Initial stage of emotion has a great influence on building up product image and impression. Because of its influencing effects, measuring initial stage of emotion has potential to be a key factor for designers and marketers to achieve a distinct product concept. While many researchers have studied this topic with the emotion measurement method in product use stage, there are very few cases specialized in the initial stage of emotion. Even though present emotion measurement methods have difficulties to derive accurate user's initial stage of emotion, most case of initial emotion study applies these defective methods. The purpose of this study is to develop initial stage of emotion measurement method and apply this method to real product context. In the design of the initial stage of emotion measurement method, noticeable characteristics of initial stage of emotion were explored and initial emotion measurement framework was presented. Based on this framework, Initial Emotion Measurement System(IEMS) was suggested. This method collects user's eye movement, behavior and verbal data accurately and objectively.

Currently, all design information of a hull structure is being first defined on 2D drawings not 3D CAD model at the initial ship design stage and then transferred to following design stages through the 2D drawings. This is caused by the past design practice, limitation on time, and lack of hull structural CAD systems supporting the initial design stage. As a result, the following design tasks such as the process planning and scheduling are being manually performed using the 2D drawings. For solving this problem, a data structure supporting the initial design stage is proposed and a prototype system is developed based on the data structure. The applicability of the system is demonstrated by applying it to various examples. The results show that the system can be effectively used for generating the 3D CAD model of the hull structure at the initial design stage.

The cell search scheme for W-CDMA consists of the following three stages: slot synchronization(1st stage), group identification and frame boundary detection(2nd stage), and long code identification(3rd stage). The performance of the cell search when a mobile station is switched on, which is referred to as initial cell search, is decreased by the initial frequency and timing error. In this paper, we propose the pipeline structured initial cell search scheme using time trackers to compensate for the impact of the initial timing error in the stage 2 and stage 3. The simulation results show that the performance of the proposed scheme is maximal 1.5dB better than that of the conventional one when the initial timing error is near ${\pm}T_c$/2.

In the initial ship design stage of shipyards, the hull form design, the basic design (compartment modeling and ship calculation), and the hull structural design are being performed by different systems. Thus, the problem on interfaces between these systems occurs. To solve this, we developed the hull form design system 'EzHULL' and the compartment modeling and ship calculation system 'EzCOM-PART' for developing finally an integrated ship design system. And, in this study, we present an object-oriented hull structural design .system 'EzSTRUCT', which is developed recently. A structural design in an initial design stage can be frequently changed, because the design is not firmly determined yet. Therefore, designers perform the simplified structural modeling with bigger structural parts (or objects) such as deck, longitudinal bulkhead, etc. in the initial design stage, and the detailed structural modeling with smaller structural parts such as plate, seam, slot, etc. in the detailed design stage. However, the existing hull structural CAD system used in a shipyard is not efficient in generating a 3D CAD model in the initial design stage, because it has difficulty in handling frequent changes in design. Therefore, designers initially draw 2D drawings in the initial design stage, and generate the 3D CAD model from these 2D drawings in the detailed design and production design stages. In this study, the hull structural design system, which can efficiently generate a 3D CAD model through rapid modeling at an initial design stage, was developed in this study To evaluate the applicability of the developed system, we applied it to hull structural modeling of various ships such as a VLCC, a bulk carrier, etc. As a result, it could efficiently generate a 3D CAD model of a hull structure.

This study was conducted to examine the effect of IgY supplementation on growth performance, blood metabolism, and disease occurrence in the weaned calves at 3 or 4 month of age. Average daily gain (ADG) and feed intakes were not affected by IgY supplementation, regardless of weaning months. White blood cell (WBC) count of the control group was higher in the final stage than in the initial stage (p<0.05), while that of the IgY supplemented group was lower in the final stage compared to the initial stage (p<0.05). regardless of treatments. Hematocrit (HCT) and red blood cell (RBC) counts were lower in the final stage than in the initial stage (p<0.05), but mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) counts were higher in the final stage than in the initial stage, regardless of treatments. In the control group, concentrations of albumin and globulin were higher in the final stage compared to the initial stage in the weaned calves at 3 month of age (p<0.05), and concentration of blood urea nitrogen (BUN) was increased in the IgY supplemented group. In the control group, concentrations of aspartate aminotransferase (AST) and gamma (${\gamma}$)-glutamyl transferase (GGT) were higher in the final stage compared to the initial stage (p<0.05). In contrast, concentrations of aspartate aminotransferase (AST) and gamma(${\gamma}$)-glutamyl transferase (GGT) were lower in the final stage compared to the initial stage for the IgY supplemented group. A diarrhea calf was only found in the control group. Manure score was higher in the control group compared to IgY supplemented group (p<0.05). Thus, these results indicates that IgY supplementation had positive effects on some blood metabolites, fecal condition score and diarrhea without negative effect on growth performance of the weaned Hanwoo calves.

For passenger vessels, twin shaft types in propulsion system is generally adopted to provide a high-speed performance in low draught due to restricted operating condition in harbors or water channels. Struts of twin open shaft type support the shafts, bearings, and propellers. Therefore, strut design is needed to consider not only hydrodynamic performance but also structural and noise/vibration performance, In this paper, considerations in strut design at the initial design stage have been discussed based on existing references, numerical calculations, and their comparisons. Also, the strut design of a RoPax ferry has been carried out at the initial design stage, for an example.

Purpose: Early detection of gastric cancer is important to improve prognosis. Early detection enables local treatment, such as endoscopic submucosal dissection (ESD). Therefore, we investigated whether early detection of gastric cancer could reduce healthcare costs by comparison according to stage and treatment modalities. Materials and Methods: Medical care costs were investigated according to tumor stage and initial treatment modality in 1,188 patients newly diagnosed with gastric cancer at 7 medical institutions from December 2011 to June 2012. Total medical care costs during the first-year after diagnosis (total first-year costs) were examined, including the costs of initial treatment, post-initial treatment, and inpatient and outpatient visits. Results: Stage I (75.3%) was the most common cancer stage. ESD was the second most common treatment following surgery. Total first-year costs increased significantly from stages I to IV. The costs of initial treatment and post-initial treatment were lowest in patients with stage I cancer. Among patients with stage I cancer, total first-year costs were significantly lower when treated by ESD; in particular, initial ESD treatment costs were much lower than others. Conclusions: The cost of healthcare has increased significantly with increasing cancer stages. ESD can greatly reduce medical care costs of gastric cancer. Thus, early detection of gastric cancer is important to reduce healthcare costs.

Backgrounds and Objectives: Squamous cell carcinomas of the oral cavity(SCOC) in TNM stage I & II have relatively high chance to be cured compared to those in the advanced stage, but sometimes result in the treatment failure with poor prognosis. There have been few reports on the patterns of failure and the clinical courses for SCOC in stage I & II after the failure of initial treatment. This study is directed at identifying the clinical outcomes of stage I & II SCOC and the salvage rate after initial treatment and suggesting an optimal level of treatment by analyzing the patterns of failure. Material and Methods: The medical records of 36 patients with SCOC, initially diagnosed between 1995 and 2001 as TNM stage I & II were reviewed retrospectively. The patterns of failure, salvage treatment, clinical courses, and the survival of these subjects were analyzed. The minimum follow-up period of no-evidence of disease(NED) was 12 months with an average of 32.2 months. Results: Overall rate of the treatment failure in SCOC of stage I & II was 41. 7%(15/36 cases). Most of the treatment failure in the subjects with stage I tumors occurred in regional lymph node. Local failure was the most frequent form of failure in the subjects with stage II tumors after wide excision of primary tumor with elective neck dissection and/or radiation therapy. No significant correlation was noted between the safety margin and the local failure. Elective neck dissections in stage I & II SCOC had a tendency to reduce regional failure (p=0.055). The salvage rates at 24 months were 85.7% in stage I, and 37.5% in stage II. The 3-year survival rate after the failure of initial treatment was 55.0%. Conclusion: SCOC of stage I & II after the failure of initial treatment showed poor prognosis despite of the salvage treatments. This study implies that the elective neck dissections for regional lymph node should be required for SCOC of stage I & II to reduce the treatment failure.

This study reviewed the use of soil injection materials using circulating resources as injection materials for the steel pipe multi-stage construction method. The tests performed were homogel time and homogel compressive strength. The steel pipe multi-stage construction method is an auxiliary construction method for tunnels, and the expression of initial strength after construction is an important factor. The better the strength development in the initial stage, the more it can be used as an injection material suitable for the multi-stage steel pipe construction method. As a result of laboratory test, it was found that the homogel time of the injection material using circulating resources required more time than the mixing ratio using cement as the injection material. In addition, it was found that the initial strength curing time satisfying 2MPa was required for more than 24 hours. Therefore, it was confirmed that the injection material using recycled resources required a longer initial curing time than cement of the same mixing ratio.

In this paper, the improved initial cell searching algorithm is proposed for 3GPP W-CDMA system. The key objective of the proposed algorithm is to utilize the reliability of the first stage of cell searching algorithm in order to accomplish the second stage. So the proposed algorithm makes the mobile station transfers to the second stage from the first stage, just after the slot synchronization is declared successively at the same time-offset. In order to compare the proposed algorithm with the conventional one, the simulations are accomplished for cell search algorithm for 3GPP W-CDMA systems in the multipath Rayleigh fading channel. Some parameters are also presented for the better performance in the initial cell searching algorithm.
