  • Applying predictive analytics to enterprise processes is an effective way to reduce operation costs and enhance productivity. Accordingly, the ability to predict business processes and performance indicators are regarded as a core capability. Recently, several works have predicted processes using deep learning in the form of recurrent neural networks (RNN). In particular, the approach of predicting the next step of activity using static or dynamic RNN has excellent results. However, few studies have given attention to applying deep learning in the form of dynamic RNN to predictions of process performance indicators. To fill this knowledge gap, the study developed an approach to using process mining and dynamic RNN. By utilizing actual data from a large domestic company, it has applied the suggested approach in estimating timely stocking in purchasing process, which is an important indicator of the process. The analytic methods and results of this study were presented and some implications and limitations are also discussed.

  • This work was carried out to investigate performance and carcass yield of large-type broiler females at different stocking densities. Chicks (n = 492; 1-day-old; female; Arbor Acre broiler) were reared for six weeks (starter, 0~1 wk; earlier, 1~3 wk; finisher, 3~6 wk) and randomly divided into 3 treatments (4 replications/treatment, 36, 41 or 46 birds/replication). Treatments were T1 (10.9 birds/$m^2$), T2 (12.4 birds/$m^2$) and T3 (13.9 birds/$m^2$) by the stocking densities. Research indexes were livability, body weight, body weight gain, feed intake, feed conversion ratio, production efficiency factor, carcass yield and primal cuts ratio (wing, leg, back, breast and neck). Livability (%) was 90% or more for all treatments, but there was no significant difference on weekly livability (%). Body weight of T3 treatment were the lowest at 3 wk and body weight gain, feed intake, and feed conversion ratio were the lowest at 2~3 wk (P<0.05). Production efficiency factors of T1, T2 and T3 were 331.0, 340.8 and 336.0, respectively, and there was no significant difference among treatments. Leg meat ratio of T2 treatment was higher compared to other treatments at the age of 4 wk (P<0.05). Carcass yield of T1 treatment was the highest as 76.2% at the age of 5 wk (P<0.05). However, there was no significant difference on carcass ratio and partial meat ratio among treatments at the age of 6 wk. This result may provide the standard data of different stocking densities for heavy female broilers.

  • This study was carried out to investigate the effects of stocking density on the eating and ruminating behavior of growing Hanwoo steer (Bos taurus coreanae). A total of thirty growing Hanwoo steers were divided into four stocking density groups (G1: 1 head/32 $m^2$, G2: 2 heads/32 $m^2$, G3: 3 heads /32 $m^2$, G4: 4 heads/32 $m^2$) with 3 replicates (12 pens). The results of eating behaviors for 48 hours are summarized as follows: Total intake was higher in 2G, 3G and 4G than in 1G, but not significantly different among thetreatments. Intake of roughage was the highest in 2G (3.32 kg), while 1G (2.85 kg) was the lowest (P<0.05). Eating time of concentrate was highly in the order of 1G > 2G > 3G > 4G (P<0.05). But eating time (concentrate + roughage) and ruminating time were not significantly difference among the treatments. Resting time (standing + lying) was the highest in 4G (P<0.01), and lying time was the highest in 2G. Chewing time (Eating + ruminating) was higher in 3G than in 1G, 2G, and 4G (P<0.05). Number of bolus, number of total chews, ruminating time per bolus and number of bolus per minute were not significantly difference among the treatments. But number of chews per bolus was significantly lower in 1G than those of the other treatments (p<(0.05). Number of urinating was in the order of 1G > 4G > 2G > 3G (P<0.05). However, stocking density had no effect on drinking and defecating. Eating rate and chewing efficiency were the highest in 4G (P<0.01, 0.05), but ruminating efficiency was not significantly difference among the treatments.

  • Multipurpose fisheries base was conceptually designed to establish marine ranching system in the coastal waters around Tongyoung, southern sea of Korea. Fisheries base for marine ranching system has integrated various facilities which were required for the process of spawning, rearing, training, releasing, monitoring and catching functions. This base has five steel piles for supporting upper structure and systems. Four steel piles are surrounded by circular net pen made by steel wire, they have the function of the protection against fouling for pile and scouring for bottom soil as well as secondary rearing and short stocking. We can use the last pile to moor a ship and access to the base. Principal structure with steel piles is designed by optimization technique considering design external forces in the coastal waters of return period of 50 years. Design optimization Problem is formulated for this base. Optimal design of multipurpose fisheries base is numerically investigated by sequential quadratic programming method.

  • The purpose of this article was to provide basic knowledge and treatment principles of patient with lymphedema, which was usually not treated at all, or the treatment given didn't work efficiently. Lmphedema is defined as an abnormal accumulation of protein-rich fluid, edema, and chronic inflammation within an extremity. Lmphedema may be classified as either primary results from defects with aplasia, hypoplasia, and hyperplasia in the lymphatic system at birth or secondary is caused by known precipitating factors such as cancer, infection, inflammation, radiation, surgery, or trauma etc. There are essentially several conservative treatment methods which has been utilized successfully to treat lymphedema in Samsung Medical Center. We used following procedures: CPT (Complex Physical therapy) or CDP (Complex Decongesitive Physical therapy) such as skin care, MLD (Manual Lymph Drainage), compression with short-stretch bandage, exercise, elevation, elastic stocking, and pneumatic compression. Our experiences shows that conservative treatments can significantly reduce lymphedema and prevent different complications.

  • The author introduces the preventive and therapeutic methods of diseases in Japanese flounder which have been conducted by the Fish Disease Laboratory, the Mikamewan Fishery Cooperative Union, Ehime Prefecture, since 1982. Prevention 1. Addition of a sand substrate in the culture pond was effective to prevent ulcer disease. 2. Bathing in 0.5ppm of copper ion was effective to prevent some parasites. 3. Low stocking density of the fish reduced an incidence of edwardsiellosis or gliding bacterial disease. 4. Removal of the diseased fish prevented thd spread of lyphoeystis. 5. So-called $\pi$-water was effective to prevent the fry from some diseases. 6. Immersion of the juvenile in a sodium nifrusylate solution during transportation was effective to prevent gliding bacterial disease. Therapy 1. Sodium nifrustylate or oxytetracycline was effective to cure gliding bacterial disease. 2. Bathing in formalin(150ppm) or freshwater was effective to cure scuticociliatidosis. 3. Erythromycin was effective to cure $\beta$-hemolytic Streptococcus sp. infection. 4. Bathing in a hydrogen peroxide solution(1.5%) was effective to cure white spot disease.

  • This paper examines a deterministic, discrete-time, finite-horizon, production/distribution problem for a one-plant multi-retailer system. Production may occur at the plant in each time period. Customer demands at each retailer over a finite number of periods are known and must be met without backlogging. The plant as well as the retailers can serve as stocking points. The problem is to find a minimum-cost production/distribution schedule satisfying the known demands. We show that under a certain cost structure a nested policy is optimal, and present an efficient algorithm to find such an optimal policy. Planning horizon results and some computational saving schemes are also presented.

  • Recently, many organizations in various industries have introduced e-businesses for the purpose of adding value to their businesses. However, due to no comparable business models to e-business in the past, there are no reliable yardsticks to predict the performance of an e-business. This paper considers an environmental change analysis as a means to resolve this difficulty. System Dynamics (SD) could be a useful tool to generate effective results by examining the e-business model. SD model is developed to analyze the effects of an e-sales channel which was appended to the existing sales channels in the steel manufacturing industry. The results show an increase in average price and sales volume through the use of an auction process on the e-marketplace. Stocking expenses are reduced as well by the increase of the sales turnover. A possible scenario was adopted to the developed simulation model and investigated strategic issues to draw desirable strategies with market changes.

  • Nylon fabric is widely used in stocking, inner wear, sports wear, and casual wear, but has a defect of easy electric static charging. Accordingly there has been great demand for the hydrophillic finishing technology that could be applied to nylon fiber more easily and efficiently. In this study, ethoxylated hexylantinoanthraquinones were exhausted onto nylon from aqueous bath, and hydrophillicity of the nylon was discussed. In the treatment of nylon fabrics with ethoxylated hexylaminoanthraquinones, they were successfully exhausted onto nylon fabric without any aid of chemical auxiliary. The hydrophilicity of the dyed nylon fabrics were increased with the length of ethoxylate chain. The durability of antistatic and hydrophilic characteristics was good enough as to maintain the initial properties even after 30 repeated launderings.

  • Less researches on AGV(Automated Guided Vehicle) path configurations have been conducted so far while more studies have been placed in determining AGV guide path directions and pick-up/drop-off station locations, and routing/dispatching/scheduling strategies. In practice plenty of concerns fall in preventing deadlock and simplifying AGV system control through an appropriate AGV path configuration. In order to meet those requirements, a new AGV path configuration, inter-loop stocker type is introduced here. The stocker serves as relaying material between loops as well as stocking material. Automated material handling systems using AGVs play an important role in semiconductor industry including TFT LCD and memory/non-memory chip. A practical example of implementing the inter-loop stocker concept successfully in the TFT LCD fab is presented in this paper.
