The microfluidic controlled droplet manufacturing system is one of the most powerful methods for capsule manufacturing. The microfluidic control method can control the type and size of the capsule by changing the size and configuration of the channel. In addition, by increasing the number of channels, capsules of uniform size can be mass-produced. In this paper, a capsule manufacturing system including flow-focusing and T junction method was designed. In addition, the effectiveness of this system was verified by manufacturing multi-emulsion capsules with a size of 2.2 to 3 mm.

The microfluidic controlled droplet production system is one of the most powerful methods for capsule manufacturing. However, stable production is not possible when the powder is included. We solved the above problem by developing an off-chip droplet production system. we checked the droplet creation mechanism and created a simple repair model. It was possible to produce a uniform and stable droplet regardless of the powder content.

The home network environment based on the power line communication has some unexpected events. The noise source from the home appliances makes the network impedance increased, and the transmission packets distorted. Therefore the packet transmission from the source node may not be delivered to the destination node directly. In this paper we propose a new self-healing mechanism which relays the packet to the directly unreachable destination automatically with the help of intermediate nodes. In order to choose the minimum required intermediate nodes our mechanism makes a spanning tree with both the directly reachable nodes and indirectly reachable nodes via the intermedia nodes. We developed the network simulator in order to compare its performance to the Echelon's repeater selecting mechanism. Though it required more packet relations than Echelon's but the reachable probability to the destination was highly increased about two times.

This study examines the process of internalization and elaboration of the logic of competition in the post-IMF era through the genealogy of the survival program. Post-IMF is based on disaster reality, which reveals a specific emotional structure related to the competition, if the narrative of overcoming the IMF event finds narrative models that can be sufficiently reconciled between communityism and individual success. This study also examines the process of disaster preparedness through survival form and narrative structure embedded in such form. Thus, this study reconstructed the diachronic change to track the change of the survival program and the subsequent narrative change. Relative to the time of the healing-mentor, the survival program seems to be declining, but rather seems to have created a new transition through the logic of self-development contained in the healing-mentoring discourse. this logic leads to be ghettoized hierarchy of preferences. Now, the survival program is to perform fantastic surrogate satisfaction by delegating competition to a narrow self-directed area rather than to a big empathy within the community.

Purpose: This study explored the experiences of pregnant women with depressed mood participating in a group cognitive behavioral therapy (CBT) program using video communication, based on Beck's cognitive theory. Methods: The participants were six pregnant women out of 13 women who had participated in an 8-session group CBT program using video communication for women with depressed mood (Edinburgh Postnatal Depression score of ≥9). Data were collected from February 20 through March 25, 2021. In-depth individual interviews were conducted through a video conferencing platform at 1 month post-baseline. Thematic analysis was done. Results: Three themes, 10 subthemes, and 38 concepts were derived from experiences of participating in the 4-week group CBT program (twice a week). The first theme, entitled "continuing realization" had subthemes of "a negative and instable self," "a selfish judgment that excludes others," and "a strong belief in self-control." The second theme, entitled "attempt to change for restoration" had subthemes of "shift to rational thinking," "freedom from suppressed beliefs," "tolerance of other people," and "courage for self-expression." The third theme, entitled "departure for a positive life," had subthemes of "emotional healing," "faith in oneself," and "reestablishing the criteria for happiness." Conclusion: Pregnant women with depressed mood expressed that continuing realizations and attempts to change supported their transition toward a positive direction of healing. Thus, they were able to change their distorted thinking into rational thinking through CBT using video communication. These findings support the use of group CBT using video communication with pregnant women who have depressed mood.

This study is focused on defining what is their career goals and the standard to set up the goals as an individual married immigrant women. Marriage immigrant women are expected to have higher difficult than Korean women do in reality, so the research will figure out what career goal marriage immigrant women have to achieve the goal. As the results, the data has been collected from seven of the married immigrant women through in-depth interview, the conclusion is as followed: First, career goal for married immigrant women turns out self-reliance and valuable life. Career is used in wide spread range including a job, and their career goal is for being a self-employed, a travel guide, an english teacher, and a regular worker. They have various goal for valuable life to feel that their living is better than monetary stuff, to have a healing tour through music, and to exchange with foreign scholars and train junior scholars. They hope they can be confident as a part of the Korean society and be able to help others and to see themselves as valued to live a life.

The syndrome of the trephined is a neurologic phenomenon that manifests as sudden decline in cognition, behavior, and sensorimotor function due to loss of intracranial domain. This scenario typically occurs in the setting of large craniectomy defects, resulting from trauma, infection, and/or oncologic extirpation. Cranioplasty has been shown to reverse these symptoms by normalizing cerebral hemodynamics and metabolism. However, successful reconstruction may be difficult in patients with complex and/or hostile calvarial defects. We present the case of a 48-year-old male with a large cranial bone defect, who failed autologous cranioplasty secondary to infection, and developed rapid neurologic deterioration leading to a near-vegetative state. Following debridement and antibiotic therapy, delayed cranioplasty was accomplished using a polyetheretherketone (PEEK) implant with free chimeric latissimus dorsi/serratus anterior myocutaneous flap transfer for vascularized resurfacing. Significant improvements in cognition and motor skill were noted in the early postoperative period. At 6-month follow-up, the patient had regained the ability to speak, ambulate and self-feed-correlating with evidence of cerebral/ventricular re-expansion on computed tomography. Based on our findings, we advocate delayed alloplastic implantation with total vascularized soft tissue coverage as a viable alternative for reconstructing extensive, hostile calvarial defects in patients with the syndrome of the trephined.

The present study aimed to examine the effectiveness of different techniques for controlling the diagonal cracks at the corners of openings on the strength, deformation, and crack propagation in reinforced concrete walls. The crack control strip proposed in this study, the conventional diagonal steel reinforcing bars, and stress-dispersion curved plates were investigated for controlling the diagonal cracks at the opening corners. An additional crack self-healing function was also considered for the crack control strip. To evaluate the volume change ratio and crack width propagation around the opening, downsized wall specimens with a opening were tested under the diagonal shear force at the opening corner. Test result showed that the proposed crack control strip was more effective in reducing the volume change and controlling the crack width around the opening when compared to the conventional previous methods. The crack control strip with crack healing feature displayed the superior performance in improving the strength of the wall and reducing the crack width while healing cracks occurred in the previous tests.

The study aim was to analyze research trends related to the effect of a forest healing program on humans. We analyzed 120 articles by focusing on "Journal information," "Characteristics of study participants," "Program characteristics," "Experimental design," and "Measurement indices." The numbers of papers published in the fields of agriculture and maritime were highest, and the numbers have increased since 1996 when the first paper was published. Many papers have targeted both sex (males and females), middle age, and healthy people. The programs were mainly conducted for multiple times in a forest welfare facility, and exercise therapy, psychotherapy, and plant therapy were primarily administered. Most studies compared experimental and control groups with < 30 participants, and mainly used self-reported surveys. The present study results are expected to be used as basic data for the development of forest healing programs and to expand related research in the future.
