In order to provide technical financial support to small and medium-sized venture companies based on technology, the government implemented the TCB evaluation, which is a kind of technology rating evaluation, from the Kibo and a qualified private TCB. In this paper, we briefly review the current state of TCB evaluation and available indicators related to technology evaluation accumulated in the Korea Credit Information Services (TDB), and then use indicators that have a significant effect on the technology rating score. Multiple regression techniques will be explored. And the relative importance and classification accuracy of the indicators were calculated by applying the key indicators as independent features applied to the generalized boosting model, which is a representative machine learning classifier, as the class influence and the fitness of each model. As a result of the analysis, it was analyzed that the relative importance between the two models was not significantly different. However, GBM model had more weight on the InnoBiz certification, R&D department, patent registration and venture confirmation indicators than regression model.

In flip chip technology, the conventional solder bump has been replaced with a copper (Cu) pillar bump owing to its higher input/output (I/O) density, finer pitch, and higher reliability. However, Cu pillar bump technology faces several issues, such as interconnect shorting and higher low-k stress due to stiffer Cu pillar structure when the conventional reflow process is used. Therefore, the thermal compression bonding (TCB) process has been adopted in the flip chip attachment process in order to reduce the package warpage and stress. In this study, we investigated the package warpage induced during the TCB process using a numerical analysis. The warpage of the TCB process was compared with that of the reflow process.

Bronchial artery embolization (BAE) is a well accepted and effective treatment for massive and recurrent hemoptysis. However, several complications of BAE have been reported. Cortical blindness is defined as a loss of vision caused by bilateral occipital lobe lesions with normal pupillary light reflexes and a normal fundus. The reported incidence of transient cortical blindness(TCB) after cerebrovertebral angiography is approximately 1%. Two cases of TCB after BAE were found from a Medline search. Here, we report another case of TCB who was treated with BAE for a massive hemoptysis.

RTOS in the embedded system is a powerful tool for the design of multi-tasking. However, previous RTOS has large proportion in the MCU with limited memory. So it is difficult to apply RTOS. In this paper, I removed less frequently used features from the traditional RTOS, and designed lightweight RTOS that schedules and manages the resources with minimal code. I used techniques to obtain user memory using sharing stack, and to reduce the overhead at context. Considering ratio of kernel and applications, the RTOS designed in this paper is available on the MCU with more than 4KB of program memory.

Purpose: The purpose of the study is to investigate the relationship between total serum bilirubin(TSB) and transcutaneous bilirubinometry(TcB) in neonates with jaundice. Method: TcB from various sites(forehead, sternum, abdomen, buttock, hand, dorsalis-pedia) was measured using a JM-102 in a total of 102 neonate, 42 female and 60 male, with the mean 37.5 gestational week and the mean 2,903 gram of birth weight, as well as TSB from capillary punctures. Result: The mean bilirubin was 11.73 in serum, 20.55 on the forehead, 17.23 on the sternum, 16.19 on the abdomen, 18.22 on the buttock, 15.83 on the hand and 15.49 on the dorsalis-pedia. The relationship between TSB and TcBs were formulated by simple regression with 0.406 < r < 0.668(p < .000). A higher relationship was revealed between TSB and TCB at the forehead in infants of full-term, ABO incompatibility, and Hb greater than 16 mg/dl(r =0.725, 0.790, and 0.717, retrospectively). Phototherapy altered the measurement of TcB per site. Conclusion: TcB on the forehead is a reliable, noninvasive and convenient measurement of TSB in normal infants(Institutions need to establish quantitative equations representing the specific relationship between TSB and TCB according to the hemodynamic problems of infants such as ABO incompatibility, or low Hb).

This case study introduces the process of developing the technology rating evaluation model for investment. The technology evaluation rating model for investment is a project that the Financial Services Commission and the Ministry of Commerce, Industry and Energy collaborated to expand the scope of technology finance from loan to investment. The technology evaluation model for investment was developed with the aim of predicting high growth companies. The model consists of a statistical model and an expert model. Here, statistical models were modeled by using logistic regression analysis. Expert models gathered opinions of experts and identified the weight of each evaluation item and set the model. The rating system of the model is composed of 10 grades. The distribution of the model was consistent with KTRS grade distribution. Interestingly, the emphasis is on technology and marketability. In the technology valuation grade model for the goddess, there is a considerable difference from the emphasis on managerial competence or business performance.

Introduction Jaundice is one of the most common conditions found in neonatal period. Phototherapy is one of the main treatments for neonatal jaundice. However, several adverse effects of the phototherapy have been reported, including DNA damage recently. Therefore, a variety of treatments have been conducted to shorten the duration of phototherapy. Meanwhile, it has been hardly tried to prevent neonatal jaundice, but diverse approaches have been tried in traditional Chinese medicine (TCM) for many years. Therefore, this study aims to analyze the studies for the treatments to prevent neonatal jaundice based on TCM. Materials and Methods Various literatures have been searched via CNKI, and PubMed using the terms "neonatal jaundice" (新生儿黄疸, 胎黃, 胎疸) in category of 'Traditional Chinese Medicine', 'Traditional Chinese Medicinal Herbs' and 'Combination of Traditional Chinese Medicine With Western Medicine'. The search range included randomized controlled trials (RCTs), controlled clinical trials (CCTs), case reports, reviews and animal experiments published from 2013 to 2015. Results A total of 104 studies were found. 93 articles were excluded by reviewing the titles and abstracts. Out of the remaining 11 studies, 9 articles were RCTs, 2 articles were CCTs. The treatment used in neonatal babies in the studies were, using herbal remedies (meditation 5, bath 3 and retention enema 1) and the acupressure. All treatments were initiated within the first 24-48 hours after their birth. Then, there was a study that the subjects taken the herbal medicine were women during pregnancy. The outcome assessments used were the serum total bilirubin (TB), transcutaneous bilirubin measurement (TCB), the incidence of the hyperbilirubinemia, the duration time of the jaundice. Especially, TB, TCB and the incidence of the hyperbilirubinemia have decreased significantly more than that of the control group in the most of the results. No severe adverse events were reported in all articles reviewed. Conclusions Conventional treatment such as, herbal medicine in TCM, seems to be the effective way to prevent neonatal jaundice or hyperbilirubinemia. Therefore, the conventional treatment may be favorable choice for preventive treatment for neonatal jaundice.

Ohba has suggested the Colored Thread Algorithm to prevent looped path when LSP is to be setup. M immediate node sends thread information such as color, hop count. ill, to downs1ream node via LDP message for the set-up of LSP. Afterward, decides that the looped path is formed when it receives a message with a same colored thread that was sent to downs1ream node, and it searches another path. If the message reaches to the egress node, then acknowledged message is sent to upstream node as reverse direction to the ingress node to set up loop-free path. For the algorithm, Ohva has defined three thread states as Null, Colored, Transparent. In this paper, the state of thread is extended to 5 states such as Extending, Merging, Stalling, Null, and Transparent. By the way, related FSM and TCB was redefined to make clear the ambiguity of thread states which causes faulty actions and to remove overhead. And, to improve performance, it limits to generate a thread in the state of Stalling.
