for genre classification and 80% for emotion classification, and believe that our dataset can be used as a meaningful comparative dataset in this research field.

The present study was performed to establish the cephalometric standards of linear measurements in Hellman dental age II C groups of Korean on the roentgenocephalometry. The subjects consisted of 21 males 31 females with normal occlusion and acceptable profile. The major conclusions were as follows. 1. The means and standard deviations of the measurements in males and females were made. 2. No sex difference was made in all items, except in U₁-Y and U₁-X.

In this paper, a random subset selection procedure for the choice of the k best objects out of n primary measurements $Y_t$ is considered when only the associated measurements $X_t$ are available. In contrast to Yeo and David (1992), where only the ranks of the X's are needed, the present uses the observed X-values. The approach is illustrated numerically when X and Y are bivariate normal and the standard deviation of X is known.

This study presents a discrete optimization of tall steel buildings under multiple drift constraints using a dual method. Dual method can replace the primary optimization problem with a sequence of approximate explicit subproblems. Since each subproblem is convex and separable, it can be efficiently solved by using a dual formulation. Specifically, this study considers the discrete-optimization problem due to the commercial standard steel sections to select member sizes. The results by the proposed method will be compared with those of the conventional optimality criteria method
